Why do we offer safe fabrics?

3 10 2016

Why do we say we want to change the textile industry?  Why do we say we want to produce fabrics in ways that are non-toxic, ethical and sustainable?  What could be so bad about the fabrics we live with?

The textile industry is enormous, and because of its size its impacts are profound.  It uses a lot of three ingredients:

  • Water
  • Chemicals
  • Energy

Water was not included in the 1947 UN Universal Declaration of Human Rights because at the time it wasn’t perceived as having a human rights dimension. Yet today, corporate interests are controlling water, and what is known as the global water justice movement is working hard to ensure the right to water as a basic human right.(1) Our global supply of fresh water is diminishing – 2/3 of the world’s population is projected to face water scarcity by 2025, according to the UN. Our global water consumption rose six fold between 1900 and 1995 – more than double the rate of population growth – and it’s still growing as farming, industry and domestic demand all increase.

The textile industry uses vast amounts of water throughout all processing operations.  Almost all dyes, specialty chemicals and finishing chemicals are applied to textiles in water baths.  Most fabric preparation steps, including desizing, scouring, and bleaching use water.  And each one of these steps must be followed by a thorough washing of the fabric to remove all chemicals used before moving on to the next step.  The water is usually returned to our ecosystem without treatment – meaning that the wastewater, which is returned to our streams, contains all of the process chemicals used during milling.  This pollutes the groundwater.  As the pollution increases, the first thing that happens is that the amount of useable water declines.  But the health of people depending on that water is also at risk, as is the health of the entire ecosystem.

With no controls in place to speak of to date, there are now 405 dead zones in our oceans.  Drinking water even in industrialized countries, with treatment in place, nevertheless yields a list of toxins when tested – many of them with no toxicological roadmap.  The textile industry is the #1 industrial polluter of fresh water on the planet – the 9 trillion liters of water used annually in textile processing is usually expelled into our rivers without treatment and is a major source of groundwater pollution.  Now that virtual or “embedded” water tracking is becoming necessary in evaluating products, people are beginning to understand when we say it takes 500 gallons of water to make the fabric to cover one sofa.  We want people to become aware that when they buy anything, and fabric especially, they reinforce the manufacturing processes used to produce it.  Just Google “Greenpeace and the textile industry” to find out what Greenpeace is doing to make people aware of this issue.

Over 8,000 chemicals are used in textile processing, some so hazardous that OSHA requires textile scraps be handled as hazardous waste.   The final product is, by weight, about 23% synthetic chemicals – often the same chemicals that are outlawed in other products.  The following is by no means an all-inclusive list of these chemicals:

  • Alkylphenolethoxylates (APEOs), which are endocrine disruptors;
    • o Endocrine disruptors are a wide range of chemicals which interfere with the body’s endocrine system to produce adverse developmental, reproductive, neurological and immune effects in both humans and wildlife; exposure us suspected to be associated with altered reproductive function in both males and females, increased incidence of breast cancer, abnormal growth patterns and neurodevelopmental delays in children.(2)
  • Pentachlorophenols (PCP)
    • o Long-term exposure to low levels can cause damage to the liver, kidneys, blood, and nervous system. Studies in animals also suggest that the endocrine system and immune system can also be damaged following long-term exposure to low levels of pentachlorophenol. All of these effects get worse as the level of exposure increases.(3)
  • Toluene and other aromatic amines
    • carcinogens (4)
  • Dichloromethane (DCM)
    • Exposure leads to decreased motor activity, impaired memory and other neurobehavioral deficits; brain and liver cancer.(5)
  • Formaldehyde
    • The National Toxicology Program named formaldehyde as a known human carcinogen in its 12th Report on Carcinogens.(6)
  • Phthalates –
    • Associated with a range of effects from liver and kidney diseases to developmental and reproductive effects, reduced fetal weight.(7)
  • Polybrominated diphenyl ethers (PBDE’s)
    • A growing body of research in laboratory animals has linked PBDE exposure to an array of adverse health effects including thyroid hormone disruption, permanent learning and memory impairment, behavioral changes, hearing deficits, delayed puberty onset, decreased sperm count, fetal malformations and, possibly, cancer.(8)
  • Perfluorooctane sulfonates (PFOS)
    • To date, associations have been found between PFOS or PFOA levels in the general population and reduced female fertility and sperm quality, reduced birth weight, attention deficit hyperactivity disorder (ADHD), increased total and non-HDL (bad) cholesterol levels, and changes in thyroid hormone levels.(9)
  • Heavy metals – cadmium, lead, antimony, mercury among others
    • Lead is a neurotoxin (affects the brain and cognitive development) and affects the reproductive system; mercury is a neurotoxin and possibly carcinogenic; cadmium damages the kidneys, bones and the International Agency for Research on Cancer has classified it as a human carcinogen; exposure to antimony can cause reproductive disorders and chromosome damage.

The textile industry uses huge quantities of fossil fuels  –  both to create energy directly needed to power the mills, produce heat and steam, and power air conditioners, as well as indirectly to create the many chemicals used in production.  In addition, the textile industry has one of the lowest efficiencies in energy utilization because it is largely antiquated.  For example, steam used in the textile manufacturing process is often generated in inefficient and polluting coal-fired boilers.  Based on estimated annual global textile production of 60 billion kilograms (KG) of fabric, the estimated energy needed to produce that fabric boggles the mind:  1,074 billion KWh of electricity (or 132 million metric tons of coal).  It takes 3886 MJ of energy to produce 25 yards of nylon fabric (about the amount needed to cover one sofa).  To put that into perspective, 1 gallon of gasoline equals 131 MJ of energy; driving a Lamborghini from New York to Washington D.C. uses approximately 2266 MJ of energy.(10)

Today’s textile industry is also one of the largest sources of greenhouse gasses on the planet: in the USA alone, it accounts for 5% of the country’s CO2 production annually; China’s textile sector alone would rank as the 24th– largest country in the world.(11)

We succeeded in producing the world’s first collection of organic fabrics that were gorgeous and green – and safe.    In 2007, those fabrics won “Best Merchandise” at Decorex (www.decorex.com).    In 2008, our collection was named one of the Top Green Products of 2008 by BuiltGreen/Environmental Building News. As BuiltGreen/EBN takes no advertising dollars, their extensive research is prized by the green building industry (www.buildinggreen.com).

We are a tiny company with an oversized mission.  We are challenged to be a triple bottom line company, and we want to make an outsized difference through education for change  – so that a sufficiently large number of consumers will know which questions to ask that will force change in an industry.  We believe that a sufficiently large number of people will respond to our message to force profound positive change: by demanding safe fabric, produced safely, our environment and our health will be improved.

The issues that distinguish us from other fabric distributors, in addition to offering fabrics whose green pedigree is second to none:

    1. We manage each step of the production process from fiber to finished fabric, unlike other companies, which buy mill product and choose only the color palette of the production run.    Those production process steps include fiber preparation, spinning, weaving, dyeing, printing and finishing; with many sub-steps such as sizing and de-sizing, bleaching, slashing, etc.
    2. We educate consumers and designers on the issues that are important to them – and to all of us. Our blog on the topic of sustainability in the textile industry has grown from about 2 hits a day to 2,000, and is our largest source of new customers.
    3. We are completely transparent in all aspects of our production and products.    We want our brand to be known not only as the “the greenest”, but for honesty and authenticity in all claims.  This alignment between our values, our claims and our products fuels our passion for the business.
    4. We are the only collection we know of which sells only “safe” fabrics.

We serve multiple communities, but we see ourselves as being especially important to two communities:  those who work to produce our fabric and those who use it, especially children and their parents.

    • By insisting on the use of safe chemicals exclusively, we improve the working conditions for textile workers.  And by insisting on water treatment, we mitigate the effects of even benign chemicals on the environment – and the workers’ homes and agricultural land.  Even salt, used in copious amounts in textile processing, will ruin farmland and destroy local flora and fauna if not neutralized before being returned to the local waters.
    • For those who use our fabric, chemicals retained in the finished fibers do not add to our “body burden “, which is especially important for children, part of our second special community.  A finished fabric is, by weight, approximately 23% synthetic chemicals. Those chemicals are not benign.  Textile processing routinely uses chemicals with known toxic profiles such as lead, mercury, formaldehyde, arsenic and benzene – and many other chemicals, many of which have never been tested for safety.

Another thing we’d like you to know about this business is the increasing number of people who contact us who have been harmed by fabric (of all things!) because we represent what they believe is an honest attempt at throwing light on the subject of fabric processing.   Many are individuals who suffer from what is now being called “Idiopathic Environmental Intolerance” or IEI (formerly called Multiple Chemical Sensitivity), who are looking for safe fabrics.  We’ve also been contacted on behalf of groups, for example,   flight attendants, who were given new uniforms in 2011, which caused allergic reactions in a large number of union members.

These incidences of fabric-induced reactions are on the rise.   As we become more aware of the factors that influence our health, such as we’re seeing currently with increased awareness of the effects of interior air quality, designers and others will begin to see their way to specifying “safe” fabrics  just as their code of ethics demands.(12)  We feel certain that the trajectory for such an important consumer product as fabric, which surrounds us most of every hour of the day, will mimic that of organic food.

We say our fabrics are luxurious – because luxury has become more about your state of mind than the size of your wallet. These days, people define luxury by such things as a long lunch with old friends, the good health to run a 5K, or waking up in the morning and doing exactly what you want all day long.  In the past luxury was often about things.  Today, we think it’s not so much about having as it is about being knowledgeable about what you’re buying – knowing that you’re buying the best and that it’s also good for the world.  It’s also about responsibility: it just doesn’t feel OK to buy unnecessary things when people are starving and the world is becoming overheated.  It’s about products being defined by how they make you feel –  “conscious consumption” – and giving you ways to find personal meaning and satisfaction.

10 reasons to make sure your sofa choices are upholstered with safely processed fabrics.

28 10 2013

If a fabric is identified as 100%  “cotton” – or even 100% “organic cotton”  —  it’s important to remember that processing the fiber, and then weaving it into fabric, is very chemically intense.  One-quarter of the total weight of the finished fabric is made up of synthetic chemicals, so it’s important to know that the chemicals used in your fabrics are safe! [1]

There have not been a lot of studies which show the effects that chemicals contained in a fabric have on humans as a result of using that fabric, perhaps because there are no interested parties other than universities and government entities.   But there are numerous studies which document the effects which the individual chemicals have on humans – perhaps because the textile industry is so fragmented that the few really large corporations with the resources to do this kind of research tend to finance research which supports  new products (such as DuPont’s PLA fibers or Teijin’s recycling efforts).  But there have been some, and we found the following:

  1. Formaldehyde is used often in finishing textiles to give the fabrics easy care properties (like wrinkle resistance, anti cling, stain resistance, etc.).  Formaldehyde resins are used on almost all cotton/poly sheet sets in the USA.
    1. Formaldehyde is a listed human carcinogen.  Besides being associated with watery eyes, burning sensations in the eyes and throat, nausea, difficulty in breathing, coughing, some pulmonary edema (fluid in the lungs), asthma attacks, chest tightness, headaches, and general fatigue, as well as well documented skin rashes, formaldehyde is associated with more severe health issues:  For example, it could cause nervous system damage by its known ability to react with and form cross-linking with proteins, DNA and unsaturated fatty acids.13 These same mechanisms could cause damage to virtually any cell in the body, since all cells contain these substances. Formaldehyde can react with the nerve protein (neuroamines) and nerve transmitters (e.g., catecholamines), which could impair normal nervous system function and cause endocrine disruption. [3]
      1. In January 2009, new blue uniforms issued to Transportation Security Administration officers gave them skin rashes, bloody noses, lightheadedness, red eyes, and swollen and cracked lips, according to the American Federation of Government Employees, the union representing the officers.
      2. In 2008, more than 600 people joined a class action suit against Victoria’s Secret, claiming horrific skin reactions (and permanent scarring for some) as a result of wearing Victoria Secret’s bras.   Lawsuits were filed in Florida and New York – after the lawyers found formaldehyde in the bras.
      3. Contact dermatitis is a well-known condition, and there are many websites which feature ways to get help.
      4. A study by The National Institute for Occupational Safety and Health found a link in textile workers between length of exposure to formaldehyde and leukemia deaths.[2]
    2. Dioxins:  Main uses of dioxin in relation to textiles is as a preservative for cotton and other fibers during sea transit,  and in cotton bleaching. It is also found in some dyestuffs.  Dioxin is known as one of the strongest poisons which man is able to produce. It causes cancer of the liver and lung, and interferes with the immune system, resulting in a predisposition to infectious diseases and embrional misgrowth.
      1. Studies have found dioxin leached from clothing  onto  the skin of participants:[3]  It was shown that these contaminants are transferred from textiles to human skin during wearing. They were also present in shower water and were washed out of textiles during washing. Extensive evidence was found indicating that contaminated textiles are a major source of chlorinated dioxins and furans in non-industrial sewage sludge, dry cleaning residues and house dust.
    3. Perfluorocarbons (PFC’s)  break down within the body and in the environment to PFOA, PFOS and similar chemicals. (Note: the chemistry here is quite dense; I’ve tried to differentiate between the groups. Please let me know if I’ve made a mistake!) They are the most persistent synthetic chemicals known to man. Once they are in the body, it takes decades to get them out – assuming you are exposed to no more. They are toxic in humans with health effects from increased chloesterol to stroke and cancer. Although little PFOA can be found in the finished product, the breakdown of the fluorotelomers used on paper products and fabric treatments might explain how more than 90% of all Americans have these hyper-persistent, toxic chemicals in their blood. A growing number of researchers believe that fabric-based, stain-resistant coatings, which are ubiquitous, may be the largest environmental source of this  controversial chemical family of PFCs.

PFC’s are used in stain resistant finishes/fabrics such as Scotchgard, GoreTex, Crypton, Crypton Green, GreenShield, Teflon:

  1. PFC’s cause developmental and other adverse effects in animals.[4]
  2. According to a study published in the Journal of the American Medical Association, the more exposure children have to PFC’s (perfluorinated compounds), the less likely they are to have a good immune response to vaccinations (click here to read the study).[5]

According to the U.S. Environmental Protection Agency, PFC’s:

  • Are very persistent in the environment.
  • Are found at very low levels both in the environment and in the blood of the U.S. population.
  • Remain in people for a very long time.
  • Cause developmental and other adverse effects in laboratory animals.

The levels of PFC’s globally are not going down – and in fact there are places (such as China) where the PFC level is going up. And as there is not a “no peeing” part of the pool, the exposure problem deserves international attention.

4. Tributylphosphate – or TBP – is used in the production of synthetic resins and as a flame-retarding plasticizer. It is also used as a primary plasticizer in the manufacture of plastics and as a pasting agent for pigment pastes used in printing. Because it is a strong wetting agent, it is used often in the textile industry.  In addition to being a known skin irritant (click here to see the MSDS with a warning that it causes eye and skin irritation), TBP also causes bladder cancer in rats. (2)

  1. Alaska Airlines flight attendants were given new uniforms in 2010; shortly thereafter many reported “dermal symptoms” (e.g., hives, rash, blisters, skin irritation), while some also referenced respiratory symptoms and eye irritation; some have more recently been diagnosed with abnormal thyroid function. The symptoms apparently occurred only while wearing the new uniforms. (To read the report filed with the Consumer Product Safety Commission by the Association of Flight Attendants, click here. )

The only fact which can be agreed upon between the union, the CPSC and the manufacturer is that some unknown percent of the fabric used to make the uniforms was “contaminated” with TBP, tributylphosphate, as reported by the manufacturer – but since not all the fabric was tested, it is unknown the final percentage of contaminated fabric.

5.  Acrylic fibers are made from acrolynitrile  (also called vinyl cyanide), which is a carcinogen (brain, lung and bowel cancers) and a mutagen, targeting the central nervous system. According to the Centers for Disease Control and Prevention, acrylonitrile enters our bodies through skin absorption, as well as inhalation and ingestion.  It is not easily recycled nor is it biodegradeable.

  1. Women who work in factories which produce acrylic fibers have seven times the rate of breast cancer as the normal population [6] – those working with nylon have double the risk.

6.  Chemicals used in textile processing which are associated with the immune system include formaldehyde, benzenes, toluene, phthalates. In 2007, The National Institutes of Health and the University of Washington released the findings of a 14 year study that demonstrates those who work with textiles were significantly more likely to die from an autoimmune disease than people who didn’t [7].

  1. Allergies and asthma are both thought to be associated with impaired immune systems.   Twice as many Americans (not just children) have asthma now as 20 yrs ago[8] and 10% of American children now have asthma.[9]
  2. As well as allergies and asthma, there are numerous other ‘chronic inflammatory diseases’ (CIDs) such as Type 1 diabetes and multiple sclerosis which seem to stem from impaired regulation of our immune systems.[10]

7.  Chemicals commonly used in textiles which contribute to developmental disorders (such as (ADD, ADHA, autism, Dyslexia): Bisphenol A, flame retardants, heavy metals (lead, mercury, cadmium), phthalates, PCB’s:

  1. Currently one of every six American children has a developmental disorder of some kind.[11]
  2. Bisphenol A  – used as a finish in the production of synthetic fibers: It mimics estrogens (is an endocrine disruptor) and can cause infertility and cancer.[12] 

8.  PCB’s :  used in flame retardants on fabrics; they are neurotoxins, endocrine disruptors and carcinogenic

  1. The Environmental Protection Agency (EPA) commissioned psychologists to study children whose mothers were exposed to PCB’s during pregnancy. The researchers found  that the more PCBs  found in the mother’s cord blood, the worse the child did on tests for things such as short-term memory. By age eleven, the most highly exposed kids had an average IQ deficit of 6.2 [13].

9.  Cancer – chemicals used in textile processing which are linked to cancer include formaldehyde, lead, cadmium, pesticides, benzene, vinyl chloride – as well as pesticides on crops: 

  1. all childhood cancers have grown at about 1% per year for the past two decades[14]
  2.  brain cancer in children increased nearly 40% from 1973 to 1994[15]
  3. the environmental attributable fraction of childhood cancer can be between 5% and 90%, depending on the type of cancer[16]

10.  Lead – used in the textile industry in a variety of ways and as a component in dyestuffs –  is a neurotoxin – it affects the human brain and cognitive development, as well as the reproductive system. Some of the kinds of neurological damage  caused by lead are not reversible.        Specifically, it affects reading and reasoning abilities in  children, and is also linked to hearing loss, speech delay, balance difficulties and violent tendencies.[17]     Children are uniquely susceptible to lead exposure over time,  and  neural damage occurring during the period from 1 to 3 years of age is not likely to be reversible.  It’s also important to be aware  that lead available from tested products would not be the only source of  exposure in a child’s environment.        Lead is used in the textile industry in a variety of ways and under a variety of names:

    1. Lead acetate:                        dyeing of textiles
    2. Lead  chloride                      preparation of lead salts
    3. Lead molybdate                   pigments used in dyestuffs
    4. Lead nitrate                         mordant in dyeing; oxidizer in dyeing(4)

Studies have shown that if children are exposed to lead, either in the womb or in early childhood, their brains are likely to be smaller.[18]

Lead is a uniquely cumulative poison: the daily intake of lead is not as important a determinant of ultimate harm as is the duration of exposure and the total lead ingested over time.

Fabric and your carbon footprint

3 10 2013

In considering fabric for your sofa, let’s be altruistic and look at the impact textile production has on global climate change.  (I only use the term altruistic  because many of us don’t equate climate change with our own lives, though there have been several interesting studies of just how the changes will impact us directly, like the one in USA Today that explains that wet regions will be wetter, causing flash flooding;  dry regions will get drier, resulting in drought. And  …  a heat wave that used to occur once every 100 years now happens every five years (1)).

Although most of the current focus on lightening our carbon footprint revolves around transportation and heating issues, the modest little fabric all around you turns out to be from an industry with a gigantic carbon footprint. The textile industry, according to the U.S. Energy Information Administration, is the 5th largest contributor to CO2 emissions in the United States, after primary metals, nonmetallic mineral products, petroleum and chemicals.[2]  And the US textile industry is small potatoes when compared with some other countries I could mention.  Last week we explained that a typical “quality” sofa  uses about 20 yards of decorative fabric, plus 20 yds of lining fabric, 15 yds of burlap and 10 yds of muslin, for a total of 65 yards of fabric – in one sofa.

The textile industry is huge, and it is a huge producer of greenhouse gasses.  Today’s textile industry is one of the largest sources of greenhouse gasses (GHG’s) on Earth, due to its huge size.[3] In 2008,  annual global textile production was estimated at  60 billion kilograms (KG) of fabric.  The estimated energy and water needed to produce that amount of fabric boggles the mind:

  • 1,074 billion kWh of  electricity  or 132 million metric tons of coal and
  • between 6 – 9  trillion liters of water[4]

Fabrics are the elephant in the room.  They’re all around us  but no one is thinking about them.  We simply overlook fabrics, maybe because they are almost always used as a component in a final product that seems rather innocuous:  sheets, blankets, sofas, curtains, and of course clothing.  Textiles, including clothing,  accounted for about one ton of the 19.8 tons of total CO2 emissions produced by each person in the U.S. in 2006. [5] By contrast, a person in Haiti produced a total of only 0.21 tons of total carbon emissions in 2006.[6]

Your textile choices do make a difference, so it’s vitally important to look beyond thread counts, color and abrasion results.

How do you evaluate the carbon footprint in any fabric?  Look at the “embodied energy’ in the fabric – that is, all of the energy used at each step of the process needed to create that fabric.   Not an easy thing to do!  To estimate the embodied energy in any fabric it’s necessary to add the energy required in two separate fabric production steps:

(1)  Find out what the fabric is made from, because the type of fiber tells you a lot about the energy needed to make the fibers used in the yarn.  The carbon footprint of various fibers varies a lot, so start with the energy required to produce the fiber.

(2) Next, add the energy used to weave those yarns into fabric.  Once any material becomes a “yarn” or “filament”, the amount of energy and conversion process to weave that yarn into a textile is pretty consistent, whether the yarn is wool, cotton,  or synthetic.[7]

Let’s look at #1 first: the energy needed to make the fibers and create the yarn. For ease of comparison we’ll divide the fiber types into “natural” (from plants, animals and less commonly, minerals) and “synthetic” (man made).

For natural fibers you must look at field preparation, planting and field operations (mechanized irrigation, weed control, pest control and fertilizers (manure vs. synthetic chemicals)), harvesting and yields.  Synthetic fertilizer use is a major component of the high cost of conventional agriculture:  making just one ton of nitrogen fertilizer emits nearly 7 tons of CO2 equivalent greenhouse gases.

For synthetics, a crucial fact is that the fibers are made from fossil fuels.   Very high amounts of energy are used in extracting the oil from the ground as well as in the production of the polymers.

A study done by the Stockholm Environment Institute on behalf of the BioRegional Development Group  concludes that the energy used (and therefore the CO2 emitted) to create 1 ton of spun fiber is much higher for synthetics than for hemp or cotton:

KG of CO2 emissions per ton of spun   fiber:
crop cultivation fiber production TOTAL
polyester USA 0.00 9.52 9.52
cotton, conventional, USA 4.20 1.70 5.90
hemp, conventional 1.90 2.15 4.05
cotton, organic, India 2.00 1.80 3.80

The table above only gives results for polyester; other synthetics have more of an impact:  acrylic is 30% more energy intensive in its production than polyester [8] and nylon is even higher than that.

Not only is the quantity of GHG emissions of concern regarding synthetics, so too are the kinds of gasses produced during production of synthetic fibers.  Nylon, for example, creates emissions of N2O, which is 300 times more damaging than CO2 [9] and which, because of its long life (120 years) can reach the upper atmosphere and deplete the layer of stratospheric ozone, which is an important filter of UV radiation.  In fact, during the 1990s, N2O emissions from a single nylon plant in the UK were thought to have a global warming impact equivalent to more than 3% of the UK’s entire CO2 emissions.[10] A study done for the New Zealand Merino Wool Association shows how much less total energy is required for the production of natural fibers than synthetics:

Natural fibers, in addition to having a smaller carbon footprint in the production of the spun fiber, have many additional  benefits:

  1. being able to be degraded by micro-organisms and composted (improving soil structure); in  this way the fixed CO2 in the fiber will be released and the cycle closed.   Synthetics do not decompose: in landfills they release  heavy metals and other additives into soil and groundwater.       Recycling requires costly separation, while incineration produces  pollutants – in the case of high density polyethylene, 3 tons of CO2 emissions are produced for ever 1 ton of material burnt.[11] Left in the environment, synthetic fibers contribute, for example, to the estimated 640,000 tons of abandoned  fishing nets in the world’s oceans.
  2. sequestering  carbon.  Sequestering carbon is the process through which CO2 from the atmosphere is absorbed by plants through photosynthesis and stored as carbon in biomass (leaves, stems, branches, roots, etc.) and soils.       Jute, for example, absorbs 2.4 tons of carbon per ton of dry fiber.[12]

Substituting organic fibers for conventionally grown fibers is not just a little better – but lots better in all respects:

  • uses less energy for production,
  • emits fewer greenhouse gases
  • and supports organic farming (which has myriad environmental, social and health benefits).

A study published by Innovations Agronomiques (2009) found that 43% less GHG are emitted per unit area under organic agriculture than under conventional agriculture.[13] A study done by Dr. David Pimentel of Cornell University found that organic farming systems used just 63% of the energy required by conventional farming systems, largely because of the massive amounts of energy requirements needed to synthesize nitrogen fertilizers. Further it was found in controlled long term trials that organic farming adds between 100-400kg of carbon per hectare to the soil each year, compared to non-organic farming.  When this stored carbon is included in the carbon footprint, it reduces the total GHG even further.[14] The key lies in the handling of organic matter (OM): because soil organic matter is primarily carbon, increases in soil OM levels will be directly correlated with carbon sequestration. While conventional farming typically depletes soil OM, organic farming builds it through the use of composted animal manures and cover crops.

Taking it one step further beyond the energy inputs we’re looking at, which help to mitigate climate change, organic farming helps to ensure other environmental and social goals:

  • eliminates the use of synthetic fertilizers, pesticides and genetically modified organisims      (GMOs) which is  an improvement in human health and agrobiodiversity
  • conserves water  (making the soil more friable so rainwater is absorbed better – lessening      irrigation requirements and erosion)
  • ensures sustained  biodiversity
  • and compared to forests, agricultural soils may be a more secure sink for atmospheric      carbon, since they are not vulnerable to logging and wildfire.

Organic agriculture is an undervalued and underestimated climate change tool that could be one of the most powerful strategies in the fight against global warming, according to Paul Hepperly, Rodale Institute Research Manager. The Rodale Institute Farming Systems Trial (FST) soil carbon data (which covers 30 years)  provides convincing evidence that improved global terrestrial stewardship–specifically including regenerative organic agricultural practices–can be the most effective currently available strategy for mitigating CO2 emissions.

At the fiber level it is clear that synthetics have a much bigger footprint than does any natural fiber, including wool or conventionally produced cotton.   So in terms of the carbon footprint at the fiber level, any natural fiber beats any synthetic – at this point in time.   Best of all is an organic natural fiber.

And next let’s look at #2, the energy needed to weave those yarns into fabric.

There is no dramatic difference in the amount of energy needed to weave fibers into fabric depending on fiber type.[15] The processing is generally the same whether the fiber is nylon, cotton, hemp, wool or polyester:   thermal energy required per meter of cloth is 4,500-5,500 Kcal and electrical energy required per meter of cloth is 0.45-0.55 kwh. [16] This translates into huge quantities of fossil fuels  –  both to create energy directly needed to power the mills, produce heat and steam, and power air conditioners, as well as indirectly to create the many chemicals used in production.  In addition, the textile industry has one of the lowest efficiencies in energy utilization because it is largely antiquated.

(7)    Many discussions of energy used to produce fabrics or final products made from fabrics (such as clothing) take the “use” phase of the article into consideration when evaluating the carbon footprint.  The argument goes that laundering the blouse (or whatever) adds considerably to the final energy tally for natural fibers, while synthetics don’t need as much water to wash nor as many launderings.  We do not take this component into consideration because

  1. it applies only to clothing; even sheets aren’t washed as often as clothing while upholstery is seldom cleaned.
  2. is biodegradeable detergent used?
  3. Is the washing machine used a new low water machine?  Is the water treated by a municipal facility?
  4. Synthetics begin to smell if not treated with antimicrobials, raising the energy score.

Indeed, it’s important to evaluate the sponsors of any published studies, because the studies done which evaluate the energy used to manufacture fabrics are often sponsored by organizations which might have an interest in the outcome.  Additionally, the data varies quite a bit so we have adopted the values which seem to be agreed upon by most studies.

Global Organic Textile Standard

2 09 2011

In the 1980’s, producers of eco-friendly textiles generally worked under the umbrella of  organic food associations.  However, they found that the food association was impractical for textile producers because  although the growing and harvesting of food and fiber crops were similar, the processing of fibers in preparation to make fabric varied widely.  The organic food associations were concerned primarily with food related issues.   In addition, organic fabrics and fashion was being shown in specialized stores rather than in organic food markets.

In 2002, at the Intercot Conference in Dusseldorf, Germany, a workshop with representatives of organic cotton producers, the textile industry, consumers, standard organizations and certifiers discussed the need for a harmonized and world-wide recognized organic textile standard.  The many different standards, they felt, was causing confusion and acting as a obstacle to international exchange and recognition of organic fabrics.  As a result of this workshop, the  “International Working Group on Global Organic Textile Standard“ (IWG) was founded, with an aim to work on the codification of various regional approaches and to develop a set of global standards.  Members of this group included Internationale Verband der Naturtextilwirtschaft e. V.“ (IVN),  the  Organic Trade Association (United States), the Soil Association (England)  and Japan Organic Cotton Association  (Japan).

In 2006, their work was published as the Global Organic Textile Standard (GOTS) , which has since evolved into the leading set of criteria in the field of organic textile processing.  A main achievement of this group was the ability to compromise and to find even consensus for points that were considered to be ‘non-negotiable’.   Not all standard organizations that participated the process ended up with signing the agreement of the Working Group.

From the GOTS website:  “Since its introduction in 2006 by the International Working Group on Global Organic Textile Standard, the GOTS has gained universal recognition, led to abolishment of numerous previous similar standards of limited application and has become – with more than 2750 certified textile processing, manufacturing and trading operators in more than 50 countries and an abundance of certified products – the leading standard for the processing of textile goods using organic fibers, including environmentally oriented technical as well as social criteria.”  This is a major accomplishment, especially given the global nature of the textile supply chain.

Beside the technical requirements a certifier has to meet to become approved by the IWG for GOTS certification, it is also a prerequisite that he discontinues use of any other certification. This measure was chosen to support the goal of a harmonized Global Standard and related certification system that allows certified suppliers to export their organic textiles with one certificate recognized in all relevant sales markets in order to strengthen the awareness and market for organic textiles.

The following standards have become completely harmonized with GOTS:

  • North American Fiber Standard – Organic Trade Association (USA)
  • Guidelines ‘Naturtextil IVN Zertifiziert’ – International Association Natural Textile Industry (Germany)
  • Standards for Processing and Manufacture of Organic Textiles – Soil Association (England)
  • EKO Sustainable Textile Standard – Control Union Certifications (formerly SKAL)
  • Standards for Organic Textiles – Ecocert (France)
  • Organic Textile Standard – ICEA (Italy)
  • Standards for Organic Textiles – ETKO (Turkey)
  • Organic Fiber Standards – Oregon Tilth (USA)
  • Standards for Processing of Organic Textile Products – OIA (Argentina)

One member of the IWG offers beside GOTS as their basic standard one further standard for certification that complies with GOTS but contains some additional requirements:

  • Guidelines ‘Naturtextil IVN Zertifiziert BEST’ – International Association Natural Textile Industry (Germany)

GOTS aims to define a universal standard for organic fabrics—from harvesting the raw materials, through environmentally and socially responsible manufacturing, to labeling—in order to provide credible assurance to consumers. Standards apply to fiber products, yarns, fabrics and clothes and cover the production, processing, manufacturing, packaging, labeling, exportation, importation and distribution of all natural fiber products.   GOTS provides a continuous quality control and certification system from field to shelf.  A GOTS certified fabric is therefore much more than just a textile which is made from organic fibers.

Why is this a big deal?  As we’ve said before, it’s like taking organic apples, and cooking them with Red Dye #2, preservatives, emulsifiers, and stabilizers –  you can’t call the finished product organic applesauce.  Same is true with fabrics, which contain as much as 27% (by weight) synthetic chemicals.

And in today’s world, with the complex supply chain that multinational companies like Wal-Mart, Nordstrom and Levi’s use, this is a very big deal.   As companies attempt to get a handle on their suppliers and maintain quality control, the list of universally understood environmental criteria in GOTS  is coming in handy. While consumers probably won’t see a GOTS tag on conventional cotton jeans, some companies are asking suppliers to use only GOTS-certified dyes and chemicals on conventional cotton clothing.  In fact, the companies mentioned above, along with Banana Republic, H&M and Target are just some of the companies that plan to use GOTS certification for their organic products.

The GOTS standard includes:

  • Harvesting criteria which requires the use of from 70% to 95% organic fiber.
    • As the GOTS website explains, “As it is to date technically nearly impossible to produce any textiles in an industrial way without the use of chemical inputs, the approach is to define criteria for low impact and low residual natural and synthetic chemical inputs.   So in addition to requiring that   all inputs have to meet basic requirements on toxicity and biodegradability GOTS also  prohibits entire classes of chemicals, rather than calling out specific prohibited chemicals.  What that means is that instead of prohibiting, for example lead and cadmium (and therefore allowing other heavy metals by default), GOTS prohibits ALL heavy metals.  Here’s the Version 3.0 list:
Aromatic solvents Prohibited
Chlorophenols (such as TeCP, PCP) Prohibited
Complexing agents and surfactants Prohibited are: All APEOS, EDTA, DTPA, NTA, LAS, a-MES
Fluorocarbons Prohibited (i.e., PFOS, PFOA)
Formaldehyde and short-chain aldehydes Prohibited
GMO’s Prohibited
Halogenated solvents Prohibited
Heavy Metals Prohibited
Inputs containing functional nanoparticles Prohibited
Inputs with halogen containing compounds Prohibited
Organotin compounds Prohibited
Plasticizers (i.e., Phthalates, Bisphenol A and all others with endocrine disrupting potential) Prohibited
Quaternary ammonium compounds Prohibited: DTDMAC, DSDMAC and DHTDM
  • Environmental manufacturing practices, with a written environmental policy, must be in place.
  • Environmentally safe processing requirements, which includes wastewater treatment internally before discharge to surface waters, must be in place.  This pertains to pH and  temperature as well as to biological and chemical residues in the water.
  • Environmentally sound packaging requirements are in place; PVC in packaging is prohibited, paper must be post-consumer recycled or certified according to FSC or PEFC.
  • Labor practices are interpreted in accordance with the International Labor Organization (ILO – no forced, bonded, or slave labor; workers have the right to join or form trade unions and to bargain collectively; working conditions are safe and hygienic; there must be no new recruitment of child labor (and for those companies where children are found to be working, provisions must be made to enable him to attend and remain in quality education until no longer a child);  wages paid must meet, at a minimum, national legal standards or industry benchmarks, whichever is higher; working hours are not excessive and inhumane treatment is prohibited.
  • GOTS has a dual system of quality assurance consisting of on-side annual inspection (including possible unannounced inspections based on risk assessment of the operations) and residue testing.
  • There are requirements surrounding exportation, importation and distribution of all natural fibers.

In June, 2011, The Global Organic Textile Standard launched an open comment period on it’s first revision draft of the new GOTS version 3.0.  Following this announcement, IFOAM collected comments from its members and related stakeholders in order to shape the position of the movement towards the Global Organic Textile Standard.

A total of 36 persons and/or organizations sent their comments to IFOAM.  Two important issues were raised:  90% of the respondents were against the use of nanotechnologies in organic textiles (5% abstention, 5% in favor),  and 86 % were in principle against the use of synthetic chemicals in textiles labeled as organic (3% abstention, 11% in favor). Based on the feedback provided, IFOAM submitted detailed comments to GOTS and proposed:

  • to further restrict the use of synthetic substances, possibly switching to a positive list of allowed substances, instead of a list of forbidden ones.
  • to add requirements to ban the deliberate use of nano-technologies in the textile processing.

GOTS is a positive ethical choice among both consumers and producers and is the most comprehensive in terms of addressing environmental issues.  Although it is difficult to obtain, it can lead to important strategic business benefits.

However, the GOTS certification applies to only natural fibers, so it cannot be applied to polyester or other synthetic fibers, which are by far the most popular fiber choice in the U.S. today.  In addition, it does not directly address the carbon footprint of an organization or its production practices.  (Please note: the choice of a fabric made of organically raised natural fibers has been shown to have a much lower carbon impact than any fabric made of synthetic fibers.  We touched on that in our some of our blog posts; click here and here to read them.)
