How to buy a sofa: part 4: so which fabric will it be?

16 09 2011

So for the past two weeks we’ve discussed the differences between synthetic and natural fibers.  But there’s more to consider than just the fiber content of the fabric you buy.  There is the question of whether a natural fiber is organically grown, and what kind of processing is used to create the fabric.

First, by substituting organic fibers for conventionally grown fibers you are supporting organic agriculture, which has myriad environmental, social and health benefits.  Not only does organic farming take far less energy than conventional farming (largely because it does not use oil based fertilizers) [1] , which helps to mitigate climate change, but it also:

  • eliminates the use of synthetic fertilizers, pesticides and genetically modified organisms (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 production has a strong social element and includes many Fair Trade and ethical production principles.  As such it can be seen as more than a set of agricultural practices, but also as a tool for social change.[2]  For example, one of the original goals of the organic movement was to create specialty products for small farmers who could receive a premium for their products and thus be able to compete with large commercial farms.

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)  shows conclusively that improved global terrestrial stewardship–specifically including regenerative organic agricultural practices–can be the most effective currently available strategy for mitigating CO2 emissions. [3]

But if you start with organic natural fibers (a great choice!)  but process those fibers conventionally, then you end up with a fabric that is far from safe.  Think about making applesauce:  if you start with organic apples, then add Red Dye #2, preservatives, emulsifiers, stablizers and who knows what else – do you end up with organic applesauce?  The US Department of Agriculture would not let you sell that mixture as organic applesauce, but there is no protection for consumers when buying fabric.  And the same issues apply, because over 2000 chemicals are used routinely in textile processing.(4)  Many of the chemicals used in textile processing have unknown toxicity, and many others are known to be harmful to humans (such as formaldehyde, lead, mercury, bisphenol A and other phthalates,  benzenes and others).   In fact, one yard of fabric made with organic cotton fiber  is about 25% by weight synthetic chemicals – many of which are proven toxic to humans. (5)

I know you’re saying that you don’t eat those fabrics, so what’s the danger?  Actually, your body is busy ingesting the chemicals, which are evaporating (so we breathe them in), or through skin absorption (after all, the skin is the largest organ of the body).  Add to that the fact that each time you brush against the fabric, microscopic pieces of the fabric abrade and fly into the air – so we can breathe them in.  Or they fall into the dust in our homes, where pets and crawling babies breathe them in.

Should that be a concern?  Well, there is hardly any evidence of the effects of textiles themselves on individuals, but in the US, OSHA does care about workers, so most of the studies have been done on workers in the textile industry.  Greenpeace also did a study on specific items manufactured by Disney, but I would guess the results pertain all across the spectrum:

  • Autoimmune diseases (such as IBD, diabetes, rheumatoid arthritis,  for example, and linked to many of the chemicals used in textile processing) are reaching epidemic rates,  and a 14 year study published by the University of Washington and the National Institutes of Health found that people who work with textiles (among other industries) are more likely to die of an autoimmune disease than people who don’t (6);
  • We know formaldehyde is bad for us, but in fabric?  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.[7]  Note: most cotton/poly sheet sets in the U.S. are treated with a formaldehyde resin.
  • Women who work in textile factories with acrylic fibers have seven times the risk of developing breast cancer than does the normal population.[8]
  • A study in France revealed a correlation between the presence of cancer of the pharynx and occupation in the textile industry.(9)
  • A high degree of colorectal cancer, thyroid cancer, testicular cancer and nasal cancer has been found among textile workers, and a relationship between non-Hodgkin’s lymphoma and working in the textile industry was observed.(10)

And consider this:

  • The Mt. Sinai Children’s Environmental Health Center published a list of the top 10 chemicals they believe are linked to autism – and of the 10, 6 are used in textile processing and 2 are pesticides. (11)
  • Phthalates are so toxic that they have been banned in the European Union since 2005. They have recently been banned in the State of California in children’s toys.   They are ubiquitous –  and are also found  in most  textile inks.[12]  So parents careful not to bring toxic toys into their homes for  can be  nevertheless  unknowingly putting their kids to sleep on cute printed sheets full of phthalates.

Though some argue that we’re less prepared because we’re confronting fewer natural pathogens, it’s also true that we’re  encountering an endless barrage of artificial pathogens that are taxing our systems to the maximum.  And our children are the pawns in this great experiment.

Are these rates of disease and the corresponding rise in the use of industrial chemicals a coincidence? Are our increased rates of disease due to better diagnosis?   Some argue that we’re less prepared because we’re confronting fewer natural pathogens.  All plausible.   But if you think they are the main culprits, your opinion is not shared by a goodly number of scientists, who believe that this endless barrage of artificial pathogens that is taxing our systems to the maximum  has replaced bacteria and viruses as the major cause of human illness.  We don’t have to debate which source is primary; especially because, with the rise of super bugs, it’s a silly debate. The point remains that industrial pollution is a cause of human illness – and it is a cause we can take concrete actions to stem.

Textiles are the elephant in the room – the industry is global, relatively low tech, and decentralized –  certainly not the darling of venture capatalists who look for the next big thing.  So not many research dollars are going into new ways of producing fabrics.    Most of the time people are looking for the lowest price fabric for their projects or products – so the industry is on a race to cut costs in any way possible:   in 2007, the Wall Street Journal’s Jane Spencer detailed the pollution caused by Chinese textile industries who were being pushing by their multinational clients to cut costs, resulting in untreated effluent discharge (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.

While greenbuilding proponents wrestle and argue over the embodied energy of concrete vs. steel, the REAL culprit is chemically-produced, chemical-laden textile production. Wake up designers! This is very powerful information right here, right now! Have the courage to copy this post and distribute to every one of your fabric suppliers and ask them to do something about their non-organically produced textile selections. In the meantime, simply begin diverting your textile business to O Ecotextiles; they deserve our support!
