More about fabric choices for your sofa.

25 06 2015

Our previous blog post we talked about fabric – how to determine the quality of the fabric you’re considering for your new sofa.  But the most important consideration merits a blog all its own, and that is the safety of the fabrics you’ve chosen.  We define “safe” as a fabric that has been processed with none of the many chemicals known to harm human health – and in a perfect world we’d  throw in water treatment and human rights/labor issues too.

It’s a great idea to start with organic fibers, if you can.  By substituting organic natural 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 even 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, stabilizers 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.  There is no similar protection for consumers when buying fabric, even though 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] and are outlawed in other products.

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:

  • Autoimmune diseases (such as IBD, diabetes, rheumatoid arthritis, for example, which are 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 which produce 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 used on fiber crops. [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.

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 confronting fewer natural pathogens. All plausible.  But 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. And if you think artificial  pathogens  are  not 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 max 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 capitalists 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].

You can begin to protect yourself by looking for fabrics that have third party certifications:  either Oeko-Tex or The Global Organic Textile Standard (GOTS), which we believe is the gold standard in textiles because though Oeko-Tex assures you of a safe fabric and while GOTS confirms the same assurance, GOTS  also requires water treatment (important because the textile industry is the #1 industrial polluter of water on the planet (14) – and in this era of water shortages we have to start paying attention to our water resources) and prohibits child or slave labor (sadly still an issue) and makes sure workers have safe conditions to work in and are paid fair wages.

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.

Thank you for your textile posting on the chemicals used in the finishing processes of cloth. As I commented on your last posting re upholstery fabrics, this is a very timely and correct follow-up on textiles in general. One thing you overlooked in the way in which humans are exposed to these chemical is through inhalation from a steam iron. I am a quiltmaker, have been one since the early 1960’s. During that decade, formaldehyde in cloth was far less regulated as it became once the government set a standard ruling on the amount of formaldehyde allowed in textiles…still, I’m sure well above a safe limit still. During the 1970’s when I was teaching quilting in the city of Toronto, 100% cotton disappeared off the marketplace and cotton/polyester broadcloth took its place. Unknowingly, because I was teaching quilting, had formed the 2nd quilt guild in Canada and made many visual aids, I was standing over my hot steam iron inhaling the fumes from the cotton/poly cloth. All you have to do is place a hot steam iron on synthetic cloth to understand what I, along with another quilt teacher, were both exposed to. Gradual medical issues appeared, reactions to various things, unexplained, a final push over the edge some years later when I reacted badly to an anaesthetic from which I did not recover well and this led me into a journey of discovery of what textiles are really all about. I contacted the late Jeffery Gutcheon, who was a quilt textile converter at the time, asking about the chemicals in cloth and his response was: “cloth is one big chemical bath from beginning to end”. Think of the clothing we wear, the home decorative items such as upholstered furniture, there are endless ways in which we become sensitized to the chemicals in cloth. And one wonders why there is so much cancer about.
