Give our retail website, Two Sisters Ecotextiles, a look and let us know what you think.

We are pondering about whether to sell polyester fabrics – largely because people are insisting on it. And there is a lot of polyester being produced:

But, when (or if) we sell polyester fabric or blends, we have determined that the fabric must be GRS Gold level certified polyester, because:

1. GRS is to synthetics as GOTS is to natural fibers.  It is our assurance:
   1. that there is water treatment in place,
   2. that no toxic additives are used as process chemicals, and no finishes (such as fire retardants or stain repellants) are added to the fabric,
   3. and that workers have basic rights.
2. GRS provides verified support for the amount of recycled content in a yarn. It provides a track and trace certification system that ensures that the claim a fabric is made from recycled polyester can be officially backed up. Today, the supply chains for recycled polyester are not transparent, and if we are told that the resin chips we’re using to spin fibers are made from bottles – or from industrial scrap or old fleece jackets  – we have no way to verify that.  Once the polymers are at the melt stage, it’s impossible to tell where they came from.  So the yarn/fabric could be virgin polyester or it could be recycled.   Many so called “recycled” polyester yarns may not really be from recycled sources at all because – you guessed it! – the  process of recycling is much more expensive than using virgin polyester.  Unfortunately not all companies are willing to pay the price to offer a real green product, but they sure do want to take advantage of the perception of green.   So when you see a label that says a fabric is made from 50% polyester and 50% recycled polyester – well, (until now) there was absolutely no way to tell if that was true. In addition,

The Global Recycle Standard (GRS), originated by Control Union and now administered by Textile Exchange (formerly Organic Exchange), is intended to establish independently verified claims as to the amount of recycled content in a yarn, with the important added dimension of prohibiting certain chemicals, requiring water treatment and upholding workers rights, holding the weaver to standards similar to those found in the Global Organic Textile Standard:

• Companies must keep full records of the use of chemicals, energy, water consumption and waste water treatment including the disposal of sludge;
• All prohibitied chemicals listed in GOTS are also prohibited in the GRS;
• All wastewater must be treated for pH, temperature, COD and BOD before disposal (It’s widely thought that water use needed to recycle polyester is low, but who’s looking to see that this is true?  The weaving, however, uses the same amount of water (about 500 gallons to produce 25 yards of upholstery weight fabric) – so the wastewater is probably expelled without treatment, adding to our pollution burden)
• There is an extensive section related to worker’s rights.

Polyester is much (much, much, much!) cheaper than natural fibers and it wears like iron – so you can keep your sofa looking good for 30 years. The real question is, will you actually keep that sofa for 30 years?

There is still a problem with the production of synthetics. Burgeoning evidence about the disastrous consequences of using plastic in our environment continues to mount. A new compilation of peer reviewed articles, representing over 60 scientists from around the world, aims to assess the impact of plastics on the environment and human health [1] But synthetics do not decompose: in landfills they release heavy metals, including antimony, and other additives into soil and groundwater. If they are burned for energy, the chemicals are released into the air.

Also please keep in mind, that, if you choose a synthetic, then you bypass the benefits you’d get from supporting organic agriculture, which may be one of our most potent weapons in fighting climate change, because:

1. Organic agriculture acts as a carbon sink: new research has shown that what is IN the soil itself (microbes and other soil organisms in healthy soil) is more important in sequestering carbon that what grows ON the soil. And compared to forests, agricultural soils may be a more secure sink for atmospheric carbon, since they are not vulnerable to logging and wildfire. The Rodale Institute Farming Systems Trial (FST) soil carbon data (which covers 30 years) demonstrates that improved global terrestrial stewardship–specifically including regenerative organic agricultural practices–can be the most effective currently available strategy for mitigating CO2 emissions.
2. It eliminates the use of synthetic fertilizers, pesticides and genetically modified organisms (GMOs) which is an improvement in human health and agrobiodiversity
3. It conserves water (making the soil more friable so rainwater is absorbed better – lessening irrigation requirements and erosion)
4. It ensures sustained biodiversity

We’re not great fans of synthetics: Polyester is made from crude oil, and is the terminal product in a chain of very reactive and toxic precursors.   The manufacturing process requires workers and our environment to be exposed to some or all of the chemicals produced during the manufacturing process. There is no doubt that the manufacture of polyester is an environmental and public health burden that we would be better off without.

But there is a great quantity of existing polyester on this Earth, and there is only so much farmland that is available for cotton and other fiber crops, even though we have enough land to grow all the food and fiber we like, at least in theory.[2]

The biggest drawback to polyester production is that it requires a lot of energy, which means burning fuel for power and contributing to climate change. But to put that in perspective, Linda Greer, director of the health program at the Natural Resources Defense Council, says you actually release more carbon dioxide burning a gallon of gas than producing a polyester shirt.

However factories where polyester is produced which do not have end-of-pipe wastewater treatment systems release antimony along with a host of other potentially dangerous substances like cobalt, manganese salts, sodium bromide, and titanium dioxide into the environment.

In theory, cotton is biodegradable and polyester is not. But the thing is, the way we dispose of clothing makes that irrelevant. For cotton clothes to break down, they have to be composted, which doesn’t happen in a landfill.

The bottom line is that while the rise of polyester is not good news for the planet, a big increase in cotton production wouldn’t be any better, according to many sources: Both fabrics are created in huge factory plants, both go trough multiple chemical processes to make the final product, and both will be shipped around the globe.         (https://www.sewingpartsonline.com/blog/411-cotton-vs-polyester-pros-cons/)

But we keep returning to one point: there are already polyester bottles in existence. World demand for polyester in 2014 was a bit more than 46 million tons.[3] Only a small percentage of that is used for bottles, but that’s still a lot of bottles – in the United States, more than 42 billion bottles of water (only water!) were produced in 2010.[4] Doesn’t it make sense to re-use some of these bottles?

Mulling over the possibilities. Let us know how you feel.
