On Fiber, Research, and the Environment

Perhaps you remember this commercial from a few years ago? I have very mixed feelings about it
...and yet I've posted it anyway. In a certain odd way it's a good introduction to this post.

Some readers may recall that earlier this summer I was designing some new fabrics using a new (to me) yarn. I thought the new fabric would be a wonderful addition to the color-grown cotton sweater knits and the reclaimed fabric panels I currently have in the shop. The colors were gorgeous, the yarn soft, and 70% of the fiber was recycled cotton. Thirty percent was polyester, which made the recycled cotton strong and a better knitting yarn.

Then I read about a research project conducted by a team of graduate students at University of California Santa Barbara's Bren School of Environmental Science & Management for their client Patagonia, the outdoor apparel company. Very briefly, for those unable to read project findings right now, the research team studied the microfiber and microplastic pollution in our oceans. This pollution begins in our washing machines after synthetic fabrics are laundered. These very tiny particles eventually reach the ocean, are consumed by fish, and end up in our food chain. The research group reviewed previous studies and conducted their own experiment. "To quantify microfiber shedding from washing synthetic jackets, [the researchers] conducted a series of wash experiments" using high-end (Patagonia) and budget synthetic fleece jackets. You can download the full 105-page report, a four-page summary of the report, and an infographic, if you scroll to the bottom of this page. Two interesting findings are that "top-load washing machine trials had 5.3 times the microfiber shedding of the front-load machine trials and... aging of jackets increased the mass of fibers shed by 1.8 times."

It turns out that a very good solution to this problem may come from research into the way textiles are laundered and the way in which textiles are made. Check out the Benign by Design and this presentation Mark Anthony Browne.

Although I've personally preferred the look and feel of natural fibers, I do understand the allure that a synthetic fabric can have. A synthetic fabric is usually less expensive than natural. Synthetics dry more quickly and with fewer wrinkles. "Performance" polyester fabric will wick moisture away from the body, (but then so will wool.) It's my understanding that the fibers from certain natural fabrics, especially those treated with dyes and other chemicals, can also contribute to the clothing fiber pollution problem. This summer I chose to reorder natural and color grown cottons. My venture into producing recycled cotton/polyester sweater knit is on hold for the time being.

My love of natural fabric runs deep. It's not just the look and feel; it's the sewing, too. When there's steam involved (as needed in the construction of a sweater) the more natural fiber, the better, as far as I'm concerned. Yes, I'm the type of person who'll always be inspired to sew based on the fabric alone. Never mind a particular style of garment or wardrobe need I may have. I publicly declared my love for natural fabric in "A Personal Look at Natural Fabrics" on PatternReview a couple of months ago.

My current thoughts on fibers wouldn't be complete without a mention of this unusual fiber. Below is a picture of a fabric, knitted with a fiber developed from natural materials -- bacteria and fungi. Could this one day be a "a sustainable alternative to conventional textiles"?

This knitted fabric was developed by a student team from the Fashion Institute of Technology for its entry in the first ever BioDesign Challenge. The BDC is a new competition created by Dan Grushkin, a writer and the founder of GenSpace, the nonprofit that promotes education in molecular biology for children and adults. Teams from nine US colleges and universities competed. It was F.I.T.'s bioyarn, knitted into a small t-shirt, that won the first prize Glass Microbe, a small sculpture by artist Luke Jerram that symbolizes the intersection of art, design, and biology. This trophy will be passed on to the next winner of the challenge. Here's a little bit about the winning group's process from the F.I.T. announcement:
The team began with observations about the wastefulness of fashion: “It’s the second most polluting industry,” they noted in their presentation. They then spent months experimenting with different formulas of the biomaterial, curious to see how much it would stretch. They tested an early version of the knitted filament in FIT’s textile testing labs, where they discovered, to their surprise, that it stretched 70 percent beyond its original length. They also customized a 3D printer to make a mesh version, which stretched 50 percent.
More about their fiber can be found on Ecouterre with lots of pics and a video, too.

Now this is the time where I'd really like to make some sort of concluding, semi-profound statement about fiber and research and the environment, but I don't have one. I'm glad that there have been some hopeful notes throughout this post. If you've got any thoughts on any of this stuff, please leave a comment. Thanks.
