There’s been hand-wringing aplenty this year as cotton prices have risen to heights not seen since the Reconstruction. (Think 1870, readers, not 2008.) Yet while the price of a pound of cotton tipped historic heights of $1.52 on November 10, garment manufacturers are hedging their bets. Raw materials make up between a quarter and half of the cost to produce a garment, so many haven’t purchased their supply of cotton hoping the price will drop. It has, a bit. Friday saw a decrease to $1.37.
In the meantime, several firms are busy engineering textiles that may provide a more sustainable—not to mention economical—alternative to “the fabric of our lives.”
Flax: not just for breakfast anymore
We often think of flax as a health supplement. Indeed, the seeds of the plant have been touted to cure what ails by the likes of Charlemagne. But Naturally Advanced Technologies (NAT) figured out a way to blend the fibers with cotton to decrease production costs without the use of synthetics.
Developers of the proprietary CRAiLAR process, CEO Ken Barker says, “CRAiLAR flax is a cost-effective choice that won’t force consumers to sacrifice cotton’s desirable qualities.” Not to mention that it’s abundant, and can be processed twice as efficiently as hemp.
But how does it feel? Like cotton, CRAiLAR flax is soft and great for use in standard issue T-shirts and jeans. Barker goes so far as to call it, “a plug-and-play for cotton.”
More than that, notes Barker, it’s a potential solution to a global crisis. It’s cheaper than cotton, and flax requires no irrigation and little or no chemical fertilizers and pesticides. Organic flax can be grown in rotation with any other organic crop, for complete organic certification.
Says Barker, “Right now large brands are looking to reduce their cotton footprint with a more sustainable natural fiber alternative, as opposed to increasing their consumption of organic cotton, which is even more expensive than cotton, and harder to grow.”
The first CRAiLAR flax garments should hit the racks in Fall 2011.
Replacing PET one fiber at a time
Natalia Allen (Design Futurist) and Stephen Miller are hard at work to further a sustainable fashion economy sans “gimmicks and greenwashing.” To that end, the two are taking a hard look at the PHFA polymer—originally designed to be a replacement for PET (polyethylene terephthalate) commonly found in water bottles.
Says Allen, “Just as PET is used in packaging AND textiles, we determined that PHFA could also have dual use applications. While cotton is bio-based and biodegradable, we hope to further expand the number of fibers that have these two qualities.” The primary feedstock is designed to come from lignin, a major component of all vascular plants. Acetic acid, the key ingredient in vinegar, is the minor component.
Allen and Miller are working to make the textile price competitive, but she sees it as more of a replacement for polyester. “Cotton relies heavily on petroleum-based fertilizers and pesticides. Polyester feedstocks are usually petroleum—or natural gas-based. However, our product is currently made from biomass and has a great potential to be made on very large scale from biomass.”
Look for the Allen/Miller textile to debut in the next couple of years.
