When it comes to being eco-friendly you may have decided to opt for organic cotton or perhaps sustainable fabrics like bamboo, but have you thought about your zipper? Ideal Fastener Corp. has announced that they will be using Repreve recycled yarn in the zipper tape for a new line of products called the Ideal Earth brand. The Repreve yarn is made out of 100-percent-recycled materials reducing the need for virgin polyester. The two companies say that every 150 Ideal Earth jacket zipper tapes or 500 IDEAL Earth™ pant zipper tapes manufactured with Repreve is equivalent to one gallon of gasoline saved. That's not a huge number but it's a start. Now how do they go about making the rest of the zipper eco-friendly?
