PLA

it's cool shit. It is an artificial fabric that is made from corn, and it's properties can be changed very easily. Although the distillation process is the same as that of synthetic fibers, It's way more environmentally friendly to produce than synthetic fibers (which are made of plastic). PLA is relatively new, it came out in 2002. They're still tweaking it a little to make it a little easier to dye bright colors. I really want to get my hands on some!!!
