There is a synthetic fabric out that is green. It is also stain resistant and chemical and PFC free. This fabric can be cleaned with bleach, and it is affordable. The fabric is a byproduct of refining petroleum. It used to be discarded or burned off, but not anymore.
The great thing is not only is this fabric amazing for all of the above reasons, but it is also beautiful.
The scientists who discovered this process won the Nobel Prize for Chemistry.
