This is a new type of fiber that has a long chemical name, Polyethylene Terephthalate, but still falls in the class of fibers know commonly as Polyesters. This fiber has natural and permanent stain resistance. Polyester fiber is strong and compares with Nylon in strength and abrasion resistance. Unlike the old Polyester, the new Polyester product has a higher melting point equivalent to type 6.6 Nylon. The fiber is made from Polyethylene Terephthalate (PET) chips, some of which come from recycled plastic containers, hence the name "pop bottle carpet". Recycling does not affect the quality if the fiber, thus this product could be a future fiber that could be recycled over and over.
