What is P.E.T.?P.E.T.(polyethylene terephthalate) polyester is one of the strongest man made fibers. It's versatility, durability, and inherent resistance to stains make it PET the popular choice for a variety of consumer goods ranging from seat belts to tire cords to carpet. In fact, polyester is the most used synthetic fiber in the world.

How does recycling affect the quality of PET fiber?
Due to the high intrinsic viscosity requirements of the bottle industry, bottle-grade PET resin is superior to virgin carpet-grade resin in terms of strength. This characteristic is retained through the recycling process due to the fact PET is a thermoplastic material which can be melted and reformed with virtually no change in physical properties. The superior nature of PET as a raw material is unchanged by recycling.
How does PET compare with other carpet fibers, such as nylon?
PET fibers offer very distinct advantages--- superior and permanent stain resistance, strength and abrasion resistance, permanent static resistance, rich true colors, and low moisture absorption. Because PET is used in products such as seat belts and tire cords it must meet federal strength requirements that are not applied to other fibers used in the production of carpet.
