Document Summary

Concern for the environment has led to a plan for recycling pet soda pop bottles into fiber.

The carpet industry also produces polyester and nylon carpets that are totally recyclable. A new polyester, with a brand name of corterra, was introduced in 1999. It is used in carpets and textiles for home and garments and automobiles. It is made from polymethylene terephthalate (pmt) U. s. producers include: dupont (tyvek and typar non-woven fabrics), allied (spectra high tenacity fiber), and hercules (herculon fiber) Starting materials are polymers manufactured from chemicals derived from petroleum. The polymers are not found in nature. Polypropylene (pp) is used to make olefins. Produced by addition polymerization of propylene or ethylene. Polymers are melt spun for conventional olefins (pp) Olefins are used in either filament or staple form. Low density: 0. 92 (
