In industry, high strength polyester fiber is ideal materials for cord of tire, conveyer belt, fire hoses, cable twisted rope and fishing net. It is also used as electrical insulating materials, acid filter and deckle blanket. Non-woven fabrics made of polyester fiber are used as indoor decorative fabrics, backer of carpet, medical industrial clothes, wadding and lining. Polyester fiber has excellent wearing resistance, dimensional stability, good electrical insulating properties, light fastness, rub resistance, mould proof, mothproof. At room temperature, polyester fiber is resistant to strong acid. It has bad resistance to strong alkali. Dyeability of terylene is not ideal. Polyester fiber can only be dyed by using disperse dyes under high temperature. Polyester fiber is usually made from women’s dresses, slacks and wind coats, welcomed in the market.
