Assignment on Polyester Fiber

POLYESTER FIBERS: Polyester fiber is a manufactured fiber in which the fiber forming substance is any long chain synthetic polymer composed at least 85% by weight of an ester of a dihydric alcohol (HOROH) and terephthalic acid (p-HOOC-C6H4COOH) [3] The most widely used polyester fiber is made from the linear polymer poly (ethylene terephtalate) and this polyester
