Polyester Fibre Production Process and End Uses

Introduction Polyester are polymers made by a condensation reaction taking place between small molecules, in which the linkage of the molecules occurs through the formation of ester groups. Polyesters are commonly made by interaction of a dibasic acid with a dihydric alcohol: HOOC-X-COOH + HO-Y-OH → …OC-X-COO-Y-OCO-X-COO-Y-OCO… The formation of polyester was studied by Wallace H. Carothers […]
