Abstract

Sizing agents of coplyester-g-AA/EA's were prepared. Film properties of them such as water-resistance, swellability and tensile properties were examimed. With the increase of Ah feed ratio, film became more swellable and hence less was leer-resistant. But water-resistance of copolyester-g-AA/EA's was suntient as the sizing agent for water in loom when the molar feed ratio of AA/EA was controlled between 1/1-0.1. Tensile properties such as strength, elongation and toughness of polymer film were expected to change. Film strength decreased, film elongation increased and eventually film toughness increased. SEM photographs showed the effect of baa polymerization with the tenacious feature in the rupture phase of copolyester-g-AA/EA's compared with those of AA/EA copolymers and copolyester. Tensile properties such as strength, elongation and abrasion resistance of yarns sized with copolyester-g-AA/EA's and a copolyester were examined to confirm the fasibility of commercial usage of copolyester-g-AA/EA's.
