摘要

A LINEAR CRYSTALLINE TEREPHTHATLATE POLYESTER YARN AND TEXTILE GOODS MADE THEREFROM Novel polyester filamentary yarn is provided having (a) a fineness of 0.9 denier per filament or less, (b) an amorphous orientation in the range of 30% to 70% and (c) a negative .epsilon.0.2 where said .epsilon.0.2 is a structural integrity parameter. The yarn possesses improved properties relating to heat-setting, raising, dimensional stability and twist resistance. The yarn finds its wide range of usage, for example, silky fabrics with an excellent fullness, pliability and liveliness, raised fabrics with thermally stabilized fluffs protruding straightforwardly and an extremely soft hand, and uniformly creped fabrics with an improved surface contour are obtained therefrom.
