ABSTRACT:
An improvement in the process of melt spinning ethylene terephthalate polyester to produce textile fibers with decreased pilling in the threads, fibers or fabrics made therefrom. The ethylene terephthalate is melt polymerized in the presence of a condensation catalyst to a final temperature of about 250.degree.C - 300.degree.C and a final pressure of less than 10 mm mercury to form an anhydrous melt. A substituted cyclobutanedecarboxylic acid, preferably .alpha.-truxillic acid, is added to the melt-polymerization at a concentration of about 0.05-5 molepercent of the acid component. Melt spinning of the modified polyester is carried out and the fibers are irradiated with high energy light.
