    摘要： 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.- 300.degree.C and a final pressure of less than 10 mm mercury to form an anhydrous melt. A substituted cyclobutanedimethanol, preferably 2,4-diphenyl-cyclobutanedimethanol-1,3, is added to the melt-polymerization at a concentration of about 0.05 - 5 mole percent of the substituted cyclobutanedimethanol component. Melt spinning of the modified polyester is carried out and the fibers are irradiated with high energy light.

    摘要： 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.-300.degree. C and a final pressure of less than 10 mm mercury to form an anhydrous melt. A vinyl copolymer having more than two carboxyl and/or hydroxyl groups is added to the melt polymerization at a concentration of about 0.005 to 2.0 percent referred to the dicarboxylic acid component. Melt spinning of the modified polyester is then carried out. The vinyl copolymer has the following general formula- ##STR1## where N IS AN INTEGER FROM 10 TO 10,000;a is zero or an integer from 1 to 100;b is an integer from 1 to 100;R.sup.1 through R.sup.6 are hydrogen, an alkyl group with 1 to 3 carbon atoms or an oxalkyl group -OR.sup.7 ;R.sup.7 is an alkyl group with 1 to 6 carbon atoms or an aryl group with 6 to 10 carbon atoms;X.sub.1 is hydrogen, an alkyl group with 1 to 3 carbon atoms, or a carboxyl group, an esterified carboxyl group; andX.sub.2 is a carboxyl group, a hydroxyl group, an esterified carboxyl group or an esterified hydroxyl group.
