Abstract

PURPOSE: To prevent the occurrence of broken fibers and the reduction in the product strength, by using a polyester, consisting of terephthalic acid component and ethylene glycol component essentially, and having a specific spherulitic diameter.
CONSTITUTION: In melt spinning a polyester at a taking off speed ≥2,000m/min, a polyester obtained by esterifying a bifunctional carboxylic acid consiting of terephthalic aic essentially and a glycol consisting of ethylene glycol essentially in the presence of a crystallization inhibitor, preferably sodium acetate, and polycondensing the resultant esterification reaction preduct is used as the polyester. The polyester has a spherulitic diameter ≤15μm measured by a differential scanning calorimeter.
