Abstract
A copolymer composition is disclosed with advantages for textile fibers, yarns, blended yarns, fabrics, and garments. The composition includes polyester copolymer, between about 4.5 and 5.5 percent adipic acid based on the amount of copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of copolymer, and between about 3.4 and 4.2 percent polyethylene glycol based on the amount of copolymer.
Claims16
A filament comprising:
- a polyester copolymer comprising about 4.5 and 5.5 percent adipic acid based on the total amount of polyester copolymer,
