Abstract
A copolymer composition is disclosed with advantages for textile fibers, yarns, blended yarns, fabrics, and garments. The composition includes polyester copolymer, between about 9.5 and 10.5 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.
Claims17
A polyester copolymer filament comprising:
- a composition of between about 9.5 and 10.5 percent adipic acid based on the total weight amount of polyester copolymer,
