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.

A polyester copolymer filament comprising:
- a composition of between about 4.5 and 5.5 percent adipic acid based on the amount of polyester copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of polyester copolymer, between about 3.4 and 4.2 percent polyethylene glycol based on the amount of polyester copolymer, and less than 2 percent diethylene glycol based on the amount of polyester copolymer.
A blended yarn comprising:
- between about 20 percent and 80 percent by weight cotton;
- and
- textured polyester copolymer staple fibers composed of between about 4.5 and 5.5 percent adipic acid based on the amount of polyester copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of polyester copolymer, between about 3.4 and 4.2 percent polyethylene glycol based on the amount of polyester copolymer, and less than 2 percent diethylene glycol based on the amount of polyester copolymer.
A dyed fabric that consists essentially of;
- a blended yarn composed of between about 20 percent and 80 percent by weight cotton;
- with the remainder being textured polyester copolymer staple fibers composed of between about 4.5 and 5.5 percent adipic acid based on the amount of polyester copolymer, between about 630 and 770 parts per million (ppm) of pentaerythritol based on the amount of polyester copolymer, between about 3.4 and 4.2 percent polyethylene glycol based on the amount of polyester copolymer, and less than 2 percent diethylene glycol based on the amount of polyester copolymer;
- and
- a reactive dye.
