POLYESTER COMPOSITION WITH IMPROVED DYEING PROPERTIES |
| 摘要 |
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. |

1. A method of spinning a polyester copolymer filament comprising the steps of:
polymerizing terephthalic acid, ethylene glycol, between about 4.5 and 5.5 percent adipic acid, between about 630 and 770 ppm pentaerythritol, and between about 3.4 and 4.2 percent polyethylene glycol to a copolymer melt with less than 2 percent DEG; at an intrinsic viscosity of between about 0.58 and 0.82 and at a temperature of between about 285° F. and 295° F.; with the proportional amounts being based on the amount of polymerized copolymer; and spinning the resulting polyester copolymer melt into filament. |
