| titleOfInvention | Production of polyester fiber |
| abstract | PURPOSE: A specific polyester is subjected to high-orientation melt spinning, subsequently heated under specific conditions to effect simultaneous crystallization and high-temperature drawing to produce polyester fiber dyeable by the boiling method without any carrier with no formation of fluffs. n CONSTITUTION: A polyester copolymer consisting of main ehtylene terephthalate recurring units and 5-sodium sulfoisophthalic acid component is subjected to high-orientation spinning so that the optical birefringence exceeds 0.03 in the yarn after the spinning. Then, without winding up, the yarn is heated to effect crystallization to a level over 32% and high-temperature drawing by means of hot rollers at a temperature above 150°C to give the objective polyester fiber. n COPYRIGHT: (C)1983,JPO&Japio |
