A full dull polyester yarn, and a process of preparing for the same

摘要

This invention is in the manufacture of polyester fiber in a high-speed spinning , the crystallization increases sharply on the radiation and developing ( radiation crystallization ) to effectively buy books because delays matt polyester part orientation characterized by manufacturing a high-speed spinning (4,500m above / min). The present invention was added titanium dioxide 0.5% by weight 0.5 to 5.0 parts by weight of crystalline orientation during polymerization inhibitor polyester containing at least % for this by uniformly mixing them and then continuously hardness of 2,500 or higher by using a ceramic guide 4,500m / emission rate , in minutes or more , and the take-up . The invention is to improve the productivity of producing a matte polyester oriented yarn at a high speed , and improve the fairness of such false-twist spinning and drawing , and Choi, Jong - Won 's quality can be improved .
