False twist-crimped polyester yarns and process for their production |
| abstract |
A false twist-crimped polyester yarn having a density d of 1.3800 </= d </= 1.3950 (g/cm3) and a total percentage crimp (TC) of TC >/= 30% is produced by false twisting a polyester multi-filament having a birefringence ( DELTA n) of 0.030 </= DELTA n </= 0.145 while heat setting the filament in the twisted state at 160 DEG to 210 DEG at a draft (dr) which satisfies the following equation: -250. DELTA n + 38 >/= dr >/= - 150. DELTA n + 17 Heat-setting the above false twist-crimped polyester yarn at a higher temperature gives a modified false twist-crimped polyester yarn having a density (d) of 1.3800 </= d </= 1.3950 (g/cm3), a total percentage crimp (TC) of TC </= 20%, and a torque (Tq) of Tq </= 26 (T/25 cm). |
