摘要(Abstract)：
通过对熔体质量和工艺条件的选择,采用喷丝板孔径0.13mm,纺丝温度296℃,侧吹风风速0.35m/s,集束点位置600～700mm,纺丝速度2750m/min,以及适当控制其它工艺条件,纺得涤纶POY微细旦丝的断裂强度2.48cN/dtex,断裂伸长率127.6%,可满足后加工要求。
By selection of suitable polymer and process condition of spinneret orifice 0.13 mm, spinning temperature 296 ℃, quench air velocity 0.35 m/s, spinning speed 2 750 m/min and filament collection position 600~700 mm, the fine denier POY with strength tenacity 2.48 cN/dtex, elongation at break 127.6 % was obtained.
