| 摘 要： | 介绍了熔体直纺生产205 dtex/192f细旦扁平涤纶预取向丝(POY)的工艺路线,并讨论了纺丝温度、冷却成形、上油位置及方式、卷绕工艺、喷丝板选型等对生产细旦扁平涤纶POY的影响.结果表明:选择较高的纺丝温度,严格控制环吹风条件,适当提高集束点位置,优化上油均匀性,降低纺丝速度,适当提高卷绕张力,降低成型角,可制得质量较好的细旦扁平涤纶POY.

| Abstract: | The process route of 205 dtex/192 f fine denier flat POY by melt direct spinning was introduced.Moreover,the influence of spinning temperature,cooling condition,oiling position and mode,winding process and selection of spinneret on fine denier flat POY were studied.The good quality of fine denier flat POY was produced by adjusting process conditions such as higher spinning temperature,strictly control cooling condifion,heighten yarn collection position,optimum oiling uniformity,lowering spinning speed and increase yarn winding tension. |
