介绍采用预取向丝—拉伸变形丝(POY—DTY)工艺路线生产167 dtex/288 f经编珊瑚绒用多孔细旦涤纶拉伸变形丝(DTY)的生产技术。结果表明:提高纺丝温度,延缓冷却条件,适当提高集束上油位置,降低纺速,增加POY预网络,加弹选用硬度偏低的聚氨酯摩擦盘及优化组合,增加预网络工序,并选择低的中网络压力,选择合适的工艺参数,可以生产出满足经编珊瑚绒用多孔细旦涤纶DTY。
This paper introduces the production technology of 167 dtex / 288 f warp coordered porous fine denier polyester textured yarn (DTY) by pre-oriented POY-DTY process. The results show that: increasing the spinning temperature, slowing down the cooling conditions, appropriately increasing the oiling position in the bundles, reducing the spinning speed, increasing the POY pre-network, adding the polyurethane friction plate with low hardness and optimizing the combination, increasing the pre-network process, Of the network pressure, select the appropriate process parameters, to meet the production of warp coral fine porous polyester DTY.
