介绍了通过优选原辅料,设计适宜的干燥工艺,优化纺丝温度,调整侧吹风工艺参数,优化拉伸工艺,确保生产工艺的一致性,可生产出沸水收缩率在2.0%~2.5%较低范围内的有色涤纶膨体变形丝(BCF),再经过加捻定形,制得应用于织造割绒地毯绒面的地毯纱。
This paper introduces that through optimizing raw and auxiliary materials, designing proper drying process, optimizing spinning temperature, adjusting the side blowing process parameters, optimizing the stretching process and ensuring the consistency of the production process, it can be found that the shrinkage rate of boiling water can be reduced from 2.0% to 2.5% Range of non-ferrous polyester fiber textured yarn (BCF), and then through the twisting and setting, the system used in weaving carpet cut velvet carpet yarn.
