摘要
分析POY条干不匀率对DTY各项CV %值的影响 ,发现二者之间存在线性关系。降低前者的方法有加强对工艺和设备关键点的监控 ,调整侧吹风风速为 0 .40～ 0 .6 0m/s ,卷绕张力为 1.8～ 2 .2N ,接触压力 10 0～ 110kPa及降低锭位差异等 ,可以提高DTY的质量。
Effect of yarn irregularity of POY on different CV % of DTY is analysed, the linear realation between the above two are discovered. The method of decreasing the yarn irregularity of POY is to strengthen the key point control of process and equipment,adjusting the cross air blow speed to 0.40 ～ 0.60 m/s, the take-up tension to 1.8～2.2 N, the contact pressure to 100～110 kPa and decreasing the spindle difference etc.The quality of DTY should be increased.
