摘　　要：以POY纤维为生产原料,通过调整加弹工艺中的牵伸倍数、变形温度和网络气压3个参数值,探讨了涤纶网络丝生产工艺对其网络牢度及M率的影响。试验结果表明:3个工艺参数对网络牢度的影响程度为网络气压>牵伸倍数>变形温度,对M率的影响程度为变形温度>牵伸倍数>网络气压。利用正交试验极差分析可得,当牵伸倍数为1.72、变形温度为205℃、网络气压为0.43 MPa时生产涤纶网络丝,其产品网络牢度达99.5%,同时M率可达97.5%,网络牢度高、染色均匀性好,可广泛应用于高档窗帘面料的生产。In this paper, POY fiber is used as raw material to research the impact ol the polyester mterlaceu yarn production process on its interlacing intensity and M rate through adjusting the parameters of draft ratio, deformation temperature and interlacing pressure in the draw texturing process. The experimental results shows that impact of these three parameters on interlacing intensity are in the following order： interlacing pressure 〉 draft ratio 〉 deformation temperature; impact on M rate are in the following order： deformation temperature 〉 draft ratio 〉 interlacing pressure. In analysis of orthogonal experiment range, when the draft ratio is 1. 72, the deformation temperature is 205 ℃, and interlacing pressure is 0.43 MPa, the interlacing intensity of polyester interlaced yarn can reach 99.5% , and its M rate can reach 97.5%. This kind of polyester interlaced yarns has high interlacing intensity and uniform and even dyeing. It can be widely used in high-grade curtain fabric production.
