摘要(Abstract)：

为解决锦纶6拉伸变形丝(DTY)在退绕过程中易出现打结、断头的问题,从锦纶6 DTY的加工工艺、设备部件等方面入手,确定了加工常规78 dtex/24 f DTY时,在保证无毛丝、紧捻、网丝、弹性均匀的前提下,设定超喂率为3.0%,交叉角为22°,卷装硬度达到68 HS时,退绕速度可大幅提高,达到1800 m/min。
The conventional nylon 6 draw textured yarn(DTY) is mainly used in strap weaving industry.The knot and broken ends are increased during the unwinding process of nylon 6 DTY.With the improvement of processing parameters and machine parts,the optimum conditions such as super-feeding 3.0 %,angle of crossing 22°,package hardness 68 HS are selected for conventional 78 dtex/24 f DTY.The result showes that no broken filament,no hard twist and no spider-web filament are found during the texturizing,and unwinding rate is 1 800 m/min.
