机器参数对变形纱性能的影响

Machine parameters and their effect on textured yarn properties

变形纱的力学性能和卷曲特性主要取决于拉伸变形机的拉伸倍数与加热器温度。2个加热辊以不同的速度运行,出丝辊与进丝辊的速度之比定义为拉伸倍数。在拉伸变形机上设置3种不同的拉伸倍数及温度,制得拉伸变形丝并测试其性能。在Himson ATH 12F/V型拉伸变形机上,保持其他试验参数(如加工速度900m/min、横向速度及上油辊速度等)不变,采用3种不同的拉伸倍数和不同主加热器温度,对规格为130D/36f(14.5tex/36f)的非混合型聚酯部分取向丝(POY)进行加工以制备试样。

Tensile behavior and crimp characteristics of textured yarn mainly depend on draw ratio and temperature of the heaters provided on draw-texturing machines.There,two heated rollers operate at different speeds,the speed ratio of output to input roller termed as draw ratio.3 different levels of draw ratio and temperature were set on a draw-texturing machine,filament produced and yarns were both tested.Polyester partially oriented yarn(POY)(non-intermingled)of 130 D/36 fwas processed on a Himson ATH 12 F/V draw-texturing machine to manufacture samples with 3 different draw ratios and changed primary heater temperatures.Other parameters like speed of 900 m/min,traverse speed,oiler roller speed etc.were kept the same.
