The elastomeric wool-like composite false-twist yarns

Abstract

In the experiment, the physical properties of the polyester fiber have been changed after the processing by the false twisting machine. The product has good the elastic and wool like, which called processing yarns. According to the fiber has better properties by these parameters which are 200℃, the twist 2400 T/M and Air jet pressures 2.4kg/cm2. The composite fiber core wire has been divided two types by DPF. The bigger DPF diameter of the fiber, has high-strength, good backlash and high elastic force properties. On the other hand, smaller DPF diameter of the fiber, has softer touch. Good elastic resilience and softness can be made from the false twisting machine processing by using the 4T of the conditions, appropriate parameters.

摘要

本實驗利用假撚機及聚酯纖維之熱可塑性，對物理性質產生變化；製作出彈性及毛性加工紗。由研究結果得知，溫度設定200℃、撚度在2400T/M、Air jet壓力於2.4kg/cm2，可得較佳之纖維型態。複合纖維芯線，由纖維直徑DPF較大者，可得到高強度纖維、反撥性佳及高彈性力之物理特性；皮線以纖維直徑較小之DPF，可獲得較柔軟之觸感。利用假撚機加工條件之4T取適當參數，即可得良好彈性回復力及柔軟度。
