摘　　要：条干不匀率是表征双组分弹性纤维的一个极其重要的质量指标,可由U值、CV值、Uhi值来表示,它的大小影响成品的后加工性能。而影响双组分弹性纤维条干不匀率的因素是多方面的,本文以消光双组分弹性丝(88 dtex/48 f)为例,探讨了侧吹风风速、风筒高度、底部加热器温度、油嘴类型、油架高度、喷丝板种类对双组分弹性纤维条干不匀率的影响因素。Yarn unevenness is an extremely important quality index to characterize two-component elastic fiber.It can be expressed by U value,CV value,and Uhi value.Its size affects the post-processing performance of the finished product.There are many factors that affect the unevenness of bi-component elastic fiber slivers.This article takes the extinction matte two-component elastic yarn(88 dtex/48 f)as an example to discuss the side blowing wind speed,the height of the air duct,the temperature of the bottom heater,and the type of nozzle.The height of the oil stand,and the type of spinneret affect the unevenness of the b-component elastic fiber.
