摘要
为了解决尼龙6弹力变形纱(DTY)在退绕过程中的打结和断裂问题,根据尼龙6 DTY的加工技术和设备确定了78 dtex/24 f DTY的加工程序。假设没有羊毛,没有紧密扭曲,没有网眼并且没有均匀的弹性,则将超喂率设置为3.0%,横向角度为22°,并且包装硬度达到68 HS,放卷速度可以大大提高,达到1800 m/min。
To solve the knotting and breaking problem of nylon 6 draw textured yarn(DTY)during unwinding,the processing procedure of 78 dtex/24 f DTY was determined according to the processing technology and equipment of nylon 6 DTY.Assuming that there is no wool,no tight distortion,no mesh and no uniform elasticity,the overfeeding rate is set to 3.0%,the transverse angle is 22°,and the packing hardness reaches 68 HS,the unwinding speed can be greatly improved to 1800 m/min.
