粗梳羊绒纺纱抗静电剂用量的差异化比较

Optimization of the amount of antistatic agent used in carding cashmere spinning

在纺纱和毛工序一般会加入定量的抗静电剂来减少纺纱过程中的静电现象,但大量生产实践发现,在车间湿度超过85%的条件(南方高湿地区)下,纤维易与梳毛机产生黏附现象,降低生产效率。为解决这一问题,设计粗梳羊绒纺纱实验,分析抗静电剂(FX-AS301)的用量与车间湿度的关系。保证车间温度及其他工艺参数相同,对比分析不同抗静电剂用量及湿度的条件下,纺纱的难易程度、纱线的物理指标及所织织物的起毛起球性能。结果表明:不同车间湿度下,将抗静电剂质量分数从1.0%降低到0.5%时,可以降低纤维与机件间的黏附情况;当抗静电剂用量一致(0.5%或1.0%)时,车间湿度为65%和75%时的成纱质量相对更高;当车间湿度较大(85%)时,降低抗静电剂用量可以在降低纤维与机件间黏附情况的同时改善成纱质量。文章可指导高湿地区的纺纱生产,控制企业生产成本,提高生产效率。

In the wool blending processes,it is common to add quantitative amount of antistatic agents to reduce static electricity during the spinning process.However,under conditions where the workshop humidity exceeds 85%(high humidity areas in the south),fibers tend to adhere to the carding machine,reducing production efficiency were found in the mass production practice.To solve this problem,an experiment was designed to analyze the relationship between the amount of antistatic agent(FX-AS301)and workshop humidity.Ensure the same workshop temperature and other process parameters,the difficulty of spinning,the physical indicators of the yarn,and the pilling properties of the fabric under different antistatic agent dosage and humidity conditions were compared and analyzed.The results show that when the mass fraction of antistatic agent is reduced from 1.0%to 0.5%under different workshop humidity,the adhesion between fibers and components can be reduced;When the amount of antistatic agent is consistent(0.5%or 1.0%),the workshop humidity is 65%and 75%,the yarn quality is higher than the workshop humidity of 85%;When the workshop humidity is high(85%),reducing the amount of antistatic agent can improve yarn quality.This paper can guide spinning production in high humidity area,control production cost and improve production efficiency.
