水刺非织造用短纤维质量特性及生产控制浅析

摘要

This article describes the advantages of spun-laced non-woven fabric.It generalizes the process and analysis the quality requirements towards raw fiber of feeding,carding,web formatting,spunlacing and drying procedures of opening tangled cotton for spun-laced non-woven fabric.According to the above quality requirements,it brings up the technical routs alternatives for specialized stable fiber and confirms the characteristic value of quality of specialized stable fiber for spun-laced non-woven fabric and clarify the difference between specialized material and common stable fiber high-strength cotton type on elongation at break,breaking tenacity,defect content,dry and thermal shrinkage,oil content ratio and so on.It brings up the increasing assurance on controlling process of non-fiber impurities and the site cases of controlling of non fiber impurities according to the feedback from the clients.It analysis the site management control to the flaw impurities.%描述了水刺非织造布的优势。概述水刺流程,分析了水刺非织造布各工序对原料纤维的质量要求。根据上述质量要求,提出了水刺专用短纤维工艺路线,确定了水刺非织造用短纤维质量特性值,说明了专用料和普通高强棉型短纤维在断裂伸长率、断裂强度、疵点含量、干热收缩率、含油率项目上的不同之处。根据用户反映信息提出了管控非纤异物现场方案。分析了疵点杂质产生的过程,提出了疵点杂质现场管控要点。
