摘要
为研究包芯纱的最小包覆量,从纱线的纤维排列模型入手,分别推导以单丝和复丝为芯的包芯纱最小包覆量计算方法,并通过实例计算和试纺分析,研究实际生产中低包覆量包芯纱出现露芯现象和条干不匀的主要原因。结果表明,通过简单的建模和计算,能方便地估算出理论最小包覆量,在生产应用中为得到较好包覆效果,实际包覆量应大于理论最小包覆量,并通过原料选择、工艺设置、器材选配等多方面的优化措施,以获得满意的成纱质量。
To assess the minimum coating amount on core-spun yarn,the approach of yarn fiber array modeling is taken to develop a calculation methodology of minimum coating amount on core-spun yarn made from monofilament and multifilament respectively.Through practical calculation and trial spinning of samples,primary causes of dew core defect and unevenness of strips in actual production of low coating package are analyzed.The result proves a simple modeling and calculation can give estimation of theoretical minimum coating amount conveniently.In real production,actual coating amount shall be more than theoretical one to achieve sound coating effect.In combination of other measures such as raw material selection,process setting and optimum equipment matching,yarn quality is assured of the satisfaction.
