针织大圆机用半精纺纱的纺纱工艺探析

Spinning Process Analysis of Semi-spinning Yarn for Large Circular Knitting Machine

探讨针织大圆机用半精纺纱的纺纱工艺措施。根据针织大圆机的生产特点和织物质量要求,制定了半精纺纱的内控质量标准,采取了一系列关键技术措施。优选原料及其配比,做好纺纱前的调色配色与打样工作,重视原料的预处理及混和,同时优选梳理设备和梳理工艺,安装自调匀整系统,采用新型设备及技术等,确保纺纱质量符合针织大圆机用纱的要求。认为:半精纺纱线提高了针织大圆机产品的附加值,拓宽了半精纺纱的应用领域。

Spinning process measures of semi-spinning yarn on large diameter circular knitting machine were discussed.According to production characteristics of large diameter circular knitting machine and fabric quality requirements,internal control quality standard for semi-spinning yarns was formulated and a series of key technology measures was adopted.Raw materials and their ratios were optimized,better color matching and proofing before spinning were done.Pretreatment and mixing of raw materials were paid attention to.Carding equipment and carding processes were optimized.Auto-leveling system was installed.New equipment and technologies were adopted to ensure spinning quality meet yarn requirements for large diameter circular knitting machine.It is considered that semispinning yarns increase the added value of large diameter circular knitting machine and broaden the application fields of semi-spinning yarn.
