半精纺系统加工地毯纱的工艺探究

Study on semi-worsted carpet yarn processing

主要研究使用半精纺系统加工机制地毯纱工艺,以使纱线适合不同地毯织机的使用和地毯质量的要求。半精纺地毯纱加工工序包括和毛、梳理、针梳、细纱及合股4个部分。通过对其工艺的分析,得出使用半精纺工艺具有系统加工成本低、加工流程短、制成率高、适应性强等优势。和毛是将各种原料成分混合均匀,避免在地毯上出现条痕、斑点、色花等瑕疵;梳理是对纤维进一步梳理混合而形成毛条;针梳是通过进一步梳理牵伸而形成适合纺不同支数纱线的毛条;细纱及合股是对针梳毛条进行牵伸加捻及再加捻,生产出适合不同地毯织机所要求规格的地毯纱线。

This paper mainly discuses how to use semi-worsted system to produce machine-made carpet yarn which can be suitable for different carpet machines processing and meet the high quality requirement of machine-made carpet yarn.Semi-worsted processing includes blending,carding,gilling,spinning and doubling etc.By the study and analyses on semi-worsted processing,the advantage of low production cost,short processing,high processing yield and adaptability of semi-worsted are introduced.Blending can mix different materials evenly in order to avoid streaks,stains and dyeing problem on carpet; carding is the role of carding fiber blocks into a single fiber and further blending more evenly;gilling is making sliver carded into suitable size which is matching different yarn count of spinning delivery by drafting and gilling; spinning and doubling is just drafting and twisting to different yarn which can satisfy for different yarn specification for carpet machines processing.
