纯涤短纤维经纱上浆工艺研究

Research on Sizing Technology of Pure Polyester and Short\|staple Warp

探讨纯涤短纤维织物浆纱生产工艺。针对纯涤短纤维纱的特点,分析浆纱中存在的主要问题。通过优化浆料配方、加大浆槽和湿区的纱线张力、降低浆纱回潮率、调整蜡辊与浆纱的速比、控制浆槽温度,同时精细化浆纱操作等措施。使浆纱成本降低,喷气织机效率有所提高。生产实践表明：纯涤短纤维纱浆纱浆料配方既要考虑浆料对纯涤短纤维的粘附性,又要保证干分绞顺利,减少再生毛羽；浆轴回潮率控制在0.5%～1.5%之间,有利于织造的顺利进行。

This paper discusses the sizing production process of pure polyester and short／｜ staple fabrics;analyzes main problems existing in sizing according to characteristics of pure polyester and short／｜staple yarn;reduces the cost of sizing and improves the efficiency of air jet loom by optimizing sizing agent formula,increasing the tension of yarn in stock tank and wet area,reducing the moisture regain of sizing,adjusting the speed ratio of wax roll and sizing and controlling the temperature of stock tank and meanwhile refining sizing operation. The production practice shows that sizing agent formula of pure polyester and short／｜staple yarn should not only consider the adhesion of sizing agent to pure polyester and short staple, but also ensure smooth dry lease and reduce regenerated hairiness;the moisture regain of loom beam controlled between 0.5%and 1.5%is conducive to smooth weaving.
