摘要
涤或涤棉混纺针织物染色后传统还原清洗使用保险粉、烧碱,工艺耗时长、成本高、用水量大,排放的残液中COD值含量高。文中采用省水清洗剂RY-319A,对涤纶或涤棉混纺针织物进行还原清洗。探讨了省水清洗剂RY-319A对织物色光、染色牢度、残液COD值的影响,并与传统保险粉、烧碱工艺对比。结果表明,省水清洗剂RY-319A还原清洗工艺对涤纶或涤棉混纺针织物处理后色光及色差值与传统工艺基本一致,布面质量达到了工艺规定的要求,降低了残液中的COD值排放,可以取代保险粉、烧碱。
Sodium hydrosulfite and caustic soda is used in traditional reductive cleaning after dyeig process, the process takes a long time, has high cost and large water consumption, and the COD content in the residual liquid is high. In this paper, the water-saving cleaning agent RY-319A used to reductive cleaning the polyester or polyester-cotton blended knitted fabrics. The effects of the water-saving water cleaning agent RY-319A on the color light, dyeing fastness and COD value of the polyester or polyester and cotton blended knitted fabric was discussed, and compared with the traditional sodium hydrosulfite and caustic soda process. The results show that the color and color difference of the treated of polyester or polyester-cotton blended knitwear are basically the same as that treated with sodium hydrosulfite and caustic soda. The quality of the cloth has reached the requirements of the process regulation, reducing the COD value emission in the residual liquid, and can replace the sodium hydrosulfite and caustic soda.
