涤棉分散/活性一浴高效低泡防沾污净洗剂的制备与应用

Preparation and Application of the High Efficiency and Low Foam Detergent in Dyeing of Polyester/Cotton Fabrics with Disperse/Reactive Dyes

针对当前涤棉分散/活性一浴染色或印花后浮色(未固着的染料、水解染料)难以洗净、色牢度不佳及白底反沾等不足,通过引入具有低表面张力的聚乙二醇/聚硅氧烷嵌段共聚物组分、磺酸盐组分、吡咯烷酮和酰胺基团等制得一种侧链含聚醚硅结构高效低泡防沾污净洗剂,提高防沾污净洗剂的渗透性、分散能力,提高其防沾污能力,继而保证纺织品的色牢度和鲜艳度。自制的侧链含聚醚硅结构高效低泡防沾污净洗剂不含烷基酚聚氧乙烯醚(APEO)、邻苯二甲酸酯和有机磷化合物等有害物质,是一种环境友好的印染助剂材料。试验结果表明自制高效低泡防沾污净洗剂的净洗性能和防沾污性能优异,净洗处理后的染色织物具有较好的色牢度。

In view of the current shortcomings of polyester/cotton disperse/reactive one bath dyeing or floating colors of printing fabrics(unfixed dyes,hydrolytic dyes),such as difficulty in cleaning,poor color fastness,and anti staining of white background,an efficient low foam&anti contamination detergent containing polyether silicon structure with side chain was prepared by introducing polyethylene glycol/polysiloxanc block copolymer component with low surface tension,sulfonate component,pyrrolidone and amide group,to improve the permeability and dispersion ability of the anti contamination detergent,improve its anti contamination ability,and then ensure the color fastness and brightness of textiles.The self-made high efficiency low foam anti contamination detergent containing polyether silicon structure docs not contain alkyl phenol polyoxycthylene ether(APEO),phthalates,organic phosphorus compounds and other harmful substances,and is an environment-friendly printing and dyeing auxiliary material.The experimental results showed that the self-made high-efficiency low foam anti staining detergent had excellent cleaning performance and anti staining performance,and the dyed fabric after cleaning treatment had good color fastness.
