纺织品耐水斑色牢度的影响因素

Influencing factors of color fastness to water spotting on textiles

为解决纺织品耐水斑色牢度不合格的问题,考察了酸、碱、盐以及后整理助剂对耐水斑色牢度的影响。结果表明,布面碱及碱式盐对耐水斑色牢度影响较大,可用适量的酸调节布面pH来改善纺织品耐水斑色牢度,但用量过多会降低水斑的边缘变色牢度级别。后整理工作液中,亲水性非反应型柔软剂会显著降低纺织品的耐水斑色牢度。

The effects of acid,alkali,salt and finishing agents on color fastness of water spottingare analyzed to solve the problem of unqualified color fastnessto water spottingon textiles.The results showed that the influences ofalkali and basic salt in fabric are moreeffective than others,and the adjustment of pH infabric with suitable acid can improve the color fastness of water spotting.However,overdose acid can decline the scale of the edge color fastness of water spotting.The hydrophilic softeners with non-reactive group was one of the most important effects that lower the color fastness of water spotting.
