柔软剂对染后棉织物品质的影响

柔软剂可以改变染色织物的色光和牢度．棉织物先经非离子净洗剂煮练，然后用4种不同结构的硫化染料染色，染色后织物再分别经阴离子、阳离子、非离子及有机硅类柔软剂整理．结果表明：非离子型及有机硅类柔软剂改变所有染色样品的亮度L^＊．除了黄色样品的各项颜色参数有所增加外，阴离子、阳离子型和其他样品改变较少．K／S值的加权函数以在经有机硅类柔软剂整理后有大幅度增加．水洗牢度方面，蓝色样品有所减少。其他样品没有改变，所有样品的耐光牢度经柔软处理后均下降．

Effects of softeners on the cotton fibers dyed by sulfur dyes

Softeners can improve some properties of textiles,depending on the chemical nature,including soft handle,smoothness,elasticity,hydrophilic,antistatic and soil release properties.In this research,cotton fabrics were first scoured with nonionic detergent and then dyed with four sulfur dyes of different structures,then treated respectively with anionic,cationic,nonionic,micro and macro silicone softeners.The results show nonionic,micro and macro silicone softeners reduced the lightness(L*) of all sulfur-dyed samples while anionic and cationic softeners caused only a slight alteration in lightness.The a*,b* and c* values of most dyed samples show a little change after treatment with softeners except for the color coordinates of the yellow samples,which increased.A considerable increase in the fk values for silicone softener-treated samples was obtained.The washing fastness properties of blue samples decreased while they remained unchanged for other samples.The light fastness properties decreased for all samples after treatment with softeners.
