摘要
采用测色的方法,研究了常规涤纶纤维和超细涤纶纤维织物上分散染料的扩散性能、耐熨烫牢度、耐皂洗牢度及摩擦牢度的关系。实验结果表明:分散染料的耐熨烫牢度和耐皂洗牢度随染料扩散系数的增大而降低,熨烫变色程度ΔE与染料的扩散系数基本上呈线性关系;皂洗沾色程度不仅与染料扩散性能有关,还与染料对纤维的亲和力、染料在皂洗液中的状态等因素有关,在超细涤纶纤维染色织物上,分散染料的扩散性能对耐熨烫牢度和耐皂洗牢度的影响更加明显,在充分去除浮色的条件下,分散染料的扩散性能对摩擦牢度无影响。
The influence of diffusibility of disperse dyes on color fastness to ironing, soaping and rubbing of both ordinary and superfine polyester fibers was studied by color measurement. The results show that the color fastness of disperse dyes to ironing and soaping deteriorates as the diffusion coefficient of dyes increases. There is a linear relationship on the whole between the fading extent （ A E） of dyed fabric and the diffusion coefficient of disperse dyes in ironing. The staining extent of polyester fabric in soaping is not only determined by the diffusibility of dyes, but also affected by the affinity and the state of dyes in soaping bath. The diffusibility of disperse dyes has a more remarkable influence on color fastness to ironing and soaping of superfine polyester fiber. However, the diffusibility of disperse dyes has little influence on rubbing fastness provided that the unfixed dyestuff on fabric has been entirely removed.
