影响棉上C.I.分散蓝14的皂洗变色因素分析

Analysis on the Efecet Factors and Mechanism of Color―change to Soaping Of C.I.Disperse Blue 14 on Heat Transfer Printed Cotton Fabric

为了研究C.I.分散蓝14热转印棉织物皂洗变色的影响因素,探讨了架桥剂、温度、水和皂液浓度对热转移棉织物上C.I.分散蓝14颜色的影响,同时结合色度参数和反射率曲线考察了棉织物上C.I.分散蓝14皂洗变色现象。结果表明皂液浓度对热转印棉上C.I.分散蓝14皂洗后的颜色变化具有一定的影响,主要影响因素为水和皂液的温度,且颜色的变化随着温度的升高而增大;架桥剂本身对颜色的变化无显著影响。

In order to study the factors influencing color-change after soaping of C. I. Disperse Blue 14 on heat transfer printed cotton fabric ,the effect of bridge-agent,temperature,water and concentration of soap liquor on the color of disperse blue 14 on heat transfer printed cotton was tested. Combined with chromatic parameters and reflectance curve,the appearance of color-change after soaping of C. I. Dis- perse Blue 14 was observed in this paper. The results showed that the bridge-agent and concentration of soap liquor have some effect on the color-change which was mainly caused by the water and the temperature of soap liquor, and the higher the temperature is,the larger the degree of color change is. Bridge-agent itself has no obvious effect on the color change.
