摘要
结合皂洗牢度和反射率曲线考察了棉织物上分散红 60的皂洗变色现象和助色基团对皂洗变色程度的影响 ;通过电子透射和衍射图分析了染料在棉纤维中的状态和分布。结果表明 ,导致分散红 60皂洗变色的主要原因是蒽醌环上电负性 (助色基团 )分布不均及晶体在纤维中的重排。
The appearance of color change after soaping and effect of the auxochromic group on the degree of color change of C.I. Disperse Red 60 in cotton fabric were observed by means of soaping fastness and reflectance curve, the state and distribution of the dye in the fiber were analyzed by electronic transmitting and diffracting pictures in this paper. The result showed that the color chang after soaping was mainly caused by re-distributing of the dye in cotton fiber.
