Study on Dyeing Properties of CDP Fibers with Different Types of Cationic Dyes
Based on the characteristics of traditional cationic dyes,this paper systematically compares the characteristics of traditional cationic dyes and dispersed cationic dyes in terms of dyeing temperature,bath pH,dyeing bath ratio,dyeing time and dye dosage,and optimizes the dyeing process and dyeing applicability,the optimized process is as follows:dyeing temperature 120℃,pH 4～6,bath ratio 1∶10,holding time 30 min;in order to ensure homogeneous dyeing,the temperature should be slowly increased to 120℃ after 70℃;The dyeing range of traditional cationic dyes is wider,while dispersed cationic dyes are only suitable for dyeing medium and light colors.
