芳砜纶纤维的阳离子染料染色

Cationic dyeing of polysulfone fiber

以较小配伍值的阳离子染料对芳砜纶纤维进行载体染色,优化染色工艺为:阳离子染料0.5%owf,促染剂NaCl 50 g/L,载体MS 40 g/L,非离子渗透剂1 g/L,pH值3,浴比1:12,染色温度135℃,时间60 min。采用阳离子染料染色的芳砜纶纤维色牢度较好,均在4级左右。

Carrier dyeing of polysulfonamide fiber was carried out with selected cationic dyes which had small compatible values. Optimum process was deined as follows： cationic dye 0.5%owl, a promoter NaCl 50 g/L, carrier MS 40 g/L, non-ionic penetrating agent 1 g/L, pH value 3, ratio 1 ： 12, dyeing at 135 ℃ for 60 minutes. The dyeings featured 4-level color fastness.
