真丝绸接枝及阳离子染料染色工艺探讨

Grafting and Cationic Dyeing of Real Silk Fabrics

以对氨基苯磺酸、三聚氯氰及间 β-羟乙基砜硫酸酯苯胺为原料 ,合成了带有双活性基团及磺酸基的阴离子接枝剂。真丝绸经该接枝剂处理后 ,用阳离子染料进行染色 ,可提高上染百分率及染色牢度 ,而对阴离子染料有一定的阻染效果。

Real silk fabrics are grafted with bireactive radicals and sulfonic groups containing cationic grafting agent synthesized with sulfanilic acid, cyanuric chloride and m_β_hydroxyethyl sulfone aniline sulfate, and then dyed with cationic dyes. It is found that such processes can improve dye_uptake and colour fastness, with blocking effects on anionic dyes.
