活性染料无盐低盐染色研究进展

摘要

Large amounts of salts put in dyeing of reactive dyes as accelerant wil lead to environmental pol ution. Thus salt- free and low- salt dyeing has become a hot research issue. Research development of salt- free and low- salt dyeing for reactive dyes were ful y discussed in four aspects: (1) developing new reac-tive dyes through changing of reactive group; (2) increasing dye adsorption by fiber modification; (3) developing alternative of novel dyeing auxiliaries and sa(4) designing reasonable and novel dyeing process.%活性染料染色需加入大量的盐促染，导致环境污染。因此，无盐低盐染色成为当前研究的热点。从4方面综合分析了活性染料低盐无盐染色的研究进展：(1)改变反应基团，开发新型活性染料；(2)对纤维改性，提高对染料的吸附能力；(3)开发新染色助剂和盐的替代物；(4)制定合理的染色工艺，开发新型染色工艺。
