改性剂预处理对活性染料固色率的影响

Influence of Modifier Pretreating on Reactive Dyes Fixation

采用三种不同类型的改性剂对粘棉混纺织物进行预处理,探讨了织物经反应型和非反应型阳离子化助剂改性后,对活性染料固色率的影响。结果表明,用反应型阳离子化助剂进行预处理,可以明显提高活性染料的固色率,降低电解质的用量,非反应型助剂预处理后的效果不明显。

Rayon/cotton blended fabric was pretreated by three kinds of modifiers. Effects of modification on fixation yield of reactive dyes with reactive and non-reactive cationic modifiers were investigated. Results indicate that after pretreating with reactive modifiers,the fixation yield is increased ,and the volume of electrolytes is reduced.
