摘要

活性染料是纤维素纤维染色中最常用的染料。在染色液中加入大量的中性盐和碱来固定染料,这是最常用的技术方法。尽管如此,10-40%的染料没有固定在棉花上,与盐一起,对水道构成了巨大的环境负担。最近,人们研究了提高这些染料的物质和反应性的方法,目的是促进更经济、更环保的工艺。从这个意义上说,棉花的阳离子改性可以被认为是一种有前途的方法,可以提高活性染料的利用率。本文综述了不同阳离子剂在棉花加工中的应用可能性,以及阳离子改性对活性染料染色能力的影响。

Influence of cationic modification of cotton on dyeing with reactive dyes
Reactive dyes are the most popular dyes for dyeing cellulose fibers. The exhaustion method is the most common technical method of their application, when large amounts of neutral salts and alkali are added to the dyeing bath to fixing the dyes. Despite this, 10-40% of the dye is not fixed to the cotton and together with the salts, it represents a large environmental burden for watercourses. Recently, methods have been studied to increase the substantiality and reactivity of these dyes with the aim of promoting procedures that are more economical and environmentally safer. In this sense, cationic modification of cotton can be considered a promising procedure for increasing the utilization of reactive dyes from the technological solution. This review paper reports on the possibilities of applying different cationic agents for cotton processing and the effects of cationic modification on the ability to dye with reactive dyes.
