非水介质活性染料染色关键技术体系及其产业化研究进展

为实现活性染料对棉纺织品等亲水性纤维的无盐、高固色率和污水零排放染色加工,首先分析了传统水浴染色体系亟需解决的问题;其次对现有少水/无水染色加工技术进行总结,认为现有的活性染料新型染色加工技术没有从根本上解决耗水量大、污水排放量大的问题;在此基础上,分析了硅基非水介质染色关键技术体系的原理和发展现状,并进一步介绍了非水介质染色及其适用性和介质的基本要求,棉纤维在非水介质染色体系中的染色性能、产业化推广等;最后,对非水介质染色技术进行总结和展望,认为非水介质染色关键技术不仅解决了棉纺织品染色高污染、高排放的问题,且染色的能耗及成本得到了进一步降低。

Technology progress and application prospect of non-aqueous medium dyeing systems

In order to achieve dyeing of hydrophilic fibers such as cotton textile with reactive dyes with salt-free,high fixation rate and zero sewage discharge,the problems call for urgent attention in traditional water base were firstly reviewed and analyzed.As the second step review,the less water/water-free dyeing technologies were summarized.The results revealed that these new dyeing technologies of reactive dyes have yet solved the problems of large water consumption and large discharge of wastewater.On this basis,the reactive dyeing in silicone non-aqueous dyeing system was reviewed,including the definition and serviceability of dyeing in non-aqueous medium,the basic requirements of dyeing medium,and further introduced the concept of non-aqueous medium dyeing.The applicability and basic requirements of the medium,the dyeing performance of cotton fiber in non-aqueous medium dyeing system,and the industrialization development were introduced.Finally,the dyeing technology of non-aqueous medium was summarized and prospected.It is believed that the key technology of non-aqueous dyeing would not only solve the problems of high pollution and high emission of cotton textile dyeing,but also the energy consumption and cost of dyeing have been further reduced.This dyeing technology is expected to change the image of serious environmental pollution in the traditional dyeing industry,and to lead to a clean production and sustainable development for textile dyeing.
