牛仔布整理中的电化学漂白

Electrochemical bleaching in the finishing of jeans

简要介绍了氧化漂白工艺、还原漂白工艺、成衣湿处理中的漂白、纺织工业中的电化学工艺和牛仔服的电化学漂白。详细介绍了由DyStar公司和LeopoldFranzens大学首先开发和获得专利的氧化ECB工艺和还原ECB工艺。除漂白浴的再利用外,为了在废水中避免AOX的存在,正在研究基于有机过氧化物的电化学生产的无氯ECB工艺。

The ECB process was developed and patented first of all by DyStar and the Institute for Textile Chemistry and Textile Physics of Leopold Franzens University. Further development of the ECB process then took place in collaboration with partners Tonello srl. and Lilienweiβ textile Dienstleistungen GmbH so that a first prototype could be exhibitd at the ITMA 2003 in Birmingham. Over and above the reuse of bleaching baths in order to avoid AOX in the effluent, chlorinefree ECB processes based on the in situ electrochemical production of organic peroxide compounds have also been investigated. The technological properties of the finished textile as well as economic comparisons are also of particular importance here in addition to the ecological aspects of these processes.
