活性染料染色牢度对策和固色剂的发展(待续)

Reactive dye fastness countermeasures and development of fixing agent(to be continued)

近几年,根据商检和海关统计,环保不合格的纺织品和服装,染色牢度不合格占了50%以上.特别是浅色织物的耐光牢度和汗光牢度,主要决定于染料和深浓度织物的湿处理牢度和湿摩擦牢度.前者完全是染料所引起,后者除染料以外,染整加工过程和固色剂也会导致染色牢度不合格.实际上,市场上供应的固色剂真正有效果的不多,针对这类固色剂的发展进行探讨.真正要解决染色牢度的是染料本身,助剂仅助一臂之力,不要对助剂有过高的奢望.染料企业必须提供1/72,1/25和6/1,8/1国家标准染料深度色卡,不要单一的1/1色卡,给染料下游用户选用染料一个方便.

In recent years, according to inspection and customs statistics, color fastness accounted for more than 50% of environmental unqualified textiles and garments, especially light fastness and perspiration light fastness of light-colored fabric. The color fastness failure rate mainly depends on the wet fastness and wet rub fastness of dyes and deep color fabric. The former is entirely caused by the dye, the latter derived from the dye, dyeing and finishing process and the fixing agent. In fact, a few fixing agents in the market has much effect. The development of such fixing agents was discussed. Dye itself is the first problem to be solved to improve the color fastness, the assistant is only the second problem and do not place much hope on it. The dye industries must provide 1/72, 1/25 and 6/1, 8/1 national standard dye depth color card, not sin- gle 1/1 color card in order to provide the dye downstream users convenience for dye selection.
