New Technology Of "Salt Medium" Without Salt And Alkali Dyeing

Our country Printing and dyeing industry Wastewater pollution is becoming more and more serious, and environmental protection pressure is increasing. The development of clean production technology is imperative. Guangdong de Mei fine chemical company Limited by Share Ltd organization technical tackling group has carried out nearly 3 years of research on clean dyeing process, principle, new modifier development, application evaluation and so on, and has made breakthrough progress. At present, the project applies for "China's invention patent" with "a modified fiber production method and its environment-friendly dyeing process (color media dyeing)", which is also an original invention of independent intellectual property rights in China's printing and dyeing cleaner production.

　　 Color media It is a cationic prepolymer containing reactive functional groups, which can change the new textile auxiliaries of various fiber materials adsorbing and reacting to dyes. The reactive reaction of cotton fibers and colored media after color media treatment leads to the introduction of cationic dyes to cotton fibers, and the anionic dyes in the solution will absorb and bind rapidly with cationic dyes.

　　 benefit Evaluation:

Low pollution, low energy consumption and low water consumption.
