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 is a kind of content. Reactive type The cationic prepolymer of functional groups can change various kinds. Fiber material The new type of textile auxiliaries for the adsorption and reactivity of dyes, the reactive groups reaction of cotton fibers and colored media after the treatment of color media, so that cotton fibers are introduced into cationic dye holders, and the anionic dyes in the solution will rapidly absorb and firm with cationic dyes.

Benefit evaluation:

Low pollution, low energy consumption and low water consumption.
