Printing And Dyeing Activity Technology

Reactive printing and dyeing is in the dyeing and printing process, the reactive gene of dye and fiber molecules form a combination, so that the dye and fiber form a whole. It makes the fabric with excellent dust-proof performance, high cleanliness and color fastness. Of course, the cost is much higher than dye printing. Is printed with dye reactive dyes, in general, use high viscosity sodium alginate paste do flow (it degeneration, seepage grouting quantity is small, can keep the pattern of the same), mostly adopts double active group M type reactive dyes, the dyes with good fixation rate and the lifting force, at the same time can reduce the soaping color sell prescription / 9 L 'reactive dyes 1 a 2 x x urea resist salt S 10 moderate water alkali agent 15 a 30). Active printing has many advantages over pigment printing, such as good air permeability, excellent fastness, soft hand feel, but there are also problems such as tedious printing process, long process and great processing difficulty.

General reactive printing and dyeing can ensure that environmental protection is harmless to people, color and fabric handle is also better, there will not be a hard a soft feeling.
