The Reactive Technology Of Printing And Dyeing

Reactive printing and dyeing are also called reactive dyes.

It contains active groups that can react with fiber molecules.

In the process of dyeing and printing, reactive groups of dyes and fiber molecules form a bond, so that the dye and fiber form a whole.

The fabric has excellent dustproof performance, high cleanness, and no fading after long washing.

There are two main methods of cloth printing and dyeing, one is the traditional paint printing and dyeing, and the other is the reactive printing and dyeing relative to the paint printing and dyeing.

Reactive printing and dyeing is in the process of printing and dyeing do not add azo and formaldehyde, do not contain harmful substances to the human body, and do not fade or shrink when washing.

The difference between reactive printing and dyeing and coating printing and dyeing is that the feel of reactive printing and dyeing is smooth and soft. The common saying is that reactive printing and dyeing fabrics look like mercerized cotton, and the printing and dyeing effect is very good from both positive and negative aspects.

And the paint - dyed fabric feels stiff and looks a bit like ink painting.

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
