There are two main methods of fabric printing and dyeing. One is traditional coating printing and dyeing, and the other is reactive printing and dyeing relative to coating printing.

Reactive printing dyeing is to combine the reactive genes of dyes with fibromolecules during the dyeing and printing process, so that dyes and fibers form a whole. Make the fabric's dustproof performance, high degree of cleanliness, and high coloring. Of course, the cost is also much higher than the pigment dyeing. During the printing and dyeing process, it does not add puppet nitrogen and formaldehyde.

The difference between reactive printing and dyeing and coating printing is the smooth feel of reactive printing and dyeing. The general saying is that the fabric of the reactive printing and dyeing looks like a light cotton. It looks a bit like ink painting effect.

 

Features of coating printing and dyeing

Simple craftsmanship and low cost. Poor the color fastness, once washed once; the environmental performance is poor, the formaldehyde content is higher than the reactive printing and dyeing; If the soft agent is added, the formaldehyde content is higher.

 

Features of reactive printing and dyeing

It has good breathability, excellent fastness, and soft feel, but there are also problems such as cumbersome printing process, long process and difficulty in processing. Generally, reactive printing and dyeing can ensure that environmental protection is harmless to people, and the feel of color and fabric is also better. There will be no hard feeling.

 

How to distinguish reactive printing and coating printing and dyeing?

 

Color

The color printing color is not bright, and the color is dim, giving a color that floats on the cloth surface. It's like brushing a layer of paint on the wall.

 

Gloss

The coating printing fabric has passed the "light" process before leaving the factory, so everyone saw that the cloth surface has a kind of oily feeling, which may be the printing of the coating. Essence

 

Smell

The coating printing adds a lot of adhesives, and it is directly shaped without washing treatment, so the finished fabric will have a strong flavor.

 

Feel

The coating printing feels hard. In order to cover this shortcoming, the fabric dealer adds a soft agent during the setting, and the finished hand feels softer after the finished product is "rolled". Most of them will fall off after washing.
