There are two main methods of fabric printing and dyeing. One is traditional coating printing and dyeing, and the other is active printing and dyeing relative to coating printing.
Active printing and dyeing is a dye under certain conditions, the active genes of dyes are combined with fiber molecules, and dyes penetrate into the fabric. The chemical reactions of dyes and fabrics cause the dye and fiber to form a whole. Printing and dyeing method.
The difference between active printing and dyeing and coating printing and dyeing is the smooth feel of active printing and dyeing. The general saying is that the fabric of the active printing and dyeing looks like a light cotton. It looks a bit like ink painting effect.
1. Special point of coating printing and dyeing
Simple craftsmanship and low cost. Poor the color fastness, once was washed once; the environmental performance is poor, the formaldehyde content is higher than the active printing and dyeing; the printing area is sticky, and the soft agent is harder without the soft agent. If the soft agent is added, the formaldehyde content is higher.
2. The characteristics of active 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, active 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.
3. Different ways
Conscious color: The color of the coating print 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.
Look at gloss: The coating printing fabric has undergone the "light" process before leaving the factory, so everyone can see that the cloth surface has a kind of bright feeling, which may be the printing of the coating. It will disappear.
Smell: The coating prints add a lot of adhesives, and it is directly shaped without washing treatment, so there will be a strong taste in the finished fabric.
Touching the feel: The coating printing feels hard. In order to cover this shortcoming, the fabric dealer adds a soft agent during the setting, and the feel will feel softer after the finished product is "rolled". Most of them will fall off after washing.
