How do We Distinguish Reactive Printing and Dyeing from Coating Printing and Dyeing?

There are two main methods of cloth printing and dyeing: traditional coating printing and dyeing and reactive printing and dyeing.

How do we distinguish them?

Reactive printing and dyeing means that the active gene of dye is combined with fiber molecules in the process of dyeing and printing, which makes the dye and fiber become a whole. It makes the fabric with excellent dustproof performance, high cleanliness and high color fastness. Of course, the cost is much higher than that of coating printing and dyeing. Azo, formaldehyde and harmful substances are not added in the printing and dyeing process. The fabric does not fade or shrink when washed.

The difference between the two is that the fabric after reactive printing and dyeing feels soft and looks like mercerized cotton. The printing and dyeing effect is very good from both sides. The fabric after coating printing and dyeing feels stiff and looks a bit like an ink painting.

Characteristics of Coating Printing and Dyeing

Its process is simple with low cost. The color fastness of the fabric is poor, which will become older every time it is washed. It has poor environmental protection performance. Formaldehyde content is higher than reactive printing and dyeing. The coating part is sticky, which appears hard without adding softening agent. If softening agent is added, the formaldehyde content will be higher.

Characteristics of Reactive Printing and Dyeing

The fabric has good air permeability, excellent fastness and soft hand feeling. However, there are some problems such as tedious printing process, long process and difficult processing. Generally, reactive printing and dyeing can ensure environmental protection and harmlessness. The printing and dyeing parts and fabrics have good and uniform hand feeling.

How do we distinguish reactive printing and dyeing from coating printing and dyeing?

See color:

The color of coating printing and dyeing is dull. It feels like the color is floating on the cloth. It is like the painting on a wall.

See gloss:

Coating printed fabrics go through the "calendering" process in the factory, so everyone can see that the cloth with shiny surface may be coating printing. The finish obtained by calendering is disposable and will disappear after washing.

Smell odor:

A lot of adhesives are added in coating printing and dyeing. The fabric is directly shaped without washing, so it will have a strong smell.

Feel texture:

Coating printing has a hard hand feeling. In order to cover this shortcoming, the cloth distributors add softening agents when setting. The finished products will feel softer after calendaring. But most of the softening agents will fall off after being washed with water.
