Reactive Printing And Dyeing And Paint Printing And Dyeing

There are two main methods of fabric printing and dyeing, one is traditional paint printing and dyeing, and the other is reactive printing and dyeing, which is opposite to paint printing and dyeing. Reactive printing and dyeing is a dye that penetrates into the fabric under certain conditions, and the dye and fabric react chemically to form a whole with the dye and the fiber; paint printing and dyeing is a dyeing method in which the dye is physically combined with the fabric through an adhesive.

Features of reactive printing and dyeing:

No azo and formaldehyde are added during the printing and dyeing process, and it does not contain harmful substances to the human body. It is healthy and safe, and it looks like new after long washing and is not easy to fade. Its process determines that the price is relatively expensive.

Features of paint printing and dyeing:

The process is simple and the cost is low. The color fastness is poor, and it becomes old after each washing; the environmental performance is poor, and the formaldehyde content is higher than that of reactive printing and dyeing; the printed part is sticky, and it appears harder without adding softener. If softener is added, the formaldehyde content is higher.

4 ways to identify reactive printing

1. Look at the color:

The color of the paint printing is not bright, the color is dull, and it gives people a feeling that the color is floating on the cloth.

2. Look at the gloss:

Coating printed fabrics are all “calendered” before leaving the factory, so if you see a glossy feeling on the fabric, it may be coating printing. This glossiness obtained by calendering is one-time and will disappear after washing.

3. Smell:

Coating printing adds a lot of adhesives and is directly shaped without washing, so there will be a strong smell in the finished fabric.

4. Touch the feel:

Coating printing feels hard. In order to cover this shortcoming, fabric manufacturers add softeners during shaping, and the finished product will feel softer after “calendering”. Most of it will fall off after washing, and the final prototype will be exposed.
