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 as opposed to paint printing and dyeing.

Reactive printing and dyeing is the dye under certain conditions, the active gene of the dye is combined with the fiber molecule, the dye penetrates into the fabric, and the chemical reaction between the dye and the fabric makes the dye and the fiber form a whole; pigment printing and dyeing is the physical combination of the dye and the fabric through the adhesive printing method.

The difference between reactive printing and dyeing is that the feel of reactive printing and dyeing is smooth and soft. The common saying is that the fabric of reactive printing and dyeing looks like mercerized cotton, and the effect of printing and dyeing is very good from both sides; while the fabric of paint printing and dyeing feels stiff. It looks a bit like an ink painting effect.

1. Characteristics of paint printing and dyeing

The process is simple and the cost is low. The color fastness is poor, and it is old once washed; the environmental protection performance is poor, and the formaldehyde content is higher than that of reactive printing and dyeing; the printing part is sticky, and it appears hard without adding a softener. If softener is added, the formaldehyde content will be higher.

2. The characteristics of reactive printing and dyeing

It has good air permeability, excellent fastness and soft hand feeling, but there are also problems such as cumbersome printing process, long process and difficult processing. Generally, reactive printing and dyeing can ensure environmental protection and harmlessness to people, and the color and fabric feel better, and there will be no hard or soft feeling.

3. Identification method

Recognition of color: The color of pigment printing is not bright and dull, giving people a feeling that the color is floating on the cloth. It's like putting a coat of paint on the wall.

Look at the gloss: Pigment printed fabrics have undergone a "calendering" process before leaving the factory, so everyone sees a shiny feeling on the cloth surface, which may be pigment printing. The smoothness obtained by calendering is one-time. After washing will disappear.

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

Hand feeling: Pigment printing feels hard. In order to cover up this shortcoming, fabric manufacturers add a softener when setting the shape, and the finished product will feel softer after "calendering", and most of it will fall off after washing.
