There are two main methods of fabric printing and dyeing, one is the traditional paint printing and dyeing, and the other is the active printing and dyeing relative to the paint printing.

Reactive dyeing is the dye under certain conditions, the active gene of the dye and the fiber molecules, the dye permeates into the fabric, the dye and the fabric chemical reaction so that the dye and the fiber form a whole paint printing is the dye through the binder and the fabric physical combination of printing and dyeing.

The difference between active printing and paint printing is that the feel of active printing and dyeing is soft, the common saying is that the fabric of active printing and dyeing looks like mercerized cotton, and the printing and dyeing effect is very good from both positive and negative aspects, and the fabric of paint printing and dyeing feels stiff, which looks a bit like the ink painting effect.

1, paint printing and dyeing characteristics

The process is simple and the cost is low. The color fastness is poor, the environmental protection performance is poor once the washing is old, the formaldehyde content is higher than the active printing. The printing part is sticky, and the softening agent is not added. If softener is added, formaldehyde content is higher.

2, the characteristics of active printing and dyeing

Good air permeability, excellent fastness, soft feel, but there are also problems such as cumbersome printing process, long process and difficult processing. Generally, active printing and dyeing can ensure environmental protection and harmless to people, and the feel of color and fabric is also good, and there will be no hard and soft feeling.

3. Identification method

Color recognition: The color of paint printing is not bright, the color is dim, giving a feeling that the color is floating on the cloth. It's like a coat of paint on the wall.

Look at the luster: paint printing cloth before the factory have gone through the "calender" process, so we see the cloth has a shiny feeling, may be paint printing, this through calender finish, is a one-time, will disappear after washing.

Smell: paint printing added a lot of adhesive, not after washing treatment is directly shaped, so there will be a strong taste in the finished fabric.

Touch: paint printing feel hard, fabric manufacturers in order to cover this shortcoming, in the setting of the softener, and the finished product after "calender" feel will be softer, after washing most will fall off.
