1. Digital printing
The first is the most common digital printing in life. Digital printing is most commonly used on cotton. It uses reactive dye inks, and a small amount is also applied to hemp, silk, etc., while for chemical fiber digital printing, disperse sublimation dyes are used. Ink production and chemical fiber dispersion direct injection digital. And if it is T/C and other related blended fabrics, you can't use the above methods, but use paint ink for printing. If it is nylon or wool, acid dyes are used for printing.
2. Rotary screen printing
It uses a cylindrical nickel screen with a hollow pattern. After being installed above the circulating rubber guide belt, the color paste will be fed into the net, leaving traces on the bottom of the net. The round net and the guide belt rotate together to make the scraper When scraping and pressing against the flower net occurs, the color paste will be printed on the surface of the fabric through the grid pattern.
3. Flat screen printing
Using the hollow pattern printing mold, fixed on the square frame, the pattern of the mold can penetrate the color paste, and the non-flowered part is closed. When printing, the fabric is pressed tightly through the printing mold, and the color paste is filled on the mold pattern , And repeatedly scrape and press with a spatula to let the color paste through the flower net. However, the production efficiency of this method is extremely low, and it is only suitable for small batch products.
4. Water award printing
This is done by using water-based printing dyes, which are soluble in water, and are evenly printed on the desired position through the mesh of the screen during printing. Commonly used in T-shirt printing.
5. Glue printing
Similar to water slurry printing, but all materials are different. It is a gel-like color that solidifies after drying, and is also commonly used on T-shirts.
6. Flocking printing
Very difficult printing process, only a small amount of printing and dyeing can be done, ordinary printing and dyeing factories generally do not have the process to do it, this printing effect is that the fluff in the fabric is firmed up one by one to form a pattern, like a toothbrush whisker. Therefore it is also called toothbrush flower. Generally the height is about 0.3 cm.
7. Pigment printing
Its pigment is a non-water-soluble coloring substance and has no affinity for fibers. To color the fabric, the coloring must be achieved by the coating of the film-forming polymer compound and the adhesion to the fiber. This kind of printing has a wide range of applications, whether it is blended or interwoven, and the process is relatively simple. But the effect will cause the fabric to feel poorer.
8. Discharge printing
It is dyed with dyes that are not resistant to discharge agents, dried, and then printed with color dye printing pastes containing discharge agents or at the same time. In the post-processing, the dye of the printing dye is destroyed, and then a white pattern is formed. It is often used for washing effect, which is more common in denim fabrics.
