What are the common printing methods?
1. Transfer printing: firstly print the pigment on paper, make transfer printing paper, and transfer the color to the fabric through high temperature. It is generally used in chemical fiber fabrics. It is characterized by bright colors, delicate layers and vivid patterns. It is artistic, but the process is currently only applicable to clothing made of a few synthetic fibers such as polyester. The transfer printing process is simple, the investment is small, and the production is flexible. It is currently popular in the market. This transfer printing and other types of printing are compared, the price is higher, but there is a certain grade.
2. Discharge printing: dyeing the color of the dye that is not resistant to the dyeing agent, after drying, printing with the dye dye containing the discharge agent or the dyeing agent at the same time. Destructive and achromatic, forming a white pattern on the ground or a colored pattern formed by dyeing the flower dye. Also known as white or color pull.
3. Reduced printing: This process utilizes the difference in chemical resistance of different fibers in the interlaced or blended fabric. The stripping agent is applied to remove one of the fibers in the fabric by a printing method, and the other fibers are retained to form a translucent pattern. Also called burn-out printing or burnt-out printing.
4. Shrinking printing: a chemical applied to the fabric to locally expand or shrink the fiber by a printing method, and by appropriate treatment, the difference between the fiber of the printing part and the fiber of the non-printing part is expanded or contracted, thereby obtaining regular irregularities on the surface. Flower-shaped products. A cotton printed seersucker such as caustic soda as a bulking agent. Also called concave and convex printing.
5. Flat screen printing: The printing mold is a polyester or nylon screen fixed on a square frame and having a hollow pattern. The pattern on the flower plate can pass through the color paste, and the pattern without the pattern closes the mesh with a polymer film layer. When printing, the stencil presses the fabric, and the stencil is colored with a squeegee, and is scraped back and forth with a doctor blade to make the color paste pass through the pattern to reach the surface of the fabric. The flat screen printing has low production efficiency, but has wide adaptability and flexible application, and is suitable for small batch and multi-variety production.
6. Rotary screen printing: The printing mold is a cylindrical nickel-skin screen with a hollow pattern, which is installed in a certain order above the rubber belt of the circulating operation and can rotate synchronously with the conduction belt. When printing, the color paste is input into the net and stored at the bottom of the net. When the round net rotates with the guide belt, the scraper and the flower net which are pressed against the bottom of the net are relatively scraped, and the color paste reaches the circular surface of the fabric through the online pattern. It belongs to continuous processing, has high production efficiency, and has the advantages of roller and flat screen printing, but it has certain limitations in the fineness of the pattern and the richness of the printing color. Remember: the choice of rotary screen printing in color and color has certain limitations.
7. Pigment printing: Also known as paint printing, since the pigment is a water-insoluble coloring matter, it has no affinity for fibers, and its coloring is achieved by coating of a polymer compound (adhesive) capable of film formation and adhesion to fibers. Pigment printing can be used for the processing of any fiber textile. It has superiority in the printing of blended and woven fabrics. The process is simple, the chromatogram is wide, the flower shape is clear, but the hand feel is not good and the rubbing fastness is not high.
8. Water printing
The so-called water slurry is a kind of water-based slurry, which is suitable for printing on light-colored clothing fabrics. It is a kind of printing type which is relatively wide. But it also has an advantage, because it does not affect the original texture of the fabric, so it is more suitable for large-area printing patterns. Features soft touch, bright color ~ ~ But the water slurry has a major drawback is that the color of the water slurry is lighter than the cloth color ~ ~ cloth color is deep, the water can not cover.
9. Glue printing
The appearance of the glue and its wide application in the water slurry, because of its very good coverage, can also print any light color on the dark clothes, and have a certain degree of gloss and three-dimensional, making the garment look more upscale So, it has been rapidly popularized and will be used on almost every printed T-shirt. However, because it has a certain hardness, it is not suitable for large-area solid patterns. Large-area patterns are best printed with water-based paste, and then embellished with some glue, which can solve the problem of large-area glue and highlight patterns. The layering; there is also a way to sneak a large area of the field pattern into a rotten effect, but it is always hard to wear, so it is better to solve the problem of large-area printing by combining water and glue. . It has a smooth and matte finish and is soft, thin and environmentally friendly. It can be stretched.
10. Ink printing
The ink is not very different from the glue at first glance, but when the glue is printed on a smooth fabric such as a windbreaker, the color fastness is generally poor, and it can be scraped off with a strong scratch, but the ink can overcome this disadvantage. Therefore, when making windbreakers, it is generally printed with ink. The characteristics are bright and vivid, and the image is realistic. The market has seen a wave of human head printing some time ago. I know that everyone pays attention to it, so the clear and ultra-realistic printing is generally only ink printing. In order to print out such effects, sometimes you can also sprinkle some gold powder and silver powder on the ink, and feel the decorative effect is better.
Glue: Glue is to be molded, it is pressed, not printed. Flocking: soft to the touch, bright colors, but the water will fall off. If you want to wash, you must first fix the toner.
Foaming: Printing with a microsphere foaming ink on a paper or fabric by screen printing, heating to obtain a embossed graphic or blind reading.
Foaming printing is a printing method in which the fiber is exposed to a bulking agent and the length is shortened, and the fabric part and the base fabric are differently physically changed, and an uneven pattern is formed on the surface of the fabric. Its product is called seersucker. There are bubbles on the surface of the fabric, so that it is not close to the body when worn, and has a cool feeling. It should be used as children's clothes, clothes, dresses, pajamas, etc.; the thicker seersucker yarn can make bedspreads, curtains, etc.
The seersucker is divided into weaving seersucker and alkali-shrinking bubble yarn according to the principle of forming bubbles. According to different printing and dyeing methods, it is divided into dyed seersucker, printed seersucker and yarn-dyed seersucker. Most of the weaving seersucker yarns are color-dyed color strips, which are all cotton, and also have a blend of purified fiber or chemical fiber. The variety replacement is more troublesome. The alkali shrinkage yarn is produced by the foaming printing process. Therefore, the pattern cloth is limited to the strips, and the variety of colors is rich. The raw materials are all cotton or synthetic fibers. Compared with the weaving of the seersucker, the process is simple, and the printing and foaming can be completed at one time. And can be alternated with the printing process, can produce a variety of effects.
Foaming printing process: There are basically two kinds of processes in foaming printing: one is to use cotton fiber to expand with thick alkali, the diameter is increased, and the length is shortened. The caustic soda is printed directly on the cotton fabric, and the cotton at the pattern is printed. The fiber shrinks and the non-pattern is foamed. The so-called bubble yarn is called alkali bubble; the other is to print the anti-alkali pulp on the cotton fabric, and then pad the alkali liquor, the non-pattern shrinks, the pattern is foamed, A fading colored bubble pattern.
Gel slurry: It's the same as jelly. It's sticky, sticky, and it's easy to get into the fabric!
Hot stamping: A transparent adhesive is printed on the surface. It is pressed with gold foil paper or other colored foil paper at high temperature. The factory's lack of skill may affect the washing!
Suede pulp: It is a kind of slurry, which can be done by flocking, such as small details! The effect is finer than flocking, but the texture is not flocked!
