Classification of Fabric Printing (Part I)

  1. Tropical Printing: first, print the pigment on the paper to make the transfer printing paper, and then transfer the color to the fabric through high temperature (heating and pressing on the back of the paper). It is generally used for chemical fiber fabrics. It is characterized by bright colors, fine layers, realistic patterns, and strong artistry. The transfer printing process is simple, the investment is small, the production is flexible, and the price is a little high, but it has a certain grade.
  2. Discharge printing: use a dye that is not resistant to the discharge agent to dye the ground color. After drying, use a fancy dye printing paste containing a discharge agent or both. During post-treatment, the ground color dye at the printing place is destroyed and faded, forming a white pattern on the color ground or a color pattern formed by dyeing with the fancy dye. Also known as white or color pulling. Can it make clothes look like they have been washed? The color of the clothes seems to have been washed away. It is mottled. In fact, this is a pull-out printing. The principle of pull-out printing is to pull out the color of the fabric tissue fiber to make it become another lighter color, which is more like the washing effect.
  3. Rotten print: this process uses the difference in chemical corrosion resistance of different fibers in the interwoven or blended fabrics, and applies a burning agent to remove one of the fibers locally in the fabric through the printing method, leaving other fibers to form a translucent pattern.
  4. Wrinkle printing: the chemicals that can make the fiber expand or shrink are locally applied to the fabric by the printing method. Through appropriate treatment, the fibers at the printed part and the fibers at the nonprinted part will swell or shrink, so as to obtain the products with regular concave-convex patterns on the surface. Such as pure cotton printed seersucker with caustic soda as an expansion agent. Also called bump printing.
  5. Flat-screen printing: the printing die is a polyester or nylon screen (pattern) fixed on the square frame and with a hollow pattern. The pattern on the pattern plate can penetrate the color paste, and the nonpattern part is closed with a polymer film. During printing, the pattern plate presses the fabric tightly, and the pattern plate holds the color paste, which is scraped and pressed back and forth with a scraper to make the color paste reach the fabric surface through the pattern. Flat-screen printing has the advantages of low production efficiency, wide adaptability, and flexible application. It is suitable for small batch and multi-variety production.
  6. Round screen printing: the printing die is a cylindrical brocade screen with a hollow pattern, which is installed above the circulating rubber guide belt in a certain order and can rotate synchronously with the guide belt. During printing, the color paste is input into the screen and stored at the bottom of the screen. When the round screen rotates with the guide belt, the scraper is tightly pressed on the bottom of the screen and the flower net generates relative scraping and pressing, and the color paste reaches the fabric surface through the pattern on the screen. Circular screen printing is a continuous process with high production efficiency. It has the advantages of roller and flat-screen printing, but it has some limitations in the fineness of patterns and the intensity of printing color.
  7. Pigment printing: also known as pigment printing, because the pigment is a non-water-soluble coloring substance and has no affinity for the fiber, its coloring must be realized by the coating of a high molecular compound (adhesive) that can form a film and the adhesion to the fiber. Pigment printing can be used for the processing of any fiber textile. It has more advantages in the printing of blended and interwoven fabrics. It has a simple process, wide chromatography, and clear flower shape outline, but poor hand feeling and low rubbing fastness.
