10 Traditional Printing Processes Of Pigment Printing Fabric

10 traditional printing processes of Pigment Printing Fabric :

1. The water slurry printing process is the most basic printing process in the screen printing industry. It can be printed on almost all light-colored fabrics such as cotton, polyester, linen, etc., and is widely used. It works similar to dyeing, except that it "dyes" an area of ​​the fabric to the desired color for the flower position. Therefore, this process cannot be applied to dark-colored fabrics.

2. The mucilage printing process applies a special chemical gel and the dyestuff is highly seamlessly mixed. The dye is firmly attached to the fabric through the medium of the gel, and the glue printing process overcomes the limitations of water-based printing. Its characteristics are that it is suitable for printing of various color depths and materials. It can be printed on cotton, linen, viscose, polyester, nylon, polypropylene, vinyl, and various fiber-blended fabrics.

3. Foam printing is also known as three-dimensional printing. The foam printing process is developed on the basis of the mucilage printing process. Its principle is to add a certain proportion of chemical substances with a high expansion coefficient to the mucilage printing dye. After the printing position is dried, it is foamed at a high temperature of 200-300 degrees to achieve a three-dimensional effect similar to "relief".

4. The electrostatic flocking printing process is one of the three-dimensional printing processes. The principle is to transfer the high-strength compound resin adhesive brightener to the surface of the substrate with a screen containing the desired pattern, and then charge the fiber fluff through a high-voltage electrostatic field of hundreds of thousands of volts. Make the fluff "hit" vertically and evenly on the adhesive, "lay" a layer of fluff on the surface of the fabric, and then cure it at a high temperature.

5. Photochromic printing is also known as photochromic printing. The early photochromic printing used photochromic dyes. Under the irradiation of ultraviolet rays, the structure of the dyes changed, showing different colors. For example, dye A is colorless. After being irradiated by ultraviolet light, the molecule opens into a dye B with a cyanine structure, which is blue. When dye B is exposed to visible light, it will re-convert to a colorless dye A.

6. Thermochromic printing is also called thermochromic printing. The early thermochromic printing has been processed into microcapsules with thermochromic dyes, and then printed on the fabric. It has two types: reversible and irreversible. Irreversible thermochromic dyes are generally used as temperature detection indicators. It is generally reversible when used in textiles. According to its structure, it can be divided into inorganic and organic categories. Organic thermochromic dyes are widely used in textiles. They are composed of leuco dyes, color developers, and sensitizers (desensitizers).

7. The water-changing printing process is the latest printing process. Using a variety of physical and photochemical principles, products are produced by this process. When the fabric enters the water, the raw materials and water on the fabric undergo instantaneous complex changes, presenting a rich preset pattern. When the water on the surface of the fabric evaporates, the original pattern appears again.

8. The fluorescent printing process is a new type of special printing process. The principle is to use a special process to integrate the photo-storage self-luminous material into the fabric, and realize the automatic light-emitting function by absorbing all kinds of visible light. Its characteristic is that it can be cycled infinitely use.

9. The principle of the fragrance printing process is to use liquid fragrance or other organic solution so that the fragrance can be uniformly mixed with the colored printing dope slurry and fixed on the fabric by the action of the adhesive in the coating. Because the organic components contained in the essence are many, volatile and chemically unstable compounds, the composition of the essence is very complex, and it is easy to volatilize and lose or decompose and deteriorate during use and storage.

10. Hot stamping and silvering is a traditional means of beautification and beautification and is often used in many paper packaging, while silk-screening, hot stamping, and silvering is a new processes. The principle is to add special chemicals to the printing paste to make the flower position appear. It produces a particularly beautiful gold and silver color, and the color sample is durable and does not fade. It can be printed on many kinds of fabrics, and the cost is lower than that of the traditional process. It is a very ideal printing and decoration process.
