What is flocking printing?

　　If you want to understand what is flocking Yinhua, let's put it simply, it is actually specifically for the fiber fluff of the fiber short fleece. As for other materials and fabrics, flocking printing is not used, so the combination of fiber fluff and fiber short fleece is a printing method that is attached to the surface of the fabric according to a specific pattern.

　　Then with the rapid development of electronics, fiber, chemical, machinery and other industries, the quality of flocking cloth continues to improve, and the use continues to expand, starting from industrial fabrics and decorative fabrics. Gradually developed into the field of clothing fabrics, in recent years, the development has been extremely rapid, more and more new varieties have been developed, and many printing and dyeing methods have been applied to flocking fabrics. Such as paint printing, bronzing printing, printed cloth flocking, and direct printing and drawing on flocking cloth, dye printing. The application of these methods makes cloth flocking products more abundant and adds a beautiful landscape to the clothing industry.

　　To perform various printings on flocked cloth, it is necessary to have a more comprehensive understanding of the structure and performance of flocked cloth.

　　Let's talk about the main characteristics of flocking printing process. What kind of process is flocking printing? Flocking technology is more and more widely used, and it has the footprint of flannel in the fields of decoration, automobiles, hotels, hall wall panels, clothing, and apparel. The flocking market in the future has very broad prospects and far-reaching social benefits. The flocking process is more complicated. Understand the flocking process, learn the two processes of flocking fabric and flocking printing.

　　Flocking cloth is a product that uses high-voltage electrostatic field to grow short fibers on gray cloth, that is, printing adhesive on the surface of the substrate, and then uses a certain electrostatic field voltage to accelerate the planting of short fibers to the adhesive and coat the gray cloth. In this way, the flocking cloth required by the flocking process is formed.

　　If you are making flocking cloth, you generally need to pay attention to two points, one is the choice of fluff, and the other is the adhesive. Commonly used fluff includes viscose fiber and nylon fiber. Viscose has low degree of polymerization, low fiber strength, low dosage, and does not soften or melt at high temperatures. Nylon fiber has good elasticity, abrasion resistance and durability, but it will turn yellow and soft under high temperature. When printing, choose the appropriate fluff according to the actual situation.

　　Adhesives are also divided into two types, one is a cross-linking adhesive and the other is a self-crosslinking adhesive. When using diplomatic joint glue, add a certain amount of cross-linking agent and catalyst, but it must be used immediately after preparation, especially after adding the catalyst, it should not be left for too long, otherwise the cross-linking temperature will occur at room temperature and affect its use. This is what you need to pay attention to during the operation. Self-crosslinking adhesives have a longer effective storage time. If a small amount of crosslinking agent is added during use, increasing the depth of crosslinking is more conducive to improving the fastness of flocking.

　　In addition to the difference between fluff and adhesive when flocking, attention should be paid to the choice of baking temperature and time. If the temperature and time are not set properly, it may cause some hair loss.

　　Flocking printing

　　The flocking printing process is roughly divided into direct printing and discharge printing, such as denim flocking, transfer flocking and so on.

　　Direct printing Direct printing is generally carried out on a flat screen or rotary screen printing machine. Choose different printing methods according to the requirements of the pattern. Generally, direct printing will not choose discharge printing.

　　Discharge printing The discharge printing process is more complicated. Discharge printing is divided into white discharge and color discharge. Discharge whitening is the use of reducing agent to destroy the dye chromophore on the flocked fabric, so that the fluff is restored to its original state; At the same time, it destroys the dye structure on the dyed fluff to achieve the purpose of discharge printing.

　　Flocking technology has not developed for a long time, but it has developed rapidly. From the expansion of flocking cloth to the diversification of flocking methods, flocking technology has opened up new areas.
