A water slurry Printing Process Water paste printing process is a kind of silk screen printing industry, the basic printing process, which can be cotton, polyester, linen, etc., almost all of the light background fabric printing, is widely used. It works similar to staining, the difference is the fabric of a region is to "dye" into the flower-bit color required. Therefore, this process can not be in the deep background material on the application. Water paste printing process of the biggest advantages is widely used to spend a good bit fastness, can use relatively inexpensive price printed good results. The limitations of printing process water slurry is not all dark fabrics on the application.
II Glue Printing process Paste printing process application of chemical special seamless gel mixed with a high degree of dye. The role of dye through the gel medium, solid attached to the fabric, the glue printing paste printing process to overcome the limitations of water. Its characteristics are to adapt to a variety of color depth and printed material, it can be cotton, linen, viscose, polyester, nylon, polypropylene, polyvinyl chloride fiber and various fiber blended fabric printing, but also in leather, artificial leather and other materials printing, it can be carried out with fluorescent printing, inkjet printing, Burnt-out printing, electrostatic printing and flock printing process. Paste printing process of the biggest advantages is the wide range of applications, color beautiful, restored high, but its water slurry production process is relatively complex printing process, the cost is relatively high.
Glue the emergence and widely used in water slurry, due to its coverage is very good, so dark-colored clothes can also be printed on any of the light, but also a certain luster and dimension to clothing to see up more high-end, so it spread quickly, almost every piece of printed T-shirts will use it. However, it has a certain hardness, so not suitable for large-scale field pattern, large-scale patterns better use of water slurry to India, and then decorated some glue, this could solve the hard problems large mortar, but also highlight the pattern the sense of depth; Another method is to take time off large areas of the field pattern, made of bad results, but always wear a little of the hard, so best to just water, mortar combined to solve the problem better printing a large area .
3, foam printing process Known three-dimensional printing foam printing, foam printing process in the paste printing process developed on the basis of its principle is to add some mortar dye printing a certain proportion of the high expansion coefficient of chemical substances, After the printing position after drying with a foaming temperature of 200-300 degrees, achieve a similar "relief" of the three-dimensional effect, foam printing process visual substrates asked to do low-foaming effect is very eye-catching high school. Foam stamp printing process of the biggest advantages is the sense of a strong three-dimensional printing surface prominent swelling. Widely used in cotton, nylon and other materials.
Foam Printing paste Has been developed for the physical and chemical foaming foaming slurry pulp two series, the physical foaming slurry mainly containing microcapsule preparation, storage in the micro-capsules in a low boiling point organic Solvent When the temperature rises, the microcapsules preparation rapid gasification of organic solvents will be encapsulated bulging, swelling of the microcapsules squeeze each other, resulting in irregular overlapping distribution, therefore, uneven surface, it is also termed from velvet printing. There are two types of chemical foaming paste: a thermoplastic resin plus blowing agent is composed of such paste, the other is composed of polyurethane and solvent thickener paste. But the latter fabric printing paste in the solvent to be recovered to the printing plant has brought some difficulties, it is now generally use the former.
4, flocking printing process Flocking printing process is a three-dimensional printing process. The principle is that high-intensity light compound resin adhesive agent took place with a screen that contains the Transfer To the substrates surface, let the hair fiber by hundreds of thousands of volts of electrostatic field charged. Rapid vertical pile evenly to "hit" to the adhesive on the surface of the fabric, "shop" on a layer of fluff, and then by high temperature curing process. It is widely used in sofa fabric, packing boxes, shoes, fabric, decoration, toys, and other aspects of the protection of industrial electrical items. The fluff and covered the surface, the plants are not to be the shape, size constraints, flocking technology products produced three-dimensional feeling, bright color, soft feel, does not go down abrasion. Cotton, Silk and Jute, leather, nylon fabric, all kinds of PVC, denim, rubber, sponge, metal, foam, plastic, resin, cloth, etc. can be printed without defense.
Flocking adhesive chosen printing and dyeing industry plays an important role added. Commonly used adhesive binders are divided into cross-linking and self-crosslinking adhesive. Foreign-linked molecular adhesive containing its carboxyl (-C00H) or amide (-C-NH2), amino (-NH3) and other cross-linking agent with additional functional groups crosslink reaction groups. When the plastic film in conjunction with foreign agents reacted mesh film, and thus fixed to the fabric on the fluff.
