Coating classification: water-based color paste printing adhesive for textile coating

Core tip: when the water-based color paste is used for pigment printing, the adhesive must be used The function of the adhesive is to bond the water-based color paste coating and the textile fiber In order to achieve the printing effect of the high-quality water-based color paste coating for textile, the adhesive is needed It forms a soft resin layer in the use process, which is colorless, non sticky and firmly adhered to Textile fiber, good insolation performance, dry cleaning resistance and will not produce too rough feel In the drying process after printing, the binder carries the water-based pigment to form a thin film Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: When the water-based color paste is used for pigment printing of textiles, an adhesive must be used The function of the adhesive is to bond the water-based color paste coating and the textile fiber In order to achieve the printing effect of the high-quality water-based color paste coating of textiles, an adhesive is needed, which forms a soft resin thin layer during the use, colorless, non sticky, and firmly attached to the textile fiber , good insolation performance, dry cleaning resistance and will not produce too rough feel In the drying process after printing, the binder carries the water-based color paste to form a film In the first process of drying, the dispersant and emulsifier in the printing paste are evaporated to form a gel layer, and the gel layer is film-forming and loosely adhered to the textile fiber In the second fixation process, the binder cross-linked on the textile fiber under the condition of acid (pH < 4) If synthetic thickeners are used, there is no need to add additional acidic media to the printing pastes of textile water-based pastes, because during fixation, the neutral thickeners will return to acidic conditions At present, there are three types of binders used in the printing of textile water-based color paste: 1 Acrylic adhesive 2 Butadiene adhesive 3 Acrylic adhesive acrylic adhesive acrylic adhesive acrylic adhesive is mainly composed of acrylate and ethylene copolymer These binders can ensure that the water-based pigment printing of textile fabrics has better color fastness performance and suitable hand feel on textile fibers, but there are some limitations in the color fastness of dry cleaning Most of the current products on the market belong to this category and have been used for more than 30 years In the mind of printing workers, acrylic adhesive is better for hand feeling and fastness of printed fabrics Butadiene binder this kind of binder can usually give textile water-based pigment printing a soft hand on textile fibers, but in some cases, printed fabrics will become sticky Although the overall color fastness performance is very good, however, the durability is limited After a period of time, the color turns yellow, affecting the light color Due to this negative characteristic of butadiene adhesive, it is rarely used in practice This kind of adhesive can provide the soft hand feeling of textile water-based color paste coating printing on textile fiber, and the product combined with acrylonitrile has very good fastness in dry and wet rubbing, water washing, dry cleaning and other aspects Nitrile soft bonding can be used in the printing of water-based color paste coating not only on pure cotton fabric fibers, but also on silk fibers, synthetic fibers and blended fabrics, such as pure nylon fibers, pure polyester fibers and their blended fabrics with cotton or viscose It is difficult to use acrylic adhesives to print these fabric fibers Nitrile binder also has some other advantages After printing with this binder, the fabric has suitable water absorption property, which is very important for chemical finishing such as waterproof, antifouling and flame retardant When the amount of nitrile binder is increased for the sake of better color fastness, it will not affect the hand feel of the fabric like acrylic binder Nitrile adhesive will not affect the down effect of the fabric like acrylic adhesive (such as corduroy, peach skin and towel fabric, etc.) and keep the natural effect of the fabric itself Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
