Pigment printing The printing method of coating printing is that the non-water-soluble substance particles with color or special effect are adhered to the fiber/fabric surface with a polymer adhesive to form the desired pattern. Paint printing characteristics 1.the process is simple and convenient, wide applicability to fibers; 2.Complete chromatography, bright color; 3.Clear outline and distinct hierarchy; 4.The disadvantage is that the feel is hard, the fastness is poor. Composition of pigment printing paste 1.Pigments (or color-changing pigments, pearlescent powder, functional powder, etc.); 2.Adhesive; 3.Thickener; 5.Water. The adhesive is known as a coarse and fine printing and dyeing aid. Rough refers to different from ordinary textile additives, the price is high, the amount of addition is small, the price of the adhesive is low, the amount is large, fine refers to the nature of the adhesive determines the key properties of the paint printing feel, contour, fastness and so on, is a high technical content of the auxiliary. Non-reactive adhesive 1.polyacrylate copolymer 2.butadiene copolymer 3.vinyl acetate copolymer Reactive adhesive Amino type, hydroxyl type, self-crosslinking type Raw materials used in adhesive: Monomer Emulgator Initiator Typical problems encountered by factories Environmental issues of emulsifiers: The NP and OP series emulsifiers widely used in the early years are prohibited for environmental reasons, and the current adhesive manufacturers generally replace them with AEO series and isomeric 13 alcohol ether series, but their emulsifying power is difficult to match the NP and OP series, and the cost performance is not high. Adhesive feel problem: Due to its product characteristics, paint printing feels worse than dye printing, domestic manufacturers generally increase the softness by adjusting the proportion of soft and hard monomers and adding silicone feel regulators, but it is difficult to perfectly balance the softness and fastness.

Let's take a look at the characteristics of water-based acrylic emulsion! 1.Excellent adhesion The polymer structure of the aqueous acrylic emulsion contributes to the flow and wettability of the molecular chains on the surface of the substrate, making the coating and the substrate molecules in close contact to achieve high adhesion. 2.The high bearing capacity of the filler can significantly reduce the cost The water-based acrylic emulsion has excellent filling properties, and the total solid content of the coating formulation can reach 60%. Among them, the ratio of resin to filler can reach 1:2, which significantly reduces the formulation and use cost of water-based wood paint. 3.Zero VOC safety and environmental protection The water-based acrylic emulsion itself does not contain VOCs and can form a film at room temperature without film forming additives. Coatings formulated in this way can have a VOC content of zero. 4. Excellent water resistance Aqueous acrylic emulsions do not contain the surfactants used in ordinary acrylic emulsions, and have specially designed hydrophobic groups. Therefore, the water-based acrylic emulsion has excellent moisture resistance, which can prevent the penetration of water molecules on the substrate after the paint film is dried, and achieve the effect of waterproof and moisture-proof. 5.Excellent weather resistance The molecular structure of water-based acrylic emulsion adopts UV-stabilized monomer structure, and the emulsion is specially designed to make TIO2 fully and evenly dispersed in the emulsion, reduce the influence of UV on the emulsion, and effectively protect the substrate. 6.Excellent pigment dispersion Water-based acrylic emulsion and various water-based color paste compatibility is good, so that the function of fillers and pigments can be maximized, and the paint color is bright.

1 Fluorescent ink: Fluorescent ink is made of fluorescent material dissolved in the corresponding resin. The particles of fluorescent pigments are generally thicker, the types of bonding materials are more, different bonding materials will produce different fluorescence, in the use of fluorescent ink should ensure that it has sufficient concentration, the ink layer on the printing product is thicker, so as to ensure satisfactory fluorescence effect. Fluorescent ink after screen printing printing bright color, decoration effect is very good, under the action of visible light and ultraviolet light, can emit sparkling fluorescence. 2 Photochromic ink: UV ink photoinitiator is a compound that is easily excited by light, excited into free radicals after absorbing light, and the energy is transferred to photosensitive molecules or photocrosslinking agents, so that UV ink photocuring reaction occurs. UV ink has become a more mature ink technology, and its pollutant emissions are almost zero. In addition to solvent free, UV ink also has such advantages as not easy to paste, clear dot, bright ink color, excellent chemical resistance, consumption and so on. 3 Light storage and phosphorescent ink: Light storage pigment is the use of inorganic fluorescent material with phosphorescent effect of some zinc sulfide. Copper fluorescence, calcium sulfide. Prepared from bismuth fluorescence, etc. Inorganic fluorescent matter is by crystal light, if the pressure will make the crystal rupture, resulting in reduced luminosity, so the general use of screen printing is more suitable, ink carrier and fluorescent matter in use mixed. The characteristic of phosphorescent ink is to absorb light and then emit light at a certain wavelength within a certain time. The pigment of this ink is zinc sulfide containing a small amount of impurity (such as zinc cadmium sulfide), it is afraid of acid, afraid of alkali, so it requires the use of neutral resins such as cyclohexanone resin, fiber ester and ether. In addition, heavy metals, desiccant and drying oil should not be added to the ink to avoid damaging the pigment substance. The binding material used should be transparent and be able to penetrate ultraviolet light. This ink is mainly used for printing advertising and signs, but if phosphorescent ink and fluorescent ink are mixed for anti-counterfeiting packaging printing, you can receive good packaging decoration and anti-counterfeiting effect. 4 Special printing ink: Printing ink is mainly composed of colors, fillers, linking materials, etc., of which the composition of the color is an important part of determining the color and brightness of the printing, many manufacturers and ink factories customize the special ink for each product printing, and the formula is kept secret by the ink factory. 5 Compound ink: After two or more kinds of anti-counterfeiting inks are mixed according to a certain proportion, composite inks with new properties can be developed, and it will be diffi...
