 Water paste printing: here are talking about water slurry is a type of strong aqueous slurry suitable printed on light colored fabrics, be wider printing category. But it also exists an advantage: Because of its relative does not interfere with pre-existing fabric texture, it is more suitable for use in large-area printing pattern. Features: feel soft, shiny bright colors, but the presence of an aqueous slurry of the major drawbacks, namely an aqueous slurry of color than some light color fabric printing factory, fabric color to be darker, not on the water slurry basic coverage. To improve color fastness of printing products by adding a certain amount of N- methylol acrylamide is necessary, it can be crosslinked by acrylate monomers and, and also with hydroxyl crosslinked cotton fabric, effectively strengthening the intermolecular binding force, thereby increasing the film abrasion resistance and reduce viscosity. In the present system prints, due to polymerization of organosiloxane involved, so that the mechanical film strength and adhesion decrease, was added hydroxylamine can be effectively restored, its effect on the polymer emulsion and applications. Hydroxylamine gel fastness to wet grinding dry grinding amount fastness feel free soft, smooth three free soft, level 4 three small amount of soft and smooth, smooth grade 4-5 level 4 cohesion above results show that with the increase of the amount of hydroxylamine of printing products fastness has significantly improved, but too much will cause difficulties in emulsion polymerization, condensation phenomena arise. This is due to cross-linking is too large, the emulsion thickens, the heat blocked reactive monomer, resulting in decreased stability. This product hydroxylamine amount of 2% to 4% in emulsion polymerization, adding acrylic monomer activity, the morphology of latex particle nucleation has great influence, and the addition of 2% to 4% of acrylic acid can significantly improve the adhesive strength of the polymer emulsion paint color paddle improve wettability and compatibility. Selection of type and amount of emulsifier emulsifier directly affect the stability of the emulsion particle size and the system, resulting in electrostatic repulsion between each other, so that the binding force between the emulsifier and the latex particles are fragile, this combination can easily be outside (such as pigments, dielectrics, etc.) are damaged, resulting in destabilization of the emulsion. Factors textile colorants applied when printing with special coatings, printing paste having first of all have different characteristics, so look at its origin. Knitted pigment printing, in its elastic extension, the printed parts will appear white (also called white ink) printing materials, gold and silver powder coating slurry printing is also subject to the impact of low pH, the factors affecting the applied paste (1) Colorants motion wedge elements contact time T (s) represents a cylinder bore of a network from the slurry into the memory wedge starts printing, leaving the embossing points (blade or rotary magnet with a contact point) up to, through which time, by deposit pulp wedge width B (mm) and printing speed V (m / s) decision: T = B / VB can be pressed into the wedge from the Indian pulp and geometry to calculate the amount. Generally considered high printing speed by squeezing the paste will be more powerful, leaving the pulp to increase. But in fact found that high printing speed so they will be applied to reduce the amount, which will reduce the printing speed makes for plasma volume increases. The reason is because the printing speed is high so that time is reduced, the contact time mesh and paste reduce the amount of paste oozing reduced. Practice has proved that this factor is more dominant than the other factors. Paste viscosity greater the impact velocity change generated greater. In recent years, our country has been reported to be modified by blending method, but unstable emulsions, film strength is greatly reduced, and the method of modified copolymer, the current research and application is also very small. By silicone-modified acrylic resin leather finishing agents, the use of the same with slurry from the bottom to the middle of finishing, can achieve very good surface properties. The main quality indicators emulsion appearance, fluorescent milky white liquid thermal stability, chemical stability and no precipitation is dedicated general-grade leather finishing agents.
