In the colorful Textile In Printing Home Fabrics is no doubt the most important position. According to Ciba estimated global production of printed fabrics every day more than 4,000 meters, of which half of the production in Asia, production in North America only 1l%, 70% of printed fabrics as cotton or polyester-cotton fabric. Printed Fabrics Paint 65%, 15% of reactive dyes, disperse dyes, 10%, acid and other dyes account for 10%. Printed fabric jacket for women Consumption 40% Bedclothes 25% Shirt , Furniture Cloth And other products account for 35%. Most of these printing currently using traditional screen printing process, Package Including flat screen and rotary screen printing. Screen printing Colorants Generally by the dye (or Pigment ), Additives The composition of the original paste. The role of the original printing paste is to paste a certain viscosity and flow, it is by the modulation of hydrophilic polymer material paste is made. Paste in the screen printing pa ste formulation play a key role, which controls the printing paste rheology and printing color penetration and migration. In addition to dye performance, the paste is to determine the printing quality of the most important factor. Currently the largest amount of natural paste, including sodium alginate (generally used for reactive and disperse dyes printing), melon children bean gum or other plant seeds, plastic (commonly used for printing disperse dyes), and Starch (For vat dyes printing). Natural paste the advantage of easy to clean after printing solid color and form solid protective film to prevent printing color stick ride. The drawback is a longer time required to complete hydration (8? 24h), may be related to dye reactions to color in lower levels. With Acrylic acid ( PA A) for the generation of Table There are synthetic paste fake plastic rheology of the shear thinning properties, viscosity changes under stress, whereas in stress relief are immediately returned to th e original viscosity. Therefore, synthetic paste only l% ~ 3% concentration is effective, while 10% of natural paste concentration required to achieve the required paste viscosity, and the synthesis of paste hydration speed, printing a clear pattern, the ideal permeability, to the large amount of color, better color evenness. However, the traditional PAA paste on the electrolyte sensitivity, high concentrations of lead paint color paste viscosity decreased significantly, and sometimes fixing problems after the desizing. New development of printing paste, including a new generation of PAA paste, synthetic and natural blended paste, applied against the Emulsion Technology to produce particles in a more uniform paste. The new paste can improve the color of printed fabrics, soft degrees and permeability. In textile printing, the paste can control the flow of paste to prevent the proliferation of pigment. Printing quality such as clarity, brightness and color of dye penetration a nd infiltration, etc. depending on paste properties. Beyond the pigment printing, the main use of natural or modified natural paste paste, while coal and oil-water emulsion pigment printing normally. However, there are some limitations of the natural thickener, such as raw material is not rich, poor stability performance, poor liquidity, high cost (eg, alginate). Also, according to the dye and printing machine types, to select different print natural paste for trial and adjustment, rather than a blend of synthetic paste or paste can be used various dyes manufacturers introduce products supporting paste. Synthetic paste the color yield as high solid content is low, the storage time is long, easy to handle, there are pseudoplastic, the global trend is replaced with a synthetic paste of natural paste, particularly pigment printing synthetic paste materials can solve the problem of pollution of kerosene emulsion. The application shows that the reactive dye printing synthetic pas te instead of using alginate to reduce costs; used in the synthesis of disperse dyes printing paste, due to low solid content helps fabric dye transfer from the colorant, may therefore be increased color volume. Raw materials to ethylene synthesis paste maleic anhydride, acrylamide, acrylic and acrylic-based monomer, monomer composition and performance properties, especially on the paste viscosity of printing paste and dry film of a decisive influence. Acrylic is used to achieve the required paste viscosity, can join the base and acrylic ester Polymer Have some flexibility. Therefore, according to different uses, select monomer and its composition. Synthesis paste needs to select the appropriate crosslinking agent, and add the appropriate Surfactant From an environmental point of view, although the degradation of natural paste easier, but the use of natural paste is much greater than synthetic paste, it will have a certain amount of pollution. Synthesis of the main raw mater ial paste is clean acrylic-based chemicals, and the degree of polymerization of synthetic paste is not high, with much smaller than the natural paste, so the application in the printing synthetic paste and will not increase the amount of pollution . Synthetic paste shear flow with the inherent nature of hair color for printing can be more brilliant. More fine lines, clear, color blocks more evenly. But the general synthetic preparation of active dyestuff paste can not be used because of its extremely sensitive dye ions in the washing after printing, the fabric will be formed in a white precipitate. Thus affecting the quality of printed fabrics feel and appearance of the United States B. F. Goodrich, researchers made use of new synthetic polypropylene acid paste, its ion sensitivity is low, and can be completely cleaned. In addition, it can reduce by half the amount of urea printing, help reduce wastewater BOD, fast mixing, without affecting the dye 1 Fiber Bond formation. In experiments using three kinds of new paste: Carbopol249I (sodium and liquid), Carbopol2491WC (dust powder) and Carbopol2491WCS (and clean themselves in the powder), and compared with sodium alginate, with 7 different activity Dye printing. The results show that, Carbopol paste get more brilliant color, lines more clearly, feel more flexible printing quality. BASF's new LutexalG PE CO thickener for pigment printing can improve the contour definition and printing reliability, while lowering costs, reducing environmental pollution. Trial results show that plant. This printing paste printing not only clear line, and running good performance, more brilliant colors brighter. In the natural fiber or synthetic fiber on the printing are good color fastness, it can reduce printing penetration, thus saving paste. The paste on the electrolyte, high stability, viscosity, volatility, printing reproducibility increased to increase the rate of the same color batch. The paste for the powder , can provide particulate products that smoke less than the liquid products, therefore, granular powder thickener is the future direction of this new type of thickener used Printed Products Meet the European eco-standards such as Oko-Tex Standard 100 and so on. Traditional printing technology users face new requirements for high quality low-cost challenges, prompting screen printing technology continues to improve. In recent years, digital Ink jet Printing has made a major breakthrough. But Expert Predicted to replace the traditional printing process also requires considerable time with the direct dye printing dyeing
