To Pigment Or dyes Print In the paper, Rubber Or other vector, then Pad To be printed on the said goods Transfer printing However, in terms of transfer of India means the narrow needle Textile Printing technology for carriers. Transfer printing is mainly used in polyester Fiber Products on, with the transfer printing of the improvements in Nylon , Acrylonitrile , Cotton, hemp, and wool is also widely applied. Transfer printing sub-wet, dry, steam, vacuum, thermal methods, and other means. Transfer printing method can accurately reproduce designs, easy to mechanized production, and the process is simple, especially after the treatment process than the traditional printing Printing and dyeing Simple printing and dyeing feel the same, so much to gradually replace the old method of printing potential. However, the majority of printing and dyeing plant in China is still mostly traditional dyeing method, only a few units were produced by transfer printing. Currently using broader external hot melt polyester resin addition there Polyamide , Vinyl acetate Copolymers and polyurethane, etc.. Polyester hot melt adhesive is the main component of polyester resin, polyester resin is a multi-acid. Were esterified with polyols derived. Poly-acylamino-melt adhesive resin adhesive ability, toughness, resistance to low temperature and nylon fabrics preferred affinity for the preparation of nylon transfer printing paper. Ethylene - vinyl acetate copolymer low melting point, strong adhesive, adding print Ink After the application of transfer printing paper production. Polyurethane hot melt adhesive is mainly used for skin Leather Hydrogen bonding and poly ethylene plastic. Transfer printing fabric printing as to be different, the best use for the hot melt ink. I. Characteristics of transfer printing method (1) transfer prints with vivid patterns, pattern detail, level of clear, strong sense of three-dimensional features. Transfer printing can be printed natural scenery and strong artistic design. (2) transfer Printing Equipment Simple structure, small footprint, low investment, economic efficiency is high. As the device is tension-free processing, suitable for all kinds of thickness of the printing. In addition, after the transfer printing without post-processing can be Package Factory. (3) transfer printing does not exist the problem of environmental pollution. As the dry process, without washing, steaming, drying process, so no emissions and waste discharge. (4) transfer printing with high efficiency, saving labor and the advantages of simple operation. Second, transfer printing mechanism Transfer printing are used for Polyester Fabric. It is through high temperature (200 so) to heat l dye Huawei Gas condensation polyester Table Surface, and then to the fiber molecules in the amorphous zone penetration, by fixing the fiber after cooling the internal printing methods. Third, dye transfer printing on demand Disperse dye transfer printing applications, the sublimation temperature should be lower than the melting point of fiber molecules and does not damage the fabric strength of the principle of PET is more suitable processing temperature for the 180 - 210 . In this temperature range, the dye sublimation occurring varieties of its molecular weight of 230 - 270 among. Molecular weight in this area generally have three kinds of disperse dyes. Fast dyeing disperse dyes: the temperature at about 180 can be sublimated and hair color temperature is further increased, since the color change, and penetration of the edge occurs. Good of disperse dyes: temperature 180 - 210 range of hair color can be sublimated. Hair color and smooth curves. Dyeing temperature had little effect when it is more appropriate for transfer printing of disperse dyes. Late dyeing disperse dyes: the 180 - 210 not very good circumstances dye sublimation, and hair color. Such as increasing temperature, can get a good hair color. When this type of dye strong dependence on temperature. The above, apply to transfer printing of dyes should meet the following conditions: (1) dye transfer printing to be fully under 210 sublimation, fixation on the fiber, and can get a good wash fastness and ironing fastness. (2) after heat transfer printing dye sublimation into a gas can full dye molecules, concentrated in the fabric surface, and can spread to the internal fiber. (3) transfer printing on transfer paper using dye affinity to small, the affinity of the larger fabric. (4) transfer printing dye should have bright, bright color. Fourth, transfer paper, color printing ink We are high quality suppliers, our products such as rear projection bulbs Manufacturer , replace projector bulb Manufacturer for oversee buyer.
