Transferring printing carrier

Abstract

The transferring print carrier has one color pattern layer of water thinned printing ink comprising color material 10-20 wt%, adhesive 50-85 wt% and additive 2-25 wt%. The present invention can transfer color pattern to natural fiber material in one step, and the transferring process has simple operation, low cost, no influence on the property, hand feeling, softness and ventilation of the fiber material and no environmental pollution, and the transferred pattern is clear and bright.

Description

technical field [0001] The invention relates to the field of transfer printing, in particular to an environment-friendly transfer printing film used for natural fiber materials and textiles thereof. Background technique [0002] Transfer printing technology is widely used in textile, clothing, decoration and other industries. There is a more widely used transfer printing paper, which uses disperse sublimation dyes. Under high temperature, the dye surface of the transfer printing paper sticks to the adhesive layer to be fixed, and then the protective agent layer is applied after the adhesive layer is cured. The color of the product obtained by this technology is only on the surface of the fiber. Therefore, in the atmospheric environment, it is easy to fade and fade after a long time. In addition, the product after transfer printing has a bad hand feeling, is not breathable, not soft, high cost, and not environmentally friendly. , this transfer printing paper is generally onl...

Problems solved by technology

The color of the product obtained by this technology is only on the surface of the fiber. Therefore, in the atmospheric environment, it is easy to fade and fade after a long time. In addition, the product after transfer printing has a bad hand feeling, is not breathable, not soft, high cost, and not environmentally friendly. , this transfer printing paper is generally only used on chemical fibers and leather, and can not be used on natural fiber fabrics. For this reason, people have carried out a large amount of research to overcome the above-mentioned shortcoming, such as CN85102070A "transfer printing paper and transfer printing of textile materials" There is a new concept of transfer printing paper, that is, a coating is made on a flat substrate. This coating includes an impregnating agent that is cured at 60°C and liquefied at least at 230°C, a binder, and a water-insoluble dye which does not sublime significantly under sublimation transfer printing conditions and which is soluble in the above impregnating agent in liquid form, after which a printed pattern or design is printed on this coating

This technical solution is said to not require special pretreatment of cellulose-containing textiles, thus solving the transfer printing effect of traditional transfer printing paper on cotton, linen, regenerated cellulose, and their synthetic fibers, especially polyester blended fabrics. The problem is not good, but this technical scheme is complicated to make, which leads to high cost. Due to the solid impregnating agent and adhesive coating at room temperature, which affects the properties of natural fibers, the hand feel and air permeability are poor, and the production process must The solid impregnating agent must be heated to a temperature above 230°C to turn it into a liquid to dissolve the dye and mix it into the adhesive, which will definitely cause environmental pollution

Because the uppermost layer of the transfer printing paper is the pattern layer, the middle layer is the coating containing the dye, and the lower layer is the base layer, and after the transfer printing is applied to cellulose fabrics such as cotton cloth, the pattern layer is on the bottom, and the coating is covered on it. Knowing the clarity of the pattern, the vividness of the color will be seriously affected by the coating, and the effect will be poor
