Self-adhesive quick-drying thermal sublimation transfer printing digital cloth

Abstract

The invention relates to the technical field of thermal sublimation transfer printing, and discloses a piece of self-adhesive quick-drying thermal sublimation transfer printing digital cloth. The digital cloth sequentially comprises a piece of digital substrate cloth, an adhesive water-pervious layer, a water-absorbing layer, an ink-absorbing layer and a mesh-shaped surface layer from bottom to top, wherein the water-absorbing layer comprises mesopores and is an acrylic acid-2-acrylamide-2-sodium methacrylate copolymer; the mesh-shaped surface layer comprises a polyvinyl alcohol-vinyl acetate copolymer and sodium carboxymethyl cellulose; the digital substrate cloth has better strength than a paper substrate material, can be repeatedly used, the production cost is saved, and meanwhile, the production efficiency is improved; holes are formed in the hydrophilic end of the water-absorbing layer, so that moisture in ink is adsorbed into the holes, and the ink transferred to a dielectric material is quickly dried. The structure of the mesh-shaped surface layer facilitates quick absorbing of the ink in the printing process; in the transfer printing process, maximum adhesion of the mesh-shaped surface layer and the dielectric material can be realized, and the technical problem of double pattern imaging caused by the fact that the printing ink is prone to moving during absorption and transfer printing is solved.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to self-adhesive fast-drying thermal sublimation transfer digital cloth. Background technique [0002] Printing and dyeing is a general term for dyeing, printing, finishing, washing and other processing methods. my country's printing and dyeing has an important impact on the global clothing industry, but it also produces huge amounts of wastewater and environmental problems. With the advent of green chemistry and personalized digital age, thermal transfer printing technology is developing rapidly. Thermal transfer printing is a technical form that uses thermal transfer equipment to heat the patterns and images on the thermal transfer paper to 180°C-230°C, and transfer and print them on different material media. [0003] However, in the prior art, the reutilization rate of the thermal transfer digital template is relatively low, which not only increases...

Problems solved by technology

[0003] However, in the prior art, the reuse rate of the thermal transfer digital template is relatively low, which not only increases the production cost, but also wastes time when replacing the thermal transfer digital template

In addition, there are still the following disadvantages in the prior art: it is easy to shift during transfer, which makes the transferred pattern blurred, the yield is not high, and the ink drying speed after transfer is relatively slow, which affects the stacking of printed matter in industrial production. release, and thus cannot meet the needs of industrialized mass production
