Abstract

The invention relates to the technical field of sublimation transfer printing, discloses self-adhesive quick-drying sublimation transfer printing digital paper. The paper includes, from the bottom to the top, a base material sheet (1), a hydrophobic layer (2), a water-absorbing layer (3), an ink-absorbing layer (4) and a net-shaped surface layer (5), wherein the water-absorbing layer (3) includes interspace holes and is made of acrylic acid-2-acrylamide-2-sodium methacrylate copolymer; the net-shaped surface layer (5) is prepared from, in parts by weight, 25-45% of polyvinyl alcohol-vinyl acetate copolymer and 55-75% of sodium carboxymethyl cellulose; holes are formed in the hydrophilic end of the water-absorbing layer, so that the water contained in the ink can be adsorbed into the holes, and the beneficial effect that the ink can dry quickly after being transferred to a medium material is achieved. According to the invention, the net-shaped surface layer (5) structure facilitates quick absorption of the ink during the printing process; during the transferring process, the net-shaped surface layer can realize maximized adhesion to the medium material; the technical problems that the pattern is blurred or overlapped with another because of easy displacement during the printing ink absorption and transferring processes are 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 paper. 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, there are the following disadvantages in the prior art: it is easy to shift during transfer, which makes the transferred patt...
