Heat sublimation transfer printing paper coating process

Abstract

The invention relates to a heat sublimation transfer printing paper coating process. The heat sublimation transfer printing paper coating process includes that one or several kinds of a porous inorganic filler, a cationic polymer, super-absorbent resin, low-viscosity starch and low-degree polymerization polyvinyl alcohol is taken as a base material of the front side of base paper of heat sublimation transfer printing coating paper, and a base coat is coated and primarily dried; one or several of high-viscosity starch, polyvinyl alcohol, carboxymethyl cellulose sodium starch and sodium carboxymethylcellulose is taken as a base material of the base coat of the front side of the heat sublimation transfer printing coating paper, and a coating side is coated and secondarily dried; one or several of high-polymer materials of polyvinyl alcohol, polyacrylamide, polyethylene oxide and the like is taken as a base material of the reverse side of the base paper of the heat sublimation transfer printing paper coating paper, and the back coat is coated and secondarily dried; the process is completed via stretching, press polishing, membrane compositing and rolling up. By the arrangement, general printing speed and drying requirements are met, high, medicum and low quality heat sublimation transfer printing ink is fitted, and transfer effect can be improved.

Description

technical field [0001] The invention relates to a thermal sublimation transfer printing paper coating process, in particular to a thermal sublimation transfer printing paper coating process suitable for high-speed printers. Background technique [0002] Sublimation transfer printing technology refers to the use of inkjet printers or laser printers to print sublimation transfer inks in the form of text or patterns on the working surface of sublimation transfer paper, and then use a heat transfer machine at a certain transfer temperature, heat press The process of transferring the pattern to the carrying object under time and heat pressure. The carrying object is usually a variety of cloth, and the material is mostly nylon, polyester, etc. The specific method is that the designer first designs different patterns or patterns according to the specific requirements of the customer, and then uses the automatic color matching system of the color printer to print the prepared sublim...

Problems solved by technology

However, with the rapid development of this technology, ink manufacturers continue to introduce water-based sublimation transfer inks in order to reduce environmental pollution and production costs. Water-based inks have high moisture content and strong penetration, which will reduce ink drying speed and damage heat transfer effect
