Background

At present, the most mature textile transfer printing process is a thermal transfer printing process, wherein transfer printing paper is attached to the surface of a textile, and then thermal effect treatment is carried out on the transfer printing paper through a high-temperature large steel roller heating process for covering felt positioning, so that the dye transferred to the textile is sublimated, and patterns and colors on the transfer printing paper are transferred to the textile, and anhydrous printing is realized. However, in the transfer process, corresponding problems easily occur, and the biggest problem is that the cloth is easy to cause certain wrinkles on the surface of the cloth due to the fact that the cloth is rolled up, if the wrinkles on the surface of the cloth are not smoothed, and when transfer paper is directly placed on the cloth for printing, certain blank areas occur on the easily produced printed cloth, and the printing effect is poor. The existing method can only rely on workers to smooth the cloth to a certain extent, so that the working efficiency is greatly reduced, and meanwhile, if the cloth is only smoothed, the position of transfer paper is not adjusted, the position deviation of the transfer paper on the cloth is easily caused, and the problem of poor transfer effect is caused.
