Technical Field

The invention relates to the technical field of printing, in particular to thermal transfer printing equipment for reducing defects of printed cloth and a processing technology thereof.

Background

The most mature textile transfer printing process at present is a thermal transfer printing process, which is to attach transfer printing paper on the surface of a textile, and then make the transfer printing paper perform thermal effect treatment through a high-temperature large steel roller heating process for positioning a wrapping felt, so that the transferred pigment sublimates, and the pattern and the color on the transfer printing paper are transferred to the textile, thereby realizing anhydrous printing. However, the corresponding problem is easy to occur in the transfer printing process, wherein the biggest problem is that the cloth is easy to cause certain folds on the surface of the cloth in the rolling process, and if the folds on the surface of the cloth are not smoothed, and the transfer printing paper is directly placed on the transfer printing paper for printing, the produced printed cloth is easy to generate certain blank areas, so that the printing effect is poor. At present, the existing method only depends on workers to smooth cloth to a certain extent, which also results in great reduction of working efficiency, and meanwhile, if the cloth is only smoothed, the position of transfer paper is not adjusted, the deviation of the position of the transfer paper on the cloth is easily caused, and the problem of poor transfer effect is caused.
