Digital pyrography method

Abstract

The invention discloses a digital pyrography method. The method comprises the following steps of pattern preparation, pattern layer printing, adhesion layer printing, hot melt adhesive layer printing,drying and transfer hot printing. Ink dissolved with hydrosol is directly printed on a heat transfer printing base material through a printing device to form a hot melt adhesive layer, then the hot melt adhesive layer is dried to obtain a needed pattern, and the tedious steps of hot melt powder scattering, excessive hot melt powder removing, hot melt curing to form the hot melt adhesive layer andthe like are not needed. The digital pyrography method is simple in step, simple in production process, easy to operate, low in production cost, high in yield, high in practicability and suitable formarket popularization and application, and a large number of devices and equipment for production do not need to be used and maintained.

Description

[technical field] [0001] The invention relates to a digital heat transfer method. [Background technique] [0002] Digital heat transfer is one of the processes of heat transfer printing. The existing digital heat transfer method generally includes the following steps: first print the pattern on the heat transfer film and other substrates, and then sprinkle hot melt powder on the heat transfer printing. On the film, then remove the excess powder, and then melt and solidify the hot-melt powder on the heat transfer film to form a hot-melt adhesive layer, so as to obtain a heat transfer film with a pattern, and finally transfer the pattern by pressing Print onto target materials such as cloth. Digital heat transfer has the advantages of bright colors, rich layers, and not easy to fade, so it has a broad market application scene. [0003] The existing digital heat transfer method needs to go through the steps of spreading hot melt powder, removing excess hot melt powder, hot me...

AI Technical Summary

Problems solved by technology

[0003] The existing digital heat transfer method needs to go through the steps of spreading hot melt powder, removing excess hot melt powder, hot melt solidification to form a hot melt adhesive layer, and needs supporting powder spreading devices, cleaning devices and hot melt curing devices. The process is cumbersome, the operation is complicated, and various production equipment needs regular maintenance, resulting in high production costs and low yields, which is not conducive to the widespread application of digital heat transfer
