Production process of grained pyrograph

Abstract

The invention discloses a production process of a grained pyrograph. The process includes the steps of: making a grained carrier; performing drying, and letting silicone rubber generate grains on thesurface of a PET rubber sheet; then applying screen printing waterborne polyurethane ink to the surface layer of the dried carrier, and using a dye blocking agent for screen printing at the back of the pattern to serve as a backing; then conducting screen printing of a transparent waterborne high elastic polyurethane resin layer by a screen printing plate larger by 0.18mm; and conducting drying bya 140DEG C tunnel furnace for about 2min to melt polyester powder and form a bonding layer on the surface. The process provided by the invention can reduce the production cost and improve productionefficiency, also can achieve personalized customization of any grain effect at will without increasing the cost, has no need of making any mold, after transfer printing, the color is bright, the product only needs 1-2min of drying every time in the production process, and the old production process generally needs hours of drying totally and consumes a lot of energy.

Description

technical field

[0001] The invention relates to heat transfer, in particular to a production process of pattern heat transfer. Background technique

[0002] Thermal transfer heat transfer is widely used in many fields such as clothing, bags, shoes, etc. At present, the market is not satisfied with the flat heat transfer effect, and there is an increasing demand for special three-dimensional heat transfer heat transfer with texture. This kind of heat transfer gives people a refreshing feeling both visually and in hand, and greatly improves the grade of the decorated products.

[0003] At present, some of the production processes of textured heat transfer on the market use molds to emboss specific patterns before printing patterns or after printing patterns, and then print the adhesive layer, so as to achieve embossing effects during transfer printing; some The method is to directly screen-print patterns and adhesive layers on the thermal transfer release film that has been p...
