Problems solved by technology

However, the hot stamping process has one of the biggest shortcomings, that is, the hot stamping process cannot be positioned on the part of the flower type according to the needs of the flower type; for example, when the printed pattern is a flower, gold is hot stamped on the flower core, or Gold is hot stamped on the outline of the printed fabric, which will greatly enhance the visual comfort of the printed fabric and increase the added value of the printed fabric

Abstract

The invention discloses a positioning bronzing method for a wet transfer printing fabric. The method includes, firstly, coating the printing surface of a printing carrier with a release layer and an ink absorption layer; secondly, coating a bronzing printing part with a hot melt adhesive slurry; then, sleeving and printing patterns on the coloring printing part to obtain a wet transfer carrier containing a hot melt adhesive; bonding and hot pressing the wet transfer carrier with a wet fabric to be printed to obtain a dye printing fabric with the hot melt adhesive; and finally, bonding and hotpressing the dye printing fabric with a foil film to obtain the positioning bronzing printing fabric. According to the method, positioning bronzing of wet transfer printing is realized, visual comfortof the printed fabric is improved, and the selling price of the printed fabric is improved; especially in the current increasingly fierce market competition, product differentiation is realized, andthe market competitiveness of the product is improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, in particular to a positioning bronzing method for wet transfer printing fabrics. Background technique [0002] Textile printing is divided into color printing and special printing. Among them, colored printing refers to dye printing or pigment printing, which is to apply dyes or pigments capable of dyeing textile fabrics to local parts of the surface of textile fabrics by physical or chemical methods, and then through physical or chemical reactions. , so that the dye or pigment is deposited, and has a certain combination fastness with the textile fabric fiber, and forms a partial dyeing process for the textile. It often uses red, yellow, blue and black as the basic colors, and mixes various colors. [0003] Special printing refers to the application of some special materials to the surface of the fabric through screen printing, roller coating, hand-painting, transfer, electrostatic at...
