Problems solved by technology

However, the bronzing process has one of the biggest shortcomings, that is, it is not possible to position the bronzing process on the part of the inkjet wet transfer printing type according to the needs of the inkjet wet transfer printing type; for example, when the inkjet wet transfer printing type is a flower , hot stamping gold on the flower core, or hot stamping on the outline of the flower, which will greatly improve the visual comfort of printed fabrics and increase the added value of printed fabrics

Abstract

The invention discloses a positioning gold stamping method of digital ink-jet heat transfer printing fabric. Firstly, a whole flower type is divided into a gold stamping printing part and a coloring printing part. A carrier is coated with a release layer and an ink absorbing layer firstly, through a digital ink-jet printing machine, thermal sublimation disperse dye ink and digital ink-jet hot meltadhesive ink are printed on the carrier in a sleeving manner, a thermal sublimation transfer carrier containing the coloring dye and hot melt adhesive is obtained and is attached to dacron fabric tobe printed, through pressing, printed fabric with hot melt adhesive positioning is obtained, finally, the printed fabric is attached to a gold stamping film, the fabric enters a gold stamping machineto be pressed, and the printed fabric obtained after positioning gold stamping is obtained. The digital ink-jet heat transfer printing positioning gold stamping process is achieved, the process is simple, the effect is good, the plate making procedure and the printing procedure of the traditional gold stamping process can be removed, the method is environment-friendly and energy-saving, the production period is greatly shortened, the production cost is greatly reduced, and through positioning gold stamping, the printed fabric graded and value can be improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, in particular to a positioning bronzing method for digital inkjet 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, elect...
