Method for transfer printing, positioning and stamping for fabric or leather

Abstract

The invention provides a method for transfer printing, positioning and stamping for fabric or leather, which comprises the following steps of: (1) selecting a base membrane, wherein the base membrane is selected from PET (polyethylene glycol terephthalate), BOPP (biaxially-oriented polypropylene), aluminum-plated stamping membrane or paper; (2) printing in a dyeing way; printing one color, firstly drying, and printing next color and carrying out the next drying, till that a preset pattern is formed by printing all color cells; (3) positioning and gluing, and printing the glue on the position to be gilded on the base membrane which is printed by ink, wherein the glue is selected from polyurethane or polyamide; and (4) gilding, gilding the position printed with the glue, and drying under low temperature and rolling simultaneously, so that the base membrane to be transfer printed, positioned and stamped attached with a dyeing pattern is prepared, wherein the drying temperature is from 50 DEG C to 60 DEG C; (5) hot-pressing; and (6) rolling in a separating way. The method has the beneficial effects of: being free from coating release agent, short in labor hour, and low in cost; advanced in gilding mode, quick in speed and good in effect, and capable of being secondly gilded.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a positioning bronzing method for fabric or leather transfer printing. Background technique [0002] At present, printing machines and cloth printing machines on the market have obvious excess productivity without new technology, and they are already in the phase-out stage. In order to make full use of these original machinery, create value again, avoid repeated investment and solve the original labor force, the transfer printing method has gradually replaced the traditional manual method (although there is machine assistance, manual ink and glue are still required) , such as the transfer printing method disclosed in the invention patents with patent application numbers 200710025329.3 and 201110121903.1, the existing transfer printing method generally includes selecting base film, coating release agent, printing ink, gluing, high temperature baking, heat transfer printing, separ...

Problems solved by technology

In order to make full use of these original machinery, create value again, avoid repeated investment and solve the original labor force, the transfer printing method has gradually replaced the traditional manual method (although there is machine assistance, manual ink and glue are still required) , such as the transfer printing method disclosed in the invention patents with patent application numbers 200710025329.3 and 201110121903.1, the existing transfer printing method generally includes selecting base film, coating release agent, printing ink, gluing, high temperature baking, heat transfer printing, separation Forming and other steps, the defects of the existing technology are: (1) The base film (PET, BOPP, aluminized film or paper) must be coated with a release agent (when printing inks with more than two groups of colors, it is necessary to apply a release agent to multiple groups of inks) Drying at the same time, if the release agent is not applied, the pattern will be stained, which will affect the printing effect), wasting materials and energy; (2) the color of the ink is relatively single, the drying time is long, the coloring effect is not good, and the pattern is easily stained; (3) ) Glue contains a lot of organic solvents, takes a long time to dry, and requires a long time of high-temperature baking (generally takes 12 to 24 hours, and the drying temperature is 60°C to 120°C), long production cycle, waste of energy, unfavorable for environmental protection, and slow production speed , can only print 20-30 meters per hour; (4) Glue can only be applied after the ink is dried, and cannot be printed and dried on the base film at the same time, otherwise the printing effect will be affected; (5) Glue application method Old, and the application part is not accurate (glue is not easy to dry); (6) After hot stamping treatment, the three-dimensional effect is not strong, and it is difficult to accurately locate for the second stamping, so it is impossible for customers to choose to stamp various transfer films and anti-counterfeiting again Laser film
