Embodiment 1

[0032] Preparation of solvent dye ink: first take 40 parts of butyl acetate (parts by weight, the same below), 30 parts of butanone, and 10 parts of cyclohexanone, put them in a stirring tank, and then take 3 parts of oil-soluble black with dye index number 27# , at room temperature, slowly add 27# black powder and stir at a low speed (speed 100rpm), until the dye is completely dissolved. Then add 7 parts of polyvinyl acetal resin, stir at 1300 rpm for 30 minutes, add solvent butanone to adjust the viscosity to 1400 centipoise.

[0033] Put the above ink in the ink tank of the gravure printing machine, install the printing plate, adjust the scraper, print on the PET film, dry, and roll up to form the transfer film.

[0034] A mixed solvent of ethanol and methyl ethyl ketone (v: v = 1: 1) is prepared, added to a roller printing machine, and the microfiber leather is passed through the roller printing machine, so that the microfiber leather is evenly wetted for use.

Embodiment 2

[0042] Preparation of solvent dye ink: first take 33 parts of ethanol (parts by weight, the same below), 25 parts of ethyl acetate, and 10 parts of ethyl cellosolve, put them in a stirring tank, and then take dye index number 8# oil soluble red 15 At room temperature, slowly add 8# red powder and stir at a low speed (200rpm) until the dye is completely dissolved. Then add 7 parts of polyvinyl acetal resin, stir at 1300 rpm for 30 minutes, and add ethanol to adjust the viscosity to 1350 centipoise.

[0043] Put the above ink in the ink tank of the gravure printing machine, install the printing plate, adjust the scraper, print on the BOPP film, dry, and roll up to form the transfer film.

[0044] Prepare a mixed solvent of butyl acetate and isopropanol (v: v = 3: 1), add it to the spraying machine, and pass the microfiber leather through the spraying machine to make the leather uniformly wet and ready for use.

[0045] The printed transfer film is attached to the wetted leather, ...

Embodiment 3

[0051] Preparation of solvent dye ink: first take 50 parts of ethyl acetate (parts by weight, the same below), 20 parts of butanone, and 10 parts of cyclohexanone, put them in a stirring tank, and then take 3 parts of dye index number 62# oil-soluble orange , at room temperature, slowly add 62# oil-soluble orange powder and stir at a low speed (speed 100rpm), until the dye is completely dissolved. Then add 7 parts of ethyl cellulose resin, stir at 1300rpm for 30min, add solvent butanone to adjust the viscosity to 1400 centipoise.

[0052] Put the above ink in the ink tank of the gravure printing machine, install the printing plate, adjust the scraper, print on the PET film, dry, and roll up to form the transfer film.

[0053] A mixed solvent of ethanol and ethyl acetate (v:v=1:3) was prepared, added to a roller printing machine, and the cork board was passed through the roller printing machine, so that the cork board was evenly wetted for use.

Abstract

The invention discloses a new micro fiber leather or leather or cork wet transfer printing method comprising the following steps of: preparing a wet transfer printing film by carrying out gravure of a film by using solvent dye ink; moistening an organic solvent for the micro fiber leather or the leather or the cork by spraying or rolling marks; bonding the moistened micro fiber leather or the leather or the cork and the transfer printing film; transferring solvent dye on the transfer printing film on the micro fiber leather or the leather or the cork by pressurizing and heating; and drying or airing the transfer-printed micro fiber leather or leather. The invention also discloses a wet transfer printing film used in the method. The invention creatively proposes to use the solvent dye as the wet transfer printing colorant and use a solvent which can smoothly dissolve the solvent dye as a wetting agent of printing stocks, breaks through the limitation that water is necessary for the traditional wet transfer printing, and enlarges the application range of the wet transfer printing.

Description

technical field [0001] The invention belongs to the printing and printing and dyeing industry, and in particular relates to a new wet transfer printing method of microfiber leather, genuine leather or cork and a wet transfer printing film thereof. Background technique [0002] The full name of microfiber leather is "microfiber reinforced PU leather", which has excellent wear resistance, abrasion resistance, and aging resistance. It is a new generation of artificial leather that replaces genuine leather. With the deepening of the concept of animal protection and the continuous improvement of environmental protection requirements, microfiber leather has gradually replaced pure animal leather in various fields. At present, my country has become the world's largest producer of microfiber leather. By the end of 2008, there were 16 domestic microfiber leather enterprises with a total of 26 production lines and a production capacity of nearly 100 million meters. However, among the...
