Problems solved by technology

The connecting material in printing ink is usually called resin. Chinese patent 200810196039.X provides a variety of polymer resins that can be used for the connecting material of wet transfer dye gravure ink. Although the resin part provided has It must be hot-melt, but not water-soluble. Although the printing ink composed of them can be transferred to the fabric well during heat transfer, it cannot be removed by washing, causing the pattern to feel hard.
And because there is no water solubility, the dye cannot be completely released during steaming or cold stacking, resulting in light color, high dye concentration in wastewater, and easy staining on the white background
Therefore, in the prior art, this layer of dense dye layer will isolate the hot-melt coating during high-temperature thermal transfer, so that the dye cannot be well attached to the fiber and affect the effect of transfer printing.
Or on the final product, because the resin is not water-soluble, it cannot be removed by washing, causing the finished product to feel hard and lose its use value

Embodiment 1

[0075] Take weak acid Brilliant Red B, 1000 grams, put it into 5000 grams of hot water to dissolve, stir, after it is completely dissolved, heat, and add 2000 grams of water-soluble polyamide hot-melt resin, stir, after the resin is completely dissolved, add the remaining 5000 grams of water, adjust the viscosity to 5000mPa.s, so that it is prepared as ink for flat screen printing.

[0076] Use a flat screen printing machine to select the pattern, print the above ink on the BOPP film, and dry it. The reprinted surface is attached to the silk fabric that has been wetted and dried with a mixed aqueous solution of 8% (w / w) glycerin and 2% (w / w) ammonium sulfate. The temperature is 120°C and the pressure is 25Kg / cm 2 The flatbed press transfer. Then tear off the film, put it into a steam box, and steam for 30 minutes at a temperature of 105°C. Finally, after washing and drying, the printed product is finished.

[0077] Through the test, the fastness indicators of the printed p...

Embodiment 2

[0081] Take 1300 grams of vat green FFB, add 6000 grams of water, put it into a ball mill and grind for 48 hours, test the fineness, after the fineness is less than 5 microns, add 4000 grams of water, 2500 grams of water-soluble polyvinyl alcohol hot-melt resin, continue grinding, When the resin is completely dissolved and the fineness of the dye is less than 2 microns, add the remaining 2000 g of water to adjust the viscosity to 6500 mPa.s, so that the ink for rotary screen printing is prepared.

[0082] Select the pattern, print the above-mentioned ink on the PET film with a rotary screen printing machine, and dry it. Then the printed surface is attached to the cotton fabric that has been wetted and dried with a mixed aqueous solution composed of 8% glycerin, 2% (w / w) sodium carbonate and 10% (w / w) white powder, and placed in The temperature is 110°C and the pressure is 15Kg / cm 2 The flatbed press transfer. Then tear off the film, put it into a steam box, and steam for 15 ...

Embodiment 3

[0087] Take Reactive Brilliant Red M-2B, 700 grams, put it into 3000 grams of dimethyl sulfoxide to dissolve, stir, after it is completely dissolved, add 1500 grams of water-soluble polyester hot-melt resin, stir, after the resin is completely dissolved, add 2500 Gram water, adjust the viscosity to be (25 ℃) 17s (Za En No. 3 cup), so just dubbed the ink for gravure printing.

[0088] Use water-soluble polyester hot-melt resin as the solute, water and dimethyl sulfoxide mixture as the solvent, apply the solution to the PET film, select the pattern, and print the above ink on the coated PET film with a gravure printing machine ,drying. The re-printed surface is attached to the cotton fabric that has been wetted with a mixed aqueous solution composed of 12% (w / w) urea and 2% (w / w) sodium carbonate, and dried. The temperature is 150°C, and the pressure is 10Kg / cm 2 The pass-through press transfer. Then put it into a steam box together with the film, and steam for 15 minutes at ...

Abstract

The invention discloses a fabric pattern transfer ink which comprises the following components in percentage by weight: 0.1-40wt% of dye, 1-50wt% of binder and 10-98.9wt% of solvent, wherein the binder is water-soluble hot-melt resins, and the solvent is water, or an organic solvent or a mixture of the water and organic solvent. The invention also discloses a preparation method of the fabric pattern transfer ink, a fabric pattern transfer method using the ink and a fabric pattern transfer film. Compared with the prior art, large-scale industrial production of the heat transfer printing film or heat transfer printing paper of a fabric is possible through the invention, the production cost is greatly reduced, the production efficiency is remarkably improved, and the comprehensive popularization of the technology is facilitated. Moreover, the coating thickness of the prior art is also reduced, even the coating process can be saved, the equipment investment cost is lowered, and the manufacturing process is shortened.

Description

technical field [0001] The invention belongs to the field of fabric printing and dyeing, and in particular relates to a fabric pattern transfer ink and a preparation method thereof. Background technique [0002] The traditional textile thermal transfer printing method began in the late 1960s. It is a printing method that first prints easily sublimable disperse dyes on the transfer base paper, and then transfers the disperse dyes to the fabric by hot pressing to form a pattern. It has the advantages of realistic flower pattern, simple process, less discharge of three wastes and so on. It is only suitable for printing on polyester fabrics and does not work well on nylon, acrylic, and natural fiber fabrics. [0003] In order to realize the transfer printing of natural fibers, the wet transfer printing of reactive dyes and acid dyes has attracted the attention of many printing and dyeing workers at home and abroad. Patent No. 200410041034.1 and Patent No. 200510026661.2 each ...
