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 relea

Embodiment 1

[0075] Take weak acid brilliant red B, 1000 grams, dissolve it in 5000 grams of hot water, stir, after it is completely dissolved, heat it, 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 as to prepare the ink for flat screen printing.

[0076] Select the pattern with a flat screen printing machine, print the above ink on the BOPP film, and dry. The re-printed surface is attached to the silk fabric that has been wetted and dried with a mixed aqueous solution composed of 8% (w / w) glycerin and 2% (w / w) ammonium sulfate, and the temperature is 120°C and the pressure is 25Kg / cm 2 flat iron transfer. Then tear off the film, put it in a steaming 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 indexes of the printed pattern are shown...

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, the remaining 2000 water is added to adjust the viscosity to 6500 mPa.s, thus making the ink for rotary screen printing.

[0082] Select the pattern, print the above ink on the PET film with a rotary screen printing machine, and dry it. The re-printed surface is attached to the cotton fabric that has been wetted and dried with a mixed aqueous solution composed of 8% glycerol, 2% (w / w) sodium carbonate and 10% (w / w) hanging white blocks, and is placed in The temperature is 110℃, the pressure is 15Kg / cm 2 flat iron transfer. Then tear off the film, put it in a steaming box, and steam for 15 minutes at a tempera...

Embodiment 3

[0087] Take reactive brilliant red M-2B, 700 grams, dissolve it in 3000 grams of dimethyl sulfoxide, 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 grams grams of water, adjust the viscosity to (25 ° C) 17s (Zahn No. 3 cup), so that the gravure printing ink is prepared.

[0088] Taking the water-soluble polyester hot-melt resin as the solute, and the mixed solution of water and dimethyl sulfoxide as the solvent, the solution is coated with a PET film, the pattern is selected, and the above-mentioned ink is printed on the coated PET film with a gravure printing machine. ,drying. The reprinted surface is attached to the cotton fabric that has been wetted and dried with a mixed aqueous solution composed of 12% (w / w) urea and 2% (w / w) sodium carbonate. The temperature is 150°C, and the pressure is 10Kg / cm 2 of a pass-through ironer transfer. Then it was put into a steaming...

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, in particular to a fabric pattern transfer ink and a preparation method thereof. Background technique [0002] The traditional thermal transfer printing method for textiles began in the late 1960s. It is a printing method in which the easily sublimated disperse dyes are first printed on the transfer backing paper, and then the disperse dyes are sublimated and transferred to the fabric by hot pressing and other methods to form patterns. It has the advantages of realistic pattern, simple process, less discharge of three wastes and so on. It is only suitable for printing on polyester fabrics, and it 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. 200410...
