Embodiment 1

[0027] The components and weight ratio of the acid dye ink are: strong acid dye 15%, polyamide resin 30%, ethanol 54%, organosilicon defoamer 0.5%, organosilicon leveling agent 0.5%.

[0028] Its preparation method is: put ethanol in a stirrer, slowly add polyamide resin (solid polyamide resin, its molecular weight is between 500-9000) at a temperature of 55 degrees, and slowly add polyamide resin until the resin is completely dissolved, and then add Silicone leveling agent, silicone defoamer, stir for 10 minutes, then slowly add acid dye, increase the stirring speed to 1500 rpm, stir for 45 minutes, test the viscosity of the color paste, add ethanol to adjust the viscosity to 1500 centimeters Poor (40 degrees). The resulting color paste is ground in a ball mill and kept grinding for 72 hours so that the fineness of the color paste is less than or equal to 1 micron. The resulting ink is released, and the viscosity is adjusted to 50 seconds with ethanol or a mixture of ethanol...

Embodiment 2

[0030] The components and weight ratio of the acid dye ink are: 20% of weak acid dye, 20% of binder, 59.4% of solvent, 0.3% of defoamer, and 0.3% of leveling agent.

[0031] Its preparation method is: put ethanol in a stirrer, slowly add polyamide resin (condensed from dimerized vegetable oil fatty acid and polyethylene polyamine) at a temperature of 45 degrees, and slowly add polyamide resin until the resin is completely dissolved, and then add Leveling agent, defoamer, stir for 5 minutes, then slowly add acid dye, increase the stirring speed to 1200 rpm, stir for 30 minutes, test the viscosity of the color paste, add ethanol to adjust the viscosity to 1300-1500 centipoise ( 40 degree). The resulting color paste is ground in a ball mill and kept grinding for 48 hours so that the fineness of the color paste is less than or equal to 1 micron. The resulting ink is released, and the viscosity is adjusted to 50 seconds with ethanol or a mixture of ethanol and methyl ethyl ketone,...

Embodiment 3

[0033] The components and weight ratio of the acid dye ink are: 15% of acid complex dye, 20.2% of polyamide resin, 64% of solvent, 0.4% of polyorganosiloxane, and 0.4% of polyether modified polyorganosiloxane.

[0034] The preparation method is: put the solvent in a stirrer, slowly add polyamide resin at a temperature of 50 degrees, and stir at a low speed until the resin is completely dissolved, then add polyorganosiloxane and polyether modified polyorganosiloxane, Stir for 8 minutes, then slowly add acid dye, increase the stirring speed to 1400 rpm, stir for 40 minutes, test the viscosity of the color paste, add ethanol to adjust the viscosity to 1300-1500 centipoise (40 degrees). The resulting color paste is ground in a ball mill and kept grinding for 60 hours, so that the fineness of the color paste is less than or equal to 1 micron. The resulting ink is released, and the viscosity is adjusted to 50 seconds with ethanol or a mixture of ethanol and methyl ethyl ketone, or d...

Abstract

The invention provides a wet-method transfer printing process of natural fiber and nylon, which mainly comprises the following steps: (1) selecting acidic printing ink or active printing ink; (2) printing: printing the surface of PET or BOPP film with the selected printing ink to obtain a transfer printed film; (3) transfer printing: treating natural fiber and nylon with a soaking liquid, subjecting the transfer printed film and printed fabric simultaneously to the compression by a rolling machine; and (4) oven-drying: oven-drying the fabric after the transfer printing is completed and baking to allow color fixation. The invention has the advantages of high transfer printing rate, high color yield of fabric, bright color, good color fastness, less pollution, reduced water consumption, simple process, high production efficiency, low cost, and success in non-paper transfer printing.

Description

technical field [0001] The invention relates to a fabric printing and dyeing method, in particular to a natural fiber and nylon wet transfer printing method. Background technique [0002] In the prior art, Chinese Patent No. 96108188.0 discloses a transfer printing pretreatment agent and printing process for natural fiber fabrics. By pre-treating natural fiber fabrics, closing the hydroxyl groups of natural fibers, and using the sublimation principle of disperse dyes, transfer printing is completed under high temperature conditions. The disadvantage of pretreatment is that a thermoplastic film is formed on the outer layer of the natural fiber fabric to accept disperse dyes or denature the natural fiber, which will make the natural fiber's moisture absorption, perspiration, and breathability worse, and affect the fastness and hand feel of the product. have a certain influence. Chinese Patent No. 200410041034.1 discloses a transfer printing of natural fiber fabrics, paper co...
