Problems solved by technology

Traditional discharge printing is realized by screen or paint printing, the process is cumbersome, and the amount of slurry is too large to cause water pollution, and these printing methods limit the characteristics of discharge printing to a certain extent, such as fine patterns, rich layers, and clear outlines.

Embodiment 1

[0029] The formula of the sizing agent is as follows in terms of weight percentage: 0.5% sodium alginate is used as a thickener, 6% urea is used as a moisture absorbing agent, 1% sodium bicarbonate is used as an acid-base agent, and water is added to make up to 100%. Stir fully until the sodium alginate is fully swollen, and all components are completely dissolved and evenly dispersed. The dyed silk fabric is padded with sizing solution and then dried, and the fabric is sprayed with white ink by an inkjet printer, and dried at room temperature. Then steaming is carried out, the steaming temperature is 100° C., the steam saturation is 98%, and the time is 10 minutes. After the steaming is completed, the fabric is washed with water to obtain the ink-jet discharge printed fabric. After testing, the whitening area: the whiteness is 89.17; the non-whitening area: the dry rubbing fastness can reach grade 5, the wet rubbing fastness can reach grade 4-5, and the washing fastness can ...

Embodiment 2

[0038] The formula of the sizing agent is as follows: the thickener is 2% sodium carboxymethyl cellulose, the hygroscopic agent is 8% urea, the acid-base agent is 2% sodium bicarbonate, and water is added to make up to 100%. Stir fully until the sodium alginate is fully swollen, and all components are completely dissolved and evenly dispersed.

[0039] The dyed cotton fabric is dried after padding with sizing solution, and the fabric is sprayed with white ink by an inkjet printer, and dried at room temperature. Then carry out steaming, the steaming temperature is 102° C., the steam saturation is 98%, and the time is 12 minutes. After the steaming is completed, the fabric is washed with water to obtain the ink-jet discharge printed fabric. After testing, the undrawn area: the dry rubbing fastness can reach 4~5 grades, the wet rubbing fastness can reach 4 grades, and the washing fastness can reach 3~4 grades. The test results are shown in Table 2.

Embodiment 3

[0045] The formula of the sizing agent is as follows: 5% sodium alginate is used as a thickener, 2% urea is used as a hygroscopic agent, 3% ammonium sulfate is used as an acid-base agent, and water is added to make up to 100%. Stir fully until the sodium alginate is fully swollen, and all components are completely dissolved and evenly dispersed.

[0046] The dyed wool fabric is padded with sizing solution and then dried, and the fabric is sprayed with white ink by an inkjet printer, and dried at room temperature. Then carry out steaming, the steaming temperature is 101° C., the steam saturation is 98%, and the time is 15 minutes. After the steaming is completed, the fabric is washed with water to obtain the ink-jet discharge printed fabric. After testing, the whitening area: the whiteness is 80.02; the non-whitening area: the dry rubbing fastness can reach grade 5, the wet rubbing fastness can reach grade 4-5, and the washing fastness can reach grade 3-4.

Abstract

The invention relates to a method for preparing a fabric through inkjet and discharge printing. The preparation method comprises the following steps: S1, preparing discharge printing ink; S2, sizing a dyed fabric; S3, adding the discharge printing ink prepared in S1 into an ink-jet printer and carrying out ink jetting on the fabric obtained in S2 in an ink jetting manner; and S4, subjecting a product of S3 to steaming. The method provided by the invention integrates discharge printing and inkjet printing, so full play is given to the characteristics of delicateness, verisimilitude, hierarchy, brilliant and plump colors, sharp color contrast, edge sharpness, plump ground color, etc. of patterns obtained after white discharging.

Description

technical field [0001] The invention relates to a preparation method of ink-jet discharge printing fabric. Background technique [0002] Discharge printing is printing on the dyed fabric. The printing paste (printing paste) contains a chemical substance (called whitening agent) that can destroy the dyeing dye, and the printing method of destroying or decolorizing the ground color dye at the printing place. . The pattern of discharge dyeing printing has the characteristics of meticulous, lifelike, rich layers, plump and gorgeous, strong color contrast, clear outline, and full background color. Traditional discharge printing is realized by screen or paint printing, the process is cumbersome, and the amount of slurry is too large to cause water pollution, and these printing methods limit the characteristics of discharge printing to a certain extent, such as fine patterns, rich layers, and clear outlines. . [0003] In view of the above-mentioned defects, the designers are ac...
