Example Embodiment

[0027] Example 1

[0028] First, prepare the pretreatment working solution according to the following formula.

[0029]

[0030] Secondly, the pure cotton fabric is evenly rolled, paddled with the pretreatment working fluid, and the pretreatment fluid is evenly applied on both sides, the fabric has a liquid rate of 70%, and is dried at 105°C.

[0031] Then, the front side of the pure cotton fabric is inkjet printed with reactive dye ink, dried at 105°C, and the reverse side of the fabric is inkjet printed with reactive dye ink, dried at 105°C.

[0032] Finally, saturated steam, steamed for 7 minutes at 102°C, washed with water, dried, and stretched.

[0033] Analyzing the double-sided printed cloth sample of pure cotton fabric, the pattern on the front and back of the fabric does not affect each other, with high fineness, bright color, strong expressiveness, rich layering, soft hand feeling and good fastness. This fully shows that the present invention has a good effect on double-side...

Example Embodiment

[0034] Example 2

[0035] First, prepare the pretreatment working solution according to the following formula.

[0036]

[0037] Secondly, the Tencel fabric is uniformly rolled, one padding, one padding, padding pretreatment working liquid, uniformly applying pretreatment liquid on both sides, the fabric has a liquid rate of 80%, and is dried at 95°C.

[0038] Then, the front side of the fabric is inkjet printed with reactive dye ink and dried at 90°C, and the reverse side of the fabric is inkjet printed with reactive dye ink and dried at 90°C.

[0039] Finally, saturated steam, steamed for 14 minutes at 102°C, washed with water, dried, and stretched.

[0040] Analyzing the double-sided printed fabric samples of Tencel fabrics, the Tencel fabric has a skin core layer, which is quite different from pure cotton fabrics, and needs to adjust the composition of the pretreatment working fluid. The front and back patterns of Tencel fabric do not affect each other, have high fineness, bright ...

[0041] Example 3

[0042] First, prepare the pretreatment working solution according to the following formula.

[0043]

[0044] Secondly, the silk fabric is uniformly rolled, one padding and the other rolling, padding the pretreatment working fluid, uniformly applying the pretreatment fluid to the front and back sides, the fabric has a liquid rate of 75%, and is dried at 85°C.

[0045] Then, the front side of the fabric is inkjet printed with reactive dye ink and dried at 85°C, and the reverse side of the fabric is inkjet printed with reactive dye ink and dried at 85°C.

[0046] Finally, saturated steam, steamed for 7 minutes at 102°C, washed with water, dried, and stretched.

Abstract

The invention discloses a reactive dye duplex printing method and belongs to the technical field of textile inkjet printing .The reactive dye duplex printing method comprises the steps that fabric is padded with a pretreatment working solution containing an opacifying agent and a penetrating preventing agent, the pretreatment working solution is uniformly applied to the front and back sides of the fabric, the fabric is dried, the front side of the fabric is subjected to inkjet printing with reactive dye ink and dried, then the back side of the fabric is subjected to inkjet printing with the reactive dye ink and dried, steaming is carried out for fixation, and washing, drying and tentering are carried out .The reactive dye duplex printing method is suitable for duplex printing of pure-spun or blended fabric made of cellulose fibers .The double-side floral designs of the fabric obtained after inkjet printing do not influence each other and are high in fineness, bright in color, high in expressive force and rich in layering sense .

Description

technical field [0001] The invention relates to a method for double-sided printing with reactive dyes, belonging to the technical field of textile inkjet printing. Background technique [0002] Double-sided printing fabrics such as tablecloths, shawls, silk scarves, flags, handkerchiefs, etc. can achieve completely different printing effects on both sides, and have broad market prospects. [0003] The production of double-sided printed fabrics by flat screen or rotary screen printing is to use printing paste to penetrate into the back of the fabric, so that the patterns on the front of the fabric penetrate into the reverse of the fabric, and then undergo steaming, washing or baking processes. However, the penetration performance of the color paste and the fineness of the pattern are a pair of contradictions. If the color paste penetrates into the back of the fabric, the fineness of the pattern will inevitably be reduced, so that only the double-sided same color pattern with ...
