Embodiment 1

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

[0029]

[0030] Secondly, the pure cotton fabric is uniformly padded, padded with the pretreatment working solution, and the pretreatment solution is evenly applied to the front and back sides, the fabric carrying rate is 70%, and dried at 105°C.

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

[0032] Finally, steam with saturated steam for 7 minutes at 102°C, wash with water, dry, and tenter.

[0033] The analysis of the double-sided printed fabric samples of pure cotton fabric shows that the front and back patterns of the fabric do not affect each other, and have high fineness, bright color, strong expressiveness, rich layering, soft hand feeling and good fastness. This fully demonstrates that the present invention ...

Embodiment 2

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

[0036]

[0037] Secondly, the Tencel fabric is evenly rolled, one dipped and one rolled, and the pretreatment working solution is applied to the front and back sides of the padding.

[0038] Then, ink-jet printing is carried out with reactive dye ink on the front of the fabric, and after drying at 90° C., ink-jet printing is carried out with reactive dye ink on the reverse side of the fabric, and dried at 90° C.

[0039] Finally, steam with saturated steam at 102°C for 14 minutes, wash with water, dry, and tenter.

[0040] The analysis of the double-sided printed fabric samples of Tencel fabric shows that there is a sheath and core layer in the Tencel fabric, which is quite different from the pure cotton fabric, and the formula composition of the pretreatment working solution needs to be adjusted. The front and back patterns of Tencel fabric do not affect each other, and have high...

Embodiment 3

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

[0043]

[0044] Secondly, the silk fabric is uniformly padded, one dipped and one rolled, and the pretreatment working solution is applied to both sides of the front and back of the padding.

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

[0046] Finally, steam with saturated steam for 7 minutes at 102°C, wash with water, dry, and tenter.

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 ...
