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...

[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.
