Problems solved by technology

Dyeing methods in the prior art cannot meet the above requirements
[0003] Simultaneously, the dyeing of non-woven fabric, yarn, fiber in the prior art exists the same problem as fabric dyeing, makes described non-woven fabric after dyeing, yarn, fiber ground color color monotonous, and color pattern is not abundant

Embodiment 1

[0024] Said cellulose fabric was dyed with 5 grams per liter of vat dye Vat Red 6B, and then 15 grams per liter of sulfur dye Sulfur Blue 3B. The soaping fastness of the dyed vat dyes is higher than that of the dyed sulfur dyes, so the red background color is not easy to be washed off when washing, and the blue surface color is easy to be washed off. The dyeing process conditions are all prior art, which will not be repeated here. After dyeing, the surface of the cellulose fabric is blue-purple, and finally the whole cellulose fabric is washed with enzyme water, that is, the enzyme solution with a mass percentage content of 1% is selected to wash the cellulose fabric with water at room temperature. After washing, the cloth surface shows red-purple-blue-purple and colors between the three colors. During the enzyme washing process, different parts of the cellulose fabric rub against each other, and because the soaping fastness of sulfur dyes is worse than that of the vat dyes, ...

Embodiment 2

[0026] First use 5 grams / liter of vat dye vat blue RSM to dye the base color of the cellulose non-woven fabric, and then use 20 grams / liter of sulfur dye sulfur red to dye the surface color of the cellulose non-woven fabric, and the dyed reduction The soaping fastness of the dye is higher than that of the dyed sulfur dye, so the blue background color is not easy to be washed off when washing, and the red surface color is easy to be washed off. The dyeing process conditions are all prior art, which will not be repeated here. Finally, part of the cellulose non-woven fabric is stone-washed, and the stone washing refers to adding a certain size of pumice stone to the water for washing the cellulose non-woven fabric, so that the pumice stone and the cellulose non-woven fabric are polished, and the water level in the grinding tank is polished. Carry out with the low water level that described cellulose non-woven fabric is fully soaked, so that pumice stone can contact with described...

Embodiment 3

[0028] First use 5 grams / liter of vat dye vat blue RSM to dye the base color of the cellulose yarn, then use 18 grams / liter of sulfur dye Sulfur Brown 5G to dye the cellulose yarn with an intermediate color, and finally use the coating Red 8119 stains the cellulosic yarn. The soaping fastness of the dyed vat dye is higher than that of the dyed sulfur dye, and the soaping fastness of the sulfur dye is higher than that of the paint. Therefore, the blue background color is the most difficult to be washed off when washing, and the red surface color is the most easy to be washed off. The dyeing process conditions are all prior art, which will not be repeated here. For the enzyme stone washing of the dyed cellulose yarn, the mass percentage content of the enzyme in the enzyme solution is 0.5%, and the cloth surface after washing shows: blue-yellow-red and colors in between . The color of said cellulose yarn after enzyme stone washing is richer due to the addition of a layer of in...

Abstract

The invention relates to a dyeing method, which comprises the following steps: (1) cellulose fiber or a cellulose fiber product is dyed with ground color; (2) the cellulose fiber or the cellulose fiber product dyed with the ground color is dyed with surface color which is different from the color of the ground color, and the soaping fastness of the surface color is lower than that of the ground color; and (3) one or the combination of more methods of ferment water wash, stone wash and ferment stone wash is adopted to wash. The ground color of the obtained cellulose fiber or cellulose fiber product has a plurality of kinds of selectable colors as well as old and fashionable appearance. The method overcomes the defect that the ground color can only be single white in the prior art.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing method of cellulose fibers and cellulose fiber products. Background technique [0002] In the prior art, in order to give the fabric a "faded" or "old" fashion appearance, the common method is to pre-dye the fabric and then wash it with enzymes to obtain the above-mentioned effect, and obtain the base color of the fabric and the dyed color. Fabric in two colors. For example, dyeing denim with indigo dye, and then washing with enzyme water, the denim will show two colors of white and blue. The above-mentioned treatment method in the prior art gives the fabric an old appearance and increases the old fashion sense of the fabric. Although the above-mentioned prior art can obtain different surface colors by selecting different dyes, the background color is always monotonous white and cannot be changed. In practice, based on the needs of fash...
