Example Embodiment

[0023] Example one:

[0024] Use 5 g / L of vat dye Vat Red 6B to dye the base color of the cellulose fabric, and then use 15 g / L of sulfur dye Sulfur Blue 3B. The soaping fastness of dyed vat dyes is higher than that of dyed sulfur dyes, so the red background color is not easy to be washed off during washing, and the blue surface color is easily washed off. The dyeing process conditions are all the 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 water, that is, an enzyme solution with a mass percentage of 1% is selected to wash the cellulose fabric with water at room temperature. The cloth surface after washing shows red-purple-blue-purple and a color between the three colors. During the enzyme washing process, different parts of the cellulose fabric rub against each other. Due to the poorer soaping fastness of sulfur dyes than the vat dyes, the parts of the cellulose...

Example Embodiment

[0025] Embodiment two:

[0026] First dye the base color of the cellulose non-woven fabric with 5 g / L vat dye Vat Blue RSM, and then dye the surface color of the cellulose non-woven fabric with 20 g / L sulfur dye Sulfur Red. The soaping fastness of dyes is higher than that of dyed sulfur dyes, so the blue background color is not easy to be washed off during washing, and the red surface color is easy to wash off. The dyeing process conditions are all the prior art, which will not be repeated here. Finally, part of the cellulose non-woven fabric is stone washed. The stone washing refers to adding a certain size of pumice stone to the water used for washing the cellulose non-woven fabric to polish the pumice stone and the cellulose non-woven fabric to polish the water level in the tank. It is carried out at a low water level at which the cellulose non-woven fabric is completely soaked, so that the pumice stone can be well in contact with the cellulose non-woven fabric, so that the sur...

Example Embodiment

[0027] Embodiment three:

[0028] First dye the cellulose yarn with 5 g / L vat dye Vat Blue RSM for the base color, then use 18 g / L sulfur dye Sulfur Yellow Brown 5G to dye the cellulose yarn with the intermediate color, and finally use paint Red 8119 dyes the cellulose 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 coating. Therefore, the blue background color is the least likely to be washed off during washing, and the red surface color is the easiest to be washed off. The dyeing process conditions are all the prior art, which will not be repeated here. For the dyed cellulose yarn enzyme stone washing, the mass percentage of the enzyme in the enzyme solution is 0.5%, and the cloth surface after washing shows: blue-yellow-red and a color between the three . Due to the addition of a layer of intermediate color, the color of the cellulose yarn after enzyme stone washing ...

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...
