Example Embodiment

[0023] Embodiment one:

[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. The red background color is not easy to be washed off when washing, and the blue surface color is easy to be washed off. After dyeing, the surface of the cellulose fabric is blue-purple. Among them, the aforementioned dyeing process and conditions are common methods in printing and dyeing factories, and will not be repeated here. Finally, the whole cellulose fabric is washed with enzyme water, that is, an enzyme solution with a mass percentage of 1% is selected for washing 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. Due to the poor wear resistance of su...

Example Embodiment

[0026] Embodiment two:

[0027] First use 5 grams per liter of vat dye vat blue RSM to dye the base color of the cellulose nonwoven fabric, and then use 20 grams per liter of sulfur dye sulfur red to dye the surface color of the cellulose nonwoven fabric. The soaping fastness of the dyed vat dyes is higher than that of the dyed sulfur dyes, 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. 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 cellulose non-woven fabric well, and then make the surface of ...

Example Embodiment

[0029] Embodiment three:

[0030] First use 5 grams per liter of vat dye vat blue RSM to dye the base color of the cellulose yarn, then use 18 grams per liter of sulfur dye sulfur yellow brown 5G to dye the intermediate color of the cellulose yarn, and finally use paint red 8119 Surface dyeing of said 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 paint. That is, when washing with water, the base color is the most difficult to fade, the red base color is not easy to be washed off, and the blue surface color is easy to be washed off. 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 enzyme stone washing refers to adding a certain amount of enzyme and pumice to the water for washing the ce...

Abstract

The invention relates to a dyeing method, which comprises the following steps: (1) fiber or a fiber product is dyed with ground color; (2) the fiber or the 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 fiber or the fiber product. The surface of the fiber or the fiber product shows a plurality of kinds of different colors after the washing, thereby overcoming the defect that the ground color is single white in the prior art, and ensuring that the fiber or the fiber product obtained by the method has natural color change and fashionable old appearance.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing method. 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, denim is dyed with indigo dye, and after being washed 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 fashion design, the fabric often requires diff...
