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. 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 sulfur dyes, the parts of th...
Embodiment 2
[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 described cellulose non-wo...
Embodiment 3
[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 cellulose yarn, and comprehens...
