Embodiment 1

[0120] Prepare a five-membered ring quaternary ammonium salt polymer solution with a mass percentage of 1%, put the seaweed fiber to be dyed into the above-mentioned modifier aqueous solution according to the bath ratio of 1:20, shake it at 20°C for 10 minutes, and then rinse it for use. Weigh the direct scarlet 4BS according to 3% of the seaweed fiber mass, prepare the dye liquor according to the bath ratio of 1:20, wait for the temperature of the dye liquor to rise to 40°C, put the pretreated seaweed fiber into the dye liquor, and then raise the temperature of the dye liquor To 80 ℃, dyeing treatment for 40 minutes. Then prepare a five-membered ring quaternary ammonium salt polymer solution with a concentration of 1 g / l as a color-fixing solution, and perform color-fixing according to a liquor ratio of 1:30. Put the dyed seaweed fiber into the above-mentioned color-fixing agent aqueous solution, fix the color at 60°C for 30 minutes, then soak the seaweed fiber after the colo...

[0122] Prepare a five-membered ring quaternary ammonium salt polymer solution with a mass percentage of 3%, put the seaweed fiber to be dyed into the above-mentioned modifier aqueous solution according to the bath ratio of 1:30, shake it at 30°C for 20 minutes, and then rinse it for use. Weigh Acid Blue 80 according to 3% of the seaweed fiber mass, prepare a dye liquor according to a bath ratio of 1:20, wait for the temperature of the dye liquor to rise to 30°C, put the pretreated seaweed fiber into the dye liquor, and then raise the temperature of the dye liquor To 95 ℃, dyeing treatment for 60 minutes. Then prepare a five-membered ring quaternary ammonium salt polymer solution with a concentration of 1 g / l as a color-fixing solution, and perform color-fixing according to a liquor ratio of 1:30. Put the dyed seaweed fiber into the above-mentioned color-fixing agent aqueous solution, fix the color at 60°C for 30 minutes, then soak the seaweed fiber after the color-fixation tre...

Embodiment 3

[0124] Prepare a 5-membered ring quaternary ammonium salt polymer solution with a mass percentage of 5%, put the seaweed fiber to be dyed into the above-mentioned modifier aqueous solution according to the bath ratio of 1:40, shake it at 30°C for 30 minutes, and then rinse it for use. Weigh reactive yellow KN-R according to 3% of the mass of seaweed fiber, and prepare a dye solution according to a bath ratio of 1:20. When the temperature of the dye solution rises to 30°C, put the pretreated seaweed fiber into the dye solution, and then put the dye solution into the dye solution. The temperature of the liquid was raised to 60° C., and the dyeing treatment was carried out for 50 minutes. Then prepare a five-membered ring quaternary ammonium salt polymer solution with a concentration of 2 g / l as a color-fixing solution, and perform color-fixing according to a bath ratio of 1:30. Put the dyed seaweed fiber into the above-mentioned color-fixing agent aqueous solution, fix the color...

Abstract

The invention discloses alginate fiber and a dyeing method thereof, and belongs to the technical field of textile fabric dyeing. The dyeing method of the alginate fiber comprises the following steps of S10, pretreating the alginate fiber by adopting a five-membered ring quaternary ammonium salt polymer; S20, dyeing the alginate fiber obtained in the step S10 by adopting a dye; and S30, carrying out color fixation treatment on the alginate fiber obtained in the step S20 by adopting the five-membered ring quaternary ammonium salt polymer. The alginate fiber obtained through the method is relatively high in dye-uptake rate, small in fiber strength damage and relatively high in soaping fastness.

Description

technical field [0001] The application belongs to the technical field of textile fabric dyeing, and in particular relates to a seaweed fiber and a dyeing method thereof. Background technique [0002] Seaweed fiber is a new type of green biodegradable fiber made from sodium alginate extracted from natural seaweed through wet spinning process. It has been valued for its excellent hygroscopic properties, film-forming and fiber-forming properties, as well as good biodegradability and biocompatibility. [0003] Seaweed fiber has been widely used in the field of medical dressings, and it also has great potential in high-end clothing, underwear fabrics and decorative textiles. [0004] The smooth feel of seaweed fiber brings wearing comfort, but also brings difficulty in spinning. On the one hand, it is still difficult to realize purely spun seaweed fiber yarns in the related art. On the other hand, because the current price of seaweed fiber is still slightly higher, so there ar...
