Embodiment 1

[0025] The dye Y-1 structure used is shown below:

[0026]

[0027] Weigh 0.5 g of dye Y-1 and dissolve it in 500 g of water to prepare the dye solution. Then use 5% hydrochloric acid solution to adjust the pH value of the dye solution to 4.5. Put 25 grams of calcium alginate fibers in the dyeing solution, raise the temperature of the dyeing solution to 40° C., and then dye for 50 minutes. After dyeing, take out the fiber and soak it in a neutral soap solution containing 4‰ at 95°C for 10 minutes. After taking out the fiber, wash it fully and dry it in the air.

Embodiment 2

[0029] The structure of the dye Y-2 used is described below:

[0030]

[0031] Weigh 0.5 g of dye Y-2 and dissolve it in 800 g of water to prepare the dye solution. Then use 5% hydrochloric acid solution to adjust the pH value of the dye solution to 3.5. Put 50 grams of calcium alginate fibers in the dyeing solution, raise the temperature of the dyeing solution to 30°C, and then dye for 30 minutes. After dyeing, take out the fiber and soak it in a neutral soap solution containing 4‰ at 95°C for 10 minutes. After taking out the fiber, wash it fully and dry it in the air.

Embodiment 3

[0033] The structure of the dye R-1 used is described below:

[0034]

[0035] Weigh 0.5 g of dye R-1 and dissolve it in 800 g of water to prepare the dye solution. Then use 5% hydrochloric acid solution to adjust the pH value of the dye solution to 5. Put 50 grams of calcium alginate fibers in the dyeing solution, raise the temperature of the dyeing solution to 50°C, and then dye for 50 minutes. After dyeing, take out the fiber and soak it in a neutral soap solution containing 4‰ at 95°C for 10 minutes. After taking out the fiber, wash it fully and dry it in the air.

Abstract

The invention belongs to the technical field of fiber dyeing, in particular to a method for dyeing calcium alginate fiber. The method for dyeing the calcium alginate fiber of the present invention is to dye the calcium alginate fiber with the dyestuff containing polyethylene polyamine skeleton structure. The invention fundamentally avoids the disadvantage of fiber damage caused by adding inorganic salts to promote dyeing in the traditional dyeing process, and the strength loss of the fiber after dyeing is small; The interaction between the dye molecule and the fiber is stronger, so that it has the advantages of higher dyeing rate and soaping fastness. The color of the dyed fiber is uniform and bright, which meets the requirements of seaweed. Calcium acid fiber dyeing requirements, is an energy-saving and environmentally friendly dyeing method.

Description

technical field [0001] The invention belongs to the technical field of fiber dyeing, in particular to a method for dyeing calcium alginate fiber. Background technique [0002] Calcium alginate fiber is a new type of biodegradable synthetic fiber. The raw material of this type of fiber comes from the natural sodium alginate contained in algae plants in the ocean, and is prepared by wet spinning process. This type of fiber not only has the characteristics of hygroscopicity, softness, heat preservation and biocompatibility of traditional natural fibers, but also has excellent flame retardant, antistatic and antibacterial properties due to its special structure and preparation process, so it has a very wide range of applications. industrial application prospects. [0003] However, the main uses of calcium alginate fiber at this stage are still concentrated in non-clothing fields such as medical dressings and masks, mainly due to the difficulty in dyeing and finishing of this t...
