Problems solved by technology

Especially in the process of dyeing with traditional dyes, there are still defects such as low coloring rate, few types of dyes, and damage to fibers.
Compared with traditional dyeing, the dyeing process is more complicated, and results in the use and waste of a large amount of auxiliaries

Embodiment 1

[0025] The structure of the dye Y-1 used is as follows:

[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 a 5% hydrochloric acid solution to adjust the pH of the dye solution to 4.5. Put 25 grams of calcium alginate fiber in the dye solution, and heat the dye solution to 40°C, and then dye for 50 minutes. After dyeing, the fiber is taken out and immersed in a neutral soap solution containing 4‰ and saponified at 95°C for 10 minutes. After the fiber is taken out, it is thoroughly washed with water and dried.

Embodiment 2

[0029] The structure of the dye Y-2 used is as follows:

[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 a 5% hydrochloric acid solution to adjust the pH of the dye solution to 3.5. Place 50 grams of calcium alginate fiber in the dye solution, and heat the dye solution to 30°C, and then dye for 30 minutes. After dyeing, the fiber is taken out and immersed in a neutral soap solution containing 4‰ and saponified at 95°C for 10 minutes. After the fiber is taken out, it is thoroughly washed with water and dried.

Embodiment 3

[0033] The structure of the dye R-1 used is as follows:

[0034]

[0035] Weigh 0.5 g of dye R-1 and dissolve it in 800 g of water to prepare the dye solution. Then adjust the pH of the dye solution to 5 with 5% hydrochloric acid solution. Put 50 grams of calcium alginate fiber in the dye solution, and heat the dye solution to 50°C, and then dye for 50 minutes. After dyeing, the fiber is taken out and immersed in a neutral soap solution containing 4‰ and saponified at 95°C for 10 minutes. After the fiber is taken out, it is thoroughly washed with water and dried.

Abstract

The invention belongs to the technical field of fiber dyeing, and particularly relates to a dyeing method for calcium alginate fibers. According to the dyeing method for the calcium alginate fibers, dye containing polyethylene polyamine framework structures is adopted to dye the calcium alginate fibers; the defect that the fibers are damaged due to the fact that inorganic salt needs to be added for dyeing accelerating in the dyeing process of traditional dye is fundamentally overcome, and the strength loss of the fibers after dyeing is small; meanwhile, compared with the weaker intermolecular force and hydrogen-bond interaction between general direct dye and the fibers, the acting force between molecules of the dye and the fibers is higher, and then the advantages of being higher in dye-uptake rate and soaping fastness and the like are achieved; the dyed fibers are uniform and bright in color and meet the dyeing requirements of the calcium alginate fibers, and the dyeing method is economical in energy and environmentally friendly.

Description

Technical field [0001] The invention belongs to the technical field of fiber dyeing, and specifically relates to a method for dyeing calcium alginate fibers. 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 the algae plants in the ocean, and is prepared by a wet spinning process. This type of fiber not only has the characteristics of moisture absorption, 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, and thus has a very wide range of The prospects of industrial application. [0003] However, the main uses of calcium alginate fiber at this stage are still concentrated in non-clothing fields such as medical dressings, masks and other industries, mainly due to the difficulty of ...
