Embodiment 1

[0012] Dissolve 20g of sodium alginate into 479.6g of deionized water, stir to make it fully dissolved, and obtain the seaweed fiber spinning stock solution; take 0.4g of basic pink 6GDN, add it to the seaweed fiber spinning stock solution, stir to make it evenly mixed, Then high-pressure filtration (the filter membrane is a 100-mesh PP membrane) and vacuum degassing for 10 hours to obtain the lake dye seaweed fiber spinning solution. Adjust the temperature of the lake dye seaweed fiber spinning solution to 50°C, and extrude the spinning solution through the spinneret hole to a temperature of 20°C, CaCl 2 In the coagulation bath with a solubility of 2%, the primary seaweed fiber is obtained, and then the primary seaweed fiber is passed through a preheating bath and a drawing bath, and then stretched and shaped, and after drying and oiling, the lake dye colored seaweed fiber is obtained . The temperatures of the preheating bath and the drawing bath are 65° C. and 110° C., and ...

Embodiment 2

[0014] Dissolve 25g of sodium alginate into 473.75g of deionized water, stir to make it fully dissolved; take 1.25g of weak acid yellow 5G, add it to the seaweed fiber spinning stock solution, stir to make it evenly mixed, and then filter under high pressure (the filter membrane is 20 μm PP film), vacuum defoaming for 10 hours to obtain the lake dye seaweed fiber spinning solution. Adjust the temperature of the lake dye seaweed fiber spinning solution to 40°C, and extrude the spinning solution through the spinneret hole to a temperature of 40°C, CaCl 2 In a coagulation bath with a solubility of 5%, the primary seaweed fiber is obtained, and then the primary seaweed fiber is passed through a preheating bath and a drawing bath, and then stretched and shaped, and after drying and oiling treatment, the lake dye colored seaweed fiber is obtained . The temperatures of the preheating bath and the drawing bath are 40° C. and 70° C., and the drawing ratio of the seaweed fiber is 250%....

Embodiment 3

[0016] Dissolve 30g of sodium alginate into 469.4g of deionized water, stir to make it fully dissolved; take 0.6g of acid green 2G, add it to the seaweed fiber spinning stock solution, stir to make it evenly mixed, and then filter under high pressure (the filter membrane is 20 μm PP film), vacuum defoaming for 10 hours to obtain the lake dye seaweed fiber spinning solution. Adjust the temperature of the lake dye seaweed fiber spinning solution to 55°C, and extrude the spinning solution through the spinneret hole to a temperature of 50°C, CaCl 2 In the coagulation bath with a solubility of 4%, the primary seaweed fiber is obtained, and then the primary seaweed fiber is passed through the preheating bath and the drawing bath, and then stretched and shaped, and after drying and oiling, the colored lake algae fiber is obtained . The temperatures of the preheating bath and the drawing bath are 70° C. and 130° C., and the drawing ratio of the seaweed fiber is 110%.

Abstract

The invention discloses a method for coloring alginate fiber stoste by adopting lake colors, and belongs to the field of fine chemical engineering and material science. The method comprises the following steps: adding sodium alginate into deionized water, and stirring so as to dissolve sodium alginate fully to prepare alginate fiber spinning stoste; then adding lake colors into the alginate fiber spinning stoste, stirring and mixing uniformly, filtering and defoaming to obtain the lake color colored alginate fiber stoste, and preparing further to obtain lake color colored alginate fibers. The method overcomes the problem of damage of traditional dye dying on fibers; the prepared colored alginate fibers have the advantages of bright colors, high color fastness, good solvent mobility resistance and the like.

Description

technical field [0001] The invention relates to a method for coloring seaweed fiber stock solution with lake dye, belonging to the fields of fine chemical industry and material science. Background technique [0002] my country has a long coastline and is rich in seaweed resources. The effective development and use of these resources is of great significance to the development of our marine career. Seaweed fiber is a new type of green and environmentally friendly fiber derived from seaweed polysaccharides in natural seaweed. It has the characteristics of high absorption, high oxygen permeability, biodegradability and compatibility, and has great development value. Especially in recent years, as people's awareness of environmental protection has been strengthened day by day, the research on using seaweed fiber in the clothing industry is gradually rising. In order to realize the dyeing of seaweed fiber, relevant researchers and institutions at home and abroad have carried out...
