Abstract

The invention relates to a hydrogel type alginate fiber film cloth, and also relates to a production method of the hydrogel type alginate fiber film cloth. The production method of the hydrogel type alginate fiber film cloth comprises the following steps: (1) preparing a sodium alginate spinning solution; (2) performing wet spinning on the spinning solution in a coagulation bath; (3) preparing anaqueous sodium alginate solution having a mass fraction of 20-30%; (4) immersing calcium alginate nascent fibers in the aqueous sodium alginate solution having the mass fraction of 20-30%; (5) squeezing out water, immersing the nascent fibers in an ethanol-water solution, and squeezing out water; (6) preparing a chitosan solution having a mass fraction of 2%; (7) immersing the hydrogel type seaweed fibers obtained in step (5) in the chitosan solution; and (8) squeezing out water, and performing dying and winding processes to obtain the hydrogel type alginate fiber film cloth. The hydrogel typealginate fiber film cloth has a high strength, can be rapidly aggregated when meeting water, and can be applied to the field of hydrogel masks.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a hydrogel-type alginate fiber membrane cloth, and also to a preparation method of the hydrogel-type alginate fiber membrane cloth. Background technique [0002] Seaweed fiber is a new type of high-performance fiber obtained by wet spinning production process using polysaccharide extracted from natural seaweed as raw material, water-soluble metal salt solution as coagulation bath, and can be used as green fiber. Seaweed fiber products have good health care, medical and beauty functions. Seaweed has accumulated rich minerals in the ocean, and contains carbohydrates, amino acids, fats and various vitamins, which can activate cell metabolism and have the functions of anti-inflammatory and anti-itching, so seaweed fiber has natural maintenance for human skin , Moisturizing, beauty effect. Seaweed fiber also has high hygroscopicity, and the thinner base fabric can absorb more essence and bet...
