Abstract

The invention relates to the technical field of functional renovation of alginate fibers, in particular to an aquagel alginate fiber and a preparation method for the same. The preparation method for the aquagel alginate fiber comprises the following steps: (1) extracting a sodium alginate raw material from algae; (2) preparing an 8 to 10 mass percent aqueous solution of the alginate, and performing defoaming to obtain an alginate spinning solution; (3) preparing a mixed solution of an aqueous solution of soluble starch and the alginate spinning solution; (4) enabling the mixed solution obtained in step (3) to pass through a metering pump, and extruding the mixed solution into a first coagulating bath from a spinneret plate; (5) introducing as-spun fibers into a second coagulating bath; (6) introducing the fibers into a third coagulating bath, performing drawing forming, squeezing water out, and performing washing and drying to a constant weight, so as to obtain the aquagel alginate fibers. According to the aquagel alginate fiber and the preparation method, a preparation process is improved to improve the strength and the spinnability of the alginate fibers and shorten the gelation time, and the prepared aquagel alginate fiber can be used for preparing medical sanitary dressings and skin-care facial masks.

Description

technical field [0001] The invention relates to the technical field of functional transformation of seaweed fibers, in particular to a hydrogel seaweed fiber, and also to a preparation method of the hydrogel seaweed fiber. Background technique [0002] There are many kinds of seaweed. Alginic acid is the main component of alginate, which exists in the stems and leaves of seaweed (about 10-20% of which is crude protein, crude fat, crude cellulose, water and impurities, etc.). 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. [0003] Seaweed fiber products have good health care and medical functions. Through the exchange of calcium ions and human sodium ions, it can promote the wound to produce sodium alginate and calcium alginate gel. This gel is hydrophilic and can inhibit ...
