Abstract

The invention relates to a water-soluble alginate antibacterial fiber and a preparation method thereof. The preparation method comprises: weighing a water-soluble polymer and dissolving the water-soluble polymer in distilled water, and then adding nano-silver-loaded zirconium phosphate and / or nano-zinc oxide, and carrying out uniform ultrasonic dispersion; weighing sodium alginate and dissolving sodium alginate in the mixed liquor, stirring and heating to obtain a spinning solution; defoaming the spinning solution, metering and ejecting from a spinneret plate into a coagulating bath by a metering pump; preparing a sodium ethylene diamine tetracetate solution; squeezing fiber to remove water, and immersing in the sodium ethylene diamine tetracetate aqueous solution; adding sodium carbonateand sodium bicarbonate and fully mixing, and continuously immersing; preparing a chitosan solution; squeezing fiber to remove water, and immersing in the chitosan solution; squeezing fiber to remove water, drying, and winding. The invention has the advantages as follows: the product is soluble in water; active ingredients are easy to absorb, and the antibacterial effect is good; the disadvantage that traditional water-soluble fiber has low strength and is easy to fracture is dissolved; and the product has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to a water-soluble alginate antibacterial fiber and a preparation method thereof. Background technique [0002] Water-soluble fiber can be dissolved in water or slowly hydrolyzed into water-soluble molecules (or compounds) when encountering water. It is a valuable functional differentiated fiber and can be used in papermaking, medical non-woven fabrics, and female sanitary napkins. However, the existing water-soluble fibers have problems such as low strength and easy breakage during use, which limits the application range of water-soluble fibers. [0003] Seaweed fiber is a new type of high-performance fiber obtained by wet spinning production process with polysaccharide extracted from natural seaweed as raw material and water-soluble metal salt solution as coagulation bath. Because seaweed has accumulated rich minerals in the ocean, and contains ingredients...
