[0014] Example

[0015] The preparation method of the medical gauze with antibacterial effect of the present invention is that the medical gauze is blended from seaweed fiber, chitin fiber and cotton fiber, and the weight ratio of the seaweed fiber, chitin fiber and cotton fiber is 30-35:40 -50: 75-85; the preparation method is as follows: 1) spray the modified solution on the stacked chitin fibers, and modify for 12-24 hours; 2) add sodium alginate to deionized water, stir at room temperature until completely Dissolve to obtain a sodium alginate solution with a mass percentage of 2.4-3.6, add nano-silver particles to the sodium alginate solution, stir evenly, and make a mixed spinning solution, use wet spinning technology to prepare seaweed fibers, and pull them after coagulation bath Stretching, winding, and drying naturally to obtain seaweed fibers; 3) The degreased and washed cotton fibers are firstly subjected to puffing pretreatment, then carboxymethylation modification ...

Abstract

The invention discloses a method for preparing medical gauze with a bacteriostatic effect, and the method comprises the following steps 1) performing modification treatment on chitin fiber; 2) preparing alginate fibre; 3) preparing cotton fiber; 4) carrying out antibacterial treatment on the abovementioned obtained raw materials, and then preparing into a raw fabric of gauze; 5) immersing the rawfabric in a desizing-scouring-bleaching combined trough, first using water of 95 to 100 DEG C to wash, then lowering the temperature, performing water washing, adding finishing auxiliaries, and performing washing; and 6) then using clear water at the temperature of 105 to 110 DEG C to poach the abovementioned raw fabric, adding a hydrophilic softener and cellulase, discharging the fabric, and performing dehydration and drying. Gauze prepared by the method for preparing medical gauze has the effects of improving blood circulation, promoting metabolism, eliminating fatigue, inducing resuscitation and strengthening brain apart from traditional bactericidal and bacteriostatic and cleaning effects, a blood coagulation process can be accelerated and a layer of stable mesh-shaped gel is formed onthe surface of a wound, thereby creating a microenvironment conducive to tissue growth for the wound and promoting wound healing.
