example 1

[0026]Take by weighing 30g of silkworm chrysalis shells and put them into a beaker with 60mL mass fraction of 10% hydrochloric acid solution, mix and soak for 1 day at a temperature of 25°C, then add 90mL mass fraction of 30% sodium hydroxide solution into the beaker, Continue mixing and immersion at a temperature of 80°C for 1 hour to obtain the alkali-washed substance, and rinse the alkali-washed substance with 15% hydrogen peroxide for 3 times, control the pH value of the alkali-washed substance to 10, and remove the deacetylated carapace after washing Home-made chitosan; according to the mass ratio of 1:2:1, the home-made chitosan, glacial acetic acid solution with a mass fraction of 98% and polyvinyl alcohol were mixed and stirred for 45 minutes to obtain a modified home-made chitosan solution. The modified self-made chitosan solution is transported to the porous leaking plate, and the wire is drawn at a speed of 1500r / min to obtain the modified self-made chitosan fiber; t...

[0028] Take by weighing 35g silkworm chrysalis shells and put them into a beaker with 70mL mass fraction of 10% hydrochloric acid solution, mix and soak for 1 day at a temperature of 30°C, then add 100mL mass fraction of 30% sodium hydroxide solution to the beaker, Continue mixing and immersion at a temperature of 85°C for 1.5h to obtain the alkali-washed substance, and rinse the alkali-washed substance with 15% hydrogen peroxide for 4 times, control the pH value of the alkali-washed substance to 11, and remove the deacetylated substance after rinsing. Chitin is self-made chitosan; according to the mass ratio of 1:2:1, the self-made chitosan, glacial acetic acid solution with a mass fraction of 98% and polyvinyl alcohol were mixed and stirred for 50 minutes to obtain a modified self-made chitosan solution , the modified self-made chitosan solution is transported to the porous leaking plate, and the wire is drawn at a speed of 1700r / min to obtain the modified self-made chitosan ...

[0030] Take by weighing 40g silkworm chrysalis shells and put them into a beaker with 80mL mass fraction of 10% hydrochloric acid solution, mix and soak for 2 days at a temperature of 35°C, then add 110mL mass fraction of 30% sodium hydroxide solution to the beaker, Continue mixing and soaking at a temperature of 90°C for 2 hours to obtain the alkali-washed substance, and rinse the alkali-washed substance with 15% hydrogen peroxide for 5 times, control the pH value of the alkali-washed substance to 12, and remove the deacetylated carapace after washing Home-made chitosan; according to the mass ratio of 1:2:1, the home-made chitosan, glacial acetic acid solution with a mass fraction of 98% and polyvinyl alcohol were mixed and stirred for 60 minutes to obtain a modified home-made chitosan solution. The modified self-made chitosan solution was transported to the porous leaking plate, and the wire was drawn at a speed of 2000r / min to obtain the modified self-made chitosan fiber; th...

Abstract

The invention discloses a preparation method of a high-strength bacteria-inhibiting medical gauze, and belongs to the technical field of preparation of gauzes. The preparation method comprises the following steps of using modified chitosan fiber as a substrate, using cotton fiber as an additive, and using self-made antibacterial emulsion, modified nanometer titanium dioxide, dimethicone and the like as reinforcing agents, so as to prepare the high-strength bacteria-inhibiting medical gauze. The preparation method is characterized in that firstly, silkworm husk is subject to acid hydrolyzing and alkaline washing to prepare the self-made chitosan, so as to inhibit the growth and activity of multiple types of bacteria; then, nanometer zinc oxide, isothiazolinone and ibuprofen are mixed to prepare the self-made antibacterial emulsion; a grey cloth is soaked into the self-made antibacterial emulsion to form an antibacterial protection layer, thereby killing the bacteria. The preparation method has the advantages that the nanometer titanium dioxide with a certain strength is calcined and hydrolyzed by acid, and is mixed with a titanate coupling agent and stirred to form tough porous nanometer titanium dioxide, so as to directly attack the bacterial cells, and kill the bacteria; the antibacterial property of the medical gauze is further improved, and the application prospect is broad.

Description

technical field [0001] The invention discloses a preparation method of high-strength antibacterial medical gauze, which belongs to the technical field of gauze preparation. Background technique [0002] Gauze is a textile raw material, characterized by sparseness and obvious mesh; it is a kind of cotton fabric with sparse warp and weft. Gauze has a variety of varieties and is widely used; pure cotton gauze is mainly used for cotton quilts and silk quilt linings; degreased gauze is mainly used for medical bandages, medicinal cloths, adhesive plasters, etc. [0003] Gauze can be divided into pure cotton gauze, purified fiber gauze and blended gauze according to the different yarn raw materials. According to different weaving processes, it can be divided into single-layer gauze, double-layer gauze, and multi-layer gauze. According to different uses, it can be divided into civilian gauze, medical gauze, industrial gauze, etc. According to different colors, it can be divided i...
