NOVELTY - Medical antibacterial gauze, comprises 60-63 pts. wt. cotton fiber, 45-48 pts. wt. chitosan fiber, 35-38 pts. wt. bamboo fiber, 8-10 pts. wt. ceramic fiber, 1.1- 1.5 pts. wt. antibacterial agent, 1.5-3 pts. wt. graphene dispersion liquid and 3-5 pts. wt. finishing liquid. USE - Used as a medical antibacterial gauze. ADVANTAGE - The medical antibacterial gauze: is safe and non-toxic; has improved smoothness of the gauze surface, reduces the secretion of gauze and wound to generate adhesive, and reduces the pain of the patient. The porosity of the ceramic fiber is increased, so as to enhance the water absorption and ventilation property of medical gauze. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing medical antibacterial gauze, comprising (1) preparing antibacterial agent, (2) performing primary antibacterial treatment, (3) performing blending treatment, (4) performing secondary antibacterial treatment, crushing the antibacterial raw material, adding 450 -500 pts. wt. water to decoct, decocting to volume is one of the original one, filtering, adding the filter residue weight 45-50 times volume fraction of the filter residue is 70-75 % of alcohol solution, filtering, combining all the filtrate, and then evaporating to no alcohol state, then using AB-8 macroporous resin to purify, collecting the purified liquid, freezing and drying until there is no water, safe and non-toxic to obtain the antibacterial agent, where adding water into the antibacterial agent, stirring uniformly, the mass concentration of the antibacterial agent is 0.1-0.3 % to obtain the antibacterial liquid, immersing ceramic fiber in the antibacterial liquid, until completely absorbed, then freezing and drying until the water content is 0-3 % to obtain the antibacterial ceramic fiber, freezing and drying, the temperature is -35 -32℃, where in the step (3), the cotton fiber and antibacterial ceramic fiber are blended to obtain the central fiber, the bamboo fiber is blended with half of the central fiber, the bamboo fiber is wrapped with the central fiber to obtain the weft yarn, blending the bamboo fiber, the chitosan fiber and the central fiber, making the chitosan fiber wrap the thick central fiber to obtain the warp; weaving the warp yarn and weft yarn to obtain the medical antibacterial gauze for disposable antibacterial treatment, where in the step (4), arranging the medical antibacterial yarn in the finishing liquid for padding treatment, steam crosslinking, then water washing to obtain hydroxypropyl-β-cyclodextrin modified gauze, dipping the modified gauze in the oxide dispersion graphene, heating reaction, taking out and water washing to obtain the modified graphene, drying by cold air to obtain the medical antibacterial gauze for secondary antibacterial treatment. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the method of a medical antibacterial gauze. (Drawing includes non-English language text).
