Abstract

The invention provides water-resistant medical cotton fabric resistant to protein contamination and a preparation method thereof. The method comprises the following steps: after the medical cotton fabric is activated by an alkali solution, fully immersing the medical cotton fabric in a triacetyl galloyl chloride solution, and adding a pyridine catalyst drop by drop, after constant temperature shaking, adding an acetate solution drop by drop, cooling and washing the materials, and drying the materials to obtain the antioxidant medical cotton fabric; dipping the antioxidant medical cotton fabricin a buffer solution of dopamine, and performing an oscillatory reaction at room temperature and taking the material out to obtain the polydopamine-modified medical cotton fabric; coating the surfaceof the polydopamine-modified medical cotton fabric with a polyethylene glycol solution, performing heat treatment in an oven at 75-80 DEG C for 60 to 120 min, cooling the material to room temperature, and then performing heat treatment with ethanol water vapor to obtain the medical cotton fabric. The surface of the medical cotton fabric prepared by the invention is not easy to form protein or a bacterial film, the medical cotton fabric has good anti-protein contamination performance, and is excellent in water resistance.

Description

technical field [0001] The invention belongs to the technical field of medical textile materials, in particular to a washable medical cotton fabric resistant to protein pollution and a preparation method thereof. Background technique [0002] During the diagnosis and treatment process of hospitals and other medical and health institutions, medical fabrics such as clothing, bed sheets, and surgical towels are reused. After contamination, there is a risk of spreading infection, and work procedures such as cleaning and disinfection must be carried out. In addition, if the medical textiles are easily contaminated by toxic substances discharged from the wound during use, it will affect the cleanliness of the wound, affect the recovery of the wound, and even cause deterioration. [0003] Chinese patent CN 104045846B discloses a dual-ion modified cellulose membrane and its preparation method. The dual-ion modified cellulose membrane undergoes hydrolysis and condensation between hyd...
