Problems solved by technology

At present, medical fabrics are based on cotton, which has the following disadvantages: 1. Not waterproof, not anti-fouling, easy to cross infection; 2. Poor air permeability, poor coloring performance, and insufficient comfort; During the process, there will be a lot of crumbs, which will easily cause uncleanness and infection; 4. It is easy to fold, and the fluidity of laundry detergent and disinfectant in wet fabrics is poor, which is easy to cause uneven disinfection, unclean cleaning, easy knotting, and not easy to clean. Dry
[0003] While the medical fabrics made of polymers have air permeability, the barrier rate is often not satisfactory. Therefore, it is necessary to research and develop a polymer medical fabric that is both breathable and high barrier rate.

Abstract

The invention discloses a high-barrier breathable medical fabric and a preparation process thereof, and relates to the technical field of medical fabrics. The preparation method comprises the following steps: polypropylene melt-blown cloth reacting with maleic anhydride under irradiation treatment to prepare modified polypropylene melt-blown cloth; then a polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer, tetraethoxysilane and 3-aminopropyltriethoxysilane reacting with hydrochloric acid, and adding the modified polypropylene melt-blown cloth during the reaction to prepare a blank material; and finally, mixing the blank material with 2-aminoterephthalic acid and an organic solvent, adding copper nitrate and 1-butyl-3-methylimidazolium chloride and mixing to prepare an electrolyte, electrolyzing electrolyte by taking a pretreated copper sheet as an electrode to prepare a pretreated blank material, and finally, carrying out hot pressing on the pretreated blank material to prepare the high-barrier breathable medical fabric. The high-barrier breathable medical fabric prepared by the invention has good barrier property and breathability.

Description

technical field [0001] The invention relates to the technical field of medical fabrics, in particular to a high-barrier breathable medical fabric and a preparation process thereof. Background technique [0002] The hospital is the main place for patients to undergo surgery, examination, treatment and rescue. The cleanliness of the hospital environment, especially the cleanliness and performance of medical fabrics, directly affects the patient's wound healing and health, and is also an important factor causing nosocomial infection and cross-infection. At present, medical fabrics are based on cotton, which has the following disadvantages: 1. Not waterproof, not anti-fouling, easy to cross infection; 2. Poor air permeability, poor coloring performance, and insufficient comfort; During the process, there will be a lot of crumbs, which will easily cause uncleanness and infection; 4. It is easy to fold, and the fluidity of laundry detergent and disinfectant in wet fabrics is poor,...
