Problems solved by technology

[0003] Existing surgical caps will produce a lot of sweat due to long-term surgery during the doctor's use. The surgical cap will absorb sweat and breed bacteria. The growth of bacteria will reduce the surgical environment, cause wound infection of patients, and reduce the success rate of surgery.

Abstract

The invention discloses an operating cap material manufacturing process. The operating cap material manufacturing process comprises the steps of mixing butylene terephthalate, trifluoroacetic acid and dichloromethane to prepare a polyester solution, adding an antibacterial agent, carrying out ultrasonic treatment to prepare a spinning solution, and performing spinning to prepare an operating cap material. The antibacterial agent can destroy the phospholipid bilayers of bacterial cells, so that the cell membranes are damaged, and the protons, nucleic acids and proteins of the cells are oxidized; the cell membranes are destroyed to inhibit the growth and reproduction of bacteria; the antibacterial agent is quaternary ammonium salt; positive charge interacts with head groups of acidic phospholipids in the bacterial cell membranes, so that the infiltration capacity of the cell membranes is reduced, bacterial cell sap leaks, and the bacterial cells die; and meanwhile, the molecules of the antibacterial agent can enable bacterial protein to be denatured for preventing bacterial metabolism, so that the bacteria are killed, and a prepared operating cap is not prone to bacteria breeding.

Description

technical field [0001] The invention relates to the technical field of new material preparation, in particular to a manufacturing process of a surgical cap material. Background technique [0002] As a medical fabric, non-woven fabrics have developed rapidly in recent years, and non-woven fabrics are required in many occasions. The non-woven fabric composed of randomly arranged fibers, the size and shape of the holes distributed in it are conducive to the attachment of microorganisms, and become a good parasitic place for the survival and reproduction of microorganisms, and a transfer station for the re-spread of germs. Antibacterial fabrics endow the fabric with antibacterial properties, so that it can efficiently kill or inhibit bacteria, fungi and mold on the fabric, prevent bacteria from regenerating and multiplying, reduce the risk of re-transmission, and improve the safety of normal use and disposal of fabrics. [0003] Existing surgical caps will produce a lot of swea...
