Back in the Middle Ages, surgical procedures were unprotected and 80 percent of patients died during or after surgery. At the end of the 19th century, British doctors proposed to use carbolic acid to disinfect surgical instruments and operating room dressings, and encouraged doctors to wear disinfected clothes to perform operations to prevent the invasion of pathogenic bacteria. However, surgical clothes were not used at this time. In the 1940s, with the development of sterilization and infection control concepts, surgical gowns and surgical sheets became available. The original surgical clothes used loose structure, easy to permeate textile fabric material, can not fundamentally solve the problem of pathogen infiltration.
