Surgical clothing mainly focuses on barrier (barrier) performance. Barrier properties include the ability to prevent penetration of liquids and microorganisms. Medical personnel in medical aid, will inevitably be exposed to the patient's blood and body fluids, blood and body fluids of patients are likely to carry HBV (hepatitis B virus), HCV (hepatitis C virus) and HIV (AIDS virus) and other pathogens. There are clothes worn in the use of surgery should be neat and clean, not easy to produce wool or dust, because of falling gown surface villi and particles to carry pathogens, causing harm to patient safety; at the same time, evaluate the protective performance of surgical clothing should be considered when the stretch fabric and wear resistance.

The barrier property mainly refers to the protective performance of surgical gown, the evaluation methods mainly include hydrostatic pressure, water test, impact penetration, spray, blood infiltration and microbial penetration and particle filtration efficiency etc.

Comfort properties include: breathability, water vapor permeability, drape, quality, surface thickness, static properties, color, reflectivity, odor and skin sensitization, and the impact of design and sewing in garment processing. The main indexes are permeability, moisture permeability, charge density and so on.
