Protective performance is the core function of Reusable medical protective clothing, which mainly includes the filtration efficiency of protective clothing against particulate matter in the air and the barrier properties of liquids such as blood, body fluids and other secretions.

Filtration efficiency refers to the percentage of particulate matter in the air (solid, liquid or solid and liquid mixed particulate matter suspended in the air, such as microorganisms, dust, smoke and mist, etc.) filtered out by Reusable medical protective clothing.

Anti-synthetic blood penetration refers to simulating blood to squeeze the Reusable medical protective clothing for a long time to check whether the blood penetrates and seeps out of the medical protective clothing.

Surface moisture resistance reflects the ability of water droplets to roll off the surface of Reusable medical protective clothing, and is evaluated by the level of wetness on the outer side of the protective clothing. The sample is sprayed with quantitative experimental water, and the appearance of the sample after the test is compared with the evaluation standard and the discriminator to determine its wet grade.
