Barrier is the most important performance of disposable microporous protective coverall, including three aspects: liquid barrier performance, microbial barrier performance, and filtration performance.
Liquid barrier means that the medical microporous coveralls should be able to prevent the penetration of water, blood, alcohol and other liquids, and have a hydrophobicity of more than 4 levels to prevent the infection of the virus carried by the patient's blood, body fluids and other secretions from infecting medical staff. The microbial barrier refers to protective clothing against bacteria and viruses, and is mainly used to prevent contact transmission and cross-infection between medical staff and patients. Filtering performance refers to the prevention of the spread of viruses in the form of aerosols that are inhaled or attached to the skin surface, leading to infection.
