After the war, the water-repellent fabric was so marketable that it began to be used in surgical gowns. Since the 1980s, with the development of protection technology, new materials that can be used many times and are more durable have emerged, and the selection of materials for protective suit has been greatly expanded. Research on Medical Multifunctional protective suit. During medical treatment, when carrying out human body protection First of all, the virus or droplets should not be easily attached to the surface of protective clothing. Secondly, it should be able to prevent viruses from penetrating fabrics, and viruses contaminated on clothing and masks can be removed by washing, disinfection or sterilization. At the same time, the protective suit should also be able to maintain sufficient integrity and durability, tear resistance, puncture resistance, fiber strain resistance and wear resistance, no toxic components, no linting,Full Body Disposable Coverall, and good cost performance. Expand the full text According to the above requirements, antiviral protective suit should use high-performance isolation layer, combined with the corresponding functional finishing, and then use appropriate composite technology to achieve the functions of filtration and barrier, oil and water resistance, blood penetration resistance, anti-bacterial, anti-static, flame retardant, disinfection resistance, ventilation and comfort. Polyurethane film The PU membrane is a continuous non-porous micromembrane. Can be for by dry coating, wet coat, wet transfer coating, and hot melt polyurethane stretching on that fabric. Its waterproofness comes from the continuity of the film and the large film surface tension, while its moisture permeability is endowed by the molecular chains grafted or blocked with hydrophilic groups in the polymer molecules. Water molecules move outward along the dense molecular chain gaps and transfer outward through the adsorption and desorption of hydrophilic polymers. Because the waterproof performance of PU film depends on the thickness of the film, Medical Quickly Delivery Antivirus Coverall ,KN95 Face Mask with Five Layers, in order to achieve a higher waterproof or blood-proof ability, the thickness of the film must be increased, so that the moisture permeability is greatly reduced.Therefore, while ensuring the protective effect, efforts must be made to reduce the cost of protective suit. Environmental protection Finishing agents such as fluorochemicals used will affect the environment, so while paying attention to the functionality of protective suit, environmental issues should also be considered. Protective suit, as an important protective means for medical staff to prevent infection in the process of treating patients, needs further study by scientific researchers in the hope of developing a more perfect protective "armor".
