Fiber properties and product characteristics






(1) fiber characteristics


· higher specific surface area, stronger adsorption and filtration performance;




· smooth fiber surface, no holes and other defects, with strong mechanical properties;




· non-toxic solvent residues, more suitable for use in the field of biomedical and tissue engineering, and more environmentally friendly during processing and use.






(2) product characteristics


· super filtration: the filter membrane has high porosity, the filter holes are nanoscale, and the filtration efficiency of PM0.1 particles is > 95%;




· super air permeability: the mask has more nanometer micropores, stronger air permeability, lower resistance and smooth breathing;




· strong safety: the core filter membrane of the mask is made of long fibers, avoiding the danger of fiber exudation into the user's lungs;




· reusable: the mask can be repeatedly washed, with the same filtration efficiency and longer application time after washing
