What are the good non woven fabric characteristics? Let's take medical grade non-woven fabric as an example. The excellent air permeability and filtration performance of medical grade non-woven fabric can ensure that the application in masks and protective clothing can effectively block bacteria and viruses; in addition, it is also required to have a soft feel and good water absorption to provide a comfortable use experience, while meeting environmental protection requirements, being able to be degraded or recycled, and reducing the impact on the environment.
