Since the outbreak of the new crown pneumonia, wearing masks has become a routine action in people's work and life. However, long-term wearing of masks will cause indentation, acne, allergies, chest tightness and other troubles. The reasons for these troubles are the breathability and moisture conductivity of the mask itself, poor antibacterial and bacteriostatic effect, and poor oxygen permeability. The inner layer of the chitin colloidal film non-woven mask fundamentally solves these problems and provides a guarantee for epidemic prevention work.

       The core of this innovative technology chitin colloidal film non-woven mask inner layer is the chitin bioimmune active substance that cannot be washed off with water. It has the characteristics of good film-forming oxygen permeability, antibacterial, oxygen enhancement, anti-corrosion, shielding and eliminating odor. , adsorption of heavy metals in human epidermis and other properties.

       The inner layer of the chitin colloidal film non-woven mask is attached to a certain amount of negative oxygen ions, thereby improving the internal environment of the oral cavity and the fabric, making breathing fresher and smoother, and solving the problem of hypoxia in non-woven masks to a certain extent.

       Medical workers wearing masks for a long time will cause adverse reactions to the facial skin to varying degrees. Because the inner layer of the chitin colloidal film non-woven mask contains the inherent biological immune active substances of chitin, it can prevent the human facial skin from being corroded by gastric acid and gas, and play a role in protecting the facial skin.
