| Abstract: | The present invention relates to the design of a face mask that incorporates a waste derived warp knit polyethylene terephthalate (PET) permeate spacer layer for daily usage in current pandemic conditions. The central layer in the face masks is a selective hydrophobic layer that is recycled from waste RO membrane modules and is intended for usage as a non-medicated multi-layered face mask for common man. The mechanical strength and shape holding capability enables the preparation of the face mask in a unique 3D shape that extends from the nose bridge to the chin, leaving an air gap between the mouth and the inner layer of the face mask. Design advantage obtained by the incorporation of the PET layer enables smooth facial movements and hindrance free speaking. The 3D folding feature of the mask is seamless and fits snug on the user's face that which prevents spectacle fogging and chances of infections. |
