Automatic Machine for N95-GRADE ANTI-VIRAL-BACTERIAL REFILL FILTER Production
ANTIVIRAL/BACTERIAL REFILL FILTER is one of the most important component in eGee-Pro® Reusable Mask. Constructed by 3 ply NON-WOVEN Materials each has its functional purpose:
OUTER BLUE PLY is meant for preventing external liquid such as water droplets, liquid or blood splash enter into center layer of the filter. It also blocks coarse particulates from passing through. It is is known as SPUN-BOND NON-WOVEN material. BLUE color is mainly used to indicate to user it is the outer layer.
CENTER WHITE PLY filter blocks any airborne microorganism such as virus, bacteria and fungi) passing through mask during inhaling. The QUALITY of this filtering material is mostly determined by this CENTRE PLY. It is known as MELT-BLOWN NON-WOVEN material composed with 0.1 - 0.3 micrometer mesh-like structure. Too thick causes higher breathing resistance while too thin run the risk of failing to serve its intended function to filter out all microorganisms.
INNER WHITE LAYER facing the internal mask cavity prevent droplets from mouth and nose to reach the center layer affecting the performance of center layer filter. It is is known as SPUN-BOND NON-WOVEN material.
The 3-PLY non-woven material are precisely arranged to be ULTRASONICALLY WELDED to form an integral in-line filter roll to ease user handling.
The roll of filters are further automatically measured and cut to precise length of individual filter.
