Problems solved by technology

This commonly used laminated filter material adopts a heat-bonded structure between layers, and the adhesion between layers is limited by the processing technology.
In addition, the current non-woven fabric material is mainly polypropylene single material, which cannot achieve extensive adsorption and filtration of micro-particles of various particle sizes

preparation example Construction

[0037] In a third aspect of the present invention, the preparation method of the above-mentioned laminated composite functional mask filter element is provided, comprising the steps of:

[0038] The antibacterial functional treatment is carried out on the activated carbon fiber layer to obtain the antibacterial filter layer;

[0039] Surface treatment of fiber monofilaments of spunbonded nonwoven fabrics to obtain a skin-friendly moisture-absorbing layer;

[0040] The protective layer, the antibacterial filter layer, the filter layer and the skin-friendly moisture-absorbing layer are superimposed in sequence, and then the carbon fiber is chopped and needled to form a whole.

[0041] In some embodiments, the method for carrying out antibacterial functionalization treatment to the activated carbon fiber layer comprises the following steps:

[0042] The activated carbon fiber layer is vacuum degassed at 120-140°C for 1-3 hours; vacuumize to extract the internal air.
