Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "left end," "right end," and the like as used herein are for descriptive purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In the development results of biotechnology nowadays, many medical researches find that some biomolecules, including lectin, Midin, polylysine, etc., have biological functions in vivo, can enhance the immunity of human body, and help the body capture, resist, and even kill foreign invaders. The extracted biological molecules can be combined with mask material to produce mask with biological protection function, which can adsorb and kill bacteria and virus in effective biological mode to make fine or nano level pathogen be easily captured.

Referring to fig. 1, an embodiment of the present invention provides a physical and biological dual protective mask, which is exemplified by an N95 mask, including: gauze mask body 10 and frenulum 20, gauze mask body 10 includes superficial layer 11, bilayer structure's filter layer 12 and close skin layer 13, bilayer structure's filter layer 12 sets up superficial layer 11 with between close skin layer 13, frenulum 20 is located gauze mask body 10 both sides for hang and lean on the ear.

The surface layer 11 is a hydrophobic sterile non-woven fabric which has waterproof and antibacterial functions and can isolate droplets in the air to prevent bacteria and viruses from spreading in a droplet manner, and meanwhile, particle pollutants with large volume, such as dust particles, can be filtered. Different patterns can be printed on the surface layer 11 according to the cloth characteristics of the surface layer 11, so that the integral aesthetic feeling of the mask is improved, and the requirements of individuation and fashion are met.

The filtering layer 12 with a double-layer structure comprises a physical filtering layer 121 and a biological protection layer 122, the physical filtering layer 121 is a melt-blown non-woven fabric with high-efficiency filtering, the melt-blown non-woven fabric has a high-density three-dimensional fiber mesh structure, and fine fibers can efficiently filter pollutants with relatively small particle sizes in air, such as pollen, suspended particles, bacteria, viruses and the like, according to a physical filtering principle.
