Description
Technical Field
The utility model relates to the field of filtering devices, in particular to a seaweed fiber non-woven fabric.
Background
The respiratory infectious disease is spread through the droplets and the aerogel, has the characteristics of high spreading speed, wide susceptible population and high morbidity, poses great threats to public health and social stability, can block pathogenic microorganisms from invading human bodies by wearing the protective mask, and is an effective means for preventing the respiratory infectious disease and protecting the public health.
The biological protective mask is a mask for protecting the respiratory tract of a person in a biological pollution environment and can be divided into a passive biological protective mask and an active antibacterial biological protective mask according to the functions of the mask. The passive biological protective mask is a protective mask commonly used at present, and is mainly used for filtering out physical particles or harmful pathogenic bacteria in air in a physical filtering mode. The active antibacterial biological protective mask is characterized in that a certain antibacterial component is added into a mask material to endow the mask with an active antibacterial function. The filtering efficiency of the biological protective mask to particles can reach 95-99%, but pathogenic bacteria with infectivity adsorbed on the passive biological protective mask can be diffused again, and secondary pollution is caused to the environment and people. In order to prevent secondary infection caused by re-diffusion of pathogenic microorganisms attached to the mask, more and more attention is paid to mask materials with an active sterilization function and application thereof, and the mask materials can filter pathogenic bacteria and simultaneously play an active sterilization function. The addition of antibacterial agents to the filter materials is a simple and effective method for endowing the mask with an antibacterial function, and most of chemical antibacterial agents have toxic and side effects on human and the environment, so a new generation of masks with an active antibacterial function is yet to be further developed.
