The sudden epidemic is changing people's consumption needs and lifestyle. With the rapid restart of the global economy and the continuous spread of the epidemic situation, many countries have begun to implement "mandatory mask orders." Although my country's epidemic prevention and control work has shifted from an emergency state to a normal state, health protection products such as masks and disinfection wipes have become the necessities of people's daily life. In the scorching summer, wearing a mask for a long time, the skin of the face is in a closed and humid environment, the stratum corneum of the skin is easily hydrated, and the resistance to irritants is reduced. Various bacteria will breed, dry itching, tingling, redness, acne, rash and other facial allergy problems may follow.

Traditional disposable masks generally have three layers: hydrophobic layer, filter layer and skin-friendly layer. It can only filter harmful bacteria and viruses in the air. Long-term use can easily cause bacteria and viruses to accumulate in the filter layer and masks become a "concentration camp" for bacteria. There are four layers of Hesu antibacterial masks, and one layer of Hesu antibacterial and antiviral non-woven fabrics based on "Hesu fiber". He Su fiber is a natural food-grade material. It is natural, non irritating, skin friendly, and has the effect of inhibiting Propionibacterium acnes (acne). It is not prone to allergies even if worn for a long time.

Grass fiber is a bio-based fiber with PLA/PHBV as the substrate. It is derived from plants and uses glucose made from corn starch as the main raw material to cultivate a large number of selected microorganisms, and then extract a polyester from the microorganisms. (Similar to mammalian fat)-PHBV, a new type of fiber produced by spinning process. It can be natural, no additives, green and environmentally friendly, long-term antibacterial and antiviral. Hesi fiber can destroy the cell wall of harmful bacteria and the cell membrane structure of viruses, causing bacteria and viruses to lose their activity and die, overturning the traditional way of relying on adding antibacterial agents to achieve antibacterial and antiviral effects for a long time.

The antibacterial indexes of the antibacterial and antiviral non-woven fabric of Hesu are: E. coli 99%; Staphylococcus aureus 99%; Candida albicans 99%, Klebsiella pneumoniae 99%, acne Propionibacterium 99.7%, methicillin-resistant Staphylococcus aureus 99% (test according to GB/T 20944.3-2008). The antiviral indicators of masks made of this material are: H1N1 influenza A 99.34%, H3N2 influenza A 99.26%, enterovirus (hand, foot and mouth virus) 91.91%, and polio virus 93.86%. Experiments have proved that Hesu non-woven fabric has broad-spectrum antibacterial properties against many types of bacteria and a high inactivation rate of main common viruses.

Experts speculate that the new coronavirus will coexist with humans for a long time. Wearing masks will become a long-term normative behavior. Even if the epidemic is completely over in the future, wearing masks in public places will surely become a long-term healthy habit of people.  The antibacterial and antiviral nonwovens and meltblown fabrics can be widely used in medical care, household textiles, baby products, sanitary products, medical materials, dressings and other fields to care for human health.
