Mesh materials for the controlled release of antimicrobial and antiviral compounds, with high antiviral activity and efficacy, predominantly against coronavirus, and a method for producing mesh materials with inclusion compounds of bisbiguanide:cyclodextrin, using mesh materials selected from polymers, fibers, nonwoven fabric, fabrics, paper and cellulose, individually or in combination, or a combination of one or more of these mesh materials with adhesives. The mesh materials impregnated, extruded, saturated, coated or laminated with inclusion compounds have been shown to be effective in the deactivation/destruction of viral particles. In fabrics, the inclusion compounds exhibited virucidal activity for all of the viruses in the coronavirus group for contact times of above 2 minutes, with the effect thereof lasting for more than 30 days. The mesh materials for controlled release of antivirals have displayed activity which is up to 1000 times more effective than the use of unencapsulated chlorhexidine.

A protective garment is constructed with a fibrous material. The fibrous material comprises a first nonwoven layer, a second nonwoven layer, and a nanofiber layer laminated between the first nonwoven layer and the second nonwoven layer. The fibrous material has a mean flow pore size greater than or equal to about 0.02 micron and less than or equal to about 0.5 microns, and a water vapor transmission rate greater than or equal to about 10000 g/m2/day and less than or equal to about 100000 g/m2/day. In a method of making a fibrous layer, a first nonwoven layer and a nanofiber layer are provided. A polyurethane reactive resin is applied to the first nonwoven layer in an amount of 2 to 30 g/m2. The nanofiber layer is then laminated to the first nonwoven layer applied with the polyurethane reactive resin and pressed to form the fibrous layer.

During national crisis as virus pandemics, bio-terrorism, chemical pollution, a response is to lock down all the economy, with several % GDP loss, or to convince population to wear, reasonably, appropriate individual anti-virus and bacterial protection accessories, made of a full head and shoulders protection mask, equipped with air ventilation and processing unit, and gloves, and body protection foil, for single or multiple use, and get minimal economic losses. The air processing unit may be developed a modular structure, starting from a simple filtered fan, with air suction on top of the head, flowing air over the face, for low probability of contamination environments, upgraded to a more complex unit including heat pipe, catalytic organic matter reduction, oxygen generator and closed circuit breathing unit, that may be integrated into a full body personal protection equipment by extending the functions of temperature, humidity and pressure control to full body, for hazardous environments.

The invention relates to a sterilizable and reusable ultraviolet-resistant elastomer composites including an elastomeric matrix comprising at least one elastomer; and an UV-resistant additive incorporated into the elastomeric matrix. The ultraviolet-resistant elastomer composite remains mechanically robust over at least 150 sterilization cycles, enabling safe reuse following ultraviolet germicidal irradiation (UVGI). Beyond N95 masks, these UVGI-compatible ultraviolet-resistant elastomer composites have potential utility in other PPE applications to address the broader issue of single-use waste.

 Appl.No 12554981 Applicant Inventor Plut William J.

Described herein is protective apparel that comprises a set of spacers attached to an undergarment. Each spacer attaches to the undergarment and is arranged under shroud material that rests over top of the undergarment. Collectively, the spacers maintain the shroud material proximate to each spacer distant from the undergarment worn by the person, thereby preventing continuous contact between the person and portions of the shroud material near the spacers. Multiple spacers form air channels between the spacers, the undergarment and inner portions of the shroud material. The channels permit low resistance airflow within the shroud material. Low resistance airflow within the channels permits air to be easily moved underneath the shroud material to cool the person.
