Anti Viral Face Masks
Such additional materials may be woven or non-woven material. Examples of non-woven supplies include polypropylene, polyethylene, polyester, nylon, PET and PLA. Such a fabric could also be within the form of a non-woven sheet or pad. Suitable grades of non-woven polypropylene embrace the well known grades commonly used for surgical face masks and the like.
As a number of treatments can be concurrently utilized, no extra water or vitality is required and the influence on the setting is lowered. The product is in the strategy of being licensed by bluesign and the Oeko-tex Eco Passports. Polygiene have examined the energetic ingredient against Influenza A, BirdFlu, Norovirus and Corona through the years, and in all instances, have achieved over ninety nine% discount within the virus. The effectiveness of the mask against the coronavirus and Influenza has been tested by an independent laboratory and a number one UK university.
Superior Viraloff® Antiviral Technology
A filter material in accordance with any considered one of claims wherein the entire loading of the acidic polymer plus any carboxylic acid if any and plus any surfactant if any on the substrate of the filter material is within the range g/m2. Respective samples of a non-woven polypropylene of a conventional kind as used for surgical masks had been coated with each of those solutions, the pattern was allowed to drain off extra liquid, and then allowed to air dry. This process using the above solutions resulted in a ca. 10% w/w deposition of the acidic polymer onto the substrate materials. WO-A-2001/07090 discloses a filter for eradicating micro-organisms comprising a substrate having a reactive floor and a polymer on its floor which includes cationic groups for attracting micro organisms. WO-A-2002/ discloses an air filter with micro-encapsulated biocides.
An instance of a metal salt of this kind is zinc chloride. As used herein the time period “acidic polymer” includes a polymer having acidic groups along its spine, e.g. as side groups. Suitable acidic teams are carboxylic acid groups. The acidic polymer could also be cross-linked or linear.
It is believed that the filter material of this invention could also be efficient in this manner in opposition to the virus that trigger colds, influenza, SARS, RSV, bird flu and mutated serotypes of these. A appropriate materials for this additional material is polyester, cellulose or non-woven polypropylene of the type conventionally used for surgical masks and the like. A layer of the filter material and a layer of the additional materials may for example be welded together, e.g. round their respective edges, e.g. by ultrasonic welding. A masks based on claim 23 wherein the total loading of the acidic polymer plus any carboxylic acid if any and plus any surfactant if any on the substrate of the filter materials is in the range g/m2. A masks according to any one of many previous claims whereby the whole loading of the acidic polymer plus any carboxylic acid if any and plus any surfactant if any on the substrate of the filter materials is in the vary g/m2.
- 7 A mask according to claim 6 whereby the acidic polymer includes a polymer of acrylic acid or methacrylic acid.
- Further experiments were performed utilizing a polyester substrate materials.
- The antiviral expertise is safety of the handled product, not the wearer.
- The face mask may also comprise a number of layer of an extra materials, e.g. one layer backing the filter materials, or two layers sandwiching the filter materials, optionally with one or more further layer.
This loaded material was moulded into masks shells in a traditional manner recognized within the art. Further experiments had been carried out using the “6% solids” loading answer referred to above, applied by spraying or immersion to lighter polyester supplies. Such filter materials might have unbiased utility, e.g. in other kinds of air filter system. Therefore in an additional aspect the present invention supplies a filter materials suitable to be used within the face masks of this invention. Preferred types, features and embodiments of such a filter material are as mentioned above. Certain filter materials disclosed herein to be used in the face mask of this invention are believed to be novel per se.
Disposable Anti Viral Face Masks For H1n1, Mrsa, Swine Flu, For Clinic
The filter 10 is of generally typical building comprising a pad which may be hooked up over the nostril and mouth of a user by a conventional strap . The pad comprises an outer layer of the filter material of the invention stitched to an internal polyester fibre pad , the outer layer being able to intercept a stream of inhaled or exhaled breathing air. Such a resulting liquid composition is herein termed a “loading answer”.
This invention relates to a novel system being an oral and/or nasal air filter capable of take away and neutralise dangerous virus from inhaled air contaminated with such virus, and from contaminated air exhaled from patients contaminated with such virus. In specific the invention pertains to such a tool in the form of a face mask. The invention also pertains to novel filter supplies appropriate for use in such a device. The antiviral expertise is protection of the treated product, not the wearer. Whether this is also helpful for the consumer is dependent upon many different factors.
The mask has been designed by Nottingham Trent University scientist and nanotechnology skilled,Dr Gareth Cave, and is now being commercialised by NTU spin out firm Pharm2Farm in Nottingham’s BioCity. The manufacturing course of for the brand new formulation, along with its antiviral, antibacterial and antiparasitic properties, had now been submitted as a patent software by P2F to protect its mental property. P2F had now overcome the delay in testing, reported on 8 October, by conducting reside virus exams at two independent UK laboratories. BioCity based Pharm2Farm have developed a coating for textiles which incorporates its proprietary nanoparticles, to offer textiles long-lasting virucidal properties.
