Do Masks With Antiviral Coating Offer Extra Protection?
It is believed that the filter material of this invention may be effective on this manner against the virus that trigger colds, influenza, SARS, RSV, chook flu and mutated serotypes of these. A suitable materials for this additional materials is polyester, cellulose or non-woven polypropylene of the kind conventionally used for surgical masks and the like. A layer of the filter materials and a layer of the further material might for example be welded together, e.g. around their respective edges, e.g. by ultrasonic welding. A masks based on declare 23 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. A masks in accordance with any one of many preceding 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 within the range g/m2.
Water repellent technology– balances humidity and temperature ranges whilst repelling droplets containing viruses and micro organism. A mask according to declare 3 wherein the air-permeable substrate contains a non- woven polypropylene. A mask based on claim 1 whereby the air-permeable substrate comprises a fibrous substrate. Further experiments have been performed using a polyester substrate material.
Anti Viral Breathe Better Mask
Alternatively the substrate could also be in the type of an open-cell foam, e.g. a polyurethane foam as can also be used for air filters, for example in nasal air plugs. The filter material described herein may be made in various methods, by which the air- permeable substrate is combined with the acidic polymer. Other appropriate acidic polymers are believed to include polyvinyl phosphonic acids. Acidic polymers which have been found helpful for the purposes herein have been found to have molecular weights in the vary 30,000 to 2,000,000 however molecular weight doesn’t seem like important, and this can be simply an exemplary vary.
The filter 10 is of usually standard construction comprising a pad which can be attached over the nose and mouth of a user by a traditional strap . The pad includes an outer layer of the filter material of the invention stitched to an inner polyester fibre pad , the outer layer being in a position to intercept a stream of inhaled or exhaled respiratory air. Such a resulting liquid composition is herein termed a “loading solution”.
