Face Masks With Anti
It is believed that the filter materials of this invention could also be efficient on this method against the virus that cause colds, influenza, SARS, RSV, fowl 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 materials and a layer of the further materials may for instance be welded collectively, e.g. round their respective edges, e.g. by ultrasonic welding. A mask according to claim 23 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 materials is in the range g/m2. A mask based on any one of the preceding claims 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 material is within the range g/m2.
Water repellent technology– balances humidity and temperature ranges whilst repelling droplets containing viruses and bacteria. A masks based on declare three wherein the air-permeable substrate includes a non- woven polypropylene. A masks according to claim 1 wherein the air-permeable substrate contains a fibrous substrate. Further experiments had been performed using a polyester substrate materials.
Face Masks With Anti
Alternatively the substrate may be in the type of an open-cell foam, e.g. a polyurethane foam as can be used for air filters, for example in nasal air plugs. The filter material described herein may be made in varied methods, during which the air- permeable substrate is mixed with the acidic polymer. Other suitable acidic polymers are believed to include polyvinyl phosphonic acids. Acidic polymers which have been discovered helpful for the purposes herein have been discovered to have molecular weights within the range 30,000 to 2,000,000 however molecular weight doesn’t look like important, and this may be merely an exemplary range.
The filter 10 is of typically typical development comprising a pad which may be hooked up over the nostril and mouth of a user by a conventional strap . The pad includes an outer layer of the filter materials of the invention stitched to an inner polyester fibre pad , the outer layer being able to intercept a stream of inhaled or exhaled respiration air. Such a ensuing liquid composition is herein termed a “loading answer”.
