It is believed that the filter material of this invention could also be effective in this method against the virus that cause colds, influenza, SARS, RSV, bird flu and mutated serotypes of these. A appropriate materials for this further 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 may for instance be welded collectively, e.g. round their respective edges, e.g. by ultrasonic welding. A mask according to claim 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 according to any one of many previous 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.
Water repellent technology– balances humidity and temperature ranges while repelling droplets containing viruses and bacteria. A mask according to claim three wherein the air-permeable substrate comprises a non- woven polypropylene. A masks according to declare 1 wherein the air-permeable substrate contains a fibrous substrate. Further experiments have been performed using a polyester substrate materials.
Face Masks With Anti
Alternatively the substrate could also be within the form 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, in which the air- permeable substrate is mixed with the acidic polymer. Other appropriate acidic polymers are believed to incorporate polyvinyl phosphonic acids. Acidic polymers which have been discovered useful for the purposes herein have been discovered to have molecular weights within the range 30,000 to 2,000,000 but molecular weight doesn’t look like critical, and this may be simply an exemplary range.
Typically the filter materials may be in sheet or pad form, usually comparable to the shape of a starting sheet or pad of the fibrous substrate, suitable for use within the above- mentioned face mask. Such sheet or pad form supplies could be made into an acceptable form for a face masks of usually identified shape in a known manner. Face masks can be created from such supplies utilizing recognized masks-making processes, e.g. moulding / folding. Accordingly in a further side of this invention a process for making a face mask is supplied comprising providing a filter materials as described herein and forming the filter material into a face masks. One sort of such a filter includes a fibrous or particulate substrate on which is deposited, upon the floor and/or into the majority of such fibres or particles, a substance which captures and/or neutralises virus and/or different micro-organisms of concern.
Disposable Anti Viral Face Masks For H1n1, Mrsa, Swine Flu, For Clinic
Made from a gentle and cozy dark grey stretchy materials (82% polyester, 18% lycra), the material is breathable and light-weight for ease of wear. With stretchy ear loops and ergonomic form for a detailed match, this face masks conforms to ISO standards. We also provide an option to add a heat-sealed brand onto the face masks upon request, please contact us for further data. If you require face masks and coverings in numerous types in your staff, we additionally offer a number of other kinds of face coverings; including eco-friendly face masks and washable cotton face masks.
The coating transforms the bottom materials into an anti-viral, multi-functional protecting snood. So mild and breathable you will not consider its virus stopping power. Proven to lure and kill airborne enveloped influenza viruses. A filter material according to declare 28 whereby the acidic polymer is based on maleic acid moieties which include -[-CH.
