Respective samples of a non-woven polypropylene of a conventional type as used for surgical masks were coated with every of those options, the pattern was allowed to empty off extra liquid, and then allowed to air dry. This procedure using the above options resulted in a ca. 10% w/w deposition of the acidic polymer onto the substrate materials. A filter materials appropriate for use in the face mask based on any one of claims 1 to 26 comprising a fibrous substrate on which is deposited an acidic polymer together with an organic carboxylic acid.

The filter material of the invention in sheet kind may be adapted easily to the convex shape appropriate for fitting to a consumer’s face. The face masks may additionally comprise one or more layer of a further material, e.g. one layer backing the filter materials, or two layers sandwiching the filter materials, optionally with one or more additional layer. Such an extra layer of material may be situated within the face masks such that when the mask is used the layer of further materials is positioned between the filter materials and the consumer’s pores and skin to thereby reduce any irritation to the person’s skin. In one other way filter materials of the present invention may be made by recognized electrospinning processes, during which an electrified liquid jet of a polymer, in the form of a solution or soften is formed, and is deposited on a grounded collector fibre. For instance the filter material may incorporate one or more antimicrobial compound. Suitable examples of such compounds embrace quaternary ammonium compounds (e.g. benzalkonium chloride, cetrimide), phenolic compounds (e.g. triclosan, benzoic acid) biguanides (e.g. chlorhexidine, alexidine) and mixtures thereof.

Superior Viraloff® Antiviral Expertise

Influenza virus infection inhibitor and influenza virus an infection prevention product US B Sekisui Chemical Co., Ltd. A mask based on declare 2 wherein the air-permeable substrate contains a non- woven polyester. It is therefore seen that each one the polypropylene swatches upon which the listed acidic polymer had been deposited triggered 3 or greater than three Log reduction within the viral titer.

  • Much has been done to regulate and stop another pandemic from occurring with many anti-influenza products presently in the marketplace.
  • Such a filter may be of typically typical type, incorporating the filter material of the invention.
  • The anti-viral therapy is confirmed to successfully kill viruses by as much as ninety nine per cent over two hours – reducing the airborne unfold of particulates.
  • As per the report, the invisible coating on facemasks attacks the virus by rapturing its outer layer, effectively eliminating all new mutant variants, including the UK’s so-referred to as Kent variant and the South African variant.
  • Normally it’s utilized to fabric on the finishing stage of manufacturing.

7 A masks according to claim 6 wherein the acidic polymer contains a polymer of acrylic acid or methacrylic acid. A mask in accordance with any one of many previous claims wherein the acidic polymer contains a poly- polymer. The filter materials of this invention may be utilized in other types of breathing air filter such as nostril plugs. Such a filter may be of typically standard type, incorporating the filter materials of the invention. A face masks of this invention could comprise one, two, three or more layers of such a sheet or pad type filter materials.

For example a face mask of the invention could comprise a filter material comprising a polyester materials having an acidic polymer deposited thereon, and an extra layer of a non- woven polypropylene materials positioned to be between the filter material and the consumer’s skin. A layer of the filter material and a layer of the further materials could for instance be welded collectively, e.g. round their respective edges, e.g. by ultrasonic welding. A filter material in accordance with any certainly one of 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 material is in the vary g/m2. A face masks comprising a filter materials being a fibrous substrate, especially non-woven polypropylene or polyester, having an acidic polymer, especially of the Carbopol or Gantrez kind, deposited on the the fibres. The mask has an anti-viral exercise towards inhaled or exhaled air. A filter materials suitable for such a masks, and a course of for making it are additionally described.

Results confirmed that each one three loaded swatches killed the virus as follows, in which the Log Reduction Titer / ml is listed. A Log Reduction of 3 corresponds to a ninety nine.9% kill of virus. The loading options listed above were ready in one hundred sixty kg batches for software to a polypropylene or polyester non-woven cloth by spraying or dipping utilizing commonplace commercially available equipment, adopted by drying the wetted material in a drying tunnel. A discount within the viral titre of avian Influenza A NIBRG-14 H5N1 virus was observed after therapy with the test articles 2 (loading solution 1% ETD 2020 + 0.5% Citric acid), 3 (loading solution 2% ETD 2020), and four (loading resolution 2% ETD 2020 + 1% Citric acid). No viral discount was observed following treatment with test article 1 (loading solution 1% ETD 2020). 2) 200μl of diluted avian NIBRG-14 Influenza H5N1 virus at 1/10 (v/v) dilution in distilled water was added to every check or management article in a 6-well plate and incubated at Room temperature on a shaker (at 300MoT/minute) for 60 minutes.
