| Title: | A Method for Preparation of Virucidal Polymer Textile materials and Virucidal Face Masks made from Said Materials |
| Description: | Methods for the treatment of textiles used for facial masks assure for the inactivation of viruses captured by the textile. The aerosol droplets are absorbed by the textile, and any viruses in the water droplets react with a virucidal substance. The surface of textile fibers is first exposed to gaseous plasma to assure appropriate wettability. The textile is then soaked in a diluted water solution of a virucidal substance. The excessive water solution is optionally removed by draining, and the drained textile is then dried. The methods enable uniform coating of the textile fibers with an extremely thin film of virucidal substance. A typical concentration of the virucidal substance in the textiles treated according to the methods of the aspects of disclosed embodiments is about 10 g/kg. Such a small concentration is benign to humans but effectively inactivates the viruses that might be captured by the textile. |
