NOVELTY - A textile article comprises a textile substrate having a bacterial filtration efficiency of less than 80% according to UNI EN 14683: 2019 Annex B, 0.5-20 g/m2 graphene with respect to the textile substrate, and which is dispersed in a polymeric binder, and forming an electric and thermal circuit heatable by Joule effect through the use of an external battery or by exposure to electromagnetic radiation in the infrared or microwave region. USE - Textile article used in filter for producing product for personal health protection e.g. personal health protection device and face mask (all claimed). Can also be used in air conditioning systems, exhaust hoods, industrial and domestic kitchens. ADVANTAGE - The filtering textile article has antibacterial characteristics and causes a limited pressure drop in an air flow that passes through it. It can be used in the production of a filtering manufactured product that can be sanitized once or several times after use. It has a high filtering power starting from a material with a much lower filtering power. It determines a pressure drop, expressed as respiratory resistance, of less than 60 Pa/cm2, measured according to UNI EN 14683:2019.
