IMPROVEMENTS INTRODUCED IN THE PATENT OF INVENTION N. 200400749. BY 'MANUFACTURING AND FILTER PROCESS OF NON-WOVEN FABRIC AND / OR FILTERING INJECTED SHEETS OR STRUCTURES OBTAINED BY SUCH PROCESS FOR THE FILTRATION AND ELIMINATION OF THE LUMPION.

摘要

Improvements introduced in the invention patent No. 200400749 for "Manufacturing process and filter of nonwoven fabric and / or injected filtering sheets or structures obtained by said process for the filtration and elimination of legionella pneumofila". They consist of the incorporation in the extrusion of the fibers that are part of the filters of the main patent of other compounds such as antistatic, water-repellent, biodispersants, surfactants, flame retardants, as well as the treatment of plasma applied to non-woven fabrics from said fibers treated in extrusion, then it is possible to apply an impregnation treatment on the tissue by microcapsules without interference between compounds obtaining the following purposes: - Combination of the filters with other filter media that can be installed in said public, distribution networks of drinking water. - Manufacture of filters or filter structures in non-woven fabric from monofilaments. - Filters with antibacterial and anti-algae treatment, to avoid the formation of biofilm at the solid-liquid interface. - Improvement of the surface treatment of said fibers and monofilaments, giving them resistance to washing, incorporating biocidal substances into the structure of the fibers.
