Antimikrobielles textiles Glasfasermaterial

(A1) Beschrieben wird ein textiles Glasfasermaterial mit antimikrobieller Ausstattung sowie ein Verfahren zu dessen Herstellung.

DE 102007009619 A1 UPAB: 20081110 NOVELTY - The textile glass fiber material includes nanoparticulate silver. This is in the base coating, the adhesive layer and/or the antimicrobial coating. The fabric is woven, a fleece or a knit. The textile is made from E-glass and/or C-glass. Various layered fabric structures are described. The weight of the glass fiber material is 50-400 g/m2. The base coating is held on the glass fiber material using an aqueous binding system. No organic solvent is used. A wide range of common polymer and copolymer binders can be used. DETAILED DESCRIPTION - Optionally, additional materials are included, e.g. starch and its derivatives, wetting agent, thickener, pigment, filler, dispersant, de-foamer, stabilizer and processing aids. Natural or modified starch is used, suitable types and sources being nominated. One of a range of cellulose-based materials (listed) is used as a thickener. A cross-linking agent used, is based on zirconium, urea-formaldehyde or glyoxal derivatives. The dry weight of the base coating on the glass fiber material, is 10-200 g/m2. An aqueous dispersion adhesive is used, free of organic solvent. Further materials used, variants and sources are detailed. The mean size of silver nanoparticles is less than 500 nm. Their weight represents 0.1-50 ppm of the weight of the base coating, the adhesive coating and/or the antimicrobial coating, in which they are present. Quantified details are supplied, for use of additional silver oxide in these layers. AN INDEPENDENT CLAIM IS INCLUDED FOR the method of manufacture. USE - An antimicrobial textile glass fiber material. The material is used as a decorative or reinforcing glass fiber fabric, especially in living rooms, entries, staircases, corridors, sanitary zones, on external facades, in hospitals, medical practices, department stores, residential rooms, swimming baths, wet rooms, operation theaters, kindergarten and in tropical or subtropical climates (all claimed). ADVANTAGE - The material is ecologically-compatible and outstandingly antimicrobial. It is easily worked with, and preferably includes a water-activated adhesive. Its is placed in the baby-article Oko-Tex classification. Further detailed discussion is included.
