Abstract

LA PRESENTE INVENTION CONCERNE UNE FEUILLE CONTINUE DE FIBRES NON TISSEES UTILISABLES COMME SUBSTRATS DE SEPARATEUR DE BATTERIE ALCALINE. LA FEUILLE A UNE FORCE DE 35GM ET UNE EPAISSEUR INFERIEURE A 200MICRONS. LE CONSTITUANT DE FIBRES PRINCIPAL EST UNE PATE SYNTHETIQUE CONSTITUEE DE FIBRES DE POLYOLEFINE THERMOPLASTIQUE AYANT UNE STRUCTURE MICROFIBRILLAIRE PREFONDUE SIMILAIRE A LA PATE DE BOIS. LE CONSTITUANT SECONDAIRE DE FIBRES EST UNE FIBRE DE POLYAMIDE DE TENACITE ELEVEE AYANT UNE LONGUEUR DE FIBRES SUPERIEURE A 6MM. L'AGGLOMERATION THERMIQUE PAR FUSION PARTIELLE DES POLYOLEFINES MICROFIBRILLAIRES EST SUFFISANTE POUR COMMUNIQUER A LA FEUILLE UNE RESISTANCE A LA TRACTION D'AU MOINS 157,5GCM ET TOUT EN CONSERVANT UNE PERMEABILITE A L'AIR DE 100LITRES PAR MINUTE ET DAVANTAGE. L'INVENTION EST UTILISABLE POUR LA FABRICATION DE BATTERIES ALCALINES.
