CA 2435748

A fastening tape has a sheet-form base carrying an array of hooking members (10, 22, 24, 34) each having a height (h) of about 0.008 inch (0.2 millimeter) or less, as measured from the base, and fiber-engaging features, such as re- entrant tips (18, 32), disposed less than about 0.003 inch (0.08 millimeter) from their upper surfaces, as measured normal to the base. Such hooking members are employed to releasably engage directly into foams and fine denier non-woven materials, such as those of insulation, filters, construction moisture barriers, disposable gowns and diapers.

L'invention concerne une bande d'attache comprenant une base formée d'une feuille portant un ensemble d'éléments (10, 22, 24, 34) d'accrochage qui présentent chacun une hauteur (h) égale ou inférieure à environ 0,008 pouces (0,2 millimètre) mesurée à partir de la base, qui présentent des structures permettant la connexion avec les fibres, par exemple des pointes (18, 32) rentrantes, lesquelles sont placées à moins de 0,0003 pouce (0,08 millimètre) de leur surfaces supérieure, mesurée perpendiculairement à la base. Ces éléments d'accrochage permettent une connexion amovible par pénétration directe dans des mousses et des matériaux non tissés de fins deniers tels que ceux utilisés pour l'isolation, pour les filtres, pour les membranes étanches utilisées dans la construction, et pour les blouses et les couches jetables.
