Title
(EN) FEMALE COMPONENT FOR REFASTENABLE FASTENING DEVICE HAVING REGIONS OF DIFFERENTIAL EXTENSIBILITY
(FR) COMPOSANT FEMELLE POUR DISPOSITIF D'ATTACHE UTILISABLE PLUSIEURS FOIS ET COMPORTANT DES ZONES D'EXTENSIBILITES DIFFERENTES
Abstract
(EN)
A female component for a refastenable fastening device having an elastomeric adhesive backing (34) and a multiplicity of fibrous elements (30) extending from the backing. The female fastening component is formed by a method comprising the steps of: providing a first lamina comprising an elastomeric, pressure-sensitive adhesive film having a first adhesive surface (31) and a second adhesive surface (33) opposed to said first adhesive surface, a relaxed orientation, an elongated orientation and preferably at least two regions of differential elongations; stretching said first lamina from said relaxed orientation to said elongated orientation; contacting a second lamina comprising a nonwoven web (30) with said first surface of said first lamina in said elongated orientation, thereby directly joining said second lamina and said first lamina to form a laminate; and relaxing said first lamina such that said second lamina is shirred to form catching regions capable of entangling the hooks (28) of a complementary male fastening component (20).
(FR)
Cette invention concerne un composant femelle pour un dispositif d'attache utilisable plusieurs fois, lequel composant possède un support adhésif élastomère (34) ainsi que plusieurs éléments fibreux (30) qui dépassent de ce support. Le procédé de fabrication de ce composant de fixation femelle comprend les étapes consistant à obtenir une première feuille se composant d'un film autocollant, lequel film possède une première surface adhésive (31), une seconde surface adhésive (33) opposée à la première, une orientation détendue, une orientation allongée, et de préférence, au moins deux zones d'élongation différentielle; à étirer la première feuille de manière à ce qu'elle passe de l'orientation détendue à l'orientation allongée; à mettre la première surface de la première feuille se trouvant en orientation allongée, en contact avec une seconde feuille se composant d'un voile non tissé (30), et joindre ainsi les première et seconde feuilles de manière à obtenir un stratifié; et enfin, à détendre la première feuille de manière à ce que la seconde se fronce et forme des zones d'attache capables de s'entremêler aux crochets (28) d'un composant d'attache mâle complémentaire (20).
