Beschreibung
Zusammenfassung:	A patterned nonwoven fabric comprising polymeric strands which include a primary polymeric component and are bonded together without the use of compression, but instead with a heat activated adhesive polymeric component which adheres the respective primary components together. The fabric has an embossed pattern of densified areas separated by high loft areas. Preferably, the strands are continuous, crimped, multicomponent filaments. Also preferably, the nonwoven fabric is laminated to a liquid barrier film to form an outercover material for products such as personal care absorbent articles, and the like. Methods for making these materials are also encompassed. Tissu non tissé à motif comprenant des torons polymères qui comportent un constituant polymère primaire et sont liés ensemble non pas par compression, mais à l'aide d'un composant polymère adhésif thermoactivé qui assure l'adhérence mutuelle des composants primaires respectifs. Ledit tissu possède un motif gaufré fait de zones densifiées séparées par des zones épaisses et aérées. De préférence, les torons sont des filaments continus, crêpus et à composants multiples. De préférence également, ledit tissu non tissé est appliqué sur un film imperméable aux liquides de manière à former un matériau servant de revêtement externe pour des produits tels que des articles absorbants d'hygiène personnelle et analogues. Des procédés de fabrication desdits matériaux sont en outre décrits.
