Title (EN) COMPOSITE FABRIC FOR COVERSTOCK HAVING SEPARATE LIQUID PERVIOUS AND IMPERVIOUS REGIONS
(FR) TISSU COMPOSITE POUR COUVERTURE COMPORTANT DES ZONES SEPAREES PERMEABLES ET IMPERMEABLES AUX LIQUIDES
Abstract:
(EN) A composite nonwoven fabric is provided for use as a one-piece topsheet and barrier fabric for disposable absorbent articles including diapers, catamenial products, and adult incontinence products. The fabric is engineered to have a strikethrough region that is normally surfactant treated for receiving insults and transporting them to an absorbent core material for storage. The strikethrough region is bounded by liquid barrier regions that are suitable for defining containment structures, including diaper leg cuff. The barrier and strikethrough regions can be designed to have excellent low rewet characteristics and to have balanced properties comparable to or better than conventional spunbonded topsheet at comparable or lower basis weights.
(FR) L'invention concerne un tissu non tissé composite utile comme tissu barrière et de couche supérieure formé en une pièce pour articles absorbants jetables, tels que des couches de bébé, des produits pour menstruations et des produits d'incontinence pour adultes. Le tissu est conçu de façon à présenter une zone de pénétration traitée normalement avec des tensioactifs, qui sert à recevoir des salissures et à les transporter vers une matière centrale absorbante en vue de les stocker. La zone de pénétration est limitée par des zones barrières contre les liquides qui sont appropriées pour définir des structures de confinement, telles des couches à tour de jambe élastiques. Les zones barrières et de pénétration peuvent être conçues de manière à présenter d'excellentes caractéristiques de faible remouillage, ainsi que des propriétés équilibrées comparables à, ou meilleures que celles de couches supérieures filées-liées classiques pour des poids de base équivalents ou inférieurs.
