Title (EN) DISPOSABLE ABSORBENT ARTICLE INCLUDING AN ELASTICIZED AREA
(FR) ARTICLE ABSORBANT JETABLE CONTENANT UNE ZONE ELASTIQUE
Abstract:
(EN) Disclosed is a disposable absorbent article having a length and a width. The disposable absorbent article defines a first and second waist portion and a first and second longitudinal marginal portion. The disposable article includes the components of a backsheet layer, a topsheet layer, and an absorbent structure located between the topsheet layer and the backsheet layer. The article includes at least one elasticized area formed from an elastomeric, hot melt, pressure-sensitive adhesive, a first component and a second component, said first and second components being adhered to one another by said elastomeric, hot melt, pressure-sensitive adhesive. The elastomeric, hot melt, pressure-sensitive adhesive and the elasticized area formed therewith have the following characteristics: a) an adhesive bond strength sufficient to adhere said first and second components together during use of said disposable absorbent article; b) an elongation of at least 50 percent; c) a retractive force of less than 400 grams force per inch width at 90 percent elongation; d) a viscosity of less than 70,000 centipoise at 350 °F; and e) a cold flow value of less than 20 percent at 54 °C.
(FR) L'invention concerne un article absorbant jetable présentant une longueur et une largeur et présentant une première et une deuxième parties de taille et, en bordure, une première et une deuxième parties longitudinales. L'article jetable est composé d'une couche supérieure et d'une couche inférieure et, entre les deux, d'une structure absorbante. Il contient au moins une zone élastique formée d'un adhésif élastomère thermofusible autocollant, ainsi que d'un premier et d'un deuxième composants collés l'un à l'autre par ledit adhésif. L'adhésif élastomère thermofusible autocollant ainsi que la zone élastique ainsi formée présentent les caractéristiques ci-après: a) une adhésion suffisante pour fixer ensemble les premier et deuxième composants pendant utilisation dudit article absorbant jetable; b) un allongement d'au moins 50 %; c) une force de rétraction de moins de 400 grammes par pouce pour un allongement de 90 %; d) une viscosité inférieure à 70000 centipoises à 350 °F; et e) un taux de fluage à froid inférieur à 20 % à 54 °C.
