Abstract
(EN)
[Problem] To provide an absorbent article which improves the outward appearance of an absorbent article using a simple method. [Solution] A sheet member according to the present invention having a liquid-impermeable resin film 11 and a nonwoven fabric 12 adhered to one surface thereof, the sheet member being characterized in that: joined sections where the liquid-impermeable resin film 11 and the nonwoven fabric 12 are joined to one another via a microfibrous cellulose aggregate 15 and unjoined sections provided between the joined sections in a continuous or intermittent manner are arranged so as to repeatedly alternate with one another; and the nonwoven fabric bulges in the unjoined sections and does not bulge in the joined sections, resulting in the formation of unevenness in the nonwoven fabric 12.

Le problème décrit par la présente invention est de fournir un article absorbant qui améliore l'aspect extérieur d'un article absorbant à l'aide d'une méthode simple. A cet effet, l'invention concerne un élément en feuille ayant un film de résine imperméable aux liquides 11 et un tissu non tissé 12 adhérant à une surface de celui-ci, l'élément en feuille étant caractérisé en ce que : des sections jointes dans lesquelles le film de résine imperméable aux liquides 11 et le tissu non tissé 12 sont joints l'un à l'autre par l'intermédiaire d'un agrégat de cellulose microfibreuse 15 et des sections non jointes disposées entre les sections jointes de manière continue ou intermittente sont agencées de façon à s'alterner de façon répétée les unes avec les autres ; et le tissu non tissé gonfle dans les sections non jointes et ne gonfle pas dans les sections jointes, ce qui se traduit par la formation d'une irrégularité dans le tissu non tissé 12.
