Abstract
(EN)
The present invention improves the feel of a composite sheet having folds. A composite sheet (70) is used for an absorbent article and comprises a stretchable member (73), a first sheet (71) which is disposed overlapping the stretchable member (73) and has a first welded portion (78) to which fiber is welded, and a second sheet (72) which is disposed between the first sheet and the stretchable member and has a second welded portion (79) to which fiber is welded. A plurality of the first welded portions and the second welded portions are disposed spaced apart in the stretch direction of the stretchable member. The pitch (P78) of the first welded portions in the stretch direction is different from the pitch (P79) of the second welded portions in the stretch direction.

La présente invention améliore le toucher d'une feuille composite ayant des plis. Une feuille composite (70) est utilisée pour un article absorbant et comprend un élément étirable (73), une première feuille (71) qui est disposée de manière à chevaucher l'élément étirable (73) et a une première partie soudée (78) à laquelle la fibre est soudée, et une seconde feuille (72) qui est disposée entre la première feuille et l'élément étirable et a une seconde partie soudée (79) à laquelle la fibre est soudée. Une pluralité des premières parties soudées et des secondes parties soudées sont disposées espacées dans la direction d'étirement de l'élément étirable. Le pas (P78) des premières parties soudées dans la direction d'étirement est différent du pas (P79) des secondes parties soudées dans la direction d'étirement.
