Moreover, the return rate of the test piece with respect to the amount of dropped oil is lower than that of Comparative Example 1 and Comparative Example 2. That is, Examples 1 to 7 indicate that the oil retention performance is high. In particular, Examples 1 to 7 show high oil retention performance as compared to Comparative Example 2 having the same nested type laminated structure (2 plies).
  • Example 1 see FIGS. 1 to 4) and Example 3 (see FIGS. 7 to 10), the position of the crepe paper on which the non-embossed portion is formed is upside down. Moreover, also in Example 5 (refer FIG. 13, FIG. 14) and Example 6 (refer FIG. 15, FIG. 16), the position of the crepe paper in which the non-embossed part was formed is an upside down position. . However, in Examples 1 and 3, and in Examples 5 and 6, high oil retention performance is maintained with respect to Comparative Example 2 (see FIGS. 24 to 27) of the same nested type. From this result, it can be seen that high oil retention performance can be exhibited regardless of the surface and back surface of the kitchen paper 100 that are in contact with the object of use.
  • the sheet has a pair of sheets, and the pair of sheets has a first sheet and a second sheet that face each other in a nested manner in which the embossed convex portions are formed.
  • the first sheet has an embossed part and a non-embossed part
  • the second sheet has an embossed part and does not have a non-embossed part. It was found that the absorption performance at the time was excellent.

Abstract

La présente invention concerne un papier hygiénique d'une seule pièce contenant au moins deux feuilles empilées. Le papier hygiénique contient deux feuilles, parmi lesquelles au moins deux feuilles adjacentes dans la direction d'empilement. Chacune des deux feuilles comporte, formées sur l'avant et sur l'arrière de celle-ci, une pluralité de sections convexes gaufrées et de sections évidées gaufrées en regard des sections convexes gaufrées. Les deux feuilles comportent une première feuille et une seconde feuille sur les surfaces desquelles les sections convexes gaufrées sont formées les unes en face des autres de manière imbriquée. La première feuille comprend une section gaufrée contenant une pluralité de sections convexes gaufrées et une pluralité de sections convexes non gaufrées, ainsi qu'une section non gaufrée ne contenant ni une pluralité de sections convexes gaufrées ni une pluralité de sections convexes non gaufrées. La seconde feuille comprend une section gaufrée contenant une pluralité de sections convexes gaufrées et une pluralité de sections convexes non gaufrées, mais ne comprend pas de section non gaufrée ne contenant ni une pluralité de sections convexes gaufrées ni une pluralité de sections convexes non gaufrées.
