Definitions

  • side cuffs 24 and 24 made of a sheet material that is liquid-resistant or water-repellent and breathable are provided on both the left and right sides of the absorbent main body 2 along the longitudinal direction X. .
  • Each side cuff 24 stands up when the side cuff elastic member 25 arranged in an extended state along the free end contracts, and prevents the liquid from flowing out in the lateral direction Y.
  • the expanded and extended state means that the side seal portion is peeled off, the diaper is set in the expanded state, the elastic member of each part is expanded in the expanded diaper, and the design dimensions (the influence of the elastic member is eliminated at all). In this state, it is expanded until it becomes the same size as when expanded in a flat shape.
  • the state where the non-elastic fibers and the elastic filaments 33 are joined by dots or lines on their surfaces is not included in the burial according to the present invention.
  • the non-elastic fiber is preferably embedded in the elastic filament 33 with a degree of half or more of its diameter.
  • Each of the outer layer sheet 31 and the inner layer sheet 32 is preferably composed of two or more components of a low melting point component and a high melting point component.
  • the constituent fibers are bonded to each other at the fiber intersection by heat fusion of at least the low melting point component.
  • the core-sheath type composite fiber composed of two or more components of a low melting point component and a high melting point component those having a core of high melting point PET, PP and a sheath of low melting point PET, PP, PE are preferable.
  • the use of these composite fibers is preferable because the fusion with the elastic filament 33 becomes strong and peeling between the two hardly occurs.
  • olefin-based elastomers ethylene-based ⁇ -olefin elastomers, propylene-based elastomers copolymerized with ethylene, butene, octene, etc.
  • polyester-based elastomers polyurethane-based elastomers, and the like.
  • Two or more kinds can be used in combination.
  • core-sheath type or side-by-side type composite fibers made of these resins can also be used.
  • the melting temperature is preferably 130 to 220 ° C.
  • the softening temperature is measured as the temperature at the inflection point of the storage elastic modulus G ′ in the viscoelastic property of the measurement sample of the resin composition in sheet form.
  • the range from the softening temperature to the melting temperature is called a softened state.
  • the softening temperature is preferably 60 ° C. or higher, and more preferably 80 ° C. to 180 ° C., from the viewpoints of crystal growth of the resin composition during storage of the stretchable sheet 30 and a decrease in stretchability of the stretchable sheet 30 due to body temperature.
  • the elastic filaments 33 are joined with the sheets 31 and 32, the elastic filaments 33 are arranged in one direction without crossing each other. Then, in a state where the elastic filament 33 is joined with the sheets 31 and 32 and the elastic filament 33 is sandwiched between the sheets 31 and 32, these three members are clamped by a pair of nip rolls 63 and 63.
  • the condition of the clamping pressure affects the texture of the obtained stretchable sheet 30. If the clamping pressure is too large, the elastic filament 33 is likely to bite into both the sheets 31 and 32, and the texture of the stretchable sheet 30 obtained due to this tends to be lowered. From this point of view, the clamping pressure by the nip rolls 63 and 63 is sufficient so that the elastic filament 33 contacts both the sheets 31 and 32, and an excessively high clamping pressure is not required.

Abstract

Selon la présente invention, la constitution d'une couverture externe (3) comprend un stratifié d'une feuille étirable (30) contenant des fibres élastiques et des fibres non élastiques, et une feuille non étirable ne contenant pas de fibres élastiques. L'épaisseur d'une partie latérale scellée (4) est plus élevée par rapport à l'épaisseur de sections autres que la partie latérale scellée (4), dans une partie côté avant (F) et une partie côté arrière (R), respectivement, qui constituent la partie. Au niveau d'une surface d'extrémité extérieure (40) de la partie latérale scellée (4), il est formé une zone lisse (35) dans laquelle la surface d'extrémité extérieure (40) est lisse, des fibres élastiques étant présentes dans la zone lisse (35).
