摘要： PROBLEM TO BE SOLVED: To provide a retractility composite sheet which is superior in the permeability of a thickness direction and/or a horizontal direction, keeps the appearance of a surface irregularity favorable, and is easily manufactured. SOLUTION: The retractility composite sheet includes a retractility sheet 10 and another sheet 2 which is laminated with the retractility sheet 10. The retractility sheet 10 includes a first domain 14 which has elastic retractility and a second domain 15 extensibility of which is inferior to that of the first domain 14, wherein the first and second domains 14, 15 are formed so as to respectively extend in one direction, and are interchangeably formed. Corresponding surfaces of the retractility sheet 10 and the another sheet 2 are joined by a large number of band-like joints 4 which extend in the cross direction which intersects the one direction and intermittent-arranged. The retractility composite sheet 1, as the composite sheet 1 whole, has at least retractility in the cross direction. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an absorbent article which forms beautiful pleats, looks like an underwear, and is excellent in air permeability and dehumidifiability. SOLUTION: The absorbent article 1 includes an absorbent body 3 and an exterior body 4, and has an abdomen side part A, a crotch part C, and a back side part B, wherein the abdomen side part A and the back side part B are joined to form a waist opening part 12, or the abdomen side part A and the back side part B may come into contact with each other to configure the waist opening part. The exterior body 4 includes an outer layer sheet 4A forming an outer surface of the absorbent article 1 and an inner layer sheet 4B layered on a skin-abutting surface side of the outer layer sheet. The exterior body 4 in a part 12' near the waist opening part has a plurality of pleats 41, 42 at intervals in the waist opening part periphery direction on the inner layer sheet surface and the outer layer sheet surface, and a pitch between pleats 42 and 42 on the inner layer sheet 4B surface is smaller than one between pleats 41 and 41 on the outer layer sheet 4A surface.

摘要： PROBLEM TO BE SOLVED: To provide an absorbent article having beautifully formed creases and an underwear-like outside appearance, and having excellent air permeability and dehumidifying capability. SOLUTION: The absorbent article 1 includes an absorbent body 3 and a shell 4. The shell has a stretchable composite part I including a stretchable sheet 38 and a non-stretchable sheet 36 joined to the stretchable sheet on the surfaces facing each other. In the stretchable composite part I in a natural state, a number of first projecting stripes 31 are formed on the surface on the non-stretchable sheet 36 side and a number of second projecting stripes 32 lower than the first projecting stripes 31 are formed on the surface on the stretchable sheet 38 side. The first projecting stripes 31 are disposed in an area abutting to the skin of a wearer on the surface facing the wearer's skin (on the inner side of the diaper) of the shell 4.
