摘要:
The present invention aims to provide an absorptive article improved so that, under a tensile force in a longitudinal direction so as to distance both ends from each other in the longitudinal direction, the article is sufficiently stretched. A sanitary napkin 10 as an example of pad-shaped absorbent article has a longitudinal direction A and a transverse direction B, opposite lateral ends 17 and opposite longitudinal sides 16 and includes a liquid-permeable topsheet 11 defining a skin-facing surface 11a, a backsheet 12 defining a garment-facing surface 12a and an absorbent body 13 between the top- and backsheets. The topsheet 11, the backsheet 12 and the absorbent body 13 respectively have an extensibility in the longitudinal direction A. The extensibility of at least one of the topsheet 11 and the backsheet 12 is an elastic extensibility. The sheets 11, 12 have first regions 29 extending across the absorbent body 13 in the transverse direction B to express an elastic extensibility and second regions 30 having an elastic extensibility in the longitudinal direction A lower than that of the first regions 29. The absorbent body 13 has a plurality of slits 33a, 33b extending in the transverse direction B and expresses an extensibility in the longitudinal direction A, when the article is subjected to tensile forces opposite in the longitudinal direction A so as to open the slits 33a, 33b and the absorbent body 13 is arranged so that at least one of the slits 33a, 33b overlaps with the first regions 29.

The present invention relates to a stretchable laminate. In particular, this invention relates to the use of the stretchable laminate in absorbent hygienic articles. Such hygienic articles have improved elasticity, fastening properties and better fit resulting in improved anti-leakage properties due to adjustable elastic properties of the stretchable laminate. Elasticity is adjusted by forming recesses of a definite distribution on a fabric layer without applying any elongation pre-forces to the layer and deforming it. Additionally, changing the distribution of the recessed parts provides variability of elasticity in a wide range for a wide range of materials which the fabric layer is produced from in a simple and economical manner. This way enables to obtain stretchable laminates of different elasticity by easily changing the distribution of the recessed parts without changing the dimensions and other basic physical characteristics of the fabric layer. Since the design parameters of the stretchable laminate are so diversified, preparation of the stretchable laminates ,which have varying elastic properties , by using fixed amount/size of the fabric layer is accomplished, whereby still shape, appearance and aesthetics of the laminate is maintained.

A disposable wearing article includes front and rear waist members respectively having a plurality of waist elastics extending in a transverse direction and spaced one from another in a longitudinal direction. The waist elastics are attached under tension and in a contractible manner to these front and rear waist members, and a crotch member joined to respective sides of the front and rear waist members. At least one of the front and rear waist members has two or more elastic zones defined in the longitudinal direction and differentiated in tensile stresses in the transverse direction and the first bonded region or regions is or are formed in the high elastic zone or zones included in the plurality of elastic zones and having the highest tensile stress.
