A disposable diaper having a tensile stress well compatible with a wearer's average body contour including convex and concave and thereby to reduce creating an uncomfortable feeling of tightness against the wearer. The disposable diaper including a front waist region that is divided into a first elastic zone extending in the transverse direction along a peripheral edge of the waist-opening, a second elastic zone lying next to the first elastic zone and extending in the transverse direction and a third elastic zone lying next to the second elastic zone extending in the transverse direction between the second elastic zone and the crotch region and the rear waist region is divided into a fourth elastic zone extending in the transverse direction along the peripheral edges of the waist-opening, a fifth elastic zone lying next to the fourth elastic zone and extending in the transverse direction and a sixth elastic zone lying next to the fifth elastic zone and extending in the transverse direction between the fifth elastic zone and the crotch region. The correlation among values of the tensile stress in the elastic zones can be represented by the sixth elastic zone>the second elastic zone>the third elastic zone≧the fifth elastic zone>the first elastic zone and the fourth elastic zone.

A composite sheet that has a low basis weight and can inhibit adhesives from flowing out is provided. The composite sheet 1 according to the present invention is formed by bonding a stretchable nonwoven fabric 2 and a non-stretchable nonwoven fabric 3 to each other with adhesives 4. The stretchable nonwoven fabric 2 in an extended state is bonded to the non-stretchable sheet. The stretchable nonwoven fabric 2 has a plurality of strip-shaped non-dense regions 21 and a plurality of strip-shaped dense regions 22 formed on both its surfaces alternately and alternately in the transverse direction such that the dense regions 22 on one of the surfaces and the dense regions 22 on the other surface are not overlapped with each other. The stretchable nonwoven fabric 2 includes thermoplastic fibers that have been stretched at least partially and elastomer fibers.

摘要:
A process for making an elastically stretchable composite sheet that includes an elastically stretchable web and inelastically stretchable web that are bonded together at a plurality of bonding spots. This stock web is stretched in a Y-direction and succeedingly contracted to obtain a composite sheet. The bonding spots are arranged so that each pair of the bonding spots lying adjacent to each other in a Y-direction at least partially overlap each other as one of these adjacent bonding spots is translated in the Y-direction.

摘要:
A method for producing a stretchable sheet that can uniform the shape, such as the width and thickness, and the strength, of a stretched nonwoven fabric. The method for producing a stretchable sheet according to the invention comprises a step of stretching a nonwoven fabric in the cross-machine direction perpendicular to the machine direction in which the nonwoven fabric is transported and a step of compressing the nonwoven fabric stretched in the step of stretching the nonwoven fabric, in the thickness direction of the nonwoven fabric.
