Abstract:
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.
