Abstract:
In a process of producing a stretch sheet, a strip-shaped laminate sheet 10A having an elastically stretchable elastic layer 1 and substantially inelastic, inelastic fiber layers 2 and 3 partially joined to each other at bonds 4 or a strip-shaped fibrous sheet containing an elastic component and a substantially inelastic component and having embossed regions formed by embossing in parts is stretched in directions starting from the bonds 4 or the embossed regions to obtain a stretch sheet 10. The stretch sheet has raised ridges and recessed grooves extending in the direction perpendicular to the stretch direction, and the bonds 4 or the embossed regions are present in the ridges.
