Composite stretchable member

摘要

Provided is a composite stretchable member with a smaller thickness and more uniform pleats. The composite stretchable member is stretchable in a first direction and is provided with a first nonwoven fabric sheet part and a second nonwoven fabric sheet part which are superposed on each other, and a plurality of elastic members which are arranged between the first nonwoven fabric sheet part and the second nonwoven fabric sheet part. The elastic members extend in the first direction while being separated from each other in a second direction perpendicular to the first direction, and the first nonwoven fabric sheet part and the second nonwoven fabric sheet part are joined with each other by an adhesive which is applied to the elastic members.

1. A composite stretchable member which is stretchable in a first direction, said composite stretchable member comprising:
a first nonwoven sheet part and a second nonwoven sheet part which are superposed over each other; and a plurality of elastic members which are arranged between the first nonwoven sheet part and the second nonwoven sheet part, wherein the elastic members extend in the first direction while being separated from each other in a second direction which is perpendicular to the first direction, the first nonwoven sheet part and the second nonwoven sheet part are joined with each other by an adhesive which is applied to the elastic members, a thickness of the composite stretchable member, when applying 3 gf/cm2 of pressure in a thickness direction of the composite stretchable member to the composite stretchable member in a 50% stretched state, is 2.0 mm or less, and a root mean square height of a profile curve of the composite stretchable member in the 50% stretched state is 0.4 mm or less.
