Document Type and Number:
WIPO Patent Application WO/2016/104412
Kind Code:
A1
Abstract:
To provide an elastic nonwoven fabric which, while having excellent elasticity, has regions of high contractile force and regions of low contractile force. [Solution] This elastic nonwoven fabric has a vertical direction and a lateral direction orthogonal to the vertical direction, contains elastic fibers and extensible fibers less elastic than the elastic fibers, and can stretch in the vertical direction, wherein, when the elastic nonwoven fabric has been stretched in the vertical direction, low-shrinkage regions which exert a contractile force in the vertical direction, and high-shrinkage regions which exert a contractile force greater than that in the low-shrinkage region are formed alternately along the vertical direction, and in the low-shrinkage regions, there are multiple cut ends formed by the elastic fibers being cut.
