Nonwoven fabric having stretchability, and process for producing the same

摘要

The invention provides a stretchable nonwoven fabric which has concavo-convex structure on the surface, is bulky and highly flexible, has air permeability, and is capable of displaying stretchability in all directions irrespective of the directions of MD and CD. Specifically, the invention provides a stretchable nonwoven fabric, comprising a fiber layer (1) containing a heat-bondable fiber and a fiber layer (2) containing a conjugate fiber composed of resin components different from each other wherein the fiber layer (2) is laminated to at least one surface of the fiber layer (1), both fiber layers are integrated, the fibers of both fiber layers were no press-flattened at heat-bonded parts which is partly formed by heat-bonding of the heat-bondable fiber, and the fiber layer (1) forms a convex structure protruded to the fiber layer (1) side between the heat-bonded parts.
