Document Type and Number:
WIPO Patent Application WO/2016/051833
Kind Code:
A1
Abstract:
This laminated nonwoven fabric comprises a first fiber layer (10) and a second fiber layer (20) laminated thereon, and the first fiber layer (10) has multiple protruding sections (40) protruding from the second fiber layer (20) towards the first fiber layer (10). The protruding sections (40) are filled with the fiber that configures the first fiber layer (10). When the first fiber layer (10) is hypothetically divided in half in the thickness direction thereof and, of the two halved regions, the region farther from the second fiber layer (20) is called first fiber layer region number one (11) and the region closer to the second fiber layer (20) is called first fiber layer region number two (12), the hydrophilicities of the first fiber layer region number one (11) and the first fiber layer region number two (12) differ, and the hydrophilicity of the second fiber layer (20) is higher than the hydrophilicities of the first fiber layer region number one (11) and the first fiber layer region number two (12).
