Document Type and Number:
WIPO Patent Application WO/2023/084799
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide a multilayer nonwoven fabric which is readily smooth for a user and is not susceptible to twisting in cases where the multilayer nonwoven fabric is used as a wet wipe. A multilayer nonwoven fabric (1) for wet wipes, the multilayer nonwoven fabric (1) being provided with a first surface layer (3), an intermediate layer (5) and a second surface layer (7), while being characterized in that: each of the first surface layer (3) and the second surface layer (7) contains hydrophobic fibers and hydrophilic fibers, while containing no thermally fusible fibers; the intermediate layer (5) contains hydrophilic fibers (9) and not less than 5% by mass but less than 20% by mass of thermally fusible fibers (11); the thermally fusible fibers (11) in the intermediate layer (5) have portions that are bonded to each other; and the multilayer nonwoven fabric (1) has a wear volume of 21,000 µm2 or less in an abrasion test and a bending resistance of 25.0 mm or more as determined by a cantilever method.
