Document Type and Number:
WIPO Patent Application WO/2020/071250
Kind Code:
A1
Abstract:
This wiping sheet (1) comprises a fiber aggregate (1A) including at least first fibers (11) and second fibers (12) that are finer than the first fibers, the fiber aggregate (1A) being obtained by entangling of these fibers, and the wiping sheet having a first surface (1F) and a second surface (1R) positioned on the opposite side from the first surface (1F). The proportion at which the second fibers (12) are present is higher in the first surface (1F) than in the second surface (1R). At least the first fibers (11) are irregularly shaped fibers in which a cross-section is non-circular. It is also suitable for a washing liquid to be supported by the fiber aggregate (1A). It is also suitable for the first fibers (11) to comprise a thermoplastic resin. It is also suitable for the tensile modulus of elasticity to be 1.3 × 10-3 N/mm2 or higher.
