Title:
UNWOVEN FABRIC INCLUDING CELLULOSE FIBERS
Document Type and Number:
WIPO Patent Application WO/2022/225056
Kind Code:
A1
Abstract:
Provided is unwoven fabric having high handleability and adherability in a wet state. The unwoven fabric according to the present invention includes cellulose fibers, wherein a high fiber level region in which the amount of amassed fibers is large and a low fiber level region in which the amount of amassed fibers is low relative to the high fiber level region exhibit a herringbone pattern. The unwoven fabric is characterized in that: the friction coefficient of the front surface of the unwoven fabric is different from the friction coefficient of the back surface of the unwoven fabric in a dry state; and when the surface with a smaller friction coefficient is referred to as a front surface, and the surface with a larger friction coefficient is referred to as a back surface, the difference between the friction coefficients calculated by the following formula is 10%-80%: friction coefficient difference (%) = {(friction coefficient of back surface - friction coefficient of front surface)/friction coefficient of front surface} × 100.
