Title:
WATER-DISINTEGRABLE NONWOVEN FABRIC, WATER-DISINTEGRABLE WET NONWOVEN FABRIC, AND PRODUCTION METHOD FOR WATER-DISINTEGRABLE NONWOVEN FABRIC
Document Type and Number:
WIPO Patent Application WO/2019/150964
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a water-disintegrable nonwoven fabric having both excellent wet strength and water-disintegrability. The present invention pertains to a water-disintegrable nonwoven fabric in which pulp fibers and regenerated cellulose fibers are entangled. The regenerated cellulose fibers include flat rayon fibers. The water-disintegrability of a water-disintegrable wet nonwoven fabric, which is obtained by impregnating the water-disintegrable nonwoven fabric with pure water such that the mass ratio of the water-disintegrable nonwoven fabric in an absolute dry state to the water is 1:2, is 100 sec or less. The specific wet tensile strength of the water-disintegrable wet nonwoven fabric is 1.30 Nm/g or more.
