Document Type and Number:
WIPO Patent Application WO/2021/192985
Kind Code:
A1
Abstract:
The present invention provides: a nonwoven fabric; a method for producing this nonwoven fabric; a sheet impregnated with a liquid; and a wiping sheet. This nonwoven fabric (10) contains cellulose fibers (13), bonded sheath-core type composite fibers (11) and non-bonded sheath-core type composite fibers (14); the content of the bonded sheath-core type composite fibers relative to the total mass of the nonwoven fabric is from 5% by mass to 20% by mass; the content of the cellulose fibers relative to the total mass of the nonwoven fabric is not less than 45% by mass but less than 90% by mass; the bonded sheath-core type composite fibers have bonded parts at intersection points at which fibers intersect with each other and are bonded with each other; and the non-bonded sheath-core type composite fibers contain an ethylene-vinyl alcohol copolymer in sheath parts.
