Title:
LAYERED NONWOVEN FABRIC AND SANITARY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/153312
Kind Code:
A1
Abstract:
The present invention is a layered nonwoven fabric in which at least one each of a nonwoven fabric layer (A) composed of a first thermoplastic resin fiber and a nonwoven fabric layer (B) composed of a second thermoplastic resin fiber are layered, wherein: the cross-section of the first thermoplastic resin fiber has a plurality of lobes, and is a modified cross-section with a lobularity of 5% or more; the ratio (Db / Da) of the average single-fiber diameter Db of the second thermoplastic resin fiber to the average single-fiber diameter Da of the first thermoplastic resin fiber is 1.0 or more; and the nonwoven fabric layer (B) is layered on at least one of the outermost layers. This layered nonwoven fabric has water-absorption speed and water-absorbing/quick-drying properties sufficient to enable the fabric to be utilized as a sanitary nonwoven fabric. By employing this layered nonwoven fabric as at least a portion of a sanitary material, a sanitary material having excellent water absorbability and excellent quick-drying properties can be obtained.
