Document Type and Number:
WIPO Patent Application WO/2019/130887
Kind Code:
A1
Abstract:
A fiber nonwoven sheet is provided which feels good against the skin and which, while having improved design properties, is not susceptible to tearing even when stretched in a first direction. A wipe sheet (10), which is a fiber nonwoven sheet, has a thickness direction (Z), a first direction (X) and a second direction (Y) perpendicular to the first direction (X), and a first surface (11) and a second surface (12) opposite to each other in the thickness direction (Z), and is formed by entangling constituent fibers. This fiber nonwoven sheet (10) has recessed lines (18) that are recessed in the first surface (11) towards the second surface (12) and are formed by fiber entanglement. The recessed lines (18) have second sections (82) extending in the first direction (X) and first sections (81) extending in the second direction (Y). The fibers in the second sections (82) are orientated in the second direction (Y). In the first sections (81), the number of fibers per unit area in the second direction (Y) is less than the number of fibers per unit area in the second direction (Y) in the second sections (82).
