Title:
SPUNLACED COMPOSITE NONWOVEN FABRIC
Document Type and Number:
Japanese Patent JP2014177719
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a spunlaced nonwoven fabric which has a stiffness and rigidity, while good touch and bulkiness of a spunlaced nonwoven fabric is held.SOLUTION: The spunlaced composite nonwoven fabric comprises a composite nonwoven fabric in which staple fiber webs are arranged in both surface layers and a filament nonwoven fabric is arranged between the staple fiber web layers. The filament constituting the filament nonwoven fabric has a cross-sectional shape in which substantial Y shapes are vertically and horizontally connected at the bottoms (hereinafter called as "substantial Y4 shape"), and has a single fiber fineness of 10 dtex or more. In the composite nonwoven fabric, constituent fibers in the staple fiber webs of both surfaces are integrally entangled with each other by hydro-entanglement, and staple fibers constituting the staple fiber webs of both surfaces are mutually entangled through apertures of the filament nonwoven fabric, and thus the staple fiber webs of both surface layers and the filament nonwoven fabric are integrated.
