Title:
TWO-LAYER TEXTILE FOR NONWOVEN FABRIC
Document Type and Number:
WIPO Patent Application WO/2017/187705
Kind Code:
A1
Abstract:
The purpose of the present invention is: to improve the dehydration properties and air permeability within a textile supporting a non-woven fabric while also maintaining a uniform surface density in the textile; to mitigate lodging of fibers that occurs during manufacture of the non-woven fabric; and to add the necessary properties of exceptional transverse rigidity, diagonal rigidity, and sheet support. The present invention achieves this purpose by providing a two-layer textile for a non-woven fabric comprising an obverse-surface layer that comprises obverse-surface-side warp yarns and obverse-surface-side weft yarns, and a reverse-surface layer that comprises reverse-surface-side warp yarns and reverse-surface-side weft yarns, wherein the two-layer textile for a non-woven fabric comprises a first warp yarn pair in which an obverse-surface-side joining warp yarn that functions as a joining yarn and a reverse-surface-side joining warp yarn that functions as a joining yarn are disposed in substantially perpendicular directions, a second warp yarn pair in which the obverse-surface-side warp yarn and the reverse-surface-side warp yarn are disposed so as to overlap in perpendicular directions, and a third warp yarn pair in which two obverse-surface-side warp yarns are apposed adjacent to each other.
