Title:
BASE MATERIAL FOR ARTIFICIAL LEATHERS AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/134966
Kind Code:
A1
Abstract:
A base material for artificial leathers which comprises a nonwoven fabric made up of bundles of ultrathin fibers having an average filament fineness of 0.5 dtex or less and a high-molecular elastic body contained therein. This base material for artificial leathers satisfies the following requirements (1) and (2): (1) in an arbitrary section parallel to the thickness direction of the nonwoven fabric, there are 75 to 300 fiber bundles oriented in the thickness direction per cm of line segment orthogonal to the thickness direction; and (2) in an arbitrary section orthogonal to the thickness direction of the nonwoven fabric, there are 30 to 800 fiber bundle sections of fiber bundles oriented in the thickness direction per mm2. This base material for artificial leathers is suitably usable in producing an artificial skiver having both of a high softness with no repulsion and rich drape just like natural sheep skin and dense wrinkles formed by folding over and an artificial suede or nubuck leather having a fine surface texture and an elegant lighting effect that cannot be achieved by the existing products.
