Abstract

A leather-like fabric has a feel of natural nubuck leather and a napped feel and air permeability of suede leather, as well as high wear resistance. The leather-like fabric includes a fibrous structure including ultrafine fibers having an average monofilament fineness of 0.0001 dtex or more and 0.5 dtex or less, at least one surface of the fibrous structure being napped, the napped surface having resin layers located discontinuously, and each of the resin layers containing two or more layers.

First claim

The invention claimed is:

1. A leather-like fabric comprising a fibrous structure comprising ultrafine fibers having an average monofilament fineness of 0.0001 dtex or more and 0.5 dtex or less, at least one surface of the fibrous structure being napped, the napped surface having resin layers located discontinuously, and each of the resin layers containing two or more layers.

2. The leather-like fabric as claimed in claim 1 , wherein each resin layer has a three-layer structure containing an adhesive layer, an interlayer, and an outer layer.

3. The leather-like fabric as claimed in claim 1 , wherein each resin layer has a total thickness of 0.001 to 0.400 mm.

4. The leather-like fabric as claimed in claim 1 , having an air permeability of 1.0 cm 3 /cm 2 ·s or more as determined in fabric air permeability evaluation using the Frazier method specified in JIS L 1096 8.26.1.

5. The leather-like fabric as claimed in claim 1 , having a friction coefficient of 0.6 or less between fabric surfaces as determined in fabric friction coefficient evaluation performed by the KES-SE method.

6. The leather-like fabric as claimed in claim 1 , wherein the fibrous structure is artificial leather containing a polymeric elastomer inside the structure.

7. The leather-like fabric as claimed in claim 1 , wherein the fibrous structure is artificial leather containing reinforcing cloth formed mainly of a woven/knitted fabric inside the structure.

8. The leather-like fabric as claimed in claim 1 , having an elongation percentage of 15% or more and 35% or less in a warp direction and/or weft direction and an elongation recovery rate 70% or more and 100% or less in the warp direction and/or weft direction.

9. A leather-like fabric comprising a fibrous structure comprising ultrafine fibers having an average monofilament fineness of 0.0001 dtex or more and 0.5 dtex or less, at least one surface of the fibrous structure being napped, the napped surface having resin layers located discontinuously, and each of the resin layers containing two or more layers, wherein the leather-like fabric is rated as class 3 or higher in fabric wear resistance evaluation in terms of appearance deterioration after 1,000 abrasion cycles in Taber abrasion test specified in ASTM D3884.
