Title:
LEATHER LIKE SHEET SUBSTRATE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2004218164
Kind Code:
A
Abstract:

To provide a leather like sheet becoming soft at a part of getting a load such as bending or elongating and contracting for fitting to a foot in accordance with the movement of the foot, e.g., in the case of shoes, exhibiting a good wear feeling and keeping its shape in a part not getting the load, i.e., giving rise to a shape change similar to a natural leather.

This leather like sheet is constituted by a non woven fabric consisting of a conjugated type composite fibers in which ≥2 kinds of polymer components are arranged alternately by ≥5, and a polymer elastomer filled at the inside of the non-woven fabric, and when the leather like sheet is bent by 10,000 times according to JIS K6545 "the method for testing the bend resistance of a leather", it shows that a ratio of a fiber-splitting rate (x) at the bent part of the conjugated type composite fiber to the fiber-splitting rate (y) before the bending test is (x)/(y)≥1.5, and the fiber-splitting rate (y) before the bending test is ≤40 %.
