STRETCHABLE ARTIFICIAL LEATHER

摘要

PROBLEM TO BE SOLVED: To provide stretchable artificial leather that is excellent in mechanical strength and has a moderate elongation and a feeling of elongation stop in a longitudinal direction.SOLUTION: The stretchable artificial leather is composed of a fiber entangled body including ultrafine fibers having an average single fiber fineness of 0.9 dtex or less. The stretchable artificial leather has an apparent density of 0.40 g/cmor more and has an elongation coefficient of 50 or less calculated by the following formula (1): the elongation coefficient=5% circular modulus in longitudinal direction/thickness ...(1).
