ELASTIC WOVEN OR KNITTED FABRIC AND CUSHIONING MATERIAL EXCELLENT IN CUSHIONING PROPERTY AND RESISTANCE TO PERMANENT SET IN FATIGUE

摘要

PROBLEM TO BE SOLVED: To obtain an elastic woven or knitted fabric capable of exhibiting excellent elasticity and elastic recovery properties without causing slippage and suitable as a cushioning material.;SOLUTION: This elastic woven or knitted fabric having 150-600 N/5 cm stress at 10% elongation in at least either one of directions of warp and weft and ≤1% residual strain R after repeated deformation in the direction is obtained by heat-treating a woven or a knitted fabric comprising elastic yarns composed of two or more kinds of polyetherester-based elastomers different in melting point and arranged therein.;COPYRIGHT: (C)2001,JPO
