NON-WOVEN FABRIC FOR REINFORCING FOAM MOLDING ARTICLE

摘要

The present invention pertains to a non-woven fabric for reinforcing a foam molding article, the non-woven fabric being characterized in that a projecting fiber structure is formed by layering a short fiber non-woven fabric layer and a long fiber non-woven fabric layer partially formed with a minute crimped part, the short fiber non-woven fabric layer and the long fiber non-woven fabric layer being partially cross-entangled, and the fiber that forms the short fiber non-woven fabric layer passing through the long fiber non-woven fabric layer, and the stress at 5% elongation (ST5m) in the longitudinal direction is 10 to 30 N/5 cm, the stress at 5% elongation (ST5c) in the lateral direction is 5 to 25 N/5 cm, and the difference (DeltaST5m - ST30m) between the stress at 5% elongation (ST5m) in the longitudinal direction and the stress at 30% elongation (ST30m) in the longitudinal direction and the difference (DeltaST30m - ST40m) between the stress at 30% elongation (ST30m) in the longitudinal direction and the stress at 40% elongation (ST40m) in the longitudinal direction satisfy the following formulas. Formula (1): DeltaST5m - ST30m <= 25 (N/5 cm) Formula (2): DeltaST30m - ST40m <= 25 (N/5 cm)
