Abstract

An object of the present invention is to provide a nonwoven fabric for molding with a good moldability, even when it is a binder-bonded and / or printed nonwoven fabric; and a surface material for automobile. In the nonwoven fabric for molding of the present invention, a binder for fiber bonding and / or a printing is applied to a fiber web, and a stress at 20% elongation in the cross direction of the nonwoven fabric for molding is 24 to 36 N / 3-cm-width. The surface material for automobile of the present invention consists of the nonwoven fabric for molding. In the present invention, it has been found that a good moldability is achieved when a stress at 20% elongation in the cross direction is 24 to 36 N / 3-cm-width.

Description

technical field [0001] The invention relates to a non-woven fabric for molding and a skin material for automobiles. In particular, the nonwoven fabric for molding of the present invention can be suitably used as a skin material for automotive interior materials such as ceiling materials, pillar materials, door trim materials, and rear package materials. Background technique [0002] Conventionally, as a skin material of an automobile interior material, a material subjected to a printing process for excellent decorative properties has been proposed. For example, the applicant of the present application has proposed: a decorative fiber sheet for automobiles that is printed in order to be able to feel a spacious interior space through printing, not to feel pressure, and to have color difference (Patent Document 1); Decorative fiber sheet for automobiles printed with difference in brightness (Patent Document 2); Decorative fiber sheet printed to change brightness (Patent Docume...
