Title:
AUTOMOBILE INTERIOR MATERIAL FOR FORMING AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH04194065
Kind Code:
A
Abstract:

PURPOSE: To obtain the subject interior material having light weight, small thermal deformation ratio and excellent formability by integrating a skin fiber layer and a substrate fiber layer by needle-punching, thereby forming a high- density region having a high apparent density and a reverse-side low-density region having low apparent density in the substrate fiber layer.

CONSTITUTION: A fiber web for skin fiber layer and a fiber web for substrate fiber layer are integrated by needle-punching from the side of the fiber web for skin fiber layer to give a gradient of the fiber density, decreasing from the fiber web for skin fiber layer to the fiber web for substrate fiber layer. A synthetic emulsion is impregnated into the fiber web for substrate fiber layer from the side of the fiber web for substrate fiber layer to obtain the objective forming interior material for automobile, composed of a skin fiber layer and a substrate fiber layer integrated with each other by needle-punching. The substrate fiber layer is composed of a high-density region having high apparent density and a low-density region having low apparent density and positioned at the reverse surface side of the interior material.
