Abstract

Disclosed is a method for producing an automobile sound absorbing member through molding. In the method, a first fibrous layer and a second fibrous layer are bonded to each other and molded at the same time, so that a working process and a process cycle are simplified, thereby improving production speed and reducing investment for equipment and facility. The method includes (a) preparing a first fibrous layer and a second fibrous layer, (b) providing an adhesive member between the first fibrous layer and the second fibrous layer and placing an aggregate of the first fibrous layer, adhesive member, and the second fibrous layer in a molding machine, and (c) pressing an upper mold and a lower mold of the molding machine so that the first fibrous layer and the second fibrous layer are bonded and molded into a molded body.
