Definitions
- the present invention relates to a fiber composite material excellent in sound absorption suitable as a building interior material and an automobile interior material, and a method for producing the same.
- the adhesive resin layer to which the nonwoven fabric is bonded uses a thermoplastic resin having a melt flow rate of about! ⁇ 100 (gZlO), and this resin is continuously extruded from a heated T-die to the nonwoven fabric surface. It is formed by coating. Before the resin layer is cured, a cover material is pressed onto the resin layer to form an integral floor carpet.

- the force S required for a predetermined basis weight in order to obtain a uniform and sufficient adhesive action, and this predetermined basis weight and optimum air permeability are not always compatible.
- the air permeability of the carpet varies depending on the apparent density, thickness, and fineness of the nonwoven fabric, but the conventional adhesive resin layer itself has a very low air permeability.
- the adhesive resin is extruded from a T-die in a multi-row thread form and applied to the surface of the nonwoven fabric.
- the resin used is still less flexible in adjusting the air permeability. Since the amount is relatively large, there is a limit to weight reduction. In order to achieve both weight reduction and sound absorption, it is necessary to make it possible to freely adjust the air permeability with a small amount of resin, but the conventional adhesive resin layer has been unable to achieve this.
- the present invention has been devised to solve this problem, and its purpose is to enable a wide range of air permeability adjustment from a low air permeability to a high air permeability with a small basis weight of resin. It is providing the fiber composite material and its manufacturing method.
