Patent ID: 7846282

Claim:
A method of manufacturing an automobile floor carpet, comprising the steps of: providing a thermoplastic resin containing at least one foaming ingredient selected from the group consisting of an inorganic foaming agent, an organic foaming agent and a thermal expansion microcapsule in an amount 0.5-5 mass parts with respect to 100 mass parts of the thermoplastic resin and containing a filler having a major axis particle diameter of 50 to 500 μm in an amount of 10-250 mass parts with respect to 100 mass parts of the thermoplastic resin; and pressing a nonwoven fabric, an adhesive film obtained immediately after extruding the thermoplastic resin having a melt flow rate of 10 to 1,000 g/10 min from an extruder, wherein the adhesive film is 50 to 500 g/m 2 in weight per unit area and has a foaming rate of 1.1 to 5 and a surface skin material piled together in this order with a pair of rollers, thereby obtaining an automobile floor carpet having an air-flow resistance of 1,245 to 12,450 N·s·m −3 .
