ABSTRACT:
Disclosed is a method of producing an automobile interior material or construction sheet with excellent processability, and its product made therefrom. More particularly, a method comprises by carding short fibers wherein short fibers are mixed with polypropylene fibers and polyethylene fibers in a mixing ratio of 3 to 7:7 to 3, on one side or both sides of a foamed layer produced by foaming any one selected from the group consisting of polypropylene chips, polyethylene chips, polyurethane chips, and expanded polystyrene chips; setting the short fibers with a shape of a truss in the foamed layer by interlacing the short fibers through a needle punching process; and thermally forming the short fiber layer(s) on the foamed layer by heating the portions of the short fibers exposed on the outside the foamed layer to 120 to 250° C. and pressing thereby melting, cooling and hardening the fused portions of the short fibers.
