Abstract:
The invention relates to a needle-punched nonwoven fabric wherein short fibers of polylactic acid containing an epoxy compound account for 20 to 40 mass % while short fibers of polyethylene terephthalate account for 80 to 60 mass %, the metsuke (weight per unit surface area) being 100 to 200 g/m2, and the tensile strength per metsuke at 20° C. being 0.30 to 0.60 (N/cm)/(g/m2) in the longitudinal direction and 0.48 to 0.90 (N/cm)/(g/m2) in the lateral direction. The present invention provides needle-punched nonwoven fabrics that are low in environment load, high enough in durability to serve as interior finishing material for automobiles, and high in stretchability during molding.
