An automotive floor carpet with improved sound absorption performance according to one aspect of the present invention comprises: a fabric unit; a sound insulation unit; and a sound absorption unit. The sound absorption unit includes: a garment scrap felt layer having surface density of 170-450 g/m^2; and a polyethylene terephthalate (PET) felt layer having surface density of 80-200 g/m^2. The automotive floor carpet according to the present invention is economical since the same uses inexpensive clothing scrap in comparison with conventional PET felt alone. Further, scrap fibers used in the sound absorption unit are not uniform in thickness and have various effects, thereby improving sound absorption performance.
