PURPOSE: A manufacturing method of non-woven fabric mat for a car interior material is provided which has excellent sound absorption and sound insulation effect, maintains adiabatic effect, prevents wettability and high strength, minimizes the transformation of appearance after forming, has buffer effect, reduces production cost and environmental pollution. CONSTITUTION: The non-woven fabric mat is obtained by a process containing the steps of: mixing 10-20pts.wt. of polypropylene(PP) single fiber, 20-30pts.wt. of polyester(PET) single fiber and 30-50pts.wt. of low melting point polyester single fiber(L/M yarn) first; mixing 10-20pts.wt. of natural fiber comprised of flax and cotton with the mixture second to produce non-woven fabric; setting hot-melt having thermofusing binder function on the upper side of the non-woven fabric, and setting non-woven fabric confounded with a needle-punch on a lower side of the non-woven fabric; setting interior textile on the upper side of the hot-melt; passing through 200-250deg.C of hot blast and a roller press at 2-7m/sec of velocity; and then cooling to form.
