The invention relates to a manufacturing process for an automobile carpet with high sound-absorbing performance. The manufacturing process comprises the following steps: conveying a surface blanket of the carpet to a baking oven for heating at 210 to 220 DEG C for 45 to 50 s, wherein the surface blanket of the carpet comprises a surface PET layer, a fibrofelt layer, a middle PET layer and a back PET layer which are compounded together from top to bottom; conveying the heated surface blanket of the carpet to a molding machine and carrying out compression molding on the surface blanket between an upper mold and a lower mold of the molding machine, wherein the temperatures of the upper mold and the lower mold are both controlled to be 10 to 13 DEG C, mold clamping pressure is controlled to be 0.7 to 0.8 Mpa, molding time is controlled to be 40 to 50 s, and a semi-finished carpet product is obtained after completion of molding; and putting the semi-finished carpet product in a cooling shaping tool for secondary shaping, wherein the cooling shaping tool employs a cooling shaping manner and is free of temperature control, cooling shaping lasts for 30 to 40 s, and a finished carpet product is obtained after completion of secondary shaping. The manufacturing process has the advantages of simple steps, easiness in operation and no production of harmful gas in the whole manufacturing process and is an environment-friendly manufacturing process.
