The invention discloses an antibacterial automotive interior roof and a manufacturing method thereof. The antibacterial automotive interior roof comprises an upper surface layer and a lower surface layer, wherein the upper surface layer comprises an attaching layer and a first antibacterial and odor-resistant fabric layer; the lower surface layer comprises a second antibacterial and odor-resistantfabric layer and a non-woven fabric decoration layer; the attaching layer and the first antibacterial and odor-resistant fabric layer form the upper surface layer through hot pressing adhesion; the attaching layer and the second antibacterial and odor-resistant fabric layer form the lower surface layer through hot pressing adhesion; the upper surface layer and the lower surface layer form a roofsurface layer, and the roof surface layer is filled with a sound absorbing filling layer. With the adoption of antibacterial and odor-resistant fabric, the clearing and replacing cycle of the roof canbe effectively prolonged, and the use performance is better; the sound absorbing filling material can effectively reduce noise, and the comfort is higher; a formaldehyde adsorption layer can effectively absorb formaldehyde produced in an automobile, and harm to a human body is reduced.
