PURPOSE: A manufacturing method of a eco-friendly weed control mat is provided to endure wind, suppress the growth of weed by having improved absorption rate. CONSTITUTION: A lower layer(10) is made of a fire resistant processed polyethylene fiber. A surface layer(30) is combined to the top of the lower layer, and the exterior surface is smoothly heat-treated. A waterproof layer(50) is combined at lower part of a fragrant grass mat, to prevent water from entering to pavement through the surface layer, polyethylene fiber without fire resistant process is done. After lower layer, surface layer, and waterproof layer are punching processed through needle punching machine, inserted to heat roller and LM fiber is melted on roller and congeals to process surface smoothly. Eco-friendly weed control mat is produced in order as follows. The polyethylene fiber without fire resistant process is casted at fixed thickness. On the top of cast, UV processed polyethylene fiber and low melting point LM fiber mixture are covered for fixed thickness. On the top of cast, fire resistant processed polyethylene fiber is cased with fixed thickness. Three fiber layers are punched with needle punching machine and fiber textile is manufactured. Heat is applied to waterproof layer and exterior surface of surface layer to smoothly process the surface by passing fiber textile through heat roller and pressurizing.
