A three dimensional shaped carpet used for an automobile comprising a surface material of the carpet and a formed body molded and connected in one with the surface material. A method of the present invention for manufacturing a three dimensional shaped carpet used for an automobile comprises steps of: coating a liquid foamable mixture directly on a back surface of the surface material by a spray system; placing the surface material in a molding die comprising an upper portion and a lower portion, the upper and lower portions defining a space inside the die corresponding to a three dimensional shape of the carpet; pressing and clumping the liquid foamable mixture with the surface material between those portions of the molding die, when the liquid foamable mixture coated on the back surface of the surface material has completed a gas reaction thereof but is still in a visco-elastic flowing condition; and changing the liquid foamable mixture into a solid condition, thereby a foamed body layer made of the liquid foamable mixture is molded in a three dimension and is molded and connected in one with the surface material through the back surface thereof. Droplets of the liquid foamable mixture sprayed on the surface material are entered into a fiber structure of the surface material and are attached on a surface of each fiber of the fiber structure while the liquid foamable mixture attached on each fiber of the fiber structure is immediately foamed and expanded by the gas reaction, so that the liquid foamable mixture is stayed at a shallow part inside of the surface material and is foamed without the liquid foamable mixture is impregnated into a deeper part thereof, and thereby the foamed body layer is in one with the carpet. <IMAGE> |
