Abstract

PURPOSE:To make a filiform pattern really appear on the surface of a product, and to improve high-class feeling and handmade feeling by transferring a reference line on a skin material from a molding die while sewing and working a filiform striped body intermittently exposed to a surface along the reference line. CONSTITUTION:In a skin material 13 for an interior part for an automobile with a core material 11 formed in a required shape and the skin material 13 covering the surface side of the core material 11 and being previously molded in the curved surface shape of a product, a reference line 14 formed in a recessed striped shape or a projecting striped shape is transferred from a molding die 20 at the time of molding while a filiform striped body intermittently exposed to a surface along the reference line 14 is sewn and worked. Accordingly, real feeling can be emphasized to a sewn section as the fine feel of a fine line can be expressed and a color can be contrasted, thus remarkably improving the appearance design properties of a product. The title interior part can simply be positioned to the mold rapidly on the basis of the reference line formed to the skin material, and positional displacement, etc., on molding are not generated by the fitting action of the reference line and the mold, thus enhancing workability.

<Means for Solving the Problems> In order to achieve the above object, the present invention includes a core material formed into a desired shape, and a core material formed in advance into the curved shape of the product, which covers the surface side of the core material. In an automobile interior part comprising a skin material, the skin material has a reference line in the form of concave or convex lines transferred from the molding die during molding, and the surface material is intermittently coated along the reference line. It is characterized by that the filament bodies exposed to the strands are sewn.
