Abstract

PURPOSE:To eliminate the exfoliation of a thermoplastic film by laminating the thermoplastic film to the surface of a formed fibrous substrate at its softening temperature and heating the film to the melting point of the film thereby applying strong incorporation. CONSTITUTION:The fibrous substrate 1 is formed in advance into a prescribed shape and the thickness is reduced by a value corresponding to the mass of the film 2. The film 2 is laminated thereupon at a softening temperature. In this case, fibers are tangled with each other to cause the ruggedness on the surface. In heading the film 2 up to the melting point of the film 2, the film is molten and the ruggedness on the surface is lost by surface tension, the substrate 1 and the film 2 are coupled strongly and incorporated as a strong diaphragm 4. The surface is glittered and the value of the commodity is improved.
