る。In the above-mentioned ceiling material (1), a material bonded with a low-melting fiber web is used as the base material (2), so that the internal structure is not extremely densified, and a thick and cushioning base material is used. Since it becomes a material and the thickness can be reduced, it is possible to shape the surface into a ceiling shape and make the back surface into an arbitrary shape so as to be in close contact with the roof panel (7), and omit the wading material of the skin material Can be done. When a low-melting fiber mixed web is used for the skin material, the web is bound by the low-melting fiber, so there is no need for needle punching, and an interior material having a good appearance without needle marks on the surface is obtained. Can be Since the base material (2) made of the low melting point fiber web having such advantages has air permeability, the skin material (3)
If a material having air permeability is used, the ceiling material (1) itself becomes air permeable. In addition, the air-permeable ceiling material is very liable to be contaminated because the air containing the smoke and dust of the tobacco in the vehicle passes through. However, in the present invention, since the ceiling material (1) is made non-breathable by the hot melt film (4) which does not generate cracks or pinholes even when heated during the production or molding of the raw material (1A), the ceiling material is (1) Pollution due to air passage is prevented.
