高く軽量であり、断熱性、耐熱性などに優れる。(Prior Art) Conventionally, cardboard and various resin foams have been used for molded ceilings, which are one of the interior materials of automobiles. Cardboard is lightweight and inexpensive, but since the only means of shaping it is compression, it has poor formability and cannot be shaped into delicate shapes. Furthermore, it has the disadvantage of poor shape retention due to its hygroscopic properties. Therefore, resin foams are widely used. For example, JP-A-58-71154 and JP-B-Sho 58-2811 disclose molded ceilings using modified polystyrene foam. Such a molded body is IJ? Because it is obtained by foaming fat and molding it into a desired shape, it has excellent shaping properties, and the molded product obtained is relatively strong and lightweight, and has excellent heat insulation properties and heat resistance.

動車の走行燃費が落ちるという欠点もある。Moreover, since thermoplastic resin is used, the dimensional stability and strength at high temperatures are poor. Furthermore, since closed-cell foam is used to obtain a heat-insulating effect, sound is reflected on the surface, making it impossible to obtain a sufficient sound-absorbing effect. In order to improve the strength of such molded ceilings, reinforcing materials are laminated, and in order to obtain a sound absorption effect, sound absorbing materials are laminated or through holes are provided in the base material (Japanese Patent Laid-Open No. 55-1
No. 1947, Japanese Patent Application Laid-Open No. 53-14074, and Japanese Patent Publication No. 57-60944), the manufacturing process is complicated and costs are high. Another drawback is that the weight of the molded ceiling itself increases, reducing the fuel efficiency of the vehicle.

に通気性化粧面材を重ね合せて積層シートとする。In the present invention, a breathable decorative surface material is laminated on one side of the nonwoven fabric to form a laminated sheet, and the laminated sheet is heated to a temperature higher than the core point of the thermoplastic resin fibers contained in the non-woven cloth. After this heating or the nonwoven fabric is heated to a temperature higher than the melting point of the thermoplastic resin fibers contained therein, a breathable decorative facing material is laminated on one side of the nonwoven fabric to form a laminated sheet.

したり、あるいはその風合をそこねることがない。Next, this laminated sheet is press-molded with the breathable decorative facing material side facing upward. At this time, a part of the molten material formed when the thermoplastic resin fibers are heated to a temperature higher than their melting point acts as a pineapple for the inorganic fibers, adhering the inorganic fibers and converting the non-woven fabric into a base material. As the product is molded, the molten material from the spikes oozes out from the base material, and a portion of the molten material adheres to the base material and the breathable decorative surface material laminated on one side of the base material. During press molding, the air-permeable decorative surface material side faces upward, so the molten material released from the base material will not seep through the breathable decorative surface material and further upward, and will not stain the surface. , or without losing its texture.

成される。Furthermore, the remaining melt that has seeped into the base material forms a film that covers the side of the base material opposite to the laminated side of the breathable decorative surface material, that is, the lower surface during press molding. Forms a film in a shape. This coating becomes a layer that blocks air. Some sound-absorbing ceiling materials have air permeability, such as open-cell foam and glass cool, but this air permeability allows air to flow through the ceiling material, which prevents dirt from cigarettes, etc. Air passes through the ceiling and causes the ceiling to become dirty. For this purpose, a method of laminating an air-blocking layer, such as a plastic film, on the opposite side of the interior decorative material has been adopted, but this requires adhesive for lamination, which increases cost and weight. In this respect, the fibrous sheet manufactured according to the great invention has an air-blocking layer that is formed integrally with the inorganic fiber layer of the base material during press molding on the side opposite to the side on which the breathable decorative surface material is laminated. be done.

The compression force of press molding is usually 0.2 to 50 kq/cri, and the compression time is 10 to 600 seconds. In this way, a base material is formed by press molding in a range α05 to Q7 times the thickness of the original nonwoven fabric, and the thickness of the base material is 1 to 20 am.

If the nonwoven fabric used to form the base material contains inorganic fibers and thermoplastic resin fibers in a weight ratio of 10:1 to 1:5, the base material to be molded will contain a molten thermoplastic resin fiber between the inorganic fibers. It is glued together and is durable enough for practical use. If the content of inorganic fibers is higher than this ratio, the role of pineapple of the melted thermoplastic 111 fatty fibers will not be sufficient, and if the content of thermoplastic resin fibers is higher than this ratio, the strength will be lower. Although it is strong, the porosity decreases and the sound absorption effect deteriorates. ◎However, in the uninvented state, it is not enough for the molten thermoplastic resin fibers to bond between the inorganic fibers, and the molten material oozing from the base material It is necessary to bond between the base material and the breathable decorative facing material laminated on one side of the base material. Therefore, if the content of thermoplastic resin fibers in the nonwoven fabric forming the base material is less than 3:1 in the weight ratio of inorganic fibers and thermoplastic resin fibers, in addition to the nonwoven fabric, thermoplastic resin fibers The weight of nonwoven fabric with high resin fiber content is approximately one sister to the weight of the original nonwoven fabric.
The purpose can be achieved by using a laminated nonwoven fabric made by stacking boxes and simultaneously processing them with a needle punch or the like. In addition, the content of thermoplastic resin fiber in the non-woven fabric to be laminated is as follows:
It is preferable that the weight ratio of the inorganic fiber to the thermoplastic resin fiber is 3=11, preferably 1:1 or more.
