られている。(2) Prior art In recent years, the interiors of automobiles have become more sophisticated, and the use of fiber fabrics as interior materials has increased. Traditionally, interior materials for automobiles have many uneven parts, so polyethylene is extruded using a T-die as a backing material on the back side of the outer skin material such as pile fabrics such as tufted carpets, needle punch carpets, and moquettes, plain weave fabrics, and knit fabrics. Some products are crimped with a roll, then thermoformed, and then bonded with an adhesive or a fastener to a base material that has been previously formed into the required shape. In addition, other automotive interior materials include E, V, A (ethylene-vinyl acetate copolymer), S, B, R ( Styrene-butadiene copolymer), acrylic, and other resins as backing materials.
It is coated and adhered with an adhesive to a base material that has been preformed into the required shape or to a flat base material. In these cases, a material with sufficient strength, such as plywood, plastic plate, or iron plate, is used as a reinforcing base material.

業者への影ｇも無視てきなかった。(3) Problems to be Solved by the Invention However, among these methods, the former interior material is difficult to solve because differences in shape and dimensions occur between the carpet and the base material due to shrinkage of the thermoformed carpet. In addition, when attaching to a base material on-site, many problems occur because detailed gluing work is often required in invisible and difficult-to-reach areas. In addition, the latter interior material, like the former interior material, had poor adhesion workability, and because the carpet was not thermoformed, it could only be used on surfaces that were flat or had few irregularities. . In addition, both methods require a large amount of man-hours to attach the base material and the interior material, and in addition, the effects of the solvent on the adhesive on the worker cannot be ignored.

のでもよい。(4) Means for Solving the Problems The present invention solves the above-mentioned drawbacks of uneven interior materials for automobiles, and integrates decorative skin materials such as carpets and base materials, which was previously impossible. , the purpose is to enable direct installation by external setup without using any special base material inside the car body after thermoforming, reduce the number of decorative parts and the number of man-hours for installing parts, and reduce installation defects during installation. do. The present invention uses polypropylene 60~? '5wt% and glass fiber 3~15wt
% and other fillers from 0 to 30 wt%, and M and I are 10 to 30 g/10 min, extruded in a molten state, and then thermoformed into a laminate that is crimped onto the back side of a fiber fabric. . Suitable fiber fabrics in the present invention include fabrics such as tufted carpets, needle bunch carpets, moquettes, hand-woven fabrics, knit fabrics, etc. If necessary, CMC1 starch glue may be used to prevent tweezing and adjust stiffness.
It may be undercoated with latex, E, V, A, P, V, C, etc.

／ｍ以下では、厚さが不足し衝撃などに耐えられない。Further, in order to obtain sufficient physical properties using only the interior material of the present invention without using a special base material, the above-mentioned resin formulation is necessary. That is, if the polypropylene content is less than 60 wt%, the product becomes fragile and weak against impact, and since the resin content decreases, uneven blending tends to occur. Moreover, if it exceeds 75 wt%, the product becomes too soft. Further, when the glass fiber is 3 wt% ungrooved, its rigidity is low and it is easily deformed by heat. On the other hand, if it is added in excess of 15 wt%, it will become brittle and break easily, making it difficult to blend uniformly. Suitable inorganic fillers include those normally mixed into resins, such as calcium carbonate, magnesium carbonate, clay, talc, barium sulfate, asbestos, mica, and the like. Further, since mica is added as an inorganic filler to improve the strength of the resin in multiple directions, it is desirable to mix it in an amount of 3 to 7%. If the mixing ratio of the inorganic filler is 10 wt%, it will be too soft, and if it is 30 wt% or more, it will become brittle. Furthermore, if M and I are less than 10 g/10 min, the motor load on the T-die for coating becomes large, making extrusion difficult. Moreover, when M and I are 30 g/10 min or more, the fluidity is too good, making it difficult to make a film. It is more preferable that M and I are 15 to 20 g/10 min. In addition, since it is used without using a base material, the amount of resin applied to the fiber fabric is 1,200 to 2,500.
Preferably, it is g/d. Resin amount is 1.20.0g
