った。The above-mentioned trim skin materials, high-frequency adhesive fabrics, and batted automobile carpets require special processing steps in order to maintain high-frequency weldability, which makes the work complicated and increases costs. In addition, with interior materials impregnated with a binder that has good high-frequency weldability, depending on the binder used, a so-called spark phenomenon may occur, in which carbonization occurs in a portion of the weld due to a discharge phenomenon during welding. There is a problem that the sealing part of the welder is damaged or the desired welder adhesive strength cannot be restored. All of these skin materials have a low peel strength after being subjected to high-frequency welding, so there is a practical problem in using them, for example, as skin materials for automobile interior materials.

を完成するに至った。[Problems to be Solved by the Invention] Therefore, in view of the problems of the conventional technology as described above, the present inventors have conducted extensive research to create a skin material for automobile interior materials that solves the problems. As a result, when a fiber layer made of a copolymer of vinyl chloride and vinyl acetate is provided on one surface of the fibrous base material, and at least the blade surface is impregnated with resin, a special processing step is required. High-frequency weldability can be easily obtained without the need for welding, and spark phenomena do not occur during welding, and the peel strength after welding is 6 kg/2.5 cm or more -1
The present inventors have discovered that a completely new skin material can be used that can completely eliminate these problems, and have completed the present invention.

適に使用しうる。As the fibrous base material used in the present invention, materials whose fibers themselves are flexible, such as nonwoven fabric, felt, fiber web, etc., are used. The thickness of these materials cannot be determined unconditionally because it varies depending on the strength and thickness of the target skin material and the type of material.
Usually 0.1~4, 0 mm <0.5~3.0
mm is used. Among the fibrous base materials,
A needle-punched nonwoven fabric whose thickness can be easily adjusted depending on the purpose and has excellent moldability and strength can be preferably used.

れているので好ましい。Examples of the fibers used for the fibrous base material include synthetic fibers such as polyester, polyamide, polyolefin, and acrylic; recycled fibers such as rayon; and natural fibers such as cotton and wool. In particular, polyester fibers are preferred because they have excellent light resistance and heat resistance.

る。The reason why fibers made of a copolymer of vinyl chloride and vinyl acetate are used for the fiber layer provided on one surface of the fibrous base material is that when such fibers are used, there is no spark phenomenon and high-frequency welding processability is achieved. This is because when the fibers are melted by welding, they are formed into a film while retaining the fibers in the fibrous base material, resulting in high adhesive strength. Furthermore, since the filmed part is very thin, it is easier to cut than the non-filmed part, and when trimming is performed after welding, for example, it is easier to work with and has an excellent finished appearance.

る。前記重量比は８５／ １５であるものが一般的に使
用されうる。The composition of the copolymer consisting of vinyl chloride and vinyl acetate constituting such fibers is a weight ratio (vinyl chloride/vinyl acetate) of 80/20 to 90/1 (l). If the ratio is less than 80/20, the fiber strength will be weak and it will be difficult to form a fiber web layer, and if it exceeds 90/10, the adhesive strength due to high frequency welding will decrease and sufficient peel strength will not be achieved. A weight ratio of 85/15 may generally be used.

A fiber layer may be laminated and integrated on the impregnated surface. The fibrous layer and the fibrous base material are integrated using bonding means such as needle punching, heat fusion, and adhesive.

車内装材として実用に耐えなくなる。Preferably, the resin is impregnated in a range of 20 to 80% of the thickness of the fibrous base material. If the thickness of the layer impregnated with the resin is less than 20% of the thickness of the fibrous base material, the properties as an automobile interior material, especially the surface abrasion resistance, will deteriorate, and if it exceeds 80%, it will deteriorate. The surface texture is hard, making it unsuitable for practical use as an automobile interior material.

It is preferable to adjust the impregnation so that the P/B ratio (hereinafter referred to as P/B) is 60/40 to 9515, where <80/20 to 90/0. If the P/B is less than 80/40, the resulting skin material will have a hard texture and poor moldability, and if it exceeds 9515, durability such as abrasion resistance and strength and elongation will be reduced. becomes.

In the method using a resin with welding properties in the comparative example, sufficient peel strength could not be obtained even if the amount of resin was increased, and the present invention obtained in Examples 1 and 2 was able to satisfy such strength. It can be seen that it is only the skin material. In addition, in all of the skin materials of the comparative examples, the seal part due to welding did not become film-like, and the cutability was poor.
The appearance of the interior materials provided was not good.
