ている。In automobile floor coverings, a cushioning material is used by being heat-welded or adhered to the back surface of the floor covering. A fiber felt is generally used as the cushion material. In addition, there are those made of urethane chips, polyurethane made by injection foaming, and the like, each of which is a separate component different from the upper layer and fixed to the back surface of the floor covering.

問題があるのでその解決おも目的とした。By the way, in the conventional floor covering, the peel strength of the plain carpet layer for the surface layer is weak, and therefore the abrasion strength is also weak, which is not practical. In addition, if a cushion material, which is a separate component, is fixed to the back surface, peeling often occurs. Therefore, an object of the present invention is to provide an automobile floor covering having a cushioning function which is free from such a problem and which does not cause the cushioning material to peel off. Separately, it was also aimed at improving the cuttability and the punching workability. In addition, the cushioning material, which is a separate component of the related art, is often a flat one, while on the floor surface of an automobile there is unevenness in the beads, so the adhesion of attachment is poor and the material deforms over time so that the surface becomes uneven. Since there is a problem that the external appearance quality deteriorates, we aimed to solve it.

It is possible to solve the intended improvement of surface wear strength and improvement of peeling strength of cushioning material by making it an automobile floor covering in which a fiber composite body formed by fusion of fibers is molded and processed. did it. Furthermore, the main purpose is to improve the surface abrasion strength and the peeling strength of the cushioning material, by saying, "The floor covering for automobiles is formed so that the back surface of the composite can be laid closely on the unevenness of the floor surface of the automobile." It was possible to improve the appearance quality and the mounting adhesion. Furthermore, “The side sills (1R, 1L), dash side edges (2), rear rear (3), notch (4), perforations and cross members (5R, 5L) of automobile floor coverings are thin. It was possible to improve the cutability and the punching workability, which are other purposes, by using the "automobile floor covering". Specifically, a molded article with good heat resistance could be obtained by using "a floor covering for an automobile in which the high melting point fiber is a polyester fiber and the low melting point fiber is a polypropylene fiber". Further, the cost can be reduced by using the "bedding material for automobiles in which the lower layer high melting point fiber and / or natural fiber is anti-wool". "The overall basis weight is 600-1
The weight of the lower layer is 500-1300 g / m 2 at 500 g / m 2.
It was possible to obtain a practical automobile floor covering by using "No. 2 automobile floor covering".

When it is 60% or more, the cushioning property of the lower cushion portion is deteriorated, which is not preferable. If the blending ratio of the low melting point fibers in the upper layer is 10% by weight or less, the surface abrasion strength is unacceptable. When it is 30% or more, the surface of the molded product is markedly shiny, which is not preferable in appearance.
