関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a surface material for a surface of an interior part which is used for an interior part of a vehicle or the like and which is formed in accordance with an uneven shape of a ceiling, a door, a pillar or the like.

A method of applying and bonding to a substrate is considered, and stamping molding, vacuum molding, injection molding, and the like are used, but all require the elongation of the skin material.

り多く使用されてきた。[0004] Nonwoven fabrics for vehicles are made by laminating a certain thickness of a blended cotton obtained by cutting filament fibers of polyester, polypropylene or the like to a length of 50 to 80 mm, and needling with a number of needles to squeeze. Due to the advancement of needling technology, the design has also been improved, and since it is more productive and inexpensive than moquettes and tricots, it has been used more often as a skin material for automobile ceiling interior materials and trunk interior materials than before. .

【発明が解決しようとする課題】しかし従来の不織布の
破断時の伸び率は、１軸方向に対して最大でも８０％程
度であり、例えばドアトリムのアームレスト部のように
絞りが深く、局所的に１００〜１６０％も伸張されるよ
うな用途に対しては、成形時に破れが生じて実用化は困
難であった。However, the elongation at break of a conventional nonwoven fabric is at most about 80% in the uniaxial direction. For applications in which the film is stretched by as much as 100 to 160%, breakage occurs at the time of molding, and practical use has been difficult.

れていた。[0006] Further, since the nonwoven fabric is formed into a sheet shape by entanglement of the fibers by needling, the entanglement of the fibers is released by elongation, the fiber density decreases, and a so-called scale is generated. Therefore, for applications requiring a high degree of design, such as a pattern or color tone, such as a skin material, it is used at a maximum elongation of 60% or less, and the interior parts that can be used are limited.

The point is to provide a manufacturing method.

繊維をけん縮させる不織布表皮材の製造方法とした。In order to achieve the above-mentioned object, the present invention provides a non-woven fabric which is subjected to needling to form a pile on the surface, and heat-crimps the non-woven fabric as a surface layer as a back layer on the back surface. The heat-crimpable nonwoven fabric using fibers is overlapped, needling is performed from the heat-crimpable nonwoven fabric side of the same backing layer, the fibers of both layers are entangled with each other, and heated to crimp the heat-crimpable fiber. A method for producing a nonwoven fabric skin material was used.

Then, a difference in shrinkage occurs between the bonded fibers, and crimps are developed.

できる。The non-woven fabric using such heat crimped fibers is used as a backing layer and superposed on the surface non-woven fabric and needling is performed, whereby the heat crimped fibers are entangled with the fibers of the surface non-woven fabric, and heated in such a state to obtain heat crimp. When the fibers are crimped, the bonding is increased and the fibers shrink due to heat shrinkage, and a nonwoven fabric skin material having an excellent elongation is produced. Therefore, the nonwoven fabric skin material has a high fiber density, is excellent in designability, has high elongation at break, and can minimize the occurrence of invisibility.
