内装に用いられる改良された自動車内装材に関するもの
である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile interior material, and more particularly, to an improved automobile interior material used for interiors such as ceiling materials, door trims, rear packages, and trunk rooms of automobiles. is there.
従来、この種の自動車内装材としては、シボ付ポリ塩
化ビニールシートとポリウレタンスポンジとの積層材，
繊維編織布，或いはその起毛布等が使用されているが、
近年自動車内装の用途においては、軽量化，低価格化，
繊維化（高級化）指向が高まり不織布基材が多く用いら
れるようになってきた。Conventionally, as this kind of automobile interior materials, laminated materials of embossed PVC sheet and polyurethane sponge,
Fiber woven cloth or its raised cloth is used,
In recent years, in automotive interior applications, weight reduction, price reduction,
The tendency toward fiberization (upgrade) has increased, and nonwoven fabric base materials have been increasingly used.
特に、外観のおもしろさ、意匠性の向上を目的とし
て、２種以上の異なる色相を持つ繊維を混合し用いた、
いわゆる“霜降り”調の不織布が多く見かけられる。In particular, for the purpose of improving the interestingness of the appearance and the design, a mixture of two or more kinds of fibers having different hues was used.
There are many so-called "marbling" nonwoven fabrics.
しかるに上記の如く霜降り調の内装材を得る為に２種
以上の異なる色相を持つ繊維を混合する場合、混合比率
を一定にする為に、十分な注意を必要とし、作業性の低
下は免れない。However, when two or more kinds of fibers having different hues are mixed in order to obtain a marbling-like interior material as described above, sufficient care is required to keep the mixing ratio constant, and a decrease in workability is inevitable. .
また、予備開繊機の能力が不充分な場合には充分な混

装材としては不適当なものになる等の問題点がある。Also, if the capacity of the pre-spreader is insufficient, sufficient cotton mixing and blending will not be performed, and the formed nonwoven fabric will have large color unevenness in the width and length directions, making it unsuitable as an automobile interior material. There are problems such as becoming appropriate.
本発明は、上記課題を解決するため複数色のポリマー

することにより課題を解決したものである。The present invention solves the above problems by using a conjugate fiber composed of polymer components of a plurality of colors, and performing a needle punching treatment on a bulky fiber layer made of the fiber, thereby improving workability, and improving the width and width. An object of the present invention is to solve the problem by providing a uniform and excellently designed automotive interior material having no color unevenness in the length direction.
本発明の構成に使用されるコンジュゲート繊維として
はポリエステル，ナイロン，ポリプロピレン，ポリエチ
レン，アクリル，塩化ビニリデン等の溶融紡糸可能な並

グ法等により固定することができる。The conjugate fiber used in the constitution of the present invention is a parallel type, a radial type, a grain type, a mosaic type, an archipelago type single fiber such as polyester, nylon, polypropylene, polyethylene, acrylic, vinylidene chloride, etc. which can be melt-spun. Alternatively, a fiber layer is formed by using a plurality of these fibers in combination. After the needle punching treatment, the fiber layers are fixed to each other with a synthetic resin binder such as acrylate, SBR, NBR, polyester, polyurethane, etc. fixed by dipping, spraying, coating, etc. can do.
また、上記合成樹脂結合剤中へ難燃剤を添加し、難燃
性を向上せしめることも可能である。Further, a flame retardant can be added to the synthetic resin binder to improve the flame retardancy.
以下本発明を実施例に基づき詳細に説明する。 Hereinafter, the present invention will be described in detail based on examples.

Opening and laminating a bulky fiber layer using × 51mm, needle punching with a total of 300P / cm 2 from top and bottom
160 g / m 2 of automotive interior material was obtained.
尚、上記自動車内装材はコンジュゲート繊維に多層並

面状態の内装材を得ることができる。In addition, the above-mentioned automobile interior material can obtain a uniform and beautiful surface state interior material by using a fiber consisting of multiple colors divided into multilayer parallel type, radial type, grain shape, and mosaic shape for the conjugate fiber. Can be.
比較例 黒色に染色されたポリエステル繊維6d×51mm 50％と
白色のポリエステル繊維6d×51mm 50％とを用い、実施
例と同様にして自動車内装材を得た。Comparative Example A car interior material was obtained in the same manner as in the example, using 6d × 51 mm 50% of polyester fiber dyed black and 50% of white polyester fiber 6d × 51 mm 50%.
比較例では、２色の繊維の混率を一定にする為、正確
な秤量と調合が必要であるのに対し、本発明ではその必
要性がなくなり、作業性に大きな差が生じた。In the comparative example, accurate weighing and blending were necessary in order to keep the mixing ratio of the two-color fibers constant, but in the present invention, the necessity was eliminated, and a large difference in workability occurred.
また、本発明の自動車内装材は巾，長さ方向に対し、
全く均一な霜降り調内装材が得られたのに対し、比較例
では、長さ方向に濃淡の差が見られ、２色の繊維の配合
比率が常に１対１ではなく、ある一定の範囲内で変化し
ていることがわかった。In addition, the automobile interior material of the present invention has a width and a length,
While a completely uniform marbling-like interior material was obtained, in the comparative example, there was a difference in shading in the length direction, and the blending ratio of the two-color fibers was not always 1: 1 but within a certain range. It turned out that it was changing.
本発明は上記の如く、夫々色相の異なる複数のポリマ

質で高品質の自動車内装材となる等の効果を有するもの
である。As described above, the present invention greatly improves workability by using conjugate fibers composed of a plurality of polymer components having different hues, as compared with a case where a plurality of types of fibers having different hues are mixed and used. In addition to the fact that only one kind of fiber is used, the present invention has effects such as no unevenness of color and a homogeneous and high quality automobile interior material.
