イプの自動車内装用表皮材に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a skin material for automobile interiors. More specifically, the present invention relates to a flocked type automobile interior skin material that can be used for the interior of automobile ceilings and doors.
従来より植毛タイプの自動車内装用表皮材としては、（
（）ポリ塩化ビニルシートの表面に植毛加工を施したも

の植毛面の面積が１／２以下となるように収縮したもの
（特開昭８１−１７９３８２号公報参照）などが知られ
ている。Traditionally, flocked type car interior skin materials include (
() A polyvinyl chloride sheet whose surface has been flocked; (B) A nonwoven fabric containing heat-shrinkable fibers that has been flocked and then shrunk so that the area of the flocked surface is 1/2 or less (special (see Japanese Patent Publication No. 179382/1982) and the like are known.
前記（イ）の表皮材は、深絞り成形性がわるく、部分的
に表皮がのびて不均一な起毛面を形成することがあり、
またこの表皮単独ではクツション性や吸音性がないため

う欠点がある。また前記（ロ）の表皮材は、深絞り成形
性はよく、クツショク性にも優れたものであるが、不織
布は通常繊維が絡合した多孔構造を有するものであり、
その表面に凹凸があるので、植毛面の植毛長さが揃わず
地合のわるいものしかえられていない。The skin material of (a) has poor deep drawability, and the skin may stretch partially to form an uneven raised surface.
Furthermore, since this skin alone does not have cushioning or sound absorbing properties, it must be combined with other materials such as polyurethane foam, which has the disadvantage that the manufacturing process is complicated and costly. In addition, the skin material (b) has good deep drawability and excellent cushioning properties, but nonwoven fabrics usually have a porous structure in which fibers are entangled,
Because the surface is uneven, the flocked lengths on the flocked surface are not uniform, resulting in only poor texture.
そこで本発明者らは前記従来技術の問題点に鑑みて深絞

た。Therefore, in view of the problems of the prior art, the present inventors have conducted extensive research to create a skin material for automobile interiors that has good deep drawability, excellent cushioning properties, and has a uniform flocked surface. We have discovered a completely new skin material that can solve all of these problems, and have completed the present invention.

むニードルパンチフェルトの片面に植毛加工が施された
表皮材であって、該ニードルパンチフェルトの植毛が施
される面に平滑処理および撥水樹脂加工が施されている
ことを特徴とする自動車内装用表皮材に関する。That is, the present invention is a skin material in which one side of needle punch felt containing 15 to 40% by weight of heat-fusible fibers is flocked, and the surface of the needle punch felt on which the flock is to be smoothed and The present invention relates to a skin material for automobile interiors characterized by being treated with a water-repellent resin.
本発明の自動車内装用表皮材は、熱融着性繊維を１５〜
４０重量％含むニードルパンチフェルトの植毛される面
が熱カレンダーにより平滑処理が施され、この而にざら
に撥水樹脂加工が施された後に植毛加工が施されること
によりえられる。The automotive interior skin material of the present invention contains heat-fusible fibers ranging from 15 to 15%.
It is obtained by smoothing the flocked surface of needle punch felt containing 40% by weight using a thermal calendar, and then applying a rough water-repellent resin finish and then flocking.

繊維の移動を許し、また成形後、冷却されると再び結合
力が向上して保形性を付与するはたらきを有するので、
たとえば深絞りなどの成形が可能となる。The heat-fusible fibers used in the present invention include, for example, fibers with a melting point of 110 to 230°C, undrawn fibers, and fibers with a melting point of 110°C to 230°C.
Composite fibers containing components with a low melting point of 0 to 230°C are examples. Among these fibers, considering the fact that polyester fibers are usually used as fibers other than the heat-fusible fibers used in needle punch felting, a core made of polyester resin with a melting point of 130°C is used. ) and a sheath component made of a polyester resin with a melting point of 260° C. A core-sheath type composite fiber is desirable. Such heat-fusible fibers not only impart strength to the skin material by being fused, but also have the function of suppressing fuzz on the surface of the needle punch felt during calendering and improving surface smoothness. In addition, heat-fusible fibers weaken their bonding strength when heat is applied during molding.
It allows the movement of fibers, and when it is cooled after molding, it has the function of improving the bonding strength again and imparting shape retention.
For example, forming such as deep drawing becomes possible.
ところで、本発明において、ニードルパンチフェルトに
含まれる前記熱融着性繊維の使用量が１５〜４０重量％
とされるのは、１５ｆｆｌｆｆｉ％未満では必要な強度

こえると風合が硬くなるとともにクツション性が低下す
るためである。By the way, in the present invention, the amount of the heat-fusible fibers contained in the needle punch felt is 15 to 40% by weight.
This is because if it is less than 15% by weight, a skin material with the necessary strength cannot be obtained, and if it exceeds 40% by weight, the texture becomes hard and the cushioning properties decrease.

ニール以下であるのが好ましい。Examples of fibers other than the heat-fusible fibers include fibers commonly used for skin materials. Specific examples of such fibers include synthetic fibers such as polyester fibers, nylon fibers, vinyl chloride fibers, acrylic fibers, and polypropylene fibers, but these fibers may be used alone or in combination of two or more. You may. Further, among these fibers, polyester fibers are preferably used because they have little thermal deterioration or color change at high temperatures, and are excellent in heat resistance, weather resistance, and stain resistance. Further, the fineness of these fibers is preferably 6 deniers or less in order to hang a skin material having a uniform and smooth surface.

ｒｒｒをこえると、重量が重くなるうえに原料コストが

い。If the basis weight of the needle punch felt is less than 100 g/g, the cushioning properties will be insufficient, and if the weight is less than 400 g/g
If it exceeds rrr, the weight becomes heavy and the raw material cost tends to increase, so it is usually 100 to 400 g/go,
It is preferable to adjust the amount to <150 to 350 g/a.

られる。The surface of the needle punch felt on which flocking is to be performed is smoothed using a thermal calendar. Examples of such thermal calenders include flat calenders with a temperature of 120 to 200°C. By performing such a smoothing treatment, the fuzz that protrudes from the needle punch felt is suppressed, and the surface of the needle punch felt is smoothed.
つぎに平滑処理が施されたニードルパンチフェルト表面

をこえると接着剤自体の接着力を低下させる傾向にある
。Next, a water-repellent resin is applied to the smoothed surface of the needle-punch felt to prevent the flocking adhesive from penetrating into the needle-punch felt. Such water-repellent resins include, for example, fluorine-based water-repellent resins such as perfluoroalkyl group-containing acrylates and perfluoroalkyl group-containing urethane compounds, and the adhesion amount is usually adjusted to 5 to 30/rrr. Ru. If the amount of adhesion is less than 5 g/n-4", the water repellency will decrease and the adhesive for flocking will penetrate into the felt, reducing the adhesive strength of flocking.
Exceeding this tends to reduce the adhesive strength of the adhesive itself.

ｒｒｆ、なかんづ＜５０〜１２０ｇ／ばであるのが好ま
しい。Examples of such adhesives include acrylic resin emulsions and ethylene-vinyl acetate resin emulsions. The viscosity of such a resin emulsion is 1000
If it is less than 0 cP, the adhesive strength of flocked hair may decrease due to the resin penetrating into the needle punch felt, and if it exceeds 40,000 cP, it becomes difficult for flocked fibers to stick and the adhesive strength of flocked hair decreases. Therefore, it is preferable that it is in the range of 10,000 to 4,000 (]cP.The amount of adhesive for flocking (resin solid content) varies greatly depending on the fineness and fiber length of the flocked fibers. For example, when flocking short nylon fibers with a fineness of 2 denier and a fiber length of 1.2 am, if the amount of adhesive attached is less than 40 g/I, a sufficient amount of short fibers will not be stuck, resulting in a low flocking density. You will only be able to get a flocked surface that lacks uniformity, and if it exceeds 150g/r+f,
Since adhesive tends to be excessive, 40 to 150 g/
It is preferable that rrf is <50 to 120 g/ba.

しい。Fibers are flocked on the surface to which the flocking resin is applied. As a means for such flocking, for example, a commonly used electrostatic flocking method can be employed. Fibers used for flocking include, for example, rayon fiber,
Examples include nylon fiber and polyester fiber. The fineness of these fibers should be 1 to 30 denier, or
The a-fiber length is preferably 0.8 to 5 mm because if it is too short, there will be no flocking effect, and if it is too long, uniform flocking will be difficult.
