ツ２は破損してしまう。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to flexible boots. As shown in FIG. 1, the flexible boot 2 is used to retain all lubricating grease for constant velocity, joint, steering mechanisms, etc., and to prevent dust, water, etc. from entering from the outside. The flexible boot 2 is fixed to the outer ring 6 of the υ joint 5 and the shaft 8 by clamps 4 and 4', and bends and/or twists following the shaft 8. When the flexible boot 2 is bent and/or rolled, the outer circumferential surfaces thereof come into contact with each other and a frictional force is exerted thereon. The flexible boots 2 are made of natural rubber or synthetic rubber, and the songs are and/or
Or, if the flexible boot 2 is rotated at high speed in a twisted state, it will be damaged.

に補強層のためフレキシブルブーツの伸縮性が低下して
、フレキシブルブーツの機能を損なってしまう。In order to prevent this, it is known to use a flexible boot whose outer circumferential surface is coated with a heat-shrinkable material to form a reinforcing layer. However, in this case, it is difficult to bring the reinforcing layer into constant contact with the flexible boot body, and conversely, the reinforcing layer reduces the elasticity of the flexible boot, impairing its functionality.

ブーツである。The present invention has been made with the aim of improving these drawbacks of conventional flexible boots. The flexible boots of the present invention are characterized in that short fibers are flocked on the outer peripheral surface and an elastic forest membrane is formed thereon.
短伊絣材料としては、たとえばナイロン、ポリニスレー
ヨンが好ましい。その長さは０２〜１０闘、デニールは
１．０〜３０が好ましい。Preferred examples of Tani Kasuri materials include nylon and polyester rayon. Preferably, the length is 02 to 10 mm and the denier is 1.0 to 30.
伸縮性抜脱としてはウレタン系のものが望寸しい。A urethane-based material is preferable for elastic release.
コノ発明ノフレキシブルプーツの製造はたとえば次のよ
うに行なう。第２図に基づいて説明する。The flexible pants of this invention are manufactured, for example, as follows. This will be explained based on FIG.
まずフレキシブルブーツ本体１０の外周面をプライマー
処理する。該処理方法としては紫外線処理方法や、トリ
クロロシアヌール酸２％メチレンクロライド溶液による
酸洗方法がある。次いで外周表面に接着剤を塗布する。First, the outer peripheral surface of the flexible boot body 10 is treated with a primer. The treatment method includes an ultraviolet treatment method and a pickling method using a 2% methylene chloride solution of trichlorocyanuric acid. Adhesive is then applied to the outer peripheral surface.
接着剤としてはワレタン系、アクリル系、ゴム系が好ま
しい。またＪ８−ｉ′、 Ｆｚｙは０１〜０６朋が好ま
しい。接着剤塗布後短繊維を植毛し、次いで硬化させる

以上の方法のほかに、機械的方法によって植毛してもよ
い。As the adhesive, valethane-based, acrylic-based, and rubber-based adhesives are preferred. Further, J8-i' and Fzy are preferably 01 to 06. After applying the adhesive, short fibers are flocked and then cured. As for the curing conditions, in addition to the above-mentioned methods, flocking may be performed by a mechanical method.
植毛の上に伸縮性被膜拐料を塗布し硬化させる。Apply an elastic coating material on the flocked hair and harden it.
本発明は以上の−ように構成したので伸縮性を１ｉ】な
うことなく耐摩耗性を向上させることができた。Since the present invention is constructed as described above, the abrasion resistance can be improved without reducing the elasticity.
また、外部から鋭利な５等飛来しても突き刺さることは
ない。Also, even if a sharp 5th grade object comes from outside, it will not pierce you.
