本体を長期にわた９良好に使用することができる。However, the surface layer formed on the nozzle body in this way is
Excellent surface smoothness, i.e., bendability. Therefore, when the surface layer comes into contact with the warp threads when the nozzle main body moves between the warp threads, the nails and threads slide smoothly on the surface layer, so that the nozzle main body does not get caught in the warp threads. Therefore, the warp threads do not stand up, and the texture of the cloth is not impaired. Furthermore, since the surface layer has excellent abrasion resistance, it will not be worn out due to friction with the warp threads. In addition, since the surface layer also has excellent corrosion resistance, it will not be corroded by the water used as the injection fluid. The surface layer can be formed without deteriorating the base material of the nozzle body, and there is no need for finishing after formation. Further, since the surface layer is strongly bonded to the base material and does not peel off, the nozzle body can be used satisfactorily for a long period of time.
