きる。[Effects of the Invention] According to the present invention, since spinning and molding are performed simultaneously by the melt blow method, three-dimensional molded bodies of various shapes made of ultrafine fibers can be efficiently produced by simply changing the molding base material. Moreover, since there is no need for post-molding treatment using a mold or the like, a bulky three-dimensional molded article with good moldability without wrinkles can be obtained. Furthermore, since the ultrafine fibers and the molding base material can be thermally bonded, a molded article with greater strength can be obtained.
以 上that's all
