[0002]

2. Description of the Related Art Conventionally, as a method for producing a hollow cylindrical three-dimensional woven fabric, for example, an axial yarn, a circumferential yarn, and a radial yarn which is bent and arranged in a radial direction and an axial direction in a plane including the shaft. Japanese Patent Application Laid-Open No. Hei 2-221440 discloses a method in which a three-component yarn is used. Further, there is disclosed a three-dimensional loom in which a yarn fed from a shuttle running in an opening formed by a group of yarns radially arranged around a core material that defines the shape of a woven fabric is wound around the outer circumference of the core material as a circumferential yarn ( JP-A-1-183550, JP-A-1-18350

However, none of the methods can increase the density or make the density uniform because there is no beating mechanism. If the density or density is to be equalized, there is no other way than tightening the thread layers with radial or axial threads. For example, if you do this
The thread will rub other threads, and the thread will fluff. Furthermore, when carbon fiber or glass fiber is used as the thread, this tendency becomes stronger, and the thread is damaged,
In severe cases, it leads to thread breakage. Therefore, in practice, it is not possible to tighten other threads with a thread to increase the density, and even if a thread that is difficult to fluff is used, the density cannot be finished evenly. Further, in any method, the yarns arranged in the circumferential direction and the axial direction of the woven fabric are inserted in parallel in each direction, the communication of the yarns in each direction is not tight, and the action direction of the external force is In some cases, the strength was insufficient.
