Description of the Related Art Polyacrylonitrile-based oxidized fiber spun yarn woven fabric is excellent in heat resistance and heat insulation and is used as a sheet-shaped heat and heat insulation material. In addition, the polyacrylonitrile-based oxidized fiber spun yarn woven fabric is useful as an intermediate raw material for polymer fuel cells, because it is obtained as a thin sheet-like carbon material by improving the electrical conductivity by carbonization.

ことなく織り返して織物とする。The polyacrylonitrile-based oxidized fiber spun yarn woven fabric is obtained by processing the polyacrylonitrile-based oxidized fiber spun yarn by a shuttle method or the like.
In the case of the shuttle type, the weft is not cut at the end of the fabric and the fabric is woven back into a fabric.

発生する等のトラブルが生じる。However, in the case of the shuttle type, when the weft yarns are woven back at the end portions of the fabric, the tension of the weft yarns causes the warp yarns at the end portions to be cut or the fabric to shrink in the width direction, resulting in The width and thickness are likely to be uneven. If the width unevenness occurs, the manufactured oxidized fiber spun yarn woven fabric is rolled up into a roll and shipped as a product, and the ends are not uniform, which is a poor quality product. Further, the width unevenness causes troubles such as occurrence of threads at the time of carbonization, catching the end of the fabric in the guide part or the inside of the carbonization furnace, cutting of the fiber, and generation of carbon fiber powder at the end. Occurs.

Furthermore, when performing compression processing, it is difficult to perform compression with a uniform pressure, and there is a problem in that the thickness of the woven fabric becomes uneven after processing.
