    摘要: According to the present invention, the curling or lifting of webs that occurs during the production nonwoven fabrics, and wrinkles that form on the surface of nonwoven fabrics are prevented. Also, the webs can be easily taken off without making grip stronger than necessary. The present invention pertains to an industrial fabric formed by weaving warp and weft, wherein an embossed pattern having a concavo-convex shape is formed in the vicinity of the apex of a knuckle portion exposed on the surface side of the warp and/or weft. In particular, the industrial fabric is characterized in that the warp and/or weft having the embossed pattern are plastic monofilaments.

    摘要: A fiber structure body includes a several fiber layers stacked in a stacking direction and has a multi-axial orientation that includes axial-force directional yarns, orthogonal directional yarns, and intersecting yarns. The fiber structure body includes a flat plate portion and a bend portion that is bent to the flat plate portion and includes a surface intersecting with a surface of the flat plate portion. The axial-force directional yarns are made of continuous fiber of reinforced fiber. Of yarns that form the bend portion and are other than the axial-force directional yarns, yarns that form at least one axis of the bend portion are provided by spun yarns made of discontinuous fiber.
