For example, the folding / extension resistance becomes too large to improve the pleat performance, and the operation feeling at the time of folding / extension is impaired, or the pleat opening angle is increased. Web and thermosetting resin devised as a means to prevent the pleated wire part from returning to its original folded state when it is left for a long time When using a method to obtain the expected performance by peeling or breaking the processing resin agent of the pleated line portion from the web by folding it during pleat processing in combination with the processing agent, the pleated width portion is bent during use. If this occurs, the resin will peel off or break like the pleated wire, leaving a problem in durability. It was. As a specific example of the defect in the latter case, there is a case in which fibrous materials are hardened using a binder, and a paper or a nonwoven fabric is pleated by indentation.

せることができる。[0008] This flat stretching is realized as room temperature processing or heat processing. More preferably, it is realized by hot rolling. As for the method, for example, the pleated portion (8) can be formed on the cloth body (3) using a pleating device (2) as illustrated in FIG. That is, as illustrated in FIG. 1, while the fabric body (3) is being fed in the direction of the arrow shown in the figure, heat-stretching mold blades (4) are provided above and below the fabric body (3), The fabric body (3) is heated and pressurized by pressing the stamper (6) facing the mold blade (4) and the fabric body (3). The heated and pressurized fabric body (3) is accelerated by heating and rapidly plastically deforms. When the stamper is released from pressurization, the fiber yarn of the heated and pressurized portion is shown in an enlarged scale in FIG. It is formed as follows. By setting the temperature of the hot-stretching mold blade (4) at this time near the thermal deformation temperature inherent to the thermoplastic fiber material, plastic deformation can be performed efficiently. Further, by pressing not only the drawing die blade but also the stamper (6), the stamping can be performed more efficiently.

後の折り畳み状態は満足できるものであった。 EXAMPLE 1 A plain woven fabric comprising a polypropylene monofilament yarn (300D) as a warp and a weft was used as a fabric body, the tip of a hot-drawing mold blade was R0.5 mm, and the temperature was raised by applying a current using tungsten as a material. The temperature was kept at about 80 ° C., the plastic deformation was performed by applying pressure with a stamper, and the sheet was treated at a heater temperature of about 100 ° C. while being folded to obtain a pleated fabric. As shown in FIG. 2, a / D is about 0.3.
The drag required for folding and stretching was small, and the folded state after leaving the pleat open angle at 120 degrees for 1200 hours at room temperature was satisfactory.

The drag required for its folding and extension is great,
When the pleats were left at room temperature with the pleat opening angle set to 120 degrees, the folds were not folded after one hour.

る。The pleated fabric of the present invention can reduce the resistance when the pleats are folded or stretched even when a fabric having high rigidity and softness, in other words, a stiff fabric is used. Further, the bending stiffness can be made smaller at the corners of the pleat portion than at the periphery, and the plastic deformation shape is alternately arranged and configured with respect to the neutral axis of the cross section of the fabric body orthogonal to the pleat line of the fabric body. This makes it possible to change the section modulus and make it easier to fold alternately.
The bending direction is not limited to the valley fold or the mountain fold in the hinge-shaped portion. Bending in any direction is possible. The production can be performed easily and easily as compared with conventional pleating.
