Description

  The present invention relates to a method for manufacturing a pleated dyed fabric, and more particularly to a method for manufacturing a pleated dyed fabric, which is performed by applying a conventional pleating machine method.

  Currently, the pleating machine method is frequently used for pleating at a factory scale.

  When a pleating process is to be performed on a cloth by the pleating machine method, a pleating apparatus having the following configuration is usually used. An example of a pleating apparatus is described in Patent Document 1, for example.

  First, the pleating apparatus includes a conveyance roller for conveying a cloth to be pleated at a relatively low speed. The peripheral surface of the transport roller is a work surface for arranging the cloth, and the cloth is transported along the peripheral surface as the transport roller rotates. The transport roller also has a built-in heater and also serves as a heating means for heating the cloth.

  In addition, the pleating apparatus includes a pressing member that is urged so as to be in a state in which a cloth is sandwiched between the conveyance roller and the circumferential surface of the conveyance roller and to approach the circumferential surface. The pressing member includes, for example, a pressing belt wound between two pressing rollers, and the pressing belt is disposed so as to cover a predetermined angular range of the peripheral surface of the conveying roller, and is predetermined toward the conveying roller. It is supposed to be in a state of exerting a pressing force. At least one of the two pressing rollers has a built-in heater so that the cloth can be heated via the pressing belt.

  In addition, the pleating apparatus includes a hook forming claw that acts on the cloth while repeatedly reciprocating in the cloth conveying direction at a speed higher than the peripheral speed of the conveying roller so as to form a plurality of wrinkles on the cloth. . The cloth on which the plurality of wrinkles are formed by the wrinkle forming claws is moved according to the rotation of the transport roller while being sandwiched between the peripheral surface of the transport roller and the pressing belt. At this time, the plurality of wrinkles formed on the cloth is held between the peripheral surface of the transport roller and the pressing belt, and the form is maintained. Is set.

  In this way, a pleated fabric is obtained that forms a plurality of folds.

  Conventionally, when a pleated dyed fabric is to be obtained, a desired dyeing process is performed on the fabric in advance, and then the pleating process as described above is performed. In this case, since the dyeing processor and the pleating processor are completely different, when trying to obtain a cloth as a product in which a specific design is dyed and a specific form of pleating is applied, The dealer must dye the desired design on the fabric as a raw material, then transport the dyed fabric to a pleat processor, and then pleat the fabric at a pleat processor. In other words, a relatively long period from order to delivery is required. Therefore, there is a problem that various orders cannot be handled promptly.

  In addition, although said subject cannot necessarily be solved, it is also considered to perform a dyeing process after performing a pleating process. However, when the dyeing process is performed using a normal printing technique, water and heat are used, which may cause a disadvantage that the pleated form set in the pleating process is unraveled or loosened. Therefore, normally, as described above, the dyeing process is performed first, and then the pleating process is performed.

  On the other hand, transfer textile printing using a sublimation dye ink is known as a special textile printing technique. Transfer printing utilizes the property that disperse dyes used for dyeing polyester fabrics sublimate. Transfer paper to which sublimation dye ink composed of disperse dyes is applied is placed in contact with the cloth. This is a textile printing technique in which sublimation dye ink is sublimated and transferred onto a cloth by applying heat while pressing the cloth and transfer paper in a superposed state.

  By using the transfer printing technique described above, a desired pattern can be dyed on a pleated fabric as described in the section “Prior Art” of Patent Document 2. In this case, in advance, The set pleats are not unraveled or loosened.

  However, when the above-mentioned transfer printing technique is applied to a cloth that has been pre-applied with a pleat form, the problem is that the shadow portion hidden by the formation of wrinkles in the cloth is not dyed.
