Can do. Further, the hydrophilic function can be sufficiently exhibited.
- the present inventor considers that the flocking layer formed on the metal plate or the surface-treated metal plate needs to be hydrophilic, and makes this flocking layer hydrophilic.
- a synthetic resin adhesive layer as a short fiber planting layer which is a constituent material of the flocking layer.
- the short fibers are subjected to a hydrophilic treatment, when the electrostatic fibers are implanted with the short fibers, the short fibers must not become short fibers that impair the flight performance.
- the inventor of the present invention notices that the hygroscopicity is equivalent to the hydrophilicity, and does not impair the flying property at the time of electrostatic flocking to the short fiber, so that the maximum hygroscopic property is imparted to the limit.
- a sufficient amount of the moisture absorbing layer is provided so that the moisture absorbing layer has a thickness of 0.5 to 3 m on the surface in order to impart hydrophilicity to the planted flocked layer.
- a hydrophilic treatment layer is formed to form a short fiber that has been subjected to a hydrophilic treatment.
- the hydrophilically treated short fibers are more easily charged than conventional short fibers when performing electrostatic flocking, and thus the amount of charge of the short fibers increases and flies within the electric field during flocking. Since the speed increases, the synthetic resin adhesive layer, which is a short fiber flocking layer, is firmly planted.
- the short fiber implanted in the short fiber planting layer 1 formed as a hydrophilic synthetic resin adhesive layer 1 is subjected to the above-mentioned treatment and is subjected to hydrophilic treatment (treatment that exhibits sufficient hygroscopicity). Therefore, the flocked layer in which the short fibers are implanted has a higher hydrophilicity than the conventional flocked layer. It becomes a flocking layer that can exhibit hydrophilicity and water-absorbing function.
- an adhesive is applied to the surface facing the electrode placed in the electrostatic flocking chamber, and the workpiece formed with the adhesive layer is placed in a grounded state! Then, high-voltage static electricity is applied to the electrode, the short fibers fly in the electric field generated between the electrode and the workpiece, the short fibers are charged, and the short fibers are electrically connected to the electric field in the electric field.
- the short fibers are erected and pierced along an adhesive layer formed on the surface of the workpiece along the direction of the force line.
- the short fibers are implanted by the electrostatic flocking method while moving the workpiece in the electrostatic flocking chamber having a predetermined length at a predetermined speed. If it tries to do so, the short fiber cannot be planted in an upright state due to the relationship between the moving speed of the workpiece and the air resistance caused by the movement, and the so-called fallen hair is implanted.
- the time for staying in the electrostatic flocking chamber of a predetermined length is also limited. In other words, because of the short electrostatic flocking time in the electrostatic flocking chamber, it cannot be planted in the ideal dense planting state.
- the short fibers are originally applied to the hair transplantation target portion of the long metal plate or the surface-treated metal plate that passes through the electrostatic flocking chamber within a predetermined time.
- two electrodes are placed in the electrostatic flocking room and then transplanted.
- a high electric field is formed to form a strong electric field on the entrance side of the electrostatic flocking chamber.

In the process of passing through the electrode, plant in the strong electric field created by the first electrode along the strong electric lines of force as much as possible at the target planting site of the long workpiece as much as possible. I rubbed.
- the second electrode When passing through the first electrode and passing through the second electrode, the second electrode is used to plant the short fibers in the gap between the upright short fibers planted by the first electrode. did. That is, when a long work passes through the first electrode, the first electrode causes electrostatic flocking to be planted firmly by a strong electric field as an upright short fiber that does not fall down the short fiber. The short fibers that are planted with the first electrode firmly standing upright are made into short fibers that serve to prevent hair fall, and then when passing through the second electrode, the short fibers are implanted by the second electrode. In addition, it is a means of performing electrostatic flocking of short fibers with a normal voltage.
- metal plate or surface-treated metal plate When the adhesive is pre-applied to one side of a metal plate or surface-treated metal plate, flocking is performed on the surface of the metal plate or surface-treated metal plate to which the adhesive is applied (front side), and the adhesive is applied to the metal plate or surface-treated in advance.
