を生じてしまう。 Conventionally, as a method of applying thermoplastic resin powder to a sheet with pores in an arbitrary shape,
As shown in Publication No. 11854, etc., thermoplastic resin powder is first filled into cells of an arbitrary shape in a cylinder, and then a heated sheet is brought into contact with the cylinder to melt the thermoplastic resin powder in the cells. There is a method of attaching the film to the sheet and passing it through an oven to completely adhere. However, this method has the disadvantage that the coating speed cannot be increased because it is necessary to completely melt the thermoplastic resin powder in the cells of the cylinder by contact with the heated sheet. In order to increase the coating speed, it is generally considered to increase the heating temperature of the sheet, but there is a limit due to the material. Moreover, in order to fill the cells of the cylinder with thermoplastic resin powder and squeegee it with a doctor, the cylinder is generally cooled to prevent the thermoplastic resin powder from sticking to the doctor or the cylinder, so it is not heated. The melting efficiency of the thermoplastic resin powder in the cell by the sheet is very poor, and this is also one of the reasons why the coating speed cannot be increased. Here, if the application speed is forcibly increased, a phenomenon occurs in which the thermoplastic resin powder remains in the cells of the cylinder, resulting in variations in the amount of application.

塑性樹脂粉末の処理に苦労する。 Electrostatic powder gravure printing method was first developed in 1964 by Interchemical Co., Ltd. (USA), and uses powder ink (thermoplastic resin powder) instead of liquid ink in conventional gravure printing, and transfers electrically. This is what we do. Thermoplastic resin powder is placed on the printing plate, and the cells are filled with a doctor to remove the thermoplastic resin powder in the non-image areas. Next, after applying a corona discharge to charge the thermoplastic resin powder, the object to be transferred is brought into close contact with the charged thermoplastic resin powder, and an oppositely charged electrode is brought into contact with the charged thermoplastic resin powder from the back side, or a corona discharge is applied. The thermoplastic resin powder in the cell is electrically transferred to the object to be transferred.
However, in this method, if the transferred object is a sheet having pores, the transferred thermoplastic resin powder may escape through the pores of the sheet. The particle size of the thermoplastic resin powder used in electrostatic powder gravure printing is generally 10 to 40 μm, so when printing on cloth, for example, a portion of the powder inevitably passes through the grain of the cloth. Therefore, the amount of coating is not constant, and it is difficult to dispose of the thermoplastic resin powder that has passed through.

The surface of the thermoplastic resin powder is softened or melted by contacting the sheet with the thermoplastic resin powder, and the thermoplastic resin powder is attached to the sheet surface, blocking the pores of the sheet, and then corona discharge or high voltage is applied from the back side of the sheet. The present invention provides a method for completely transferring thermoplastic resin powder filled in a cell without spilling it through the pores.

Ozokerite, also called other wax, is a naturally occurring mineral wax. Petroleum waxes include paraffin wax, microcrystalline wax, and petrolactam, depending on the manufacturing route and properties. Furthermore, polyethylene wax and amide wax, which have a molecular weight between that of paraffin wax (wax) and polyethylene, are also classified as solid waxes in a broad sense.

部分と粉末の状態のままの部分を有している。 Hereinafter, the present invention will be explained in detail using the drawings. As shown in FIG. 1, a sheet 1 having holes is heated by a heating drum A2, and then sent to a cylinder 3 which is water-cooled. On the other hand, the dot-shaped cells 7 of the cylinder 3 are filled with the thermoplastic resin powder 5 in the hopper 4 by the doctor 6, and the thermoplastic resin powder 5 in the cells 7 is charged with an electric charge by the corona charger A8. , the sheet 1 having pores heated by the heating drum A2 and the thermoplastic resin powder 5 in the cells 7 are brought into contact with each other, and the thermoplastic resin powder 5 on the contact surface is softened or melted to form the sheet 1 having pores. The thermoplastic resin powder 5 is attached to the surface. At this time, as shown in an enlarged view in FIG. 2, only the portion of the thermoplastic resin powder 5 in the cell 7 that comes into contact with the porous sheet softens or melts, and the thermoplastic resin powder in the bottom portion of the cell 7 softens or melts. No. 5 remained in the powder state. Next, a corona discharge with a polarity opposite to that given by the corona charger A8 is applied by a corona charger B9 from the back side of the sheet 1 having holes, or a conductive roll (not shown) is charged with a high charge. By applying a voltage, the thermoplastic resin powder 5 filled in the cells 7 is completely transferred to the sheet 1 having pores. At this time, the thermoplastic resin powder 5 transferred to the sheet 1 having holes has a portion attached to the sheet 1 having holes and a portion remaining in a powder state.

きる点で優れている。 According to the present invention, thermoplastic resin powder is filled into cells of an arbitrary shape of a cylinder, and then a heated sheet having pores is brought into contact with the cylinder to soften or melt the thermoplastic resin powder in the cells. Compared to the method of adhering to a sheet with holes and then passing it through an oven to completely adhere, the combined use of electrostatic force increases the application speed, resulting in improved productivity.
This method is excellent in that the heating temperature of a sheet having pores can be lowered.

落ちるような現象は生じない。 Furthermore, since the thermoplastic resin powder inside the cell can be completely transferred, the amount of application becomes uniform, which not only improves the quality of the product but also makes maintenance easier. Furthermore, when thermoplastic resin powder is printed on a sheet with pores using electrostatic powder gravure printing, a portion of the thermoplastic resin powder passes through the pores of the sheet, but in the present invention, a preheated sheet with pores is brought into contact with a cylinder. After softening or melting the surface of the thermoplastic resin powder in the cell and attaching it to the sheet with pores, electrostatic force is used to transfer all of the thermoplastic resin powder in the cell to the sheet with pores. Since this method transfers and coats the thermoplastic resin powder onto the sheet, there is no possibility of the thermoplastic resin powder spilling out from the pores of the sheet.

On the other hand, in a cylinder having dot-shaped cells of 40 dots/inch with a depth of 120μ and a width of 420μ, polyester resin powder with a particle size of 10 to 40μ was filled into the cells by a doctor, and the cells were charged with a negative charge by a corona charger. A corona discharge (-6kV) is applied to give a negative charge to the polyester resin powder inside the cell. Next, as the cylinder rotates, the polyester fiber base fabric heated by the heating drum is brought into contact with the cylinder.

Conventional methods that do not apply corona discharge have a maximum coating speed of 20 m/min.
