5. The control device of claim 4, wherein the static eliminator is an ion blower or an X-ray generator.
6. The control device according to claim 5, further comprising a conveying device for conveying the rubbing-cloth in a preset direction.
7. The control device according to claim 3, wherein the first positive electrode plate and the first negative electrode plate have equal widths in a length direction of the rubbing cloth;
and/or the widths of the second positive electrode plate and the second negative electrode plate along the width direction of the friction cloth are equal.
8. The control device according to claim 7, wherein a pitch between the first positive electrode plate and the first negative electrode plate is equal to a pitch between the second positive electrode plate and the second negative electrode plate.
9. A method for controlling the cloth pile direction of the rubbing cloth using the cloth pile direction control apparatus of any one of claims 1 to 8, comprising:
providing electric charge for the cloth hair of the rubbing cloth;
providing a transverse electric field for the cloth wool with the charges, and solidifying the raising agent on the cloth wool after the cloth wool with the charges inclines along the direction of the transverse electric field;
and providing a longitudinal electric field for the cloth wool with the charges, and solidifying the raising agent on the cloth wool after the cloth wool with the charges inclines along the direction of the longitudinal electric field.
10. The method according to claim 9, further comprising, after the step of solidifying the raising agent on the cloth hair after the electrically charged cloth hair is tilted in the direction of the transverse electric field: eliminating the charge on the cloth hair;
and after the charged cloth hair is inclined along the direction of the longitudinal electric field and the raising agent on the cloth hair is solidified, the method further comprises the following steps: eliminating the charge on the cloth hair.
