Abstract
The embodiments of the present invention provide a rubbing roller and a manufacturing method thereof. The rubbing roller comprises a rubbing cloth and a cylindrical roller body. A surface of the rubbing cloth is provided with a tuft array. The rubbing cloth is obliquely wound around the cylindrical surface of the roller body, thereby increasing the density of rubbing loci generated by the tufts. In the embodiments of the invention, with the rubbing cloth obliquely wound around the surface of the roller body, in the rubbing orientation process, the density of the rubbing loci can be increased without increasing the rubbing tuft density of existing rubbing cloth.
