Abstract
The present invention provides a rubbing cloth for use in manufacturing liquid crystal display panels which consists of a velvet fabric having a ground sheet texture comprising warps and wefts, and pile yarns woven to the ground sheet texture in the warp direction, wherein synthetic fibers as the warps were woven with combination of different tensions of the synthetic fibers, or the ground sheet texture comprises warps with combination of different feed lengths, so that the pile yarns are stably inclined.
Claims19
A rubbing cloth for use in manufacturing liquid crystal display panels which consists of a velvet fabric comprising:
- a ground sheet texture comprising warps and wefts, wherein the warps are woven to the wefts;
- and
- pile yarns woven to the ground sheet texture in a weaving direction of the warps,
- wherein the warps are composed of warps having different weaving tensions,
- the wefts are arranged to overlap each other by the different weaving tension of the warps when viewed from the top, and
- the pile yarns are held inclined at an inclination at the same angle in one direction along the warp throughout the rubbing cloth by the wefts.

- and
- pile yarns woven to the ground sheet texture in a weaving direction of the warps,
- wherein the warps are composed of warps having a same apparent length in the ground sheet but having different actual lengths which are lengths if the warps are straight,
- the wefts are arranged to overlap each other by the different weaving tension of the warps when viewed from the top, and
- the pile yarns are held inclined at an inclination at the same angle in one direction along the warp throughout the rubbing cloth by the wefts.
