Rubbing cloth and production of the rubbing cloth



PURPOSE: To make it possible to suppress the occurrence of peeling and flaws of an orientation control film and to uniformly maintain rubbing performance even in the case where many rubbing treatments are executed. CONSTITUTION: Since the twists in the front end side parts A of rubbing yarn 5,... are loosened, foreign matter is hardly held in these part A and, therefore, the formation of flaws is suppressed even at the time of the rubbing treatment. Since the twists of the front end side parts A are loosened, the state of these parts does not change even in the case where the many rubbing treatments are executed and eventually, the rubbing performance is maintained constant and the change in the orientation regulating power to be imparted is suppressed.
