Problems solved by technology

Therefore, it is easy to denature due to the frictional heat generated during grinding, and it is not durable as a grinding cloth
In addition, as described in JP-A-6-194661, the abrasive cloth made of casein has the problem of easy denaturation due to the frictional heat generated during grinding due to the casein protein.

Embodiment Construction

[0019] The inventors of the present invention used various fiber materials to try out abrasive cloths, and as a result of intensive research, it was found that by using acetate fibers in the fluff part, it is possible to obtain a cloth having the characteristics of large orientation adjustment force, high wear resistance, and low chargeability. The abrasive cloth, the following hereby specifically describes the present invention.

[0020] Such as figure 1 As shown, the abrasive cloth 2 of this embodiment is a raised cloth having piles 3 for raising fibers, a base fabric 6 for fixing them, and an undercoat layer 7 , and acetate fibers are contained in the pile yarns constituting the piles 3 .

[0021] Acetate fiber is a fiber made of cellulose acetate, which is cellulose acetate represented by the following chemical formula:

[0022] [C 6 h 7 o 2 (OCOCH 3 ) x (OH) 3-x ] n (where, 0

[0023] Among them, as long as it can be processed into a fibrous form, it does no...

Abstract

A rubbing cloth used for rubbing to control the alignment of liquid crystal molecules. The rubbing cloth comprises; the pile portion containing fibers comprising a cellulose acetate. The fibers comprising a cellulose acetate may be textured filament yarns provided with crimps. The cellulose acetate may have an acetylation degree of 45% or more. The rubbing cloth can have properties of great alignment force, low frictional electrification, and high wear resistance together.

Description

technical field [0001] The invention relates to a grinding cloth used for controlling the orientation of liquid crystal molecules in the process of manufacturing liquid crystal panels. Background technique [0002] A liquid crystal display component for a transmissive liquid crystal display device, including a TFT substrate of a driving component (TFT) composed of a thin film transistor, and a color filter substrate (hereinafter referred to as a CF substrate) formed with a color filter separated by a Arranged facing each other at tiny intervals, and liquid crystals are sealed in the gaps. On the surface of the TFT substrate, patterned ITO electrodes serving as pixel electrodes are arranged, and an alignment film is arranged to cover the ITO electrodes. On the other hand, an ITO film as a common electrode is arranged on the surface of the CF substrate, and an alignment film is arranged on the surface of the ITO film. The TFT substrate and the CF substrate are arranged facin...
