Problems solved by technology

It can be used by cutting according to the length of the roll and the circumference of the roll. Therefore, there is a problem that the pile material is scattered on the cut surface, and single fibers are separated from the base fabric.

Embodiment 1

[0030] woven into figure 1 After the rubbing cloth for LCD is manufactured, it is cut by ultrasonic cutting machine TSC (manufactured by Takaoka Co., Ltd.) at cutting parts AA' and BB'. The frictional heat generated by high-speed vibration melts the cut surface to prevent cracking.

[0031] As a result of rubbing with a rubbing cloth for LCD manufacturing that can prevent the cutting part from fraying, it is possible to manufacture a high-quality LCD that avoids confusion in the rubbing direction caused by fraying, and does not cause a decrease in yield due to yarn dust. .

Embodiment 2

[0033] figure 1 After weaving the rubbing cloth for the manufacture of LCD with the same structure, it is cut by a press OPT-40H-110 (manufactured by Akebono Machinery Co., Ltd.) with a Thomson blade in the cutting section A-A' and BB'. In this case, the paint of the trade name "ピケ" (manufactured by Kawaguchi Co., Ltd.) was applied in a width of 10 mm from the cut surface. Nylon resin is added to "ピケ" to harden the cut surface and prevent it from falling apart. As a result of rubbing with a rubbing cloth for LCD manufacturing that can prevent the cutting part from fraying, it is possible to manufacture a high-quality LCD that avoids confusion in the rubbing direction caused by fraying, and does not cause a decrease in yield due to yarn dust. .

Abstract

The invention discloses a rubbing cloth used for manufacturing LCDs, and a manufacturing method thereof. The rubbing cloth is formed by polyester fiber backing fabric weave and pile yarns which are woven in the backing fabric weave. The edge of the cloth is a cutting surface which is cut for obtaining required size. The cutting surface is provided with an anti-ripping structure. The rubbing cloth used for manufacturing LCDs, preventing a cutting portion from ripping, is used to rub. The cloth prevents chaos of rubbing orientation caused by ripping, and would not cause rate of finished products to reduce by yarn dusts, so as to manufacture LCDs in high grade.

Description

technical field [0001] The present invention relates to rubbing cloths for manufacturing LCDs. In the LCD manufacturing process, an alignment layer is coated on the two substrates that constitute the LCD, and the alignment layer is rubbed in a certain direction and at a certain angle with a rubbing cloth to determine the liquid crystal sandwiched between the two substrates in the subsequent process. direction of the molecule. Thus it can be said that the result of friction itself can affect the display quality of LCD. Obviously, the quality of rubbing cloth is an important factor in determining the quality of rubbing. Background technique [0002] In recent years, LCD displays have been required to be able to display high-definition smartphones and display high-definition images on TVs such as 4K and 8K. Therefore, an LCD display device using an IPS (Inplane Switching; in-plane switching) mode, which is a high-contrast and wide-viewing-angle display mode, is becoming main...
