More Information
Summary:PURPOSE: To provide rubbing cloth provided with high wear resistance, a low static charge property and high alignment regulating power. CONSTITUTION: The rubbing cloth for alignment treatment used for rubbing treatment for controlling alignment of liquid crystal molecules has a pile part and a fixing part for fixing the pile part, and fiber formed by using cellulose acetate is contained in the pile part. Crimped bulked yarns can be used as the fiber constituted of the cellulose acetate. The cellulose acetate having 45% degree of acetylation can be used. 본 발명은 내마모성이 높고, 대전성은 낮으며 배향 규제력이 크다는 특성이 겸비된 러빙천을 제공한다. 본 발명의 러빙천에는 액정 분자의 배향을 제어하기 위해 러빙 처리에 사용되는 배향 처리용 러빙천으로 파일부와, 이 파일부를 고정하는 고정부를 갖고, 파일부에는 아세트산 셀룰로오스로 형성된 섬유가 포함되어 있다. 아세트산 셀룰로오스로 이루어진 섬유는 권축이 부여된 필라멘트 가공사를 사용할 수 있다. 아세트산 셀룰로오스는 아세트화도가 45 ％ 이상인 것을 사용할 수 있다.
