Description
図1は、本発明の一実施形態に使用する装置を示すものである。ラビングロール1はその表面にラビング布2が貼り付けられており、毛足3が出ている。金属表面ロール4は金属表面5を有している。
また、ディスコティック液晶化合物としては、トリフェニレン系、トルクセン系等が挙げられる。
さらに、液晶物質中に熱または光架橋反応等によって反応しうる官能基または部位を有している各種化合物を液晶性の発現を妨げない範囲で配合しても良い。架橋反応しうる官能基としては、ビニル基、(メタ)アクリロイル基、ビニルオキシ基、エポキシ基、オキセタニル基、カルボキシル基、水酸基、アミノ基、イソシアナート基、酸無水物等を挙げることができる。
実施例で用いたラビングロールを実施例の調整処理をしないで、実施例と同様にしてラビングした。
得られた長尺の液晶性高分子層について、下記の評価方法によって配向ムラの有無および欠陥数を観察したところ、実施例のフィルムを用いたものには配向ムラおよび欠陥はほとんど認められなかった。一方、比較例のフィルムは全面的に配向ムラが観察され、欠陥数は10個/m2以上であった。
式(1)の液晶性高分子物質(対数粘度=0.22dl/g、Tg=61℃)、及び式(2)の(R)−3−メチルヘキサン−1,6−ジオール単位を含む光学活性な液晶性高分子物質(対数粘度=0.17dl/g)を合成した。
これらの高分子材料の合成は、オルトジクロルベンゼン溶媒中、トリエチルアミンの共存下で、ジカルボン酸単位に対応する酸塩化物とジオール化合物とを反応させることによって行った。
得られた式(1)の液晶性高分子物質18.1g及び式(2)の液晶性高分子物質1.9gの混合物を80gのN−メチルピロリドンに溶解させて液晶性高分子物質溶液を調製した。
(1)液晶性高分子の対数粘度測定
ウッベローデ型粘度計を用いて、フェノール/テトラクロロエタン(60/40重量比)混合溶媒中、30℃で測定した。
(2)配向ムラおよび欠陥検査の観察
配向ムラ観察はオリンパス光学(株)製BH2偏光顕微鏡を用いて行った。
(3)液晶性高分子の組成の決定
液晶性ポリエステルを重水素化クロロホルムに溶解し、400MHzの1H−NMR(日本電子製JNM−GX400)で測定し組成を決定した。

Claims (1)
- ラビングロールのラビング布の毛足を、金属表面を有するロールであって、該金属表面を有するロールの径:該ラビングロールの径が0.5〜3.0の関係にあるロールの該金属表面に接触させて、該ラビングロールを一方向に回転し、吸引装置の先に設けた微粒子測定器で測定される微粒子が実質的に認められなくなるまで該毛足の方向をそろえることを特徴とするラビングロールの調整方法。
