Description
本発明における芳香族ポリエステルには、紡糸に適した分子量範囲が存在する。この溶融紡糸条件に適する分子量に対応する物性値として「流動開始温度」を用いる。「流動開始温度」は、島津製作所製のフローテスターＣＦＴ−５００を用い、径１ｍｍ、長さ１０ｍｍのノズルで、圧力１００ｋｇ／ｃｍ ２ の状態で、芳香族ポリエステル試料を４℃／分で昇温し、試料がノズルを通って流動し、かつ４，８００パスカル秒の見かけ粘度を与える温度で定義される。
The aromatic polyester in the present invention has a molecular weight range suitable for spinning. “Flow start temperature” is used as a physical property value corresponding to the molecular weight suitable for the melt spinning conditions. “Flow start temperature” is a temperature tester using a flow tester CFT-500 manufactured by Shimadzu Corporation, with a nozzle having a diameter of 1 mm and a length of 10 mm and a pressure of 100 kg / cm 2 and raising the temperature of the aromatic polyester sample at 4 ° C./min. And the temperature at which the sample flows through the nozzle and gives an apparent viscosity of 4,800 Pascal seconds.
