ここで、Ar1はメタ配位又は平行軸方向以外に結合基を有する2価の芳香族基である。
H2N-Ar2-Y-Ar2-NH2 ・・・式(3)
XOC-Ar3-COX ・・・式(4)
XOC-Ar3-Y-Ar3-COX ・・・式(5)
ここで、Ar2はAr1とは異なる2価の芳香族基、Ar3はAr1とは異なる2価の芳香族基、Yは酸素原子、硫黄原子、アルキレン基からなる群から選ばれる少なくとも1種の原子又は官能基であり、Xはハロゲン原子を表す。
(1)目付け
JIS L1096:2010 A法で規定される方法で測定した。
(2)燃焼性
ISO 15025:2000 A法、JIS L1091:1999 A-1法で規定される方法で測定した。
(3)洗濯収縮率
ISO 5077に規定される方法で5回洗濯した後の収縮率を測定した。n数5で経と緯について測定し両者の平均をとった。
(4)乾熱収縮率
ISO 17493に規定される180℃5分間の熱処理を行った際の熱収縮率を測定した。n数5で経と緯について測定し両者の平均をとった。
(5)吸水性
JIS L1907:2010に規定される方法で対象布帛の吸水性能を測定した。
(6)剛軟度
JIS L1096:2010 A法(カンチレバー)に規定される方法で対象布帛の剛軟度を測定した。
(7)制電性
JIS L1094:2014(制電性)により。帯電電荷量を測定した。7.0μC以下を合格とする。
(8)残存溶媒量
原繊維を約8.0g採取し、105℃で120分間乾燥させた後にデシケーター内で放冷し、繊維重量(M1)を秤量した。続いて、この繊維について、メタノール中で1.5時間、ソックスレー抽出器を用いて還流抽出を行い、繊維中に含まれるアミド系溶媒の抽出を行った。抽出を終えた繊維を取り出して、150℃で60分間真空乾燥させた後にデシケーター内で放冷し、繊維重量(M2)を秤量した。繊維中に残存する溶媒量(アミド系溶媒重量)は、得られるM1およびM2を用いて、下記式により算出した。
残存溶媒量(%)=[(M1-M2)/M1]×100
(9)結晶化度
X線回折測定装置(リガク社製 RINT TTRIII)を用い、原繊維を約1mm径の繊維束に引きそろえて繊維試料台に装着して回折プロファイルを測定した。測定条件は、Cu-Kα線源(50kV、300mA)、走査角度範囲10~35°、連続測定0.1°幅計測、1°/分走査でおこなった。実測した回折プロファイルから空気散乱、非干渉性散乱を直線近似で補正して全散乱プロファイルを得た。次に、全散乱プロファイルから非晶質散乱プロファイルを差し引いて結晶散乱プロファイルを得た。結晶化度は、結晶散乱プロファイルの面積強度(結晶散乱強度)と全散乱プロファイルの面積強度(全散乱強度)から、次式により求めた。
結晶化度(%)=[結晶散乱強度/全散乱強度]×100
