摘要
研究了易染阳离子染料可染聚酯（ECDP）／聚对苯二甲酸丙二醇酯（PTT）共混物的相容性及其流变性能。结果表明：ECDP／PTT共混物在无定形区相容性良好，在晶区晶相分离；ECDP／PTT共混物在剪切速率为10^2-10^5s^-1时属于切力变稀流体；纺丝温度245℃时，ECDP／PTT共混物具有良好的可纺性，ECDP／PTT质量比为60／40时，所得纤维断裂强度最低。
The miscibility and rheological behavior of easy cationic dyeable polyester （ECDP）/polytrimethylene terephthalate （PTT） blend were studied. The results showed that ECDP/PTT blend had fairly good miscibility in amorphous region, but appeared crystal phase separation phenomenon in crystal region. ECDP/PTT blend belonged to shear thinning fluid at the shearing rate of 10^2 - 10^5 s^-1. ECDP/PTT blend had fairly good spinnability as the spinning temperature was 245 ℃. ECDP/PTT blend fiber had the minimum breaking strength as the ECDP/PTT mass ratio was 60/40.
