为进一步优化异染FDY涤纶的纺丝工艺和改善异染FDY涤纶的质量提供理论依据,设计了不同规格的FDY,利用扫描电镜、声速纤维取向度测量仪、差式扫描量热仪和强力仪对其进行性能测试。结果表明:一步法异染FDY具有不均匀分布的粗节与细节,即普通FDY截面较为均匀,异染FDY纱线粗细不一,其取向因子值比普通FDY纤维略小,而其沸水收缩率大于普通FDY的沸水收缩率;材料的玻璃化温度、结晶温度和熔融温度的大小顺序均为普通FDY>异染FDY细段>异染FDY粗段;异染FDY的断裂伸长率比普通FDY大,其断裂强力相对下降。

为给熔喷非织造材料的制备提供理论参考,采用熔融共混的方法分别制备了质量比为100∶0、75∶25、50∶50、25∶75、0∶100的熔喷用聚(3-羟基丁酸-co-3-羟基戊酸共聚酯)/聚丙烯接枝马来酸酐(PHBV/PP-g-MAH)共混材料。利用差示量热扫描仪、X射线衍射仪和红外光谱仪分别对PHBV/PP-g-MAH共混体系的相容性进行了研究,并用扫描电镜观察了共混体系的相分布形态。结果表明:共混体系出现了分离的玻璃化温度,表明2种组分总体不相容;在衍射角22.8°处没有出现PHBV的衍射峰,说明PP-g-MAH改变了PHBV结晶区的分子链排列;在1 710 cm-1处共混体系出现新的吸收峰,即二者之间的化学键生成了酯基;当共混比例不同时,共混体系呈现不同的"海-岛"相分布形态。

剪切黏稠液体(STF)是一种非牛顿流体,采用SiO2作为分散相微粒,极性溶剂聚乙二醇作为分散介质。用流变仪测量了STF分散体系中SiO2固含量为10%、15%、20%、25%、30%、35%、40%和45%的稳态流变性能以及进行了剪切黏稠性能的可逆性分析。结果表明:随着剪切速率的增加,STF分散体系先出现剪切变稀现象,当剪切速率超过某个临界值时,分散体系出现急剧增稠现象;在剪切速率由小到大和由大到小变化时,2条扫描曲线基本重合,表明STF分散体系的剪切增稠效应具有可逆性。
