摘要 用X衍射、扫描电镜、差热分析、光学显微镜对共混丙纶的形态、结构进行了研究。结果表明,P-36D/PP和P-528/PP共混丙纶,均为基体-微纤型两相结构。P-36D和P-528的加入,对共混丙纶的结晶性影响不大,对形态结构有很大影响。共混丙纶的亲水性(吸湿性和保水性)与纤维的形态、结构、组成高聚物的性质以及共混比有着密切关系。 P-528/PP共混丙纶的亲水性,明显高于P-36D/PP共混丙纶。 The morphology and structure of P-36D/PP and P-528/PP blended polypropylene fiber were investigatedby means of X-ray diffraction, SEM, DTA and optical microscope. Results show that the PP blended fiber isa matrix-fibril biphase structure. The introduction of P-36D and P-528 to PP has no significant effect on crys-talline structure of the fiber, but the morphological structure of the fiber is greatly influenced. The hy-drophilicity (hydroscopicity and hydro-retain property) of the PP blended fiber is closely related to its mor-phological structure, composition, blent ratio as well as nature of the polymer. The hydrophilic property of P-528/PP blended fibre is superior obviously to that of P-36D/PP fibre.
