摘要(Abstract):
通过纤维形态分析仪、扫描电镜、X射线衍射仪和热重分析仪对聚对苯二甲酸乙二醇酯(PET)沉析纤维的尺寸大小、表面形貌、结晶性能和热学特性四个方面进行检测分析。结果表明:PET沉析纤维相比市售PET浆粕纤维长度较短,细小纤维含量占70.4%;PET沉析纤维表面分丝帚化现象明显,其外形呈飘带状,形态柔顺,比表面积高达8.009 9 m~2/g;相比浆粕纤维,PET沉析纤维的结晶度和热稳定性相对较高,结晶度为37.88%,初始分解温度365℃,最大分解速率对应的温度为438℃,表明PET沉析纤维具有优异的热学特性,可广泛用于湿法成纸及复合材料增强等领域。
The size, surface morphology, degree of crystallinity and thermal properties of lab-made polyeth-ylene terephthalate(PET) fibrillated fibers were studied by using fiber quality analyzer, scanning elec-tron microscope, X-ray diffractometer and thermogravimetric analysis(TGA). Results indicated that thelength of PET fibrillated fibers was short compared to commercial PET pulp, the fines content accounted for70.4%. It had better fibrous fibrillating, ribbon-like in shape, supple shape and the specific surface area ofup to 8.009 9 m~2/g. PET fibrillated fibers had better thermal performance and crystallinity than that of thecommercial PET pulp, the crystallinity is 37.88 %. The initial decomposition temperature of fibrillated fi-bers was 365 ℃, the maximum rate of decomposition was at 438 ℃, thus demonstrated its excellent thermalproperties, it could be widely used in wet forming paper, composite materials and other fields.
