摘　　要：应用傅里叶变换红外偏振光谱对涤纶工业丝样品的反式构象含量、非晶取向、整体取向等结构参数进行了表征 。The polarized FTIR was applied to characterize the structure of Poly(Ethylene Terephthalate) (PET) yarn for industrial use.The fractions of trans and gauche conformers,the orientation of PET chain in the amorphous region and the overall molecular orientation of the samples,have been determined.The structure development during the process has been revealed.

关 键 词：偏振红外光谱 PET纤维 聚酯纤维 涤纶 结构表征
