PTT纤维与PET纤维鉴别方法的研究

Study on the method to identify PTT fiber and PET fiber

在已知PTT和PET纤维基本结构与性能的基础上,用密度法、熔点法、差热分析法和气相色谱分析法对PTT和PET纤维进行了试验、观察与比较,有效地鉴别出了2种纤维。证明4种方法都可用于PTT和PET纤维的定性鉴别,并分析比较了各方法的优缺点。

Based on their basic structures and characters of PTF and PET, experiments, observations and comparisons are carried on PTT and PET through density and melting point analyses as well as and meteorological chromatographic analyses to effectively identify the two fibers. It has been proved that these four methods can be used for qualitative identification of PIT and PET. The advantages and disadvantages of the methods are also analysed and compared.
