在这项研究中，通过同步辐射微束X射线荧光（SR - μ - XRF）分析完成了单个白色聚酯服装纤维的无损鉴别。垂直聚焦SR - μ - XRF是一种有效的无损分析方法。利用Kirkpatrick-Baez （KB）反射镜垂直聚焦20 keV X射线，对日本市场上常见的22种白色聚酯纤维进行分析。垂直聚焦2 μm (V) × 300 μm (H)光束的SR‐μ‐XRF检测单个光纤中元素的灵敏度比未聚焦300 μm (V) × 300 μm (H)光束的SR‐μ‐XRF高12.8倍。SR - μ - XRF方法的最低检出限（MDLs）分别为Cl 8.15 ppm和Br 0.06 ppm。除tio2消光剂中的Ti外，还在单个纤维中检测到消光剂中的Zr和Nb杂质。在单个纤维中还检测到聚合催化剂中的Sb和酯交换催化剂中的Co。比较TiKβ/SbLα、β和ZrKα/ nbk α的x射线强度比是区分单个服装纤维的有效方法，当添加微量元素作为区分指标时，98%的纤维被区分出来。
In this study, the nondestructive differentiation of individual white polyester clothing fibers was accomplished via synchrotron radiation microbeam X‐ray fluorescence (SR‐μ‐XRF) analysis. SR‐μ‐XRF with vertical focusing is a useful nondestructive method for the analysis of a single polyester clothing fiber. Kirkpatrick–Baez (KB) mirror was used to vertically focus 20 keV X‐rays for the analysis of 22 individual white polyester fibers taken from clothing commonly sold in Japan. SR‐μ‐XRF with a vertical focused 2 μm (V) × 300 μm (H) beam was approximately 12.8 times more sensitive than SR‐XRF with an unfocused 300 μm (V) × 300 μm (H) beam for the detection of elements in single fibers. The minimum detection limits (MDLs) of the SR‐μ‐XRF method were 8.15 ppm for Cl and 0.06 ppm for Br. In addition to Ti in TiO2delustering agents, Zr and Nb impurities in the delustering agents were detected in individual fibers. Sb from a polymerization catalyst and Co from a transesterification catalyst were also detected in individual fibers. Comparing the TiKβ/SbLα,βand ZrKα/NbKαX‐ray intensity ratios was a useful way to distinguish individual clothing fibers, and 98% of the fibers were differentiated when additional trace elements were used as discrimination indicators.
