摘要/Abstract

摘要： 为促进光谱指纹防伪纤维的应用推广，本文制备9种纤维样品，借助荧光分光光度计对其防伪特性进行了研究。结果表明：在特定的激发光下，不同原料配方和纺丝工艺参数下纺制的光谱指纹纤维具有的发光谱线类似人的指纹，具有唯一性；经重复测量，该发光谱线具有很好的再现性；存放6个月，水洗2h，或光照5h、或经120℃高温处理2h、或2min酸碱处理后，该发光谱线没有发生变化；存放12个月后发光强度降低0.7%；酸碱处理5min后发光强度降低超过10%，但发光波长均未发生改变。因此，在使用的过程中尽量保持存储环境的干燥，避免酸碱的长时间侵蚀。

Abstract: To promote the application and popularization of spectrum-fingerprint anti-counterfeiting fiber, in this paper, 9 kinds of fiber samples were prepared and the anti-counterfeiting characteristics of the fiber were studied with the help of fluorescence spectrophotometer. The results showed that spectrum-fingerprint fibers made by different raw materials and spinning process parameters had different emission spectra when excited with specific exciting light, which were unique, just like the fingerprint of human beings. The emission spectral curve of spectrum-fingerprint fiber had excellent reproducibility after repeated measurement and had no observable change happening after being stored for 6months, washed for 2hours, light for 5hours or being treated for 2hours by 120℃ tempreture, acide or base for 2minutes. But the emission intensity decreased by 0.7% after being stored for 12months and by over 10% after being treated by acide or base for 5minutes，meanwhile the emission wavelength had no change. Therefore the fiber should be stored in a dry environment and prolonged treatment should be avoided in application.
