ATR技术鉴定二组分混纺纤维

IDENTIFICATION OF BINARY FBER MIXTURES BY THE MEANS OF THE IR - ATR

利用红外衰减全反射光谱技术,检验腈-棉、毛-腈、棉-毛等常见二组分混纺纤维,可获得腈、棉、毛纤维的独立特征峰,其吸光度与纤维的含量之间,具有良好的线性关系.因此,根据ATR谱,不但可以准确鉴别混纺纤维的组成,而且可以准确测定纤维的混纺比.

By using the IR - ATR, we analyzed nitrilon - cotton, nitrilon - wool and coton - wool binary fiber mixtures and acquire its independent peculiar peaks in the spectra, there is a very good linear relation between the ab-sorbance of the peaks and the fiber content. According to the ATR spectra, we can identify accurately the constituent of the binary fiber mixtures and measure accurately its monomer ratio
