Образцы коммерческих тканей с высокой степенью неоднородности исследованы методами лазерно-искровой спектроскопии (ЛИЭС) и хемометрии. Получены данные для характеристики как поверхностных волокон, так и волокон, находящихся в более глубоких слоях материала. Обнаружены заметные различия между спектрами красителей и волокон. Показана возможность сравнения химического состава красителя и волокна вне зависимости от печати ткани. Разработана методика оценки методом ЛИЭС вариаций элементов в составе ткани, позволяющая обеспечить быструю и точную оценку качества и аутентичности образцов.

High heterogeneity solid woven fabric samples were investigated using laser-induced breakdown spectroscopy (LIBS) and chemometrics. Many emission lines were relevant to characterize this material at the surface and in deeper layers of fibers. Differences among dyes and fibers were clearly observed. The scores maps showed the possibility of comparing the chemical compositions of the dye and fiber independent of the print of fabric. Variations in the composition were verified by carrying out a pattern for mapping using a sophisticated LIBS system. This screening can provide a fast evaluation of samples and may associate this information with classification, authenticity or even for forensic analysis of fabric materials.
