Для извлечения красителя из волокон использованы семь систем растворителей, а также испытаны различные условия экстракции. Для различения текстильных волокон предложены два различных подхода - визуальное сравнение максимумов и хемометрический анализ. Сравнение максимумов в спектрах УФ и видимого диапазонов обеспечивает степень дискриминации 83.6% для хлопковых и 94.3% для шерстяных волокон. Применение хемометрии позволило повысить степень дискриминации до 100% для хлопковых и до 98.1% для шерстяных волокон. Дискриминация в 100% достигается при незначительных величинах t-критерия Уэлша, показывающих, что все образцы различаются. </p></abstract><trans-abstract xml:lang="en"><p>The current study aims at discriminating cotton and woolen textile fibers from dye using UV-Vis spectroscopy and chemometrics methods. For extraction of the dye from fibers, seven solvent systems have been used, and different extraction conditions have also been tested. Two different approaches, i.e., a visual comparison of peaks and chemometric analysis, have been proposed to differentiate between the textile fibers. The comparison of peaks obtained through UV-Vis spectra provides the discrimination power of 83.6% for cotton fibers and 94.3% for the woolen fibers. However, the incorporation of chemometrics has further improved the discrimination power to 100% for cotton and 98.1% for woolen fibers. The discrimination of 100% is achieved with nonsignificant values of the Welch’s t-test, which illustrates that all samples are discriminated. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>текстильное волокно</kwd><kwd>хемометрия</kwd><kwd>спектроскопия УФ-видимого диапазонов</kwd><kwd>судебная экспертиза</kwd><kwd>t-критерий Уэлша</kwd><kwd>textile fiber</kwd><kwd>chemometrics</kwd><kwd>UV-Vis spectroscopy</kwd><kwd>forensic</kwd><kwd>Welch’s t-test</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">M.
