| Résumé : |
Dying process in the fur, leather and textile industries generally deal with multi-component systems presenting multi-collinearity and interferent problems. In this case the rational Multiple Linear-Regression (MLR) analysis fails. At TUT in the Laboratory of Fur and Leather Technology (LFLT) fiberoptic spectroscopy with the Partial Least-Squares (PLS) techniques is used to analyse multi-component systems with interferent components and multicollinearity problems and with noisy signals. In order to predict chemical compositions of a multi-component system from spectroscopic information it is necessary to create concentration and absorption matrices which are used to create a calibration model. Using the model and applying PLS data-manipulation techniques it is possible to predict unknown concentrations. In this research the PLS technique is applied in the analysis of acid dying process using a number of dye solutions. The results are promising and possible further applications of this technique are being investigated. |
