Titre : Characterization and evaluation of four types of finish topcoats Type de document : texte imprimé Auteurs : Anna Bacardit, Auteur ; T. Canals, Auteur ; Mira Cobos, Auteur ; A. Shendryck, Auteur ; O. Solé, Auteur ; Lluis Ollé, Auteur Année de publication : 2009 Article en page(s) : p. 130-139 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The aim of this work is the characterization and evaluation of four types of topcoats used in leather finished leather samples using the same products. The samples were tested in the laboratory to evaluate their physical resistances and fastness properties.
A comparison of results shows that all the products studied for each type of topcoat present practically the same functional groups ; there are no significatn differences between the recorded spectra of each of the products in a group and the spectra once they have been applied to the leather. In addition, there are no significant differences in the physical resistances and fastnesses obtained, except for the organoleptic properties (level of gloss, feel, etc.). However, strong evidence seems to indicate that topcoat improves wet properties of the finished leather. Moreover, the study of th IR spectra bothy of the products and finished leather samples after an accelerated ageing test provides more objective date rather than that obtained from traditional methods.En ligne : https://drive.google.com/file/d/1dtpmNCmm-frnElkxvFF1NHmiOWmwsrI-/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=6102

Spectrométrie infrarougeIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The finishing process is one crucial steps in the process by which the tanning industry transforms leather into an end-product. Therefore, ensuring the required quality in the product requires careful control of this step. Traditionally, the leather tanning industry has used polluting processes ans slow analytical methods involving time-consuming separations and aslo, frequently, the use of environmentally unfriendly reagents. In this work, we used a large matrix of spectroscopic data obtained from 63 leather specimens (34 from Pielcolor and 29 from the laboratories of the Leather Technology School of Igualada) to develop a method allowing the finshing method identified with the need for no sample treatment. To this end, Fourier transform infrared (FTIR) spectra were recorded with the aid of an ATR module and near-infrared (NIR) spectra with a fibre-optic probe. Chemometric processing of the FTIR or NIR spectral information thus obtained by Principal Component Analysis (PCA) and Canonical Variate Analysis (CVA) allowed the identification of the finishing treatment used on the studied leather samples. The results for the external prediction set (80 % o hits with the FTIR model and 60 % with the NIR model) were of the same order of mgnitude than those obtained by leave-one-out cross-validation of the calibration set (85 % with FTIR and 72 % with NIR).

Titre : Control analyses of industrial leather dyestuffs using a rigid multicomponent calibration method Type de document : texte imprimé Auteurs : M. Blanco, Auteur ; T. Canals, Auteur ; J. Coello, Auteur ; J. Gené, Auteur ; H. Iturriaga, Auteur ; S. Maspoch, Auteur Année de publication : 1996 Article en page(s) : p. 110-113 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : A rigid multivariate calibration for the simultaenous determination of the components of dye baths for crust tanned crossbred sheep skin was developed. The ensuing analytical method allows dyes to be quickly quantified from the UV-Vis spectrum. The fixation of each bath component was monitored over time as a function of temperature.
