Titre : A test for bagginess and computer lastometer test Type de document : texte imprimé Auteurs : A. W. Landmann, Auteur ; R. G. Stosic, Auteur ; T. J. Deadman, Auteur Année de publication : 1994 Article en page(s) : p. 105-108 Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Upholstery leather which was originally smooth is often blamed for stretching and becoming wavy after use. This phenomenon is known as bagginess and is a feature for which upholstery tanners in particular would like to be able to test.
The BLC in conjunction with Stable Micro Systems has developed a method which automatically measures the set or bagginess of leathers. The method incorporates the use of a materials tester in conjunction with a purpose built jig and specially written software.En ligne : https://drive.google.com/file/d/1Rjtuh9djI2uMXcybdwF4kg2L-0U58uKV/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8290

Titre : Synthesis and investigation of the composition of model tanning/fatliquoring preparations Type de document : texte imprimé Auteurs : Anita Przepiórkowska, Auteur Année de publication : 1994 Article en page(s) : p. 109-114 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : For several years now we have been working on the synthesis of tanning preparations which also have a full fatliquoring effect on leather 1-6. A chrome (III) salt was used for the synthesis of dual purpose self-emulsifiable preparations as a complex-forming agent. The reaction was carried out in ethylene glycol medium. Dissolving the chromium salt in non-aqueous solvents probably leads to the exchange of water molecules for molecules of the solvent. Such complexes are involved in further reactions of coordination, e.g. with the fat components.
The studies carried out in our laboratory show that the reaction of chromium chloride with sulphoxidised pig fat in ethylene glycol results probably in the formation of complex compounds of chromium with fats or their derivatives.
The dual purpose preparation was used for leather dressing. The compact-tanned leathers contained about 5 % of unextracted fat and were therefore fast to washing in water and organic solvents (dry cleaning). Such a high content of fat fixed in the leather indicates a fatliquoring mechanism different from the traditional one. As sulhoxidised pig fat is an extremely complex chemical system, we intend to provide evidence of the formation of chromium (III) complexes with organic ligands on the basis of studies carried out on model substance.
The purpose of the present study was the use of glycerol tristearate as simple fat for the synthesis of model tanning/fatliquoring preparations and investigation of the effect of non-aqueous solvent on the composition,structure and fastness of the products of reaction of chromium (III) with fats.En ligne : https://drive.google.com/file/d/1552qHLCdKCcNKD15WqdGWF1oonfKY3Dy/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8291
