Titre : Heterogeneous interaction between sulpho-syntans and collagen, part 7 : Polyionic network hypothesis Type de document : texte imprimé Auteurs : Z. Vinklà rek, Auteur ; Z. Korenek, Auteur ; J. Vaculik ; M. Vondruska Année de publication : 1992 Article en page(s) : p. 162-168 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : During the reaction between oligoelectrolyte and collagen, a polyelectrolyte complex of the pendent-pendent type is formed. This kind of intermolecular complex has the structure of a three dimensional polyionic network, which is only intrafibrilliary polyionic network has been discussed theoretically. The structure of collagen compounds with oligoelectrolyte on the basis of naphthalene-2-sulphonic acid condensed with formaldehyde (syntanin) has then been followed up experimentally by scanning electron microscopy (SEM) and its correspondence to theroretical assumptions has been discussed.

Titre : Softness - an international comparison of manual assessment against instrumental methods Type de document : texte imprimé Auteurs : A. W. Landmann, Auteur ; R. G. Stosic, Auteur ; J. Vaculik, Auteur ; M. Hanson, Auteur Année de publication : 1994 Article en page(s) : p. 88-92 Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : An international "round robin" trial has been carried out to investagate the ability of a number of instruments to objectively measure leather softness. Also investigated was the inter-laboratory variation of the instruments tested.
Results show that as the softness range of a pack of leathers narrows, the variation of softness rankings by assessors increases. The average of the rankings of nine assessors was used to assess the ability of each instrument to measure leather softness. The instrument which performed the best in this trial was the BLC's ST300 softness tester. This instrument is also non-destructive in its application and an order of magnitude quicker in its operation (as no sample preparation is required).En ligne : https://drive.google.com/file/d/19AHK63MZOoNEfRFSsM_iKrhrqYNziobH/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8382
