Korenek, Auteur ; M. Vondruska, Auteur ; J. Mikulik, Auteur ; Z. Vinklàrek, Auteur Année de publication : 1992 Article en page(s) : p. 75-82 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Recently described PELC stoichiometry has been verified for the reaction between collagen fibres (BAT) and oligoelectrolytes (OEL) and its dependence on reaction conditions, structural and molecular parameters of OEL. It has been found that within a certain region of reaction conditions there occurs a stabilization of the chemical composition of the resultant compound for each of the OEL studied which correspond to stoichiometric polyelectrolyte complex of the pendent-pendent type. As has been shown by measuring the shrinkage temperature of tanned BAT samples their hydrothermal stability rises with the increasing level of irreversibly bound OEL up to the point of formation of a stoichiometric PELC ; hydrothermal stability does not change further with increases in bound OEL above this point (stoichiometry). Further, it has been found that, unlike stoichiometry, hydrothermal stability is significantly dependent on the structural and molecular parameters of the OEL.

Studies on pesticides used for the protection of skins during storage and transportation. Part 1 / P. Golob in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 76, N° 3 (05-06/1992)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 76, N° 3 (05-06/1992) . - p. 83-88 Titre : Studies on pesticides used for the protection of skins during storage and transportation. Part 1 : Protection of goat skins against beetle damage using insecticides in Zimbabwe Type de document : texte imprimé Auteurs : P. Golob, Auteur ; F. V. Robinson, Auteur ; S. Gutu Année de publication : 1992 Article en page(s) : p. 83-88 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Two experiments were conducted in southern Zimbabwe to evaluate the protection afforded to goat skins against beetle infestation by treating the skins with synthetic insecticides. The compounds used were mostly those internationally approved as additives to cereal grains. All treatments provided excellent protection during siw months storage. The chemicals would provide safe, effective alternative to the toxic products currently used to treat skins in many countries. The experiments highlighted the need for confirmation of both the technical and cost effectiveness of treatments on a commercial scale.
