Titre : Process simulation and cost estimation of treatment of chromium-containing leather waste Type de document : texte imprimé Auteurs : Luisa F. Cabeza, Auteur ; William N. Marmer, Auteur ; Eleanor M. Brown, Auteur ; Maryann M. Taylor, Auteur ; Winnie C. Yee, Auteur ; Andrew J. McAloon, Auteur Année de publication : 1998 Article en page(s) : p. 299-315 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Our laboratory has developed two processes to treat chrome shavings, from which protein products and a recyclable chrome cake are isolated. Because of interest from the industry, the authors now describe the estimation of costs of the process. Due to many variables that will have an influence on the cost of the process, we are giving a model for those who would like to estimate their costs of the process. The ultimate their cost evaluation must be calculated by each of the readers, and will depend on the geographical situation, the origin of the chrome shavings and the final disposition of the protein and recycled chrome. As will be discussed, other factors enter into this and use, chemical cost, and more important, use of the protein.

Titre : Polymer impregnation and its effect on the rupture properties of leather Type de document : texte imprimé Auteurs : A. J. Long, Auteur ; Geoffrey E. Attenburrow, Auteur ; Anthony D. Covington, Auteur ; R. G. Stosic, Auteur Année de publication : 1998 Article en page(s) : p. 316-327 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This research concerns an investigation into the impregnation of leather with a polyurethane emulsion as a means of strengthening the grain layer and the grain - corium junction. Since three quaters of the leather produced is used for the manufacture of shoes, a possible application of this research could be the development of direct sticking of shoe uppers to soles without the need for thr current abrasion process.
It was hypothesized tha modification of the leather fiber surface properties to more closely match the polyurethane impregnant would result in an increase in leather strength. It was determined experimentally that the polymer was hydrophobic and so the leather was treated with a waterproofing agent to result in surfaces that were more alikeNote de contenu : - MODIFICATION OF THE POLYMER6LEATHER INTERACTION: Introduction - Method - Results
