Titre : A new enzyme process for improved yield and softer leather technical note Type de document : texte imprimé Auteurs : Mihai Deselnicu, Auteur ; Victoria Bratulesco, Auteur ; Marcel Siegler, Auteur ; Andrei Anghel, Auteur Année de publication : 1994 Article en page(s) : p. 352-356 Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The main purpose of bating is to remove the noncollagenous proteins to make the leather softer with greater stretch. Failure to remove the noncollagenous proteins causes a cementing together of the fibres when the leather is dried and results in firmness and lack of flexibility. It is weel known that the classical bating process in the alkaline condition makes use of proteolytic enzymes, which are of pancreatic or baterial origin, and the efficient/activity of the process depends on the enzyme concentration as well as temperature, pH, and time during the bating process. Therefore, the enzyme treatment in alkaline conditions is considered a very sensitive process.
A new development in this field is the use of the enzyme, pepsin, which is extracted from bovine or porcine stomach mucous and is active in acid condition.Treatment with this enzyme under acid conditions may be done after the pickle process or after the chrome tanning.The treatment is safer and has a more selective action than the classical bating under alkaline conditions.By treating the shaved wet blue hides with the acidic enzyme not only are the advantages of improved yield and softer leather achieved, but uniformity of quality and physical properties are also achieved.En ligne : https://drive.google.com/file/d/1whd94jRnEAhyTxxUplbz94PRs0GkrAMv/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8041

ConfitageLe confitage est une action biochimique effectuée au moyen de produits enzymatiques, qui a pour but de dégrader les fibres élastiques, contribuant ainsi à augmenter la souplesse du cuir. En outre, les enzymes complètent la dégradation des résidus épidermiques, donnant ainsi une fleur plus propre et plus lisse.

PicklageLe picklage consiste à faire absorber à la peau en tripe une quantité importante d'acide, en présence de sel neutre (NaCl) pour réprimer le gonflement que provoquerait l'acidité du milieu.
TannageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The continuous development of leather substitutes, including poromerics and coated fabrics, the increased price of hides, greater quantities of shoe imports, and, finally, the considerably higher cost of U.S. labor have forced American tanners to re-evaluate completely their tannery concepts. Today, to be competitive with European and other foreign tanneries, South American, for instance, we must have modern processes providing higher productivity and better leather quality.
Therefore, most of the larger tanneries are now involved in rationalizing their production, and in simplifying and modernizing their processes. Some years ago, a two-day beamhouse lime split process, followed by a bate-pickle-and-chrome-tan run in drums, over a period of 15 to 17 hours, would be considered a classical procedure. In the meantime, however, almost all tanneries have attempted to shorten their processes and at the same time change their system to blue splitting.Note de contenu : - Rapid unhairing processes

These chemicals are essential in leather manufacture to ensure that the leather is not degraded by mold growth and to safeguard the leather’s quality, usefulness and commercial value. Over the years the use of some fungicides has been disallowed due to their toxicity or other issues, while others may be restricted in the future. Consequently, tanners are faced with a more limited number of products to choose from when it comes to these chemicals. In an effort to address this need, Zenith undertook a development project that led to a product specifically designed for the leather industry, which has good fungicidal effectiveness, an acceptable toxicology/eco profile and competitive cost. This paper provides an overview of the performance characteristics of this new leather fungicide.
