Elliott, Auteur Année de publication : 1986 Article en page(s) : p. 129-134 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The background and activities of the once thriving industrial leather production of the United Kingdom is described, with reference to the history of a typical small company engaged in this field. Some reasons are proposed for the over-decline of the industry, together with a plea for increased recognition of the capabilities of the remaining producers and their relevance to the leather industry as a whole.

Titre : Tannin analysis - A 130 year problem Type de document : texte imprimé Auteurs : T. Waite, Auteur Année de publication : 1992 Article en page(s) : p. 187-194 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Attempts to establish a workable method of evaluating the strength of vegetable tanning materials go back to the early part of the 19th century but the first method to achieve any real credence was that of Löwenthal developed in the 1860s. The problem was first addressed on an international scale at the London meeting of 1897 at which the first leather chemist’s society was founded. Many subsequent meetings have failed to produce agreement on an international method of analysis, making this subject the longest standing source of dispute on the international leather scene. This paper discusses the three Official Methods which currently co-exist, highlights some of the problem areas and makes some suggestions about their resolution. A more recent problem has been the use of these methods for estimating the tannin content of syntans, a purpose for which they were not originally envisaged and are unreliable, but for which no serious alternative have yet been promulgated.
