Drying your leather without shedding tears / A. W. Landmann in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 78, N° 2 (03-04/1994)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 78, N° 2 (03-04/1994) . - p. 44-45 Titre : Drying your leather without shedding tears Type de document : texte imprimé Auteurs : A. W. Landmann, Auteur Année de publication : 1994 Article en page(s) : p. 44-45 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Drying is the separation of liquid from solid. A number of methods for achieving this are considered not only with efficiency and economy but also taking into consideration the quality of the resultant leather. There are no unique methods which will optimise the results and so each productiondeserves individual analysis to achieve the desired result in the most cost effective way.

Rocrelle, Auteur ; Antoine Gaset, Auteur ; N. Caruel, Auteur ; A. Darnaud, Auteur Année de publication : 1994 Article en page(s) : p. 46-49 Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The scale-up of a new tanning process in organic solvent medium is described. A pilot scale plant was constructed to treat 60-80 skins designed to produce leather meeting high standards for quality, safety and environmental protection. Considerably les chromium is discharged in effluents with this new process than in traditional methods. The economics and environmental benefits of this new technology are discussed.

Characterization of solid tanning salts manufactured from iron (III) sulphate and potassium acid tartrate / E. L. Talvani in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 78, N° 2 (03-04/1994)

Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Preparation and the characterization of solid tanning salts from iron (III) sulphate and potassium acid tartrate (cream of tartar) were performed. The iron (III) sumphate was obtained as a by-product of the processing of titaniferous iron ores from the Province of Buenos Aires. The manufacture started with physical upgrading of the ore and the concentrate thus obtained was then digested with sulphuric acid. At the end of the reaction iron (II) sulphate heptahydrate was separated, and the separated iron (II) was oxidised and cream of tartar was added to stabilize the iron (III). Solid tanning salts were obtained by spray drying. The storage and stability of the preparations were measured as a function of the principal physicochemical parameters. Finally, the suitability of the solid tanning salts for the tannage of goat skins was determined. The evaluation of the tanned leathers was performed by means of physico-mechanical tests and chemical analyses.

Strength of brazilian goatskin leathers in relation to skin and animal characteristics / Y. L. Wang in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 78, N° 2 (03-04/1994)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 78, N° 2 (03-04/1994) . - p. 55-60 Titre : Strength of brazilian goatskin leathers in relation to skin and animal characteristics Type de document : texte imprimé Auteurs : Y. L. Wang, Auteur ; Geoffrey E. Attenburrow, Auteur Année de publication : 1994 Article en page(s) : p. 55-60 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : There are clearly advantages in being able to understand how the characteristics of an animal's raw skin relate to the physical properties of the leather produced from it For example, such knowledge will assist in the selection of those breeds which will yield the best leather for a given application. Although there have bee a number of studies relating animal and skin characteristics to leather properties for bovine leather research on this topic apears less well developed for goatskins and leather. This paper therefore details some recent work on Brazilian goat skins wich was concerned with the relationship between animal and skin characteristics and leather strength. Goatskins covering a range of breed, age and sex were obtained from the Sobral experimental station in Brazil. The skins were subjected to a variety of chemical, biochemical, biophysical and histological analyses including measurement of collagen content, fat content, amount of glycosaminoglycan, relaxation of shrinkage stress and assessment of compactness of fibre weave. The skins were all processed together into leather and strength was assessed via tensile testing, tear testing and lastometer test. In addition, the apparent density of the leather was also measured. Most of the skin and leather characteristics showed a well-defined trend with increasing animal age. Glycosaminoglycan content and relaxation of shrinkage tension decreased rapidly up to the age of ten months thereafter more slowly. Collagen content increased more slowly up to age 20 months and thereafter levelled off. The weave of collagen fibre bundles became more compact with age. The strength of the leathers was strongly associated with their apparent density which in turn could be related to the compactness of fibre bundle weave in the skin. Although animal age appeared to be the dominant factor, breed influences could also be discerned. Thus the anglo-nubiana breed gave a lower strength leather than the general trend would suggest : this was ascribed to the greated fat content of its skin. It is concluded that assessments of goatskin characteristics can be directly related to leather strength. Such information is of considerable value in assessing which breeds are of most potential for leather production.
