Titre : Strategic technical process design and competitive advantage enhancement techniques Type de document : texte imprimé Auteurs : Rumon A. Hankey, Auteur Année de publication : 2001 Article en page(s) : p. 255-261 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the dynamic environment of a globalized economy, customer-focused organisations, which have successfully developed strategies of growth, high market-share and differentiation are in a position to compete profitably and grow stakeholder value. Delivering results within this type of business strategy for the Leather Industry requires an equivalent highly developed Technical Innovation and Production Control Strategy. International Organisations can become more profitable by having a solid foundation to strategic technical process design to obtain competitive advantage. Successful achievement of which allows businesses to adequately design and successfully implement robust processes to consistently deliver high-performance quality products, with fast response times, cost-effectively to meet their customers' needs.

The kangaroo leather haad higher strength retention for all splits in comparison with calf leather figures from the literature. It was concluded that higher strength splits could be expected in lightweight kangaroo leathers of similar substance to calf leather.

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.En ligne : https://drive.google.com/file/d/1CDPYc9jeGyTdGLAg8yaINQ4F8tZ_7D7B/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8388

Titre : Stress-relaxation behavior of leather Type de document : texte imprimé Auteurs : M. Komanowsky, Auteur ; P. H. Cooke, Auteur ; W. C. Damert, Auteur ; Paul L. Kronick, Auteur ; Michael D. Mcclintick, Auteur Année de publication : 1995 Article en page(s) : p. 243-256 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather exhibits a complicated mechanical behavior that can be best explained by using concepts of theoretical viscoelasticity. To permit a mathematical description of the time dependent properties of leather under different testing conditions, springs and dashpots are used. A six-element model comprised of three Maxwell units in parallel satisfactorily described stress-relaxation properties of leather. Scanning-electron micrographs reveal that fibers remain desegregated upon drying of leather in the presence of fatliquor, while stress-relaxation tests show that relaxation moduli and relaxation times decrease with increase in fatliquor content as well as with increase in temperature and moisture content. The results obtainable by the stress relation method should find application in process control, specification acceptance and service evaluation.

Titre : Stress-strain relationships in leather and the role of fibre structure Type de document : texte imprimé Auteurs : Alan E. Russell, Auteur Année de publication : 1988 Article en page(s) : p. 121-134 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The degree of correlation between various upperleather physical test parameters has been examined in a set of experimental leathers obtained from controlled growth/nutritional trials carried out on a specific crossbreed. Results indicated that various stress-stress, strain-strain and stress-strain parameters were interrelated to a significant extent and, hence, reflected the same basic properties of the leather fibre structure. Predictive value varied depending on the particular correlation. Slaughter age (mass) was the predominant biological factor affecting full-grain leather strength and extensibility in the experimental leathers. Strength and extensibility decreased in more vertical weave angle and increase in grain-to-corium (major) layer ratio. Significant correlation between key upper leather test parameters provides a basis for mutual adjustment of minimum performance guidelines to reconcile acceptance limits in related tests.
