Titre : A model for the internal structure of hot pressed leather Type de document : texte imprimé Auteurs : A. Wyler, Auteur ; R. T. Markus, Auteur ; B. de Castro Année de publication : 1991 Article en page(s) : p. 52-55 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : By injecting scrap of mixed tannage skin or hide, previously reduced to fibres, to pressure and heat the internal structure of this raw material changes markedly going through well definable, consecutive phases. In this article the specified phases are described. By means of a simplifying model several unexpected phenomena that were observed with a Scanning Electron Microscope (SEM) are explained.

Titre : Model of the helical portion of a type I collagen microfibril Type de document : texte imprimé Auteurs : Eleanor M. Brown, Auteur ; Gregory King, Auteur ; James M. Chen, Auteur Année de publication : 1997 Article en page(s) : p. 1-7 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Collagen model - Collagens are an ubiquitous family of extracellular proetins in the animal world. Fibril-forming collagen in the animal world. Fibril-forming collagens are the major structural proteins. In addition to their biological function, collagens provide molecular frameworks that are utilized in the medical, food biological and technological, is a consequence of the basic structure of a protein. Computerized molecular modeling has been developed into a useful tool for visualizing structure-function relationships in proteins. The unique supramolecular characteristics of collagen have made it a suitable subject for model builders over more than thirty years. The bovine type I collagen microfibril model developed at ERRC now consists of 15 polypeptide chains of 315 amino acid residues each. This model is large enough to allow a comparison of its gross structurla features with the banding patterns obtained by electron microscopy. Measurable distances pertaining to the helix, triple helix, and microfibril are within experimetnal error of recently reported physical data on dried collagen samples. Two segments of the microfibril model, one rich in hydrophobic residues and the other rich in hydrophilic residues were examined in detail. The conformation of the hydrophobic segment more nearly matched the definitionb of collagen helix (57 %) than did the conformation of the hydrophilic segment (38 %). The model is potentially useful for studying mechanisms of both inter- and intra-microfibril crosslinking as well as for predicting the efficacy of specific modifications to the molecule or potential crosslinking agents.

Filtration
Modèles mathématiquesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A study on deformation and filtration properties of a leather semi-finished product after chrome tanning are presented. The analytical dependences of compressive load on compressive (recovery) strain and moisture content of a leather semi-finished product are obtained. The empirical dependences of hydraulic gradient on filtration rates are determined for various compression ratios of the leather semi-finished product. It was revealed that with an increase in compressive load and moisture content of the leather semi-finished product, the compressive deformation increases. The shoulder section is subject to the greatest deformation, then the belly section and the least deformation is observed in the butt section. A linear relationship has been established between the hydraulic gradient and the rate of moisture filtration through the leather semi-finished product in the directions perpendicular and parallel to its surface.

Entreposage frigorifiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Salt Curing is a method that is widely used for the preservation of raw hides and skins worldwide and this leads to high salinity in tannery effluents. The treatment of such highly saline stream poses serious challenges, as pollution control norms for salinity are quite stringent in many countries including India. Chilling has been proven a most efficient method both in terms of cost and preservation efficacy for short-term storage but adoption in decentralized raw material collection systems prevailing in many developing and underdeveloped countries is a major challenge. In the present techno-management study, an attempt has been made to model a strategic supply chain network for collection and chilling of raw hides and skins suitable for such decentralized situations. Tamil Nadu state in India has been chosen for the pilot project as it contributes close to 50% of the tanning activity in India. Eight clusters have been formed by grouping the districts of Tamil Nadu based on the geographical location. The optimized location for the chiller in each cluster was found using gravity location model and the feasibility of transporting the raw hides and skins from slaughterhouse to chiller has been studied.

Titre : Modeling wet processing systems and technologies Type de document : texte imprimé Auteurs : James N. Trapp, Auteur ; David G. Bailey, Auteur Année de publication : 1982 Article en page(s) : p. 120-136 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : A computerized model has been developed to provide a flzxible tool for conducting economic feasibility studies and budgeting analyses of alternative wet processing systems. The model is designed either to use standard technologies as "default" parameters or to accept any number of subsitutes for the defaults, so that the model can be readily "customized" to consider many alternative systems and new technologies. Output of the model includes a detailed listing of the specified or estimated costs for building, land, equipment, labor, chemical, maintenance, utility, tax, insurance, and depreciation by individual process steps and in total. Estimates of byproduct values and cost per hide and per square foot of product made are also generated. Note de contenu : - MODEL OVERVIEW
