Titre : Properties of collagen fibre in alkali and neutral salt solutions Type de document : texte imprimé Auteurs : Cheng Haiming, Auteur ; Chen Min, Auteur ; Li Zhiqiang, Auteur Année de publication : 2010 Article en page(s) : p. 65-69 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Alkali and neutral salt treatment, especially in liming is a key procedure in order to achieve a good quality of leather. However,liming creates sludge and wastewater which are difficult to process. To find a clean replacement for lime we need to know the properties of skin after alkali and neutral salt treatment. Collagen fibre and cattle hide are treated in alkali-neutral salt solutions. Collagen fibre will be swelled in alkali solutions in its axial directions. Sodium sulphate in high concentration depresses collagen fibre's swelling rate in alkali solutions, but sodium chloride does not have this effect. Hydrolyzates in alkali and neutral salt solutions are composed mostly of degraded collagen, having lost its characteristic collagen triple-helical conformation. Neutral salt may inhibit the cleavage of the salt bridges of collagen fibre in alkali solutions which will enhance its physical properties such as tensile strength.

Titre : Properties of collagens from pigskins of different ages Type de document : texte imprimé Auteurs : Keizo Wada, Auteur ; Kunio Shirai, Auteur ; Akira Kawamura, Auteur Année de publication : 1980 Article en page(s) : p. 90-99 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : When insoluble pigskin collagen was heated in a buffer solution at 60°C for one hour, about 60 percent of it was solubilized if the collagen was from 6-month-old skin, but only 20 percent if it was from 3-year-old skin. This indicates the strong effect of age. A similar effect was observed in the case of solubilization with 2 M CaCl2 at 20°C or 1 M urea at 45°C. When the two collagens where treated with pepsin, the influence of age on solubility almost disappeared and the amount solubilized increased to more than 80 percent for both. Disc electrophoresis of the digests indicated that they consisted mainly of alpha chains, although the content of components higher than beta was somewhat greater in the 3-year-old than in the 6-month-old collagen. The fraction of alpha 1 derivatives was separated into five peaks by CM-cellulose chromatography and disc electrophoresis.

Peau -- HistologieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The effect of fibre diameter, fibre length and primary follicle density on grain appearance of the skin of Australian bush goats was assessed. Good grain appearance was associated with a high density of primary follicles that produce, on these animals, medullated fibres of a relatively uniform diameter.
Fine grained skins are produced by goats of less than approximately 25 kg liveweight. The physical properties of the leather, as measured by tensile strength, elongation and lastometer, were evaluated and found to be comparable to commercial quality goatskins. Nutrition was found to have an effect on skin substance and density and indirectly, through skin area, on grain appearance.Note de contenu : - METHODS : Animal - Metrology - Sampling for physical testing

Coefficient de diffusionUn coefficient de diffusion est une grandeur caractéristique du phénomène de diffusion de la matière. Le coefficient de diffusion mesure le rapport entre le flux molaire dû à la diffusion moléculaire, et le gradient de concentration de l'espèce chimique considérée (ou, plus généralement, de la variable d'effort entraînant cette diffusion), comme formulé par la loi de Fick.

Titre : Proposed test for adhesion of finish to leather : Draft method IUF 470 (march 1988) Type de document : texte imprimé Année de publication : 1988 Article en page(s) : p. 218-222 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cuirs et peaux -- Finition Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : 1.1. By adhesion we mean the force required to pull the finish away from the underlying leather, the force being applied steadily at an angle of about 90° to a solid carrier to which the finish has been stuck.
1.2. Depending on the way the leather has been finished, the adhesion of the finish to the leather can be so low over the whole area or over only part of it be so low over the whole area or over only part of it that the finish separates from the leather during use. With finishes consisting of several layers, the separation may occur between the layers, for example, between the pigmented layer and the groung.
1.3. This method is valide for all finished leathers with a smooth surface, the surface of which can be made to adhere without penetration of the adhesive. Preliminary experiments may be necessary to clarify whether these conditions obtain.En ligne : https://drive.google.com/file/d/18kDUAHHfSW7ySs2c4UJ18EuX0E7klAY8/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9113
