Tannage végétalIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Recent fundamental studies in these laboratories have been concerned with the range of relatively weak, reversible interactions, generally ternied “polar” interactions, which occur between hide collagen and its aqueous environment. These studies have provided further insight into the factors governing this reactivity. The interaction has wide significance in determining solubilities and properties of solutions, the solution structure of proteins as well as the interaction of hide collagen with technological materials such as vegetable tannins, dyestuffs and water-proofing agents. Hence, greater understanding of the basic processes involved is a prerequisite for rationalisation and improvement in the technological operations of curing and tanning. In this review, the mechanism of polar interaction indicated in fundamental studies is outlined and some areas of practical application discussed, including the use of polar additives as penetration assistants in vegetable tannage and the application of polar molecules carrying longchain hydrocarbon structures in waterproofing treatments for leather.

Theory and practice of leather manufactureURLTheory and practice of modern chamois leather production / J. H. Sharphouse in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 69 (Année 1985)

Titre : Theory and practice of modern chamois leather production Type de document : texte imprimé Auteurs : J. H. Sharphouse, Auteur Année de publication : 1985 Article en page(s) : p. 29-43 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The bulk of chamois leather is used as wash leather for cleaning windows, car bodies and similar surfaces where its particular merit is its softness, high water absorbence and "wringability" ; some eight million skins are processed annually.
The traditional method ofmaking chamois leather was to impregnate the damp flesh splits of sheepskins with cod liver oil in fulling stocks and then hang them up in warm stoves to allow oxidation of the oil to occur, the products of which reaction had a tanning action. These two processes might be repeated two or three times until a satisfactory leathering was achieved.
Surplus oil was removed by hydraulic pressing (to yield a by-product known as Dégras or Moellon) followed by a final wash in warm alkaline water. The skins were then hung to dry and finished. The process is dirty and labour-intensive. For a production of 1000 skins per day, 75 mean hours were needed and 20 000 ft2 of warm stove area, with a high fire risk.
The modern system described herein and largely innovated by tha author as commercial process in Europe and the USA, loads the damp flesh splits into a large rotating drum along with the cod liver oil. Whilst this is rotating, a controlled blast of warm air is blown in, which effects some drying of the skins and suitable oxidation of the cod oil, so that complete tannage may be achieved in 12 h. Subsequently, surplus oil is removed by a solvent degreasing plant to yield a dry, tanned chamois leather.
The merits of this system are a reduction to nine man hours only, elimination of the warm stoves, a big improvement in cleanliness of working conditions, a yield of superior anhydrous Dégras, and the elimination of effluent problemsn incidental to the use of alkaline, aqueous wash liquors. The practical development of these systems was carried out by the author over a number of years and the back-up research performed under his guidance by a number of his students in the former Leather Department of the College of Technology, Northampton (now the Leathersellers' Centre, Nene College).Note de contenu : - The nature and characteristics of chamois leather.

PyrolyseLa pyrolyse est la décomposition ou thermolyse d'un composé organique par la chaleur pour obtenir d'autres produits (gaz et matière) qu'il ne contenait pas. L'opération est réalisée en l'absence d'oxygène ou en atmosphère pauvre en oxygène pour éviter l'oxydation et la combustion (L’opération ne produit donc pas de flamme). Il s'agit du premier stade de transformation thermique après la déshydratation.
Elle permet généralement d'obtenir un solide carboné, une huile et un gaz. Elle débute à un niveau de température relativement bas (à partir de 200 °C) et se poursuit jusqu'à 1 000 °C environ. Selon la température, la proportion des trois composés résultants est différente.
Spectrométrie de masse
ThermogravimétrieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather tanned with different agents was pyrolyzed in the presence of CoC12 and MnC12 catalysts. A bovine leather sample tanned with two inorganic tanning agents (chromium and titanium salts) and two organic tanning agents (glutaraldehyde and methylacrylic resin) has been used in this study. The samples were soaked in solutions of CoC12 or MnC12 of known concentration. The influence on decomposition temperature and the resultant pyrolysis compounds has been evaluated by using thermogravimetric analysis (TG/DTG) and flash pyrolysis (Py-GC/MS). A multivariate analysis has been applied to the pyrolysis products obtained confirming the effect of the catalyst treatment on leather, specifically on samples tanned with organic agents. According to the results, CoC12 (higher Lewis acidity) shows a greater influence than the MnC12 (lower Lewis acidity). The results indicate that the presence of chlorides affects the nature of the pyrolysis products, increasing the yield of the aromatic compounds in ail the samples, thus improving the added-value of the volatiles. These catalysts reduced slightly the decomposition temperature.
