LipidesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : La présente étude a été mené dans plusieurs optiques :
- vérifier l'efficacité du dégraissage en fonction des principaux états de conservation des peaux,
- déterminer l'évolution de la fraction lipidique résiduelle et en déduire les altérations qu'elle peut éventuellement subir,
- déterminer à l'aide de cycles de vieillissement si, au stade du cuir fini, les matières grasses non extraites continuent à se dégrader et participent à la formation de repousses grasses.
Les résultats mettent entre autres évidence l'influence prépondérante des modes de conservation et montrent que, même avant stockage, les peaux contiennent souvent tous les éléments favorisant la repousse grasse.Note de contenu : - METHODES D'ANALYSE

Teinture -- DéfautsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Dissolved dyes were recommended for use in effect finishes for patent leather in Europe in the sixties. Solvent-soluble dyestuffs (vat dyes) were mainly used for this despite their very poor fastness to migration.
During the same period, dyestuffs dissolved in organic solvents (usually DMF) were used in aqueous finishes. This dyeing method came from USA. In the sixties, Dr. Luch and his colleagues developed a system of liquid dyestuffs wich were suitable for both aqueous and organic finishes. At the same time a dyeing technique was developed which was similar to the padding process commonly used to dyes textiles. The leather was dyed in a through-feed machine. Dissolved metal complex dyes with a low salt content, which produced lighfast dyed aniline leather, were used in this process. The problems of this type of dyeing were very obvious. It was virtually impossible to obtain fastness to migration and fastness to perspiration/water spotting at the same time.Note de contenu : - Liquid metal complex dyes

Titre : Liricure-powder biocide composition for hide and skin preservation Type de document : texte imprimé Auteurs : Alan E. Russell, Auteur ; R. Kohl, Auteur ; H. Tandt, Auteur Année de publication : 1997 Article en page(s) : p. 137-142 Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Environmental concerns, process efficiency and economy are interrelated factors driving technological innovation in the leather industry. In a water-scarce country like South Africa in particular, it has been necessary to explore alternative clean preservation options to conventional salt curing.
Introduction of antiseptic preservation (or "chemical curing") in the 1980s served to provide the industry with a short-term preservation option and reduced dependence on salt forlocal hide holding and transportation. Alternatives to this approach were the chilling of cattlehides (with or without biocide addition) or direct processing of green hides to wet-blue leather, wherever possible.
The need for a comparable "salt-free" preservation method for sheepskins has led to the investigation of direct application of powder preservative compositions to the flesh side of freshly-flayed skins. Undesirable wetting of the wool cover, inherent in other antiseptic methods, was thereby avoided. It avoided. It was found that substantial storage periods were possible by application of a range of antiseptic (organic/inorganic) powder extender mixtures uniforly distributed over the moist flesh surface (approx. 200 g per skin), followded by folding flesh-to-flesh to maintain close contact with the applied preservative composition. Storage/dosage studies at a controlled temperature (25°C) showed a progressive increase in storage time. Application of selected compositions in field storage trials on gloving skins yielded pickled pelt and crust leather quality comparable with normal production after 6 weeks ambient storage.
Extension of the application method to cattlehide necessitated an increase in the application dosage to physically cover the larger hide area (approx. 3 kg per hide) ; treated hides were "saddle-stacked" to maintain contact of the preservative composition with both sides of each hide.
A total of six production hide (winter/summer) storage/transportation trials has been completed using the LIRICURE method over sotrage periods ranging from 1 to 2.5 weeks. The resultant wet-blue and crust auto and shoe upper leather had properties and quality comparable with normal production. Examination of the salt (ash) and moisture contents in Liricure treated stock indicated that substantial reductions in salt usage (approximately ten-fold decrease) were achieved compared with conventional salt curing. The method has been registered as a joint (LIRI Technologies/Meat Board) South African Patent (February, 1995).
The enhanced preservative effect in the Liricure method is attributed to one or more of the following factors :
(a) Initial introduction of high antiseptic concentration in the surface moisture of the skin (or hide) in excess of minimum inhibitory requirements ;
(b) Partial reduction in natural skin moisture due to osmotic effects, thereby removing available water necessary for bacterial growth and development ;
(c) Reduction in water activity in residual skin moisture due to dissolution of solutes (antiseptic, salts), thereby further inhibiting bacterial growth ;
(d) Increase in skin stability in the presence of dissolved salts, rendering it resistant to bacterial enzyme action ;
(e) Shifts in skin surface pH on dissolution of solutes (whether acidic or alkaline) further inhibiting bacterial growth.En ligne : https://drive.google.com/file/d/1kLwssHFus1pjNEx_FSPVKEZCFh9KyXz5/view?usp=share [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8013
