Stabilité thermiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The influences of drying methods on the thermal stability of leather were investigated. The results show that drying methods have an obvious effect on the water content and hydrogen bonds between collagen fibres. The water content of leather after freeze drying is less than that after air drying. The collagen fibres after air drying combine more tightly than after freeze drying. Concerning stronger hydrogen bonds between collagen fibres, the thermal stability of air-dried leather is better than that of freeze-dried leather.

Titre : Infrared drying : A leather finishing application Type de document : texte imprimé Auteurs : S. Jöns, Auteur ; F. Taracena-Sanz, Auteur ; R. Zitzumbo-Guzman, Auteur Année de publication : 2006 Article en page(s) : p. 105-111 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In leather finishing, alternative technologies such as infrared radiation can provide fast and efficient heat transfer for drying water-based films compared to conventional convection processes. In this investigation, an infrared dryer was designed and parameters such as heater distance to substrate, number and spacing of heaters, and leather transport speed were evaluated by using response surface methodology. From an experimental array, it was found that heater spacing is not statistically significant. However, other variables can be manipulated to improve overall dryer performance. A statistical model predicting the film drying in the infrared dryer was derived which can be used to choose suitable operating conditions for a particular finishing formulation. Furthermore, if the equipment is properly tuned, IR radiation can reduce both dryer length and residence time of the substrate during the drying process.

Titre : Inhibiting lipolytic haloarchaeal damage on brine cured hide with halocin producer strains Type de document : texte imprimé Auteurs : Meral Birbir, Auteur ; S. Erylmaz, Auteur Année de publication : 2007 Article en page(s) : p. 69-72 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Bactériocines Les bactériocines sont une famille de peptides ou protéines synthétisés naturellement par certaines bactéries. Une bactériocine consiste généralement en un composé protéique de 20 à 60 acides aminés.
Les bactériocines ne sont pas des antibiotiques mais elles possèdent des propriétés antibiotiques :
- Elles peuvent être bactériocides, c'est-à -dire éliminer certains micro-organismes.
- Elles peuvent être bactériostatiques, c'est-à -dire inhiber la croissance de certains micro-organismes.

LipasesLes lipases sont des enzymes hydrosolubles capables d'effectuer l'hydrolyse de fonctions esters et sont spécialisées dans la transformation de triglycéride en glycérol et en acides gras (lipolyse). À ce titre, elles constituent une sous-classe des estérases.
LipolyseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The Kaldırım and Kayacık Salterns of Tuz Lake in Central Anatolia are the main salt sources of Turkey. 55% of the salt requirements of Turkey is supplied from these salterns. 492 000 and 620 000 tons of salt were produced from Kaldırım and Kayacık Salterns in 2004, respectively. Crude salt extracted from these salt sources is commonly used in hide preservation. Lipolytic extremely halophilic Archaea found in the salt may reduce hide quality. Therefore, a microbial survey was conducted to examine lipolytic activities of the strains isolated from Kaldırım and Kayacık Salterns and determine whether or not halocins which were produced by the strains of Kaldırım and Kayacık Salterns may be used to inhibit lipolytic haloarchaeal strains in brine solutions. The levels of lipase producer strains in the both salterns was found to be almost similar. 39% of Kaldırım Saltern’s strains and 43% of Kayacık Saltern’s strains produced lipase. 89% of Kaldırım Saltern’s strains and 29% of Kayacık Saltern’s strains produced halocins effective against each other. It was found that lipase negative halocin producers of both Kaldırım and Kayacık Salterns were able to inhibit lipase positive strains in these salterns.
Hence, it is recommended that lipase negative halocin producers or their halocin extracts may be used in preventing the haloarchaeal deterioration that can occur during brine curing of hides when using crude salt from whatever source.Note de contenu : - Growth conditions of extremely halophilic strains

Système pileuxIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In consideration of the fact that the hydrolysate of hair contains antioxidant and free radical scavenging groups, the inhibitory effect of protein filling agent prepared from bovine hair (HPFA) on the oxidation of Cr(III) was investigated. The results demonstrated that HPFA possessed remarkable reducing ability to transfer Cr(VI) to Cr(III) in solution when pH was lower than 6.0. The reduction reaction was enhanced with rise of temperature, extension of reaction time and increase of HPFA dosage. Meanwhile, the HPFA also presented a high activity to inhibit the oxidation of Cr(III) in chrome liquor in the presence of unsaturated fish oil fatliquor. More interestingly, the HPFA achieved satisfactory inhibitory effect on Cr(III) oxidation in leather in the temperature range from 20oC to 100oC. Its inhibitory activity was much higher than that of commercial protein filling agent made from collagen hydrolysate. All the results suggested that bovine hair could be used as a potential resource for preparing protein filling agent with both filling and Cr(III) oxidation inhibiting properties.
