EntérobactériacéesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The detailed examination of the Enterobacteriaceae on salted hides and skins offers important information to assess faecal con-tamination of salted hides and skins, its roles in hide spoilage, and efficiency of hide preservation. Hence, salted cattle hide and skin samples were obtained from different countries and examined. Total counts of Gram-negative bacteria on hide and skin samples, respectively, were 104-106 and 105-106 CFU/g; of Enterobacteriaceae 104-105 and 105-106 CFU/g; of proteolytic Enter-obacteriaceae 103-105 and 105-106 CFU/g; of lipolytic Enterobacteriaceae 102-105 and 104-105 CFU/g; and of each species be-longing to Enterobacteriaceae 102-105 and 103-105 CFU/g. Moisture contents of the hide (between 17% - 29%) and skin samples (between 18% - 39%) were low, and salt saturations of most hide and skin samples were fairly high (100%), but these microor-ganisms were isolated from the samples in high numbers. Although 16 bacterial species belonging to genera of Cedecea, Enterobacter, Escherichia, Ewingella, Klebsiella, Proteus, Raoultella, Serratia and Yersinia were isolated from the hide sam-ples, 16 bacterial species belonging to genera of Citrobacter, Enterobacter, Escherichia, Klebsiella, Proteus, Raoultella, Serra-tia and Yersinia were isolated from the skin samples. These species were identified using API® 20E Test Kits. Although Cede-cea lapagei, Serratia rubidaea and Yersinia enterocolitica were the most prevalent microorganisms on the hide samples, Esche-richia coli, Serratia rubidaea and Serratia plymuthica were the most prevalent bacterial isolates on the skins. The most com-mon bacterial species isolated from both hides and skins was Serratia rubidaea. The presence of the members of Enterobacteri-aceae on the hides and skin samples in high numbers was evidence of faecal contamination and inadequate preservation. Ac-cording to biochemical test results, isolates exhibited catabolic activity to break down carbohydrate, lipid and protein which may adversely affect leather quality. Hide and skin samples contain different species of Enterobacteriaceae which may cause deterioration of hides and skins; therefore, effective antibacterial applications should be applied to hides and skins to eradicate these microorganisms and prevent substantial economical losses in leather industry.

Cire d'abeilleLa cire d'abeille est la cire particulière, sécrétée par les abeilles à miel, qu'elles utilisent pour construire les rayons à miel.
Utilisation : La cire d'abeille (notamment celle des opercules) est récupérée par fusion par les apiculteurs, parfois au moyen d'un four solaire6. Pour l'apiculture, elle est confiée à un "gaufreur" qui va la transformer en feuilles pré-imprimées d'alvéoles, qui inviteront les abeilles de la ruche à reconstruire leurs rayons à l'intérieur de cadres mobiles.
La cire d'abeille est aussi utilisée par les industriels de la cosmétique pour les produits de beauté comme les crèmes, les lotions, les onguents et les rouges à lèvres.
Elle sert également à la fabrication de médicaments, des chandelles et parfois à l'imperméabilisation et traitement d'entretien de certains matériaux comme le bois, le cuir et même le métal. Elle est aussi autorisée comme additif alimentaire (numéro E901).
Elle a des propriétés hydrophobes et antibactériennes.
La cire d'abeille peut se conserver très longtemps. Sa transformation est simple, un procédé de chauffage et de filtrage suffit à préparer la cire, qui peut être vendue en petits morceaux sans protection particulières. La cire fond à 64 °C.

Liants
Lin et constituantsLe lin cultivé (Linum usitatissimum) est une plante annuelle de la famille des Linaceae cultivée principalement pour ses fibres, mais aussi pour ses graines oléagineuses. Les fibres du lin permettent de faire des cordes, du tissu (lin textile pour ses qualités anallergiques, isolantes et thermorégulateurs), ou plus récemment des charges isolantes pour des matériaux de construction. Les graines sont utilisées pour produire de l'huile de lin pour l'industrie de l'encre et de la peinture, pour la consommation humaine et animale, à cause de sa richesse en oméga 3.
Le lin est une des rares fibres textiles végétales européennes. Elle a comme caractéristiques la légereté, la rigidité et la résistance et comme particularité d'être une fibre longue (plusieurs dizaines de centimètres), par rapport aux fibres courtes (coton, chanvre) ou moyennes (laine).

Solidité de la couleurIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Protein based finishing on leather surface is generally done using casein-based formulation which forms a transparent and breathable film. Other naturally available options such as protein extracted from flax seeds exhibit versatile application in various fields. Thus in this work, the flax seed protein which is found to be 84%, along with bees wax emulsion is explored for the first time as an Eco benign binder and as an alternative for casein based finish. The binders play very important role in leather finishing as it helps in binding the various constituents of finishing such as pigments, wax, and additives to the leather matrix. The prepared Eco benign binder formed a continuous film on the surface of the leather and improved the of physical properties and crack resistance of the leather. The FTIR and particle size analysis were carried out for the characterization of the Eco benign binder. The experimental leathers were tested for tensile strength, elongation at break, lastometer test, colour fastness and cold crack tests. The results of the said tests were satisfied and on par with control leathers.

Elastine
Enzymes protéolytiquesUne enzyme protéolytique est une enzyme capable de couper une protéine en plusieurs fragments ou peptides. La trypsine, la papaïne, la pepsine, la chymotrypsine, la plasmine, la subtilisine... sont capables de couper une protéine, chaque enzyme étant spécifique de certains sites particuliers de cette protéine. C'est ainsi, par exemple, qu'une immunoglobuline G est découpée par la papaïne en un fragment Fc et deux fragments Fab, comme l'a montré Porter en 1959.

SurfactantsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Most proteases exhibit broad-spectrum activities to all of the protein components of skins, thus, the indiscriminate application of proteases will bring out undue and non-selective loss of skin structural proteins, especially collagen and elastin, and lead to loose and damaged grain. Finding the effective ways to control proteases’ activities against collagen and elastin in leather processes is very important. In this work, the influence of typical surfactants on the collagenolytic and elastinolytic activities of frequently used proteases was investigated, and the mechanism was also discussed. The results indicated that the nonionic surfactants had slight effects and anionic surfactants exhibited quite different behaviors on the collagenolytic and elastinolytic activities of selected proteases. Both collagenolytic and elastinolytic activities of trypsin preparations were obviously inhibited by all selected anionic surfactants, especially SDS and SDBS. For the bacteria proteases, their elastinolytic activities were significantly activated and their collagenolytic activities were inhibited to a variable extent by anionic surfactants. Tanners may effectively control the selective action of proteases to collagen and elastin to achieve different requirements through correctly utilizing surfactants.

Langues : Américain (ame) Catégories : Chlorophénols Un chlorophénol est un composé aromatique constitué d'un cycle benzénique substitué par un groupe hydroxyle (phénol) et par un ou plusieurs atomes de chlore (chlorobenzène).
Les chlorophénols sont produits par halogénation électrophile aromatique du phénol par le dichlore. Le groupe hydroxyle étant orienteur ortho-para (effet -I/+M), on obtient préférentiellement un mélange de 2-chlorophénol et de 4-chlorophénol, puis le 2,4-dichlorophénol et enfin le 2,4,6-trichlorophénol. La tétra- et pentachloration nécessitent la présence d'un catalyseur (AlCl3).
La plupart des chlorophénols sont solides à température ambiante ; ils ont un très fort goût et odeur "médical". Les chlorophénols sont couramment utilisés comme pesticides, herbicides et désinfectants.

Spectrométrie de masseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : An improved analytical method was built based on the conventional standard method ISO 17070-2015 for the determination of 19 chlorophenols in leather. This developed method involved ultrasonic assisted extraction using methanol containing formic acid, derivatization using acetic anhydride, solid-phase extraction (SPE) cleanup with silica-gel cartridge. Final analysis of the chlorophenols compounds was performed by Gas Chromatography - Mass Spectrometry (GC-MS). Optimum conditions for sample extraction, such as time, temperature and formic acid content in methanol were studied. Satisfactory recoveries in the range of 92-105% (RSD, 2.1-7.3%) for the targets were obtained, and detection limits were in the range of 0.09-0.15 mg/kg. The developed procedure was evaluated and compared with ISO 17070-2015 which uses steam distillation for sample extraction. The method was successfully applied to determine 19 chlorophenols in series of leather samples from different origin. This study demonstrated that the ultrasonic assisted extraction, followed by acetyl derivatization and silica-gel cleanup coupled with GC-MS, can be used as an alternative to ISO 17070-2015, for detecting chlorophenols in leather.

Titre : Influence of benzenecarboperoxoic acid on chamois leather process Type de document : texte imprimé Année de publication : 2020 Article en page(s) : p. Note générale : Bibliogr. Langues : Américain (ame) Catégories : Chamoisage Le chamoisage est une technique artisanale qui consiste à fabriquer un type de cuir très souple et de grande qualité, utilisé notamment dans la ganterie. L'atelier où se pratique cette activité est appelé une "chamoiserie", tandis que l'artisan dont c'est la spécialité est un "chamoiseur".
Ce cuir était autrefois fabriqué à partir de peaux de chamois (d'où l'origine du mois "chamoisage") traitées avec de l'huile de poisson, ce qui en faisait un produit rare et cher. Les artisans essayaient donc de fabriquer des cuirs aux qualités approchantes en utilisant la peau d'animaux d'élevage, un tel cuir est alors appelé "peau chamoisée".
Le chamoisage est désormais pratiqué sur les mêmes types de peaux que celles utilisées en mégisserie (agneau, chèvre, vachette, mouton…). Il met en œuvre les mêmes opérations que la mégisserie jusqu'à l'étape de "gonflement". Les peaux sont alors étendues et enduites avec de l'huile de poisson, puis frappées avec un fouloir pour faire pénétrer l'huile. Durant cette étape on expose régulièrement les peaux à l'air (on les "évente"), tout en ajoutant de l'huile.
La dernière opération du chamoisage est le "remaillage" qui consiste à faire "cotonner" la peau en arrachant sa "fleur" avec un couteau qui ne tranche pas.
Un sous-produit du chamoisage, le "dégras", est très recherché par les corroyeurs pour apprêter leurs cuirs.
Il existe une norme française AFNOR qui s'applique aux peaux chamoisées : NF G59-001 de janvier 1981, Cuirs et peaux - Peaux chamoisées - Présentation, dimensions et marquage.

Perbenzoïque, AcideL'acide perbenzoïque, ou acide peroxybenzoïque, est un composé chimique de formule C6H5COOOH. Il s'agit d'un peracide aromatique solide pouvant être obtenu par l'action du peroxyde d'hydrogène H2O2 sur l'acide benzoïque C6H5COOH, ou par traitement du peroxyde de benzoyle C6H5COO–OOCC6H5 par le méthanolate de sodium CH3ONa.
Il peut être employé, comme d'autres peracides, pour obtenir des époxydes, tels que l'oxyde de styrène C6H5–C2H3O à partir du styrène C6H5CH=CH2. (Wikipedia)
Porométrie
Température de retraitIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Stabilization of collagen against heat and enzyme is a key objective in the tanning process. In oil tanning, fatty acid present in the oil is oxidised mainly into aldehydes which interects with Ԑ amino groups of collagen to form stable covalent cross links. Conventionally, oil tanning consumes time from two to three weeks which primarily depends on the type of oil and oxidation method for completion of tanning. In the present research, the duration of oil oxidation is reduced using benzenecarboperoxoic acid (PBA). It has been observed that PBA significantly reduces oil tanning duration from two weeks to 4 days. Moreover, the water absorption capacity of experimental leather has also increased by approximately 48% (1% PBA) compared to control leather. Physical strength properties such as tensile and percentage elongation values have also found to meet the standard norms. In addition to this organoleptic properties are also on par with control leather. The present study focus on the accelaration of chamois process for making leather, using PBA as an oxidising agent.
