Pollution -- Lutte contreIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The traditional method for bovine hide preservation requires approximately 40-50% sodium chloride on raw hide weight or 95% saturated brine solution in case of wet salting. This salt resides in wastewater after the soaking process and generates a huge environmental pollution in the form of total dissolved solids (TDS) and chlorides (Cl-) during leather processing. The current research has developed antiseptic based hide curing formulation using 45% saturated brine solution which reduces 50% salt usage in compare to traditional method. The newly developed formulations have been found more effective in limiting microbial growth on cured hide than the conventional method preserving the bovine hide for more than 30 days. In this study, post-leather analysis e.g. grain pattern, scanning electron microscopic images, mechanical properties and organoleptic evaluation reveal that the crust leather produced from alternatively cured hides are comparable to the control obtained from traditionally preserved hide. The efficacy of the alternative system is also assessed by monitoring the environmental impacts caused by the leather processing effluents on the basis of TDS and chloride content, total solids (TS), total aerobic bacterial counts in soaking liquor, Bio-Chemical oxygen demand (BOD) and Chemical oxygen demand (COD). The environmental advantages of the alternative hide curing method are determined particularly by 50% reduction of TDS and chloride content. Therefore, this new method is feasible and industrially preferable to the traditional hide curing process.

Titre : Preservation of cattle hides with potassium chloride Type de document : texte imprimé Auteurs : David G. Bailey, Auteur Année de publication : 1995 Article en page(s) : p. 13-21 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Research was conducted to evaluate the effectiveness of Potassium chloride(KCl) as an alternative to sodium chloride(NaCl)for the preservation of cattle hides. The incentive for this research is that concentrated KCl solutions do not cause the environmental problems that are associared with satured brine. Excess KCl brine from a curing raceway can be applied directly to the soil as a fertilizer providing potassium, a necessary plant macro nutrient. While KCl is more expensive than salt on a pound for pound basis the savings in brine disposal is some situations will more than make up the difference.On a laboratory scale we have demonstrated that cattle hide samples soaked in concentrated solutions of KCl and drained of excess moisture appeared to be well preserved after six months. A matched side study of KCl cured hides vs. NaCl cured hides was conducted in which the sides were stored for forty days before tanning. No signifiant differences were observed in two different lines of leather manufactured from hides.

Traitement par irradiationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In an earlier paper it was demonstrated that electron beam irradiated fresh hide samples stored in a sealed container could be preserved for six months. In this work leather prepared from cattlehide samples preserved by electron beam irradiation was evaluated. Leather made from electron beam irradiation preserved cattlehides has a reduced tensile strength and ball burst compared to leather made from unirradiated hides but was comparable in subjective evaluations such as grain quality and break. It was established that the amount of irradiation required for effective preservation could be reduced by pretreatment of the hide with a bactericide. The results also suggest that the area yield of leather from irradiated hides is similar to the area yield of fresh hides. Note de contenu : - Sample preparation

Extraits de plantes:Extraits (pharmacie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Preservation of animal skin using common salt is widely followed globally and has been in vogue since time immemorial. Salt used for preservation is discharged along with the soak liquor and contributes to 70% of TDS load from leather manufacturing. As an attempt to reduce chloride and TDS, plant based preservation with Tamarindus indica was studied. Different concentrations of salt and Tamarind leaf extract were applied on freshly-flayed goatskins based on its green weight and compared with control (40% salt alone/kg of skin wt.). Sensory evaluation of the preserved skin was done every day (till 21st day) for smell, hair slip and putrefaction. The samples were collected on 1st, 2nd, 3rd, 71h, 14th and 21st day and tests such as moisture content, total nitrogen content, protein content, hydroxyproline content and microbial load for finding out the curing efficiency. Skin those were preserved for 21 days were processed into leather and the leather and properties were examined. The result showed that 15% salt with 15% Tamarindus indica and 10% salt with 15% Tamarindus indica (Test) showed good preservation systems. Note de contenu : - Skin - Plant extract

Titre : Preservation of hides with sulfite. I. Concentration and application effects on small-scale experiments with cattlehides Type de document : texte imprimé Auteurs : William J. Hopkins, Auteur ; David G. Bailey, Auteur Année de publication : 1975 Article en page(s) : p. 248-2260 Langues : Américain (ame) Catégories : Acétique, Acide L'acide acétique (du latin acetum) ou acide éthanoïque est un acide carboxylique de formule chimique : C2H4O2 ou CH3COOH.
L'acide acétique pur est aussi connu sous le nom d'acide acétique glacial. C'est un des plus simples des acides carboxyliques. Son acidité vient de sa capacité à perdre le proton de sa fonction carboxylique, le transformant ainsi en ion acétate CH3COO-. C'est un acide faible.
L'acide acétique pur est un liquide très faiblement conducteur, incolore, inflammable et hygroscopique. Il est naturellement présent dans le vinaigre, il lui donne son goût acide et son odeur piquante (détectable à partir de 1 ppm21).
C'est un antiseptique et un désinfectant.
L'acide acétique est corrosif et ses vapeurs sont irritantes pour le nez et les yeux.
Il doit être manipulé avec soin. Quoi qu'il n'ait pas été jugé cancérigène ou dangereux pour l'environnement, il peut causer des brûlures ainsi que des dommages permanents à la bouche, au nez, à la gorge et aux poumons. À certaines doses et en co-exposition chronique avec un produit cancérigène, son caractère irritant en fait un promoteur tumoral de tumeurs (bénignes et malignes)21. Ceci a été démontré expérimentalement chez le rat.

Sulfate de sodiumLe sulfate de sodium est un composé chimique courant formé d'un ion sulfate et de deux ions sodium. Lorsqu'il est anhydre, il prend l'apparence d'un solide cristallin blanc de formule chimique Na2SO4. La forme déca-hydratée, Na2SO4·10H2O, est connue sous le nom de sel de Glauber ou mirabilite. Parmi un grand nombre d'usages différents, les principales utilisations du sulfate de sodium concernent la fabrication des détergents et dans le procédé de Kraft de traitement de la pâte à papier. La moitié environ de la production mondiale provient de l'extraction de la forme naturelle décahydratée, et l'autre moitié de productions secondaires dans des procédés de l'industrie chimique.
sulfite de sodiumIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : This study examines the effects on the length of hide preservation of (a) sulfite concentration, (b) sodium bisulfate and acetic acid as acidulants, (c) sodium bisulfite alone, and (d) various methods of handling and storing the treated hide samples. Small-scale studies indi-cated that short-term (six days) preservation could be accomplished at concentrations of 0.25 percent sodium sulfite and that 0.5 percent sulfite in combination with one percent acetic acid resulted in long-term (30 days) preservation. The need to containerize the treated side was demonstrated. Sides that were preserved with sulfite, drained, and stored in closed containers for six days at ambient temperatures were made into acceptable leather. An estimated cost of materials for the sulfite preservation compared favorahly with the material costs for brine curing.
