Produits de conservation du cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Although tanning makes the collagen matrix resilient against microbial attack, the chemicals used in the finishing process are susceptible to microbes. Hence, it is imperative to develop a finishing process with inherent antimicrobial properties. Leathers with antimicrobial properties evoke a considerable array of interest in consumers. The present study aims to enhance the antimicrobial properties of the leather using copper nanoparticles in the finishing and retanning process. Copper nanoparticles have been synthesized by chemical reduction using copper sulphate pentahydrate as the precursor with dialdehyde starch and gallic acid. The prepared nanoparticles have been characterized using UV-Visible spectrometry, dynamic light scattering, scanning electron microscopy, transmission electron microscopy, and X-ray diffraction techniques. The prepared nanoparticles have been used in both retanning and finishing processes. The experimental leather retanned using copper nanoparticles possess good mechanical strength properties and color index value compare to the control. Nanoparticles are effective against both gram negative and positive bacterial organisms. The nanoparticles also inhibit the growth of common fungus, which can colonize on leather. Thus, the current study paves the way for a novel solution that is an alternative to biocides and antimicrobial chemicals and is more effective in inhibiting microbial growth.

Fluorure de silicium
FluoruresIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Protection against development of putrefaction during suspension drying of hides during the West African wet season was investigated. Hides were dipped for 60 min in a saturated solution of sodium silicofluoride or boric acid or sprayed with a 10% solution of Vantocil IB immediately after flaying and fleshing. Both boric acid and silicofluoride treatments gave effective protection without adverse effect on leather-making quailties of the treated stock. The Vantocil spray treatment gave a significant improvement in preservation compared to untrerated hides but was not as effective as the boric acid or silicofluoride dip treatments. At present the use of silicofluoride is promising as the most cost-effective treatment.

Cuirs et peaux -- SéchageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the tropical wet season, for example in West Africa, putrefaction of hides and skins during suspension drying is significant but may be reduced by pre-treatment of the raw stock with a bactericide. A suitable chemical must be cost-effective, have no adverse effects on leather-making qualities and acceptable with respect to health, safety and the environment. For application in less developed countries and small throughputs, a simple method of application with minimum expertise in process control is required. The chemical must remain effective during drying. The purpose of this paper is to review chemicals which have been used previously either as salt additives or for salt-free short-term preservation of hides and skins, with a view to potential application in suspension drying. Among inorganic chemicals, boric acid and sodium silicofluoride appear most promising and zinc compounds may have limited potential. Sulphites, chlorites, hypochlorites and sodium carbonate are less attractive. Among organic and proprietary chemicals, Vantocil IB presently offers most potential. Phenol and cresol type preservatives have several disadvantages, although sodium pentachlorophenate may have value as an auxiliary in spray treatment. Naphthalene and derivatives, quaternary ammonium compounds (benzlkonium chloride) and various proprietary chemicals of current interest for salt-free short-term preservation also have disadvantages. The use of antibiotics and medicinal compounds is discouraged. Note de contenu : - Factors in assessment of bactericides

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Titanium (Ti) and its alloys are used extensively in implants due to their excellent biocompatibility and mechanical properties. However, Ti-based implant materials have specific complications associated with their applications, such as the loosening of implanted host interface owing to unsatisfactory cell adhesion and the susceptibility of the implants to bacterial infections. Hence, a surface that displays selective biointeractivity, i.e., enhancing beneficial host cell responses but inhibiting pathogenic microbial adhesion, would be highly desirable. This study aims to confer long-lasting antibacterial properties and good biocompatibility on Ti via the microarc oxidation technique. The biocompatibility of the Ti surface was evaluated by cytotoxicity test, and the bacteriostasis rate was evaluated by antibacterial efficacy. The results showed that the implant surface might be nontoxic to cell and its long-lasting antibacterial properties could be significantly improved. These results indicate that such microarc oxidation coatings are expected to have good potential in transcutaneous implant applications.
