Tannage Résumé : Montmorillonite (MMT) has been modified with a long chain quaternary ammonium salt through a cation exchange reaction. The extent of the exchange was characterised by XRD (X-ray Diffraction), FT-IR (Fourier Transform Infrared Spectroscopy) and by the determination of CEC (Cation Exchange Capacity).The results prove that alkylammonium ions have taken the place of Na+ ions in Na+ - Montmorillonite (Na-MMT) and that the inter-laminar distance has been enlarged.
The possibility of using Na-MMT and organic-montmorillonite (O-MMT) in the treatment of wastewater from tanneries by utilizing their adsorption properties has been studied. The result shows that Na-MMT and O-MMT can absorb fatliquors to a certain extent.
A series of tanning experiments have been carried out to compare the tanning properties of Na-MMT, O-MMT and O-MMT/Cr3+. The results suggest that Na-MMT and O-MMT have some tanning capability, and that the composite O-MMT/Cr3+ with a very low content of Cr3+ can produce leather of light colour with a shrinkage temperature above 90oC.Note de contenu : - EXPERIMENTAL PROCEDURE :

Tannage Résumé : r-Methacryloxy propyltrimethoxysilane (MPTMS) was used as a coupling agent to introduce vinyl groups onto the surface of nano SiO2. A nanocomposite of MPNS/SMA was prepared by the polymerization of methacryloxypropyl nano SiO2 (MPNS), styrene (ST) and maleic anhydride (MA) with benzoyl peroxide (BPO)as initiator in toluene. The structure of the MPNS/SMA nanocomposite was characterized by FT-IR (Fourier Transform Infrared Spectroscopy) and TEM (Transmission Electron Microscope).
A series of tanning experiments have been carried out to compare the tanning and retanning properties of MPNS/SMA and styrene-maleic anhydride copolymer (SMA). The results show that MPNS/SMA has good tanning capability, and that leather treated with the MPNS/SMA nanocomposite is of good quality.Note de contenu : - EXPERIMENTAL PROCEDURES : Chemicals and instrumentation - Preparation of MPNS/SMA nanocomposite

Titre : The preservation of animal hides and skins with potassium chloride Type de document : texte imprimé Auteurs : David G. Bailey, Auteur ; Joseph A. Gosselin, Auteur Année de publication : 1996 Article en page(s) : p. 317-333 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The results of the research reported in this document support the hypothesis that potassium chloride can successfully replace sodium chloride for the preservation of animal hides and skins. The use of either of these salts results in a stable hide or skin that can be converted into leather many months after curing. They both also produce a gallon of saturated salt solution from each cattle hide (or equivalent weight of skin) as a by-product of the preservation. In the case of sodium chloride this is a difficult and often expensive effluent to dispose of in an environmentally sound manner. The same by-product containing potassium chloride is a valuable and easily disposable fertilizer solution. While some minor differences were observed in the potassium chloride cured hides during the tanning process, these differences did not appear to have any negative effect on the final product.

Stabilisants (chimie)Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Collagen, a unique connective tissue protein finds extensive application as biomaterial in wound healing, as drug carrier, cosmetics, etc. A work has been undertaken to study the stabilization of collagen using di and trihydric phenols -oxazolidine E Tanning Matrices. Resorcinol-oxazolidine E Tanning Matrix treated collagen has been found to be more stable than that of sequential combination tannages with the same materials. The study has demonstrated that oxazolidine E underwent ring opening to form the N-methylol intermediate and reacted with the hydrogen bonds of resorcinol to forme the Tanning Matrix. The Tanning Matrix then penetrated into the collagen fibres and by aggregation prevented the denaturation of collagen fibres with heating. The next reaction is the involvement of hydrogen bonds and hydrophotic interactions, and the aldehyde groups of oxazolidine E in reaction with basic amino acid side chains of collagen as the major force involved in the stabilization of collagen. In this way, a multiple point combination tanning occurs with the Tanning Matrix creating a high level stabilization of collagen and high hydrothermal stability.
