PailleIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Modified corn straw, MCS, was prepared by pretreatment and esterification modification technology. The optimisation and mechanism of Cr(VI) adsorption performance was critically investigated via orthogonal experimental design and single-factor comparison experiments. Experimental results indicated that the MCS dosage and pH value had the greatest effect on the Cr(VI) adsorption process. Moreover, the Cr(VI) adsorption rate (CrAR) and maximum adsorption capacity (CrAC) were 96.8 % and 121mg/g respectively under the optimal condition (MCS dosage : 0.04g, adsorption time: 45 minutes, pH3, adsorption temperature: 40°C, Cr(VI) initial concentration : 10mg/L), which was an increase of 10.3 times compared to unmodified corn straw. FTIR analysis testified that carboxyl and ester groups were introduced into the MCS. Meanwhile, it turned out that the cellulose structure ctf MCS was found to be more orderly by SEM analysis than that of CS. The MCS might show great potentiel for application in the adsorption of Cr(VI) in tannery wastewater as a new type of biosorbent.

TomographieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this work, a novel cationic fatliquoring agent YI-1 was prepared by two steps. Firstly, a cationic emulsifier YW based on fatty acid triethanolamine ester was synthesized by using stearic acid, triethanolamine and benzyl chloride. Then, YH was obtained by mixing a certain amount of YW, non-ionic surfactant and neutral oil. The composition of YH was optimized by its application behaviour as a fatliquor. The structure of YW was characterised by infrared spectroscopy and H-NMR. The surface tension of YW aqueous solution was determined by using a surface tension meter. The stability, particle size and zeta potential of YH were studied. The results show that YH exhibits high centrifugal stability and electrolyte resistance with an average particle size of 24.44nm and zeta potential of 60.8mV at pl-14.5. The leather samples treated by YH show high softness, tensile strength and tear strength. When YH was used as a dye-fixing agent, it could promote the absorption and fixation of anionic dyestuff, and improve the dry/wet fastness of leather and the colour fastness of washing.

The isoelectric point, functional groups and morphology were investigated. Sorbent surface and chemical composition were characterised using scanning electron microscopy (SEM) and anergy dispersive X-ray spectroscopy (EDS). The functional group an CHW was investigated using Fourier transform infra-red spectroscopy (FTIR). The specific surface area and pore size distribution were determined by analyzes of BET/BJI-I which showed values considered low when compared to commercial activated cardon, through using SEM, EDS and FTIR we observed the presence of the dye in the adsorbent tested. The level of dye removal. was 70.82% (pH3.0) with maximum amounts of AB-161 dye adsorbed of 7.08mg.g-1. The obtained results offer a promising use for CHW as an efficient eco-friendly sorbent for the treatment of Ieather wastewater containing dyes.

Résistance au rayonnement ultravioletIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Although the research of leather chemicals has experienced considerable advances, it remains imperative and challenging to develop functional ones ; especially functionalized fatliquors or retanning agents. In consideration with the unique structure and properties, graphene oxide (GO) has been reported as a potential alternative to ameliorate the performance of leather. However, one of the intractable handicaps is how to make graphene penetrate evenly and react with collagen fibers. Here, we demonstrate a method for preparing graphene-based polymeric fatliquor (PFGO) via an amidation reaction between amino-groups of aminated graphene (AGO) and anhydride bonds of maleic anhydride-rapeseed ouf copolymer (MRO), which was synthesized by free radical copolymerization. The results show that the as-prepared fatliquor has good emulsion stability and can penetrate into the collagen fibers uniformly. Compared with the control sample without graphene, the antibacterial, electromagnetic shielding, flame retardant and UV resistance characteristics of the PFGO-treated leather were significantly improved. Overall, this effective yet promising paradigm may provide an achievable solution toward developing graphene-based polymer composites simultaneously with high physical property and high functional performance.

Titre : Preparation and characterization of alkali-soluble collagen from pigskin shavings Type de document : texte imprimé Auteurs : Shuai Shao, Auteur ; Min Zhang, Auteur ; Li Guoying, Auteur ; Wentao Liu, Auteur Année de publication : 2009 Article en page(s) : p. 344-351 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The leather industry discharges large quantities of solid wastes containing high-value native collagen. In this study, the pigskin shavings generated from the shaving of pelts which had been dehydrated with anhydrous sodium sulfate after deliming were pretreated to remove most of salt and fat. Then alkaline treatment method was used to extract collagen from the pigskin shavings. Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and circular dichroism (CD) spectra revealed that the alkali-soluble pigskin collagen (ASPC) retained the polypeptide chains and triple helix conformation. The amino acid profiles showed no major deviation from the characteristic collagen composition. Both of the denaturation temperature and the isoelectric point (pI) of ASPC were lower than those of pepsin-solubilized pigskin collagen (PSPC). Scanning electron microscopy showed that ASPC sponges had porous fibrillar network structures, and the pore sizes became larger with the decrease of collagen concentrations and as the pH of the collagen solution approached the pI of ASPC.
