Polyméthacrylate d'hydroxyéthyle-co-glycidyl méthacrylateIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hydrogel membranes can swell by a high proportion of their weight and have a large surface area, and are nowadays preferred in adsorption studies. In this work, p(HEMA-GMA) poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) spherical particulated hydrogel membrane (SPM) was produced by UV photopolymerization and the synthesized membrane was coupled with iminodiacetio acid (IDA) in order to bond the Cr(III) ions in the chrome tanning process effluent. Then p(HEMA-GMA)-IDA-Cr(III) SPM was used to remove Acid Black 210 dye from the dyeing process effluent. The membrane's chrome and dye adsorption capacities were determined using a UV/Vis Spectrophotometer at wavelengths of 601nm and 435nm respectively. After the membranes were used, the discharged tanning and dye process wastewaters were examined in order to see the differences in the wastewater in terms of COD, BOD, conductivity, pH, salinity, total dissolved solids, total suspended solids, potassium, total nitrogen and chromium content. The results showed that the metal-chelated p(HEMA-GMA)-IDA SPMs chelated chrome ions between 398.47 and 619.10mg/g, and the adsorbed Acid Black 210 dye molecules were between 0.76 and 1.87mg/g. In conclusion, p(HEMA-GMA)-1DA SPM is an effective sorbent system for removing Cr(III) ions and acid dye molecules from leather discharge waters. Note de contenu : - Characterisation of nano-PHEMA-AB

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The tanning characteristics of starch samples modified by different methods were investigated in our previous studies. In this study, utilization of modified starch in leather making as a retanning agent and its effect on dyeing process have been investigated. For this purpose, the molecular size of native corn starch was reduced by H2O2 oxidation and then carboxymethylated. A series of analyses (water solubility, degree of substitution, Fourier Transform Infrared Spectroscopy, Proton and Carbon Nuclear Magnetic Resonance Spectroscopy) were carried out for characterization. Then, carboxymethyl starches were used in retanning processes to be 3, 5 and 10% based on leather weight and the shrinkage temperatures and filling coefficients of the leathers were determined. Acid and metal complex dyestuffs were used in dyeing processes and the effect of carboxymethyl starch on dyeing was also investigated by examining dye consumption, dry and wet rubbing fastness and color of the leathers. From the results it was concluded that carboxymethyl starch showed a noticeable solo performance in terms of filling property and shrinking temperature without any considerable adverse effect on dyeing.

Résistance thermiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Certain species of filamentous fungi produce coloured substances as secondary metabolites, which can be used as dyes for industrial applications. These natural dyes can be environmentally friendly alternatives to synthetic dyes, since they are extracted from sustainable sources with high yields, can be produced independently of seasonal effects, and no hazardous chemicals are used while they are produced. In this study, a screening of natural colourants from filamentous fungi was carried out by cultivation in liquid medium and further the Monascus purpureus extract was applied to leather dyeing. The efficiency of the dyeing was quantified through the remaining dye concentration in the wastewater by UV-vis spectroscopy, and the quality parameters of the leather samples were evaluated by the change of colour when they were exposed to light and heat. The absorption of Monascus dye into the leather was 70.6 ± 2.7% when deacidification at pH5.0 was used. The dyed leather showed good penetration, colour homogeneity and heat fastness.
