Tannage combinéLe tannage combiné se dit des tannages qui allient deux familles ou genre de tannage pour obtenir un résultat additionnant les qualités complémentaires des tannins mis en Å“uvre par exemple Chrome-Végétal ou Chrome-SynthétiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In order to reduce the disadvantages of chrome tannage, chrome-free tannage was developped by many technologists and tanneries. However, because of the structures and charge of the tanning materials in the chrome-free tannage, the absorption rate of the chrome-free leather for anionic dyestuffs, re-tanning agents and fatliquors is lower than that of the chrome-tanned leather. Therefore, in order to improve the absorptivity of the chrome-free leather for these products, an amphoteric polymer auxiliary agent was synthesized with methyl-acrylic acid, sodium methylallyl sulfonate and dimethyl diallyl ammonium chloride (DMDAAC) by free radical copolymerization using ammonium persulfate at 80°C for 3 hours. The molar ratio of methyl-acrylic acid, sodium methylallyl sulfonate and dimethyl diallyl ammonium chloride was confirmed to be 1.0/0.3/ 1.0. The structure of the amphoteric polymer auxiliary agent was characterized by FTIR, H-NMR, C-NMR. The charge and properties of the solution of the amphoteric polymer auxiliary agent were characterised. Applied results of the amphoteric polymer auxiliary on the absorption of chrome-free leather for dyestuff and fatliquor, show that it has strong auxiliary absorptive capacity and the absorptive rate of dyestuff and fatliquor is more than 96%.

Tannage Résumé : Amino resins used in the leather retanning process are condensation products of formaldehyde which makes such resins objectionable due to environmental hazards. Due to the carcinogenic effects of formaldehyde, there is a growing demand to produce formaldehyde-free leather. This work involves the synthesis of formaldehyde free melamine resins for producing environment friendly leather with improved retanning properties and thermal stability. A series of resins was produced by condensation of glyoxal and melamine at varied mole ratios. Stability and water solubility was achieved by sulfonation with aniline 2,5 disulfonic acid at varied degrees of sulfonation. Resins were evaluated to measure the viscosity trends in series.
Synthesised resins were studied for their comparative retanning properties in comparison with a commercial melamine resin as control. Mechanical properties like tensile strengths tear strengths, and elongation at break were measured and found to be improved. Similarly, the organoleptic properties were also evaluated and found to be better than for the control. Retanned pieces of leather were examined by SEM and tested for free formaldehyde content. The optimal resin was subjected to analysis by FTIR, TGA and molecular weight determination. Effluents collected from retanning baths were tested for pollution load efficiency. The results of the study confirmed that the prepared resins were supportive in producing formaldehyde-free leather with improved mechanical and organoleptic properties. The thermal stability of the resulting resins and pollution load efficiency was also found to be improved.Note de contenu : - EXPERIMENTAL PROCEDURE : Chemicals and apparatus - Preparation of aniline 2,5 disulfonic acid modified melamine glyoxal resins

ThermogravimétrieIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In this work a novel and eco-friendly retanning agent was developed to eliminate the potential risk of formaldehyde occurrence in leather along with improving the characteristics of leather. A series of sulfanilic acid modified melamine-glutaraldehyde resins were produced at varied mole ratios of melamine, glutaraldehyde and sulfanilic acid. The glutaraldehyde to melamine mole ratio (GL/M) was varied from 2 to 6 whereas the sulfanilic acid to melamine mole ratio (SNA/M) was varied from 0.5 to 3. The viscosity trend of resins in the series was studied.
Synthesised resins were used in retanning leather in comparison with a melamine-formaldehyde resin as a control. Retanned pieces of leather were evaluated for their mechanical properties and organoleptic properties. Samples of leather retanned with the optimal resin were also analysed for comparative free formaldehyde determination. Scanning electron microscopy was performed to study the morphology of grain surface and fibre structure of resulting leather. Effluent received from retanning process was analysed for pollution load estimation. The optimum resin was subjected to determination of its molecular weight, to thermo gravimetric analysis and FTIR. It was obvious from the results of this study that the optimal resin produced a leather with improved mechanical and organoleptic properties in comparison with the control.
Estimation of formaldehyde content in leather proved the complete elimination of free formaldehyde in leather whereas the level in control leather was 152mg/kg. Results from the pollution load study of waste water confirmed an improvement in efficiency of COD, TDS, TSS and formaldehyde by 13.40%, 9.71%, 8.82% and 100% respectively. SEM monographs of grain surface and collagen fibres showed better filling, distribution and reactivity of the optimal resin. Thermo gravimetric analysis proved the increase in thermal stability of developed resin by 16.3% as compared to control. The eco-friendly condensation polymer produced in this work was considered suitable for making formaldehyde-free leather with improved retanning properties, thermal stability and pollution load.Note de contenu : - EXPERIMENTAL PROCEDURE : Chemicals and apparatus - Preparation of sulfanilic acid modified melamine-glutaraldehyde resins (MGLSNA)

Stabilité thermiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Formaldehyde has many applications in the chemical industry including synthesis of amino resins which are used in leather processing. After application in leather, these resins are hydrolyzed under certain conditions to release free formaldehyde which has high environmental concerns due to its proven carcinogenic effects. The objective of this work is to develop a formaldehyde free melamine-based resin to produce green leather with improved retanning properties and thermal stability. The optimum melamine resin was synthesized by condensing melamine with glyoxal instead of formaldehyde. Further, the water solubility and improved thermal stability of synthesized melamine resins were achieved by introduction of sulfanilic acid in resin structure. Synthesized resin was used in leather retanning in comparison with commercially available melamine resin as a control. Both leathers were tested for mechanical properties, organoleptic properties, grain surface and fiber structure analysis. Comparative free formaldehyde content was measured in resultant leathers. Effluents of retanning baths were comparatively analyzed. Optimum resin was also characterized by thermo gravimetric analysis and FTIR. The results of this study showed that the experimental resin has imparted significant improvement in mechanical and organoleptic properties of leather as compared to the control resin. Analysis of free formaldehyde content confirmed the absence of free formaldehyde in leather treated with optimum resin while 141 mg/kg formaldehyde was detected in leather treated with control resin. Free formaldehyde was also absent in effluent of experimental resin while 305 mg/kg formaldehyde was detected in effluent of control resin. Moreover, percentage efficiency in COD, TDS and TSS load of effluent was observed as 9.62, 7.2 and 6.31 respectively. Resultant leather was free from formaldehyde making it safe for human along with reduction in pollution load of tannery.

RhéologieIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Amino resins have found important uses in leather manufacturing due to their selective filling properties. Conventional amino resins are produced from formaldehyde and result in an increase of formaldehyde content in finished leather greater than the permitted limits. Due to strict legislations and restrictions regarding formaldehyde contents in leather goods there is a growing demand to produce formaldehyde-free leather. In this study formaldehyde-free resins with improved thermal stabilities were prepared using glyoxal as condensing agent and orthanilic acid (o-amino-benzene sulphonic acid) as a sulfonating agent.
The glyoxal to melamine ratio (G/M) was varied from 2-6 and orthanilic acid to melamine ratio (ONA/M) was varied from 0.5-3 to produce aqueous solutions of the melamine resins. The viscosity trend in the series of resins was observed by varying the degree of sulfonation and varying the glyoxal/melamine ratio. Progress of reaction was monitored by FTIR spectrum through functional group region.
Newly synthesised melamine resins (MGONA) were comparatively applied on leather as a retanning agent against a conventional melamine-formaldehyde resin and further evaluated for tear strength, tensile strength and elongation at break. The leather retanned with the optimal resin was further assessed for organoleptic properties and SEM analysis. The thermal stability of the optimised resin was also evaluated comparatively against a conventional resin. The optimised polymeric resin was free from formaldehyde plus having better retanning properties and improved thermal stability.Note de contenu : - EXPERIMENTAL PROCEDURE : Chemicals and apparatus - Synthesis of glyoxylated melamine resins using orthanilc acid as sulfonating agent
