Titre : Use of an elastomer formed in situ for softening leather Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; Paul L. Kronick, Auteur ; Susan K. Iandola, Auteur ; P. H. Cooke, Auteur Année de publication : 1994 Article en page(s) : p. 260-268 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Poly(vinyl oleate) was used as a model compound in a continuing study of polymeric fatliquoring agents. It was emulsion-polymerized in-situ in retanned, non-fatliquored blue stock. The products showed appreciable improvements in mechanical properties, including increased elongation at failure and increased energy to break with no loss in tensile strength. Lower levels of acoustic emission were observed in treated samples, indicating reduction in fiber adhesion. X-ray probe (EDX) microanalysis with the aid of osmium tetroxide was used to locate sites of unsaturation and polymerized vinyl oleate in the interior of the treated leather.

Travail de rivière (cuir)Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The tannery industry uses huge amounts of water and increasingly more energy. Any attempt to reduce this use would result in economic savings in the processing of hides. It can be seen in this paper that the use of new types of drums for processing leather, called Cangilones drums [cangilones = scoops/buckets], can result in important technical advantages for the tanneries as well as water and energy savings. The technical advantages are derived from the design of the drums. This design determines the physical movement of the load inside the drums. In the Cangilones drum, the movement of the hides is caused by gravitational forces and the float moves with the hides.
Consequently, the penetration of chemicals is greater and the wastewater is more highly exhausted. Less float is needed for processing the hides and water savings are thus obtained.Note de contenu : - Experimental details

Titre : Use of poly(vinyl stearate) for fatliquoring Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; L. L. Liao, Auteur ; M. Komanowsky, Auteur ; Paul L. Kronick, Auteur Année de publication : 1993 Article en page(s) : p. 353-357 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Vinyl stearate, a commercially available monomer, was used as a model compound for studying polymeric fatliquoring agents. It was readily polymerized in emulsion by free radical initiation in the presence of retanned, non-fatliquored blue stock. The product showed improvement in mechanical properties such as a 65% increase in elongation at failure and a 75% increase in energy to break with no loss in tensile strength. In addition, improved water repellency and resistance to water penetration were noted as the amount of vinyl stearate offered was increased.

Tannage Résumé : This study examined the characteristics and environmental load of sheep skins that had been treated with silk hydrolysate by two different methods : prior to tannage and after tannage. Silk hydrolysate was applied to the leathers before and after tanning in four different proportions. The chrome oxide content and shrinkage temperature, tensile strenght and tear load of the leathers increased as the proportion of silk hydrolysate increased, and the highest levels of chrome exhaustion in the tanning effluents were obtained at an application level of 5% on the basis of leather weight. In addition, silk hydrolysate was found to improve wastewater parameters such as chemical oxygen demand, total suspended solids, total dissolved solids, salinity and electrical conductivity.

Titre : Use of TOC as an alternative to COD for monitoring the biooxidation of tannery unhairing waste Type de document : texte imprimé Auteurs : J. E. Cooper, Auteur ; E. H. Bitcover, Auteur ; E. M. Filachione, Auteur ; J. W. Harlan, Auteur ; David G. Bailey, Auteur ; Stephen H. Feairheller, Auteur Année de publication : 1980 Article en page(s) : p. 331-339 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A test for chemical oxygen demand (COD), requiring approximately 4 hr, is commonly used to monitor the biooxidation of wastes. A test for total organic carbon (TOC), which requires only 3 to 5 min, was compared with the more time-consuming method to determine if it could be used to estimate the COD test and to monitor the biooxidation. Both TOC and COD were determined for various proteins and amino acids, and the results of the two methods correlated well. The biooxidation of tannery unhairing wastes, complex industrial wastes characterized by high solids content, was monitored by both TOC and COD tests. The results obtained indicate that the TOC test is an acceptable alternative to the COD test when the composition of the waste does not vary significantly with time. Note de contenu : - Apparatus
