Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The objective of this work was to ascertain the performance of extracted gelatin from dechromed leather shavings as a coating in the finishing of leather. Gelatin is a protein-ased material isolated from chrome-tanned collagenic wastes. A comparison between a commercial protein-based product, extracted gelatin and a mixture of extracted gelatin/glycerol was carried out. Based on the results obtained in previous studies, two fixing agents were used to fix the finishing : 5-ethyl-1-aza-3,7-dioxabicyclo[3,3]octane (oxazolidine II) and ethylene glycol diglycidyl ether (EGDE). The mixture gelatin/glycerol (using glycerol as a plasticiser) presented satisfactory results, compared with the commercial product, for the abrasion, gloss and flex resistance, although a poor performance under wet rub fastness (assessment of 1 on the grey scale (ISO 105-A02, A03) and adhesion tests were found due to the hygroscopic nature of glycerol. The formulation for potential further studies was the extracted gelatin fixed with EGDE which showed the best performance on dry rub fastness (4-5 on the grey scale) and finish adhesion, and a good performance on resistance to abrasion and to flex (low loss of finishing and no cracking observed). The results confirmed the optential for gelatin, obtained from chrome shavings, to be used as a leather finishing agent.

Colour changes during ageing of finished leather / H. Turner in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 76, N° 5 (09-10/1992)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 76, N° 5 (09-10/1992) . - p. 169-171 Titre : Colour changes during ageing of finished leather Type de document : texte imprimé Auteurs : H. Turner, Auteur ; D. Davighi, Auteur ; Geoffrey E. Attenburrow, Auteur Année de publication : 1992 Article en page(s) : p. 169-171 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather was dyed pink or beige using various dyestuff types and a range of fixing agents after whichit was base coated and either left without a topcoat or given a solvent based top coat or an aqueous based topcoat. This range of samples was then subjected to accelerated ageing and colour changes were monitored. In the case of the pink leather significant colour changes were observed. It was concluded that these changes were not due to dye migration from leather to coating as originally thought but were associated with the fatliquor used in the leathermaking process. The type of topcoat applied had a significant influence on the degree of colour change observed.

Tannage Résumé : We report the dynamic mechanical behaviour of leather within the temperature range - 100 to 300°C, where three major viscoelastic transitions were identified, termed α, β and γ. The β transition peak represents the glass transition temperature of the amorphous region of collagen molecules. It also demonstrates that tanning agents act as plasticisers and depress the glass transition temperature to a lower temperature. Thus, the tanning process itself may be viewed as a plasticisation of the collagen molecule : the tanning molecules interpose themselves between the collagen chains, thus reducing the forces holding the chains together. Different tanning agents show differing degrees of plasticisation.

Factors influencing the softness of brazilian goatskin leathers / Y. L. Wang in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 78, N° 3 (05-06/1994)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 78, N° 3 (05-06/1994) . - p. 85-87 Titre : Factors influencing the softness of brazilian goatskin leathers Type de document : texte imprimé Auteurs : Y.

Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The skins of a number of brazilian goats covering a range of breed, age and sex were subjected to chemical, physical and histological characterisation. Half of each skin was processed into leather and its softness assessed by hand and instrumentally using both the BLC softness gauge and a compression test. It was found that each measure of softness could be related to the apparent density of the leather which in turn was associated with both the compactness of fibre weave in the skin and the fat content of the skin.

Part 2 : The mechanism of the vegetable tannin-oxazolidine tannage Type de document : texte imprimé Auteurs : Bi Shi, Auteur ; Youjie He, Auteur ; Haojun Fan, Auteur ; Shaoyu Zeng, Auteur ; Anthony D. Covington, Auteur ; Geoffrey E. Attenburrow, Auteur Année de publication : 1999 Article en page(s) : p. 8-13 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Catechin was used as a model for condensed vegetable tanning, to elucidate the reaction between the flavonoid ring system and oxazolidines in the combination tannage. Using 1H-NMR, 13C-NMR and paper chromatography, it is shown that the crosslinking reaction occurs predominantly at the C-6 and C-8 of the phloroglucinol A ring of catechin. The crosslinker reacts at the C-5 of oxazolidine, by ring opening and reacting via the N-methylol intermediate.
