Modern researches in leather dyeing / Samir Dasgupta in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 60, N° 6 (11-12/1976)
[article]
Titre : Modern researches in leather dyeing Type de document : texte imprimé Auteurs : Samir Dasgupta, Auteur Année de publication : 1976 Article en page(s) : p. 163-168 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cuirs et peaux -- Teinture Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The colour of the leather is the most important factor for its acceptance to the customer. Leather has other important characteristics such as water vapour permeability which are difficult to demonstrate convincingly to the customer. Recent developments in dyeing have contributed considerably towards producing serviceable leather in anticipation of the changing demand of the customer. Constant efforts should be made in the future to develop dyes with improved fastness properties, in particular dry-cleaning and perspiration fastness. Developments in the manufacturing technique of leather with better hydrothermal resistance would contribute towards improvements in continuous through-put dyeing systems. All these would further improve the competitive position of leather against synthetic materials Note de contenu : - IMPROVEMENTS OF FASTNESS OF DYED LEATHER : Auxiliaries - Newer types of dyes - High temperature dyeing

Essais (technologie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In most works, selection of dyes for the dyeing of leather is based on long years of practical experience. Yet accelerating changes in fashion which involve changes in processing methods, particularly regarding retanning, fatliquoring, etc., as well as changes in countries of origin of skins, result in a change of behaviour of these leathers during dyeing. Frequently operational considerations prevent changes in substrate and in method of dyeing. Dyeing results can, however, be substantially improved by an optimum dye selection in accordance with recently established criteria. The dyeing behaviour of any dye on leather is influenced by many factors. In is difficult to create conditions that are exactly reproducible. Under the name of "Dermagen testing method" a process has been developed which is characterised by the mass-dyeing of a leather pulp made of shavings of a standard-tanned leather.i Depending on the standard depth2 figures are established for build-up power, the saturation limit as well as the affinity of a dye. On the basis of the numbers of affinity and the build-up power dues can be won about the behaviour of dye or combinations of dyes on leathers of varying pretreatment. Thus the selection of dyes on the basis of their dyeing behaviour is greatly simplified. Note de contenu : The dermagen testing method

Vitamine EIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Microbial colorants are becoming popular because they have the potential to overcome disadvantages of synthetic and natural dyes. However, for commercialization, their after dyeing characteristics especially light fastness needs to be improved preferably using natural agents to make the complete dyeing process eco-benign. Therefore, in this study, eco-friendly tannins and antioxidants were employed to improve the light fastness of wet blue goat nappa skin dyed with the colorant of Penicillium minioluteum. Their effect on color strength, fastness properties, and mechanical strength were also assessed. As a result, the only sample treated with tannic acid before dyeing showed moderate light fastness with improved perspiration, tear, and tensile strength. Further improvement in light fastness was recorded when tannic acid treated and dyed sample was padded with vitamin E - gum acacia emulsion (10% vitamin E, 10% glycerol, 4.5% gum acacia powder). Here, improvement in perspiration and rub fastness was also noticed.
