AlizarineL'alizarine est un colorant rouge d'origine végétale, extrait de la racine de la garance des teinturiers (Rubia tinctorum L.), une plante vivace de la famille des Rubiacées, autrefois largement cultivée pour la teinture qu'elle fournissait.
Colorants dispersésCatégorie de colorants très peu solubles dans l'eau, utilisés à l'origine comme colorants pour l'acétate, et qui généralement sont appliqués sous forme de suspensions aqueuses de faible concentration.Les colorants dispersés sont largement utilisés dans la teinture de la plupart des fibres manufacturées, surtout le polyester.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This article compares the dyeing of cellulose diacetate (cellulose-based) and polyester fabrics using supercritical carbon dioxide (SC-CO2) and aqueous media. The benefits of dyeing in SC-CO2 were clearly demonstrated in laboratory-based and pilot-scale studies in terms of increased colour strength, uniformity, fastness and the absence of auxiliaries such as dispersing agents or surfactants. In addition, the “super-levelling” nature of the SC-CO2 medium was demonstrated in the reprocessing of polyester “waste textile” and the re-use of the “locked-in waste” colourant. The SC-CO2 processing medium can be utilised to accurately colour “multiple life” polyester and cellulose acetate uniformly and to creatively tie-dye polyester and cellulose acetate fabrics. Through SC-CO2 fluid technology, we can envisage a viable waterless circular manufacturing and recycling/remanufacturing framework for the predominantly polyester global fibre market coupled to the sustainably sourced, biodegradable cellulose diacetate as a replacement for cotton. The key technical and commercial advantages being the use of a single solvent dye class for both polyester and the cellulose diacetate, saving on energy costs, integrated simpler processing, reduced water usage and associated efficient recycling. Further, repositioning the cellulosic fibre industry towards using sustainable forests is attractive in terms of improved land, water and environmental management.

Transfert de masseIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Supercritical fluid dyeing is an interesting alternative to the conventional aqueous process because of its environmental benefits. The aim of the paper is to provide the reader with an up-to-date overview of this subject, covering various aspects, such as the solubility and equilibrium partitioning of the dyes, mass transfer phenomena and solvent–polymer interactions occurring during coloration, up to the most recent reports on the technology of the dyeing process. Even though the best results have been obtained in the coloration of synthetic textiles, particular attention is given to the dyeing of natural textiles, which is, at the moment, the limiting step of this technology.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A series of 1-amino-4-hydroxy-2-phenoxyanthraquinone derivatives, substituted with various hydrophobic groups, were applied as dyestuffs in the carbon dioxide supercritical fluid dyeing (SFD) of unmodified polypropylene (PP) fabrics. The dyeability, colour strength, and colour fastness of the dyeing process were evaluated for 14 dyestuffs. The hue of the PP fabrics dyed with a series of dyestuffs was red of near-magenta, but it was slightly less bluish rather than magenta. The differences in dyeing performance regarding the type and position of the substituents were observable in terms of colour strength and colour fastness. On the basis of the evaluation of the colour strength and the colour fastness, this study showed that the type and position of the hydrophobic group attached to the substituted phenoxy ring affected dyeing performance. Comparisons of the dyeing performance of 2- and 4-substituted dyestuffs with the same groups attached suggested that replacement of the 2-position affected colour strength while 4-position affected colour fastness. Similarly, 2,4-disubstituted dyestuff was more suitable on the dyeing performance than 4-monosubstituted dyestuff in which alkyl had twice the amount of aliphatic carbon at one position, and 3,5-disubstituted dyestuff.

TransglutaminaseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : It was reported that supercritical fluids could increase the reaction rates and stability of enzymes. The transglutaminase (TGase) was used as a cross-linking agent for collagen fibre and cattle hide in supercritical carbon dioxide (SCF-CO2) medium. The denaturation temperature (Td) and shrinkage temperature (Ts) of the cross-linked samples were determinated. SCF-CO2 could improve the cross-linking reaction of the TGase with the collagen fibre and cattle hide according to the denaturation temperature determination. For collagen fibre, the Td of TG-SCF-Collagen is about 20°C higher than that of TG-Collagen in water medium. While the Td of cattle hide treated with TGase in SCF-CO2 is about 10°C higher than that of in water medium. Interestingly, the shrinkage temperature of the cattle hide did not show any change while it was treated by TGase both in SCF-CO2 medium and in water. However, the appearence of the hide after TGase treatment was tighter and finer with the area reduction. The results implied that intermolecular cross-linking created by TGase did not like the cross-linking by chrome (III)tanning agents, which formed rigid structures among the collagen fibrils that play the main role for the increase of shrinkage temperature of leather.
