CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Ink-jet printing of cellulosic fabrics with reactive dyes typically requires that the fabric is pretreated with alkali, prior to printing, to facilitate efficient fixation of the dye. In this paper we evaluate the use of sodium formate and other carboxylate salts as a neutral (pH 6.5) pretreatment process. The thickened, prepared-for-print pad liquor contained at least 50 gdm−3 of the selected carboxylate salt and was applied to the cotton fabrics by a pad-dry procedure. The fabric was then ink-jet printed with reactive dye inks, followed by standard steaming and washing-off processes. The pH of the carboxylate salt pretreatment was 6.5 and the aqueous extracts from the print fabrics at the end of the steaming process remained at pH 6.5. It was observed that even at pH 6.5, in the presence of selected carboxylates, significant reactive dye fixation could be achieved on a cotton substrate, whereas in the absence of the carboxylate, very little or even zero fixation was achieved. Infrared and capillary electrophoresis analyses of model reactions of reactive dyes with the carboxylate salts indicated that reactive ester residues were formed, and which subsequently promoted reaction with the cellulosic substrates. In addition to improving reactive dye fixation in ink-jet printing, the carboxylate-modified dyes were also demonstrated to improve long-liquor dyeing properties on cotton substrates. As an extension of this carboxylate-based printing process, the incorporation of lithium acetate (100 gdm−3) into the ink formulation was further studied and it was demonstrated that the necessity for a preparative pretreatment process could be eliminated.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The importance of quinonoidal planarity in improving the wet fastness of acid dyes was studied in a new series of N-sulphonatoalkyl-substituted indophenine derivatives. These derivatives were synthesised via the sulphonatoalkylation reaction of isatins with alkanesultone or sodium bromoalkanesulphonate followed by the indophenine reaction. The effects of the position of sulphonic acid groups, length of the alkyl chain, and electron-donating/withdrawing groups on geometry, electronic structure, solubility, and absorption properties were systematically examined and correlated with the performances of the dyes on wool, silk and nylon fabrics. The N-sulphonatoalkyl indophenine dyes could exhibit a blue colour in N,N-dimethylformamide (DMF) and on silk or nylon fabric but a purplish colour in water and on wool fabric. Methoxy groups had a negative impact on the molar extinction coefficient and dye exhaustion, leading to relatively poor dyeing performance. In comparison, fluorine or chlorine atoms were less influential. The introduction of nitro groups could induce a yellowness to the dyed fabrics caused by the strengthened absorption at the region of 360 to 420 nm and reduce the dyeing rate and wet fastness level due to the low dye–fibre affinity. In general, the N-sulphonatoalkyl indophenine dyes exhibited satisfactory washing and rubbing fastness, especially on dyed nylon fabric. This study provides insight into the structure–property relationship of indophenine dyes and demonstrates that sulphonatoalkylation is an efficient methodology for designing high-performance textile dyestuffs based on quinonoidal heterocyclic structures.

TautomérieIndex. décimale : 667.2 Colorants et pigments Résumé : In this study, five new pyrazolyazo pyrazole dyestuff syntheses are reported. For this purpose, 5-amino-4-arylazo-3-methyl-1H-pyrazoles were diazotised and coupled with 3-amino-5-hydroxy-1H-pyrazole. Fourier Transform–infrared, ultraviolet-visible and proton nuclear magnetic resonance spectroscopy were used to investigate the properties of aminopyrazole-based dyes obtained in this study. The maximum absorption wavelengths of these dyes in various solvents were determined. The theoretical calculations of the molecules in the ground state were performed with the density functional theory/Becke 3-parameter and Lee–Yang–Parr/6-311G(d,p) method by using the Gaussian 0.9 W program. The results were compared with the corresponding experimental data. Acid-base and substituent effects on the absorption spectra of dyes were also examined and reported.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A new dye-modified poly(ethylene oxide)–poly(propylene oxide) polymer, in which the dye molecule (CI Disperse Red 60) is bonded onto polyether monoamine via a triazine ring, was synthesised for the preparation of dye aqueous dispersions and was characterised by Fourier Transform-infrared spectroscopy, 1H nuclear magnetic resonance spectroscopy and elemental analysis. This polymer exhibits unique dispersing performance for CI Disperse Red 60. The mechanism behind the improved performance is briefly discussed with the help of adsorption isotherms. The results indicated that the hydrophobic dye group of this polymer can strongly adsorb onto the dye particle surface through π–π interaction while its long hydrophilic poly(ethylene oxide) chains allow the formation of a thick layer around the dye particles. It was speculated that the adsorbed polymer molecule on the dye surface would form a brush-like monolayer conformation. The dyeing performance of the prepared dye dispersions on polyester fabrics was also investigated. It was found that this polymer can effectively increase the apparent solubility of disperse dye. The dyed fabrics showed very good to excellent fastness to washing and rubbing, while the dyeing effluent was colourless.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : New dyes – aliphatic esters of 1,6,7,12-tetrachloroperylene-3,4,9,10-tetracarboxylic acid – were prepared as potential fluorescent light-stable colorants for high-visibility safety wear. The structure of the 15 perylenes was confirmed by 1H and 13C nuclear magnetic resonance spectroscopy and mass spectrometry, and their spectroscopic and physicochemical properties were determined. An attempt was made to apply the synthesised products as disperse dyes in the coloration of polyester as well as in the mass coloration of polystyrene and poly(methyl methacrylate). The light, wash, and rubbing fastness of the dyeings were determined, and chromaticity coordinates of selected samples were measured and discussed.
