TeintureIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A semi-quantitative study of willow bark dye adsorption on two different cellulose materials using biomordants was carried out. The studied celluloses were microcrystalline cellulose (MCC) AaltoCell and regenerated Ioncell-F (IC) fibres. The dye was a hot water extract of willow bark and the adsorption to cellulose was carried out using carboxylic acid-containing biomordants, namely, oxalic acid, citric acid and tannic acid. Alum was employed as the reference mordant. A semi-quantitative estimation of the dye uptake was conducted using high-performance liquid chromatography equipped with a diode array detector and also by visual inspection, as well as an evaluation of the coloration using CIELab parameters. The mechanism of the dye adsorption on the cellulose surfaces was studied via Fourier Transform–infrared spectroscopy. According to the results, MCC had a higher affinity for polyphenolic dye than the regenerated cellulose fibres. Dye uptake on MCC was 50%-80% and 44%-57% on IC. For MCC, the biomordants improved the dye uptake more effectively than the control mordant, alum, whereas for IC the biomordants were less effective than alum.

Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Acidic and alkaline pectinases have proved efficient for the scouring of cotton. Peracetic acid can be used as an alternative for the bleaching of cotton. As a result of similar conditions of activity, we decided to try to scour and bleach a cotton fabric with both agents simultaneously in a single bath. Prior to performing these experiments, using the viscometric method we proved that pectinases retained their activity in the presence of peracetic acid. We tried to improve the efficiency of the single-bath treatment with the addition of a chelator. Tetrasodium pyrophosphate, which does not deactivate pectinases, has proved an efficient chelator. The analyses of a cotton fabric treated in a single bath with acidic and alkaline pectinases confirmed the efficiency of such treatment. A sufficient quantity of wax and pectin
was removed and, because of that, the absorbance of the treated fabric was improved. The damage to the cotton fibres was negligible and the degree of whiteness obtained was uniform and adequate for further dyeing.DOI : 10.1111/j.1478-4408.2007.00118.x En ligne : http://onlinelibrary.wiley.com/doi/10.1111/j.1478-4408.2007.00118.x/pdf Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3137

Langues : Anglais (eng) Catégories : Coton Le 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).

Textiles et tissus -- LavageIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A study on bioscouring of cotton yarn with the pectinase enzyme was carried out and the results compared with the usual alkali scoured material. The results indicate that the bioscoured yarn has lower percentage of non-cellulosic constituents (impurities), higher tenacity, higher absorbency and the same whiteness after hydrogen peroxide bleaching as compared with the Solomatic bleached yarn. A similar study on cotton fabric indicates that a combined desizing and bioscouring is not feasible at least at ambient temperature. More work, however, is required to compare bioscouring followed by bleaching with the Solomatic or two step scouring and bleaching methods. One interesting finding is that the efficiency of washing of the desized fabric improves on adding ethylene diamine tetraacetic acid sequestrating agent in the wash liquor. Additional advantages of bioscouring are lower energy cost and more easily biodegradable effluent in comparison to alkali scouring.

VertIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Malachite Green (MG) dye was removed from aqueous solutions by the brown alga Dictyota cervicornis. The effects of initial solution pH (3, 4, 5, 6, 7, 9 and 11), contact time, initial dye concentration (5, 25, 50, 75, 100 and 125 mg l−1) and biomass concentration (0.2, 0.6, 1.0 and 1.4 g l−1) on MG adsorption were studied. The highest adsorption capacity was observed at pH 9. Biosorption kinetics were described by the pseudo‐second order model. The Langmuir model predicted the maximum adsorption capacity occurring at a relatively high value of 230 mg g−1. The chemical modification of functional groups, potentiometric titration, Fourier Transform–infrared (FTIR) analysis of the biomass before and after biosorption, and ICP analysis of the solution after MG adsorption, were also performed. The quantities of strong, weak and very weak acidic sites obtained by potentiometric titration were 1.23, 0.88 and 0.29 meq g−1 of dry biomass, respectively, with a total acidity equal to 2.4 meq g−1. FTIR spectra of the pristine biomass showed the presence of carboxylic, sulphonic, hydroxyl and amine functional groups on the biomass structure. There were no obvious differences in the spectra of the biomass before and after MG adsorption. Chemical modification of the functional groups did not affect biosorption. Therefore, MG was removed via a physical mechanism. K(I), Ca(II), Na(I) and Mg(II) ions were released into the solution upon MG adsorption.

Titre : Biosynthesis and synthesis of natural colours Type de document : texte imprimé Auteurs : Timothy L. Dawson, Auteur Année de publication : 2009 Article en page(s) : p. 61-73 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : In nature, the detection of colours requires an organism having some type of eye with a retina and two or three types of photoreceptor connected to a nervous system, which can interpret the signals received. Evidence that certain simple organisms were coloured 1 billion years ago, and some more advanced creatures, which could have possessed eyes a few hundreds of million years ago, is exemplified. A vast array of chemicals essential to life are produced by living organisms and their biosynthesis depends upon individual genetic patterns, which determine the enzyme catalysts involved. Plants photosynthesise many pigments, which are essential for them to maximise the absorption of energy from the sun, while others offer protection from any harmful radiation. Such pigments, for example chlorophylls and the carotenoids, flavonoids and betalains, have traditionally been used as natural dyes, food colorants and medicines. This review compares the chemical processes involved in their biosynthesis and the laboratory methods adopted to confirm their chemical structure. Some engineered biosynthetic methods are now used for commercial production of natural colours and these methods may involve the controversial use of genetic engineering.
