Textiles et tissusIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The colours and patterns of coloured textiles are usually obtained via dyeing or printing processes. However, these processes consume large amounts of electricity and cause water pollution, which affects the ecological environment. The hand feel of dyed fabrics is superior to that of printed fabrics. Three-channel rotor spinning is a highly flexible, adaptable and sustainable method for producing coloured textiles by blending precoloured fibres during the spinning process. Additionally, the process requires approximately half the water required for fabric dyeing or printing. Herein, the colour characteristics, as well as the advantages, of the coloured textiles produced by the new method are demonstrated. Three types of Stearns-Noechel models are modified to describe the relationship between the blending ratios and resulting textile colours. The colour-matching accuracy is high. As demonstrated by the results, the three-channel rotor spinning method can effectively promote coloured textile engineering. Note de contenu : - Smart and sustainable spinning of coloured textiles

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This study reviews the evolution of and recent developments in non-aqueous reactive dyeing systems for cotton fibre. As conventional water-based reactive dyeing causes adverse effects to the environment because of the need for huge quantities of water and chemicals, as well as generating a substantial amount of effluents, one of the alternative ways to alleviate pressure on the environment is to switch the dyeing medium from an aqueous water-based approach to a non-aqueous solvent-assisted approach. Among a wide variety of non-aqueous dyeing methods, this review focuses on several non-aqueous dyeing systems, including dyeing textile fibres with chlorinated solvents, dyeing cotton with the use of reverse micellar systems, a dye/solvent suspension system and a non-nucleophilic solvent-assisted dyeing system.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : In this study, cotton fabric and nylon fabric were dyed with a range of commercial sulphur dyes and the light and wash fastness of the coloured fabrics was investigated. The effect of after-treating the coloured cotton and nylon fabrics with a tannin-based commercial product, Bayprotect Cl, in the presence or absence of sodium sulphate in the treatment bath, was found to significantly improve the light fastness of the sulphur-dyed cotton, and the photoprotective effect was partially stable to ISO 105-C06 washing. In addition, the tannin-based after-treatment also improved the colour stability of the dyed fabrics to the perborate-based ISO 105-C06 washing. The possible mechanisms for the improved fastness properties are also discussed. The application of sulphur dyes to nylon is potentially commercially useful but has been limited because of the reported poor light fastness of the dyeings. The photoprotective effect of the tannin-based after-treatment was investigated with a view to providing the necessary commercial performance. However, it was established that on this fibre, the light fastness improvement was marginal, and the associated wash fastness to oxidative bleach-based ISO 105-C06 washing was limited.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Disperse dyes are not currently applied to wool commercially, in large part because of inadequate wash fastness, but they do have potential, especially for wool-polyester blends. In this study, for the first time hydrogen peroxide was investigated to increase the wash fastness of disperse dyes on wool. In the absence of oxidants, 10 disperse dyes from seven classes imparted colours with a range of depths (K /S 2-26) with wash fastness (grey scale ratings for colour change) grades of 3 to 4-5. Hydrogen peroxide had only small effects on colours and gave only small enhancements to wash fastness, which were limited to anthraquinone, nitrodiphenylamine, disazo and coumarin dyes. The bleach activators Prestogen W and citric acid enhanced the bleaching effect of hydrogen peroxide but did not assist with raising wash fastness. Hydrogen peroxide in post-dyeing scouring made the dyeings brighter but did not significantly enhance wash fastness. Ammonium persulphate, which was included for benchmarking with earlier studies, yellowed the wool and decomposed some dyes. This study extends the range of dye classes whose wash fastness on wool can be improved by ammonium persulphate to now include diazo, coumarin and methine, and confirms that oxidants/free radical initiators have potential for enabling the disperse dyeing of wool.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The colour shade quality control scenario is ubiquitous within the cosmetic hair colouring industry. Visual inspection is nowadays the go-to standard for the evaluation of dye application outcomes, even although the increased availability of easily operated spectrophotometers has favoured the introduction of colorimeters in the manufacturing process. Human hairs, however, are very efficient scatterers, and this makes their instrumental measurements more difficult and less consistent. To assess the degree to which this intrinsic property compromises the reliability of spectrophotometric measurements, we tested a variety of samples of human hair locks (swatches), both dyed and undyed, and those of nylon fibre hair swatches. First, we analysed results from two measuring modalities made available by instrumentation: Specular Component Included and Specular Component Excluded. Then, to modify macroscopic spatial orientation, we arranged swatches so that hair strands would cross at varying angles. Measurements confirmed the expected dependencies, namely, the clear influence of the scattered component and of sample orientation on instrumental reading outputs. Having settled on a preferred measuring setup, we analysed measurement variance. Here, we briefly discuss the qualitative visual inspection of spectra, before switching to ΔE to show the unreliability, at least as far as lighter coloured dyes are concerned, of the classic target-sample measurements which are employed to issue pass-or-fail verdicts. Despite quantitative measurements being an asset for quality control, we suggest that greater care should be placed in spectrophotometric readings when human hair is involved, as opposed to more traditional fields of application.

Langues : Anglais (eng) Tags : 'Gestion des couleurs' 'Gamme de 'Sélection 'Mélange couleurs additif' soustractif' Intuition Engagement Conception Index. décimale : 535.6 Couleur Résumé : Colour management is ubiquitous in the digital world. However, despite the many advances in colour management over the last couple of decades, it remains an imperfect process. In the art and design community there is often a level of dissatisfaction and deep cynicism about colour management that can lead to lac of engagement with the process. This research explores colour management in a design context though three issues : the gamut issue , the intuitive issue and the engagement issue ; each relates to areas where colour management could better connect with tacit design knowhow. The work focusses on the selection of colour in a digital context since for many users this is the first touch point that they have with colour management. Psychophysical studies have been carried out in both laboratory and design-studio settings. It is shown that users can better predict the results from subtractive colour mixing than from additive colour mixing. The performance of various types of colour picker are explored and consequences for the design of user interfaces are discussed.

This study presents a novel one-bath/two-stage exhaust finishing process to improve the oxidative wash fastness of CI Leuco Sulphur Black 1-dyed cotton fabric. The effect of the combined Tinofix ECO and Bayprotect Cl after-treatment was to impart better colour fastness to oxidative International Organisation for Standardisation (ISO) 105 CO9 washing of the dyed cotton compared with those dyed fabrics after-treated with Tinofix ECO alone. In addition, while the dyed fabrics rub and light fastness performances were unchanged by the after-treatments, some improvement in the tensile strength of the combined Tinofix ECO and Bayprotect Cl after-treated fabrics was observed.

Five single-colour woven fabrics were woven from five threads of similar hue. One of the samples was chosen as a reference, for which the colour appearance was the goal to be achieved in the two-colour woven fabrics prepared with the other available warp threads and newly dyed weft threads. The colour values of dyed weft threads were predicted by a two-dimensional colour appearance model. With dyed weft threads, managing the colour appearance of the two-colour woven fabric was enabled to achieve the colour values of the reference. In the results, colour deviations between the predicted and measured colour values of weft threads revealed some limitations to the colour appearance model and performance of the dyeing process. After the production of the two-colour woven fabric, the colour appearance matched the appearance of the reference, resulting in deviations of ΔE CMC(2:1) = 1.2-7.8. Moreover, the differences between theoretically predicted and measured colour values of the two-colour woven fabric were evaluated as small, ranging from ΔE CMC(2:1) = 1.5-1.9. The results demonstrated the efficiency of implementing the colour appearance model and the dyeing process of weft threads as an approach to achieve the defined colour appearance of two-colour woven fabrics, which with small colour deviations matches the colour of a single-colour reference.

Langues : Anglais (eng) Catégories : Aluminium L'aluminium est un élément chimique, de symbole Al et de numéro atomique 13. C’est un métal pauvre, malléable, de couleur argent, qui est remarquable pour sa résistance à l’oxydation13 et sa faible densité. C'est le métal le plus abondant de l'écorce terrestre et le troisième élément le plus abondant après l'oxygène et le silicium ; il représente en moyenne 8 % de la masse des matériaux de la surface solide de notre planète. L'aluminium est trop réactif pour exister à l'état natif dans le milieu naturel : on le trouve au contraire sous forme combinée dans plus de 270 minéraux différents, son minerai principal étant la bauxite, où il est présent sous forme d’oxyde hydraté dont on extrait l’alumine. Il peut aussi être extrait de la néphéline, de la leucite, de la sillimanite, de l'andalousite et de la muscovite.
L'aluminium métallique est très oxydable, mais est immédiatement passivé par une fine couche d'alumine Al2O3 imperméable de quelques micromètres d'épaisseur qui protège la masse métallique de la corrosion. On parle de protection cinétique, par opposition à une protection thermodynamique, car l’aluminium reste en tout état de cause très sensible à l'oxydation. Cette résistance à la corrosion et sa remarquable légèreté en ont fait un matériau très utilisé industriellement.
L'aluminium est un produit industriel important, sous forme pure ou alliée, notamment dans l'aéronautique, les transports et la construction. Sa nature réactive en fait également un catalyseur et un additif dans l'industrie chimique ; il est ainsi utilisé pour accroître la puissance explosive du nitrate d'ammonium.

Métaux -- Oxydation anodiqueIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Existing structural coloration methods using thin films, commonly implemented in high-purity aluminium, produce colours which are highly dependent on the viewing angle because of the inherent angular dependence of thin film interference. Adapting the thin film coloration mechanism to anodisation of industrial-quality aluminium alloys, which scatter light more efficiently than their high-purity counterparts, reduces angle dependence in the colour produced. This reduction of angle dependence, as well as the wide use of anodised aluminium in consumer products, suggests that structural colour based on anodised aluminium could potentially be scaled up for commercial scale production.
