LutéolineLa lutéoline ou lutéolol est un composé chimique de la famille des flavonoïdes, et plus spécifiquement l'une des flavones les plus communes. Elle fut isolée pour la première fois par le chimiste français Michel-Eugène Chevreul à partir de la gaude (autre nom du réséda des teinturiers, une plante utilisée autrefois pour fabriquer de la teinture jaune).

Rouge (couleur)Index. décimale : 667.3 Teinture et impression des tissus Résumé : This paper reports on the colorimetric properties of natural dyes from madder and weld plants. For both crops, a comparison is made among several individual dye compounds and the total plant extracts. Dyeing properties, colour properties and colour stability have been studied. Insight has been gained into the role of the major dye compounds present in the plant. For madder as well as for weld, the use of the total plant extract is considered to be advantageous over the use of individual dye compounds in terms of solubility, colour tone and stability towards light, and non-coloured components present in the plant extract are considered to be responsible for increasing the solubility and the stability of the dye compounds.

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).

SérigraphieIndex. décimale : 667.9 Revêtements et enduits Résumé : This research was concerned with an investigation of cotton print qualities that were achieved by inkjet printing and screen printing. The acrylic binder, S-711, with a pigment-to-binder (P/B) ratio of 1:2 (by weight) was used to produce one set of inkjet inks. BR-700 was used in the creation of another set of screen inks. Furne silica was added to the screen ink to increase the viscosity so that the ink would meet the rheology requirements. The viscosity and flow behaviour of both inks were acceptable. Both the ink viscosity and the particle-size distribution were slightly increased during storage at an ambient temperature for two months. The inkjet ink printed tabrics were pretreated with a solution of poly(ethylene oxide) having 2 to 3 million Dalton molecular weight. The printed fabrics from both inks were analysed for colour saturation, colour gamut and their volume, density, tone reproduction, stiffness, air permeability, and crock fastness. The type, concentration and P/B ratio were exactly the same in both inks in the pigment dispersions. Even though the loaded ink volume on fabrics, by inkjet, was tuned to be approximately the same in optical density as that given by the screen ink, by a multipass mode printing, both printed fabrics gave different colour saturations, colour gamuts and tone reproductions. The colour gamut volume, stiffness, air permeability and crock fastness of the inkjet inks are superior to those of screen inks. The print quality of the inkjet printing on cotton fabric was, thus, better. However, the inkjet ink printed cotton fabric needed to be printed three times to produce the same colour and tone reproduction as that produced by screen printing.

Textiles et tissusIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Colour fading is a method that is used to achieve a vintage look in textile goods. It is desired by customers in the textile market. Additionally, customers demand that these types of products are produced by environmentally friendly methods. In this study, sodium hypochlorite and ozone were used as laboratory-scale colour fading reagents on dyed cotton fabrics. Cotton fabrics were dyed with four different primary colours: red, yellow, blue and black. Dyed fabrics were subjected to ozone and sodium hypochlorite treatment under different treatment conditions. Ozone was chosen as an alternative for comparison and it was applied at fixed flow rate (5 L/min) and time (10 minutes). Colour differences, chemical oxygen demand, bursting strength and energy, water and chemical consumptions were measured. The surface morphology was characterised by scanning electron microscopy. We can conclude that ozonation is effective in discharging colour from dyed fabric samples, and the colour-fading effect is uniform, like in sodium hypochlorite treatment. It was observed that both processes are similar in terms of strength and surface modification. Results showed a 90% cost reduction, 85% water conservation and a 26% chemical oxygen demand reduction.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The main objective of this study was to evaluate the effect of bio-mordants versus metal mordants in terms of colour measurement, colour fastness, and antibacterial properties of a natural dye extract (Hibiscus sabdariffa L.) on the cotton fabric. Accordingly, some bio-mordants including tannic acid, pine cone, lemon peel, and sodium alginate, as well as some metal mordants such as iron(II) sulphate, copper sulphate, zinc sulphate, and aluminium potassium sulphate were investigated based on three conventional mordanting procedures (pre-, meta- and after-mordanting). The method appropriate for H. sabdariffa dyeing on the cotton fabric, according to the colour fastness factor, was found to be the after-mordanting method. The bio-mordants used in this study, the same as metal salts, increased the colour fastness on the dyed cotton fabrics and produced excellent light fastness (rating of 5 to 6), wash fastness (rating of 4 to 5), and dry/wet rub fastness (rating of 4 to 5). The higher antibacterial activities (> 90% bacterial reduction) against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa were observed when tannic acid, pine cone, and lemon peel were applied to the dyed cotton fabric. The use of bio-mordants in the natural dyeing of the cotton fabric could be, therefore, recommended due to the biocompatibility and non-toxicity of natural mordants, along with excellent colour fastness and appropriate antibacterial properties.

This paper reviews a few open challenges in the domain of computational materials design related to the colour appearance of materials. These relatively recent fields of research necessitate revisiting the fundamentals of colorimetry, such as reflectance models. First, we address the virtual design and the simulation of innovative materials, which requires modelling their appearance and fundamental properties. Then we discuss the latest advancements in the machine‐learning domain that have highly revolutionised computational and data‐minded methodologies, which are used for the design innovation, discovery and optimisation of materials.
