Textiles et tissus imprimésIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This paper presents an initial study from a more extensive programme of research at the design/technology interface that is focused on the use of design methodology as a means to lower the environmental impact of fashion clothing. The leaves and bark that are by products of the responsibly farmed eucalyptus used in the manufacture of lyocell fibres were extracted with water to provide a source of natural colour. Lyocell fabric, which required minimal preparation, was screen printed with an aqueous paste containing only the extracted colour and a natural thickener to provide attractive golden-yellow prints. The printed fabrics demonstrated surprisingly good fastness towards light, washing and rubbing. A mordanting pretreatment of the lyocell with alum modified the colour of the naturally coloured prints to become stronger and duller, but provided no advantage in terms of technical performance. The outcome presents a potentially useful model for the development of sustainably coloured fashion textile products. Note de contenu : - Material

solvantsIndex. décimale : 667.9 Revêtements et enduits Résumé : In this work, flatbed screen printing is evaluated regarding its capability to produce catalyst layers of PEM fuel cells. In the field of printed electronics, screen printing is regarded as robust and high-throughput coating technology. The possibility of in-plane structuring could be an additional degree of freedom, enabling more complex designs of catalyst layers in the future. In this study, process parameters are varied to investigate their effect on resulting layer thickness, homogeneity, and Pt-loading. With the usage of different screens, the Pt-loading can be adjusted. Additionally, two different pastes with and without water content are investigated. The catalyst paste without water showed a better process stability during printing and performed best under dry conditions (RH = 40%) and worst under wet conditions (RH = 100%) during electrochemical in-situ testing. Overall, the reproducibility of the CCM production process was verified. The viscosity of the catalyst paste with 19.55 wt% water in solvent was higher compared to the paste without water. Furthermore, a carbon paste (Pt-free) is developed in a similar viscosity range as the catalyst pastes. The main challenge of screen printing process development lies in the paste optimization to prevent evaporation effects over time, ensuring sufficient wetting of the paste on the substrate and sufficient fuel cell performance.

ThermochromieIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The objective of this work was to study how ultraviolet (UV) light exposure, washing and rubbing can influence colour and dynamic qualities of chromic textiles, and to explore how the results attained can be applied by designers for the development of colour changing palettes. The experimental work was conducted with 74% polyamide and 26% elastane elastics screen printed with thermochromic, photochromic and hydrochromic pigments in diverse colours. Initially, colourfastness properties of each pigment type versus colour were assessed. Although washing and rubbing can interfere in samples' colours by becoming lighter at different degrees, the results attained highlight the poor stability to lighting of thermochromic and photochromic pigments, which also present changes between hues along exposure time. For conventional textile applications, poor colour fastness commonly represents a limitation. This work proposes that the way textile colours and behaviour are permanently affected by the studied conditions can be interpreted as a creative variable in the design process. Research samples with a combination of pigments were developed and tested with a combination of cycles of different fastness tests, namely one washing cycle for every 4 h of UV light exposure, totalling 48 h and 12 washing cycles. Results demonstrate the possibility of creating interactive surfaces capable of displaying a wide range of colours that evolve to static within different hues, over stimuli conditions.

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.
