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

Traîtements de surfaceIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Both the dyeing and finishing of textiles with natural compounds are gaining increasing attention because of various environmental and health problems associated with the use of synthetic reagents. In this study, wool fibres were dyed with three natural dyes, namely, Arnebia euchroma, cotton pods and harmal seeds. Alum was used as the mordant, and samples were mordanted by the premordanting method. Oxygen plasma was employed for the surface modification of wool. Plasma treatment time, alum concentration, dyebath temperature and pH were selected as the process variables, and their effects on the K/S of the dyed samples were analysed using D-optimal design. The surface topography, morphology and chemistry of the wool fibres after plasma treatment were studied by atomic force microscopy (AFM), scanning electron microscopy (SEM) and Fourier Transform–infrared spectroscopy (FTIR), respectively. FTIR confirmed the creation of new oxygen-containing groups on the surface of wool fibres after plasma treatment. SEM and AFM images confirmed the surface etching and increase in the roughness of plasma-treated fibres. Increasing the dyebath pH and temperature increased the K/S of the dyed samples. Increasing the amount of alum mordant increased the K/S of samples dyed with cotton pods but decreased the K/S of samples dyed with A. euchroma and harmal seeds. Increasing the plasma treatment time improved the K/S of samples dyed with A. euchroma and cotton pods but had no significant effect on the K/S of samples dyed with harmal seeds.

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).

Sulfate de cuivreLe sulfate de cuivre est formé par la combinaison d'un ion cuivre (Cu2+) et d'un ion sulfate (SO42- ). Il a donc pour formule : CuSO4. Il est commercialisé soit anhydre, avec cette formule, soit pentahydraté et a alors la formule CuSO4,5H2O, comme sur la figure ci-contre. Il existe également avec une ou trois molécules d'eau d'hydratation.
FABRICATION : Le sulfate de cuivre est obtenu industriellement comme sous-produit du décapage chimique du cuivre par l'acide sulfurique. Cet acide n'attaquant pas le cuivre métallique, seule sa forme oxydée présente en surface sous forme d'oxydes, de carbonates (vert de gris) et autres, passe en solution. Dans ces conditions, seul le degré d'oxydation II (forme cuivrique) est stable.
UTILISATION : Une des principales utilisations actuelle du sulfate de cuivre est la préparation (industrielle ou non) de fongicides pour l'agriculture y compris biologique. La forme la plus courante est la bouillie bordelaise constituée de sulfate de cuivre neutralisé par la chaux.
TOXICITE : Le sulfate de cuivre est un produit toxique.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Cotton and wool fabrics were dyed with nine natural dyes obtained by aqueous extraction of the original plants/insect in an attempt to reconstruct traditional textile dyeing recipes, to optimise the methodology at all stages, i.e. extraction, mordanting and dyeing, and to standardise it. Cochineal, madder, alkanna, henna, brazilwood, red sandalwood, safflower, indigo and logwood were used for the dyeings, which were carried out directly and after mordanting of the textile material. A variety of mordants, namely, aluminium potassium sulphate, potassium dichromate, copper sulphate, zinc chloride, iron(iii) chloride, iron(ii) sulphate and tin chloride, is anticipated to meet both early and recent requirements and options. The dyeings were evaluated through colour measurements and standard wash, light and rub fastness tests. Generally, the mordanting process known for many centuries and connected with the textile dyeing resulted in an improvement in dye absorption and fastness properties mainly for the cotton samples, as is concluded from the tests and measurement assessments.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The plant colorant annatto was investigated to determine its potential use as a natural dye for conventional and novel textile applications. Alum was selected as a mordant. Different techniques of mordanting and a broad set of variations in the dyeing recipes were applied to achieve optimisation and an improvement in colour fastness properties. Quality control of all dyeings was performed using standard fastness tests and colour measurements. Printing of cotton fabrics was also achieved with annatto using the flatbed screen-printing technique. Measurement of the rheological and physical properties of the annatto printing paste confirmed its stability and suitability for conventional printing. Fastness properties of the conventionally printed annatto fabric were also measured. A novel water-based digital printing ink using annatto was prepared and applied to cotton fabric using a digital printing application. The physical properties of the annatto ink-jet ink were also measured. Wash, light and rub fastness properties of the annatto digitally printed fabric were determined and compared with those of conventional printing methods. The results were promising for annatto as a natural colorant, which possibly paves the way for the development of a new range of natural environmentally friendly dyes.

VinyltriméthoxysilaneIndex. décimale : 668.9 Polymères Résumé : The influence of hot water and the water-carrying agent aluminum potassium sulfate dodecahydrate (alum) on the mechanical and thermal properties of the silane-water crosslinked linear low density polyethylene (LLDPE) was investigated. LLDPE was melt-grafted with various content of vinyl trimethoxysilane (VTMS) using dicumyl peroxide (DCP) as initiator. The results show that the contribution of hot water to gel content is poor, about 2 to 16 %, compared with that of the silane grafted LLDPE. Is feasible to achieve silane-water crosslinking reaction with alum for self-crosslinked LLDPE; furthermore, the self-crosslinked LLDPE has lower crosslink density (m). It was found that alum could not only conduct silane-water crosslinking reaction effectively, but also improve the mechanical properties, especially the elongation behavior. The heat of fusion (DHm), the melting temperature (Tm), and the degree of crystallinity (Xc) of the hot water crosslinked LLDPE decreased with the advancement of VTMS. The Avrami exponent n of self-crosslinked sample was larger than that of hot water crosslinked sample. This means that the alum could contribute to the growth of crystallization.
