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).

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A reactive dispersant (SMA–ESA) was synthesised from poly(styrene‐alt‐maleic anhydride) (SMA) and 4‐(beta‐sulfatoethylsulfonyl)aniline (ESA), and its dispersing ability for carbon black (CB) was investigated. Fourier transform infrared (FTIR) and 1H–nuclear magnetic resonance (NMR) spectroscopies showed that an amidation reaction took place between ESA and SMA. The optimal preparation conditions for reactive nanoscale CB dispersion were a mole ratio of ESA to SMA of 4:3, with a mass ratio of SMA–ESA and CB at 3%, sonication time 20 min, and pH 8. The reactive nanoscale CB dispersion prepared under optimal conditions showed excellent stability and small mean particle size. A cotton fabric coloured with reactive nanoscale CB dispersion could obtain a high K/S value, and excellent rubbing and washing fastness.

GlycérineLe glycérol, ou glycérine, est un composé chimique de formule HOH2C–CHOH–CH2OH. C'est un liquide incolore, visqueux et inodore au goût sucré, utilisé dans de nombreuses compositions pharmaceutiques. Sa molécule possède trois hydroxyles correspondant à trois fonctions alcool responsables de sa solubilité dans l'eau et de sa nature hygroscopique. Un résidu glycérol constitue l'articulation centrale de tous les lipides de la classe des triglycérides et des phosphoglycérides.
PROPRIETES PHYSIQUES : Le glycérol se présente sous la forme d'un liquide transparent, visqueux, incolore, inodore, faiblement toxique si ingéré (mais laxatif à haute dose), au goût sucré.
Le glycérol peut se dissoudre dans les solvants polaires grâce à ses trois groupes hydroxyles. Il est miscible dans l'eau et l'éthanol ; et insoluble dans le benzène, le chloroforme et le tétrachlorométhane.
Son affinité avec l'eau le rend également hygroscopique, et du glycérol mal conservé (hors dessicateur ou mal fermé) se dilue en absorbant l'humidité de l'air.
- PROPRIETES CHIMIQUES : Dans les organismes vivants, le glycérol est un composant important des glycérides (graisses et huiles) et des phospholipides. Quand le corps utilise les graisses stockées comme source d'énergie, du glycérol et des acides gras sont libérés dans le sang.
- DESHYDRATATION : La déshydratation du glycérol est faite à chaud, en présence d'hydrogénosulfite de potassium (KHSO3) et produit de l'acroléine
- ESTERIFICATION : L'estérification du glycérol conduit à des (mono, di ou tri) glycérides.
- AUTRES PROPRIETES : Le glycérol a un goût sucré de puissance moitié moindre que le saccharose, son pouvoir sucrant est de 0,56-0,64 à poids égal13.
Le glycérol a des propriétés laxatives et diurétiques faibles.
Comme d'autres composés chimiques, tels que le benzène, son indice de réfraction (1,47) est proche de celui du verre commun (~1,50), permettant de rendre "invisibles" des objets en verre qui y seraient plongés.

ThiolsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The aim of this work was to study the influence of a glycerol derivative with thiol groups, 3,6‐dithia‐1,8‐octanediol (DTO), on light fastness of prints overprinted with water‐based flexographic printing inks. Laboratory printing was performed on various plastic films (BOPP and PE). The effect of a small amount of DTO on printing ink colour was examined by studying the optical density of a full tone area, relative printing contrast and the colour values (CIELAB), and the total colour difference ΔE*ab. Artificial ageing was applied in order to investigate DTO influence on colourfastness of CMY printing inks. Densitometry and spectrophotometric parameters were measured during artificial ageing by irradiation. Additionally, FTIR spectroscopy was used to observe the changes in ink film on printing bases before and after ageing. The print quality of investigated prints is widely discussed. In general, DTO addition influenced the printability of the plastic film and the optical density of a full tone area with an acceptable total colour difference ΔE*ab. Furthermore, printing inks with added DTO exhibited higher optical density and smaller changes of ΔE*ab during artificial ageing. Moreover, the FTIR spectra of printing ink films with added DTO after ageing did not exhibit any perceptible changes in contrast with the original printing ink.

Triacétate de celluloseLe triacétate de cellulose, aussi appelé triacétate, est un polymère artificiel. En effet, il est fabriqué par traitement de la cellulose par l'acide acétique.
Le triacétate se compose de trois molécules d'acétate sur une couche de cellulose.
Il est chimiquement similaire à l'acétate de cellulose et au diacétate de cellulose.Index. décimale : 667.3 Teinture et impression des tissus Résumé : Light transmission through multiple sheets of undyed cellulose triacetate fabric immersed in binary solutions of carbon disulfide and n‐heptane has been measured using ordinary absorption spectroscopy. The optical transmission of light in the visible spectral range is found to be very high at wavelengths corresponding to a match between the index of refraction of cellulose triacetate and that of the surrounding solution. This phenomenon is commonly referred to as the Christiansen colour filter effect. Indices of refraction of cellulose triacetate from 400 to 700 nm were derived from these data.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Alkyl imidazole cationic Gemini surfactants (AICGS) with various alkyl chain lengths were used as retarders for dyeing methylene blue (MB) on polyacrylonitrile (PAN) fabrics, with benzyldimethyldodecylammonium chloride (1227) surfactant as a comparison. The exhaustion (E%) of MB on PAN fabrics was investigated at varying surfactant concentrations and dyeing temperatures. Furthermore, kinetic studies on various retarders and 10‐4‐10 AICGS concentrations were carried out. It was found that the retarding dyeing effect of AICGS is stronger when compared with the 1227 surfactant. Moreover, as surfactant concentration increased or the dyeing temperature decreased, E% was reduced drastically. For kinetic studies, the dyeing rate constant increased with an increase in dyeing temperature and a decrease in 10‐4‐10 AICGS concentration, while half‐dyeing time was reversibly decreased.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Polyurethane/clay nanocomposite (PUCN) filaments were spun by the dry‐jet‐wet spinning method. To prepare the PUCN filaments, 0.25, 0.50 and 1% of nanoclay on the weight of polyurethane were incorporated in the polyurethane dope. The interaction between clay and polyurethane was analysed by attenuated total reflectance–Fourier Transform‐infrared (ATR‐FTIR) spectroscopy. The structure and morphology of the PUCN filaments were analysed by wide‐angle X‐ray diffraction (WAXD) and transmission electron microscopy (TEM). Both the neat polyurethane and the PUCN filaments were dyed with different acid, basic and reactive dyes. The neat polyurethane filaments exhibited poor dyeability with all three classes of dyes. By contrast, the PUCN filaments showed a significantly higher dye uptake with all of the dyes used. Furthermore, the dye uptake increased significantly as the percentage of clay in the filaments increased, as indicated by the increase in the K/S values of the dyed filaments. The dyeing mechanism with all three dyes, as well as the increased dyeability of the PUNC filaments in comparison to those of the neat polyurethane filaments, was discussed.

Textiles et tissus -- Propriétés mécaniquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Polyethylene terephthalate nanocomposites containing six modified montmorillonite nanoclays were prepared by a melt compounding technique. The effect of intercalated compounds of montmorillonite on textile mechanical properties of resultant polyethylene terephthalate nanocomposite fabrics was investigated. Winding was not possible, when the polymers were first compounded with the desired amount of montmorillonite and then spun, as filament breakage occurred. Spinable polymer were only obtained by mixing polyethylene terephthalate master batches with 4 wt% montmorillonite, which contained tallow intercalating compound with pure untreated polyethylene terephthalate to a montmorillonite content of 0.5 wt%, thus decreasing the concentration of thermally degraded polymer chains. After spinning the fibres were drawn and knitted into fabric samples for further testing. The prepared polyethylene terephthalate nanocomposite fabrics using montmorillonite exhibited higher colour strength using vat and disperse dyes compared with those of the reference fabrics made from fibres spun without montmorillonite clay content and regular fabrics. The carbocyclic‐based vat dyes have higher colour strength values on polyethylene terephthalate nanocomposite fabrics if compared with heterocyclic‐based vat dyes. The colour fastness ratings for both vat and disperse dyeings secured very good to excellent washing and perspiration fastness on polyethylene terephthalate nanocomposite fabrics. All dyed fabrics showed excellent light fastness using vat and disperse dyes. The preparation of polyethylene terephthalate nanocomposite fabrics with improved textile mechanical and vat dyeing properties needs further investigations.

Thirteen ink‐jet printing experts were interviewed to understand how they manage colour and their process for analysing and comparing colour gamut. A significant result of this study was the development of a four‐stage process model for colour gamut analysis and print quality evaluation for textile ink‐jet printing. The optimal process model was verified and approved by experts. This study uncovered an industry initiative toward the improvement of CMS for more accurate colour matching, a need to stabilise variables in the manufacturing process, and a need to standardise related tests and evaluations. The study also revealed new CMS software and technologies developed for ink formulation and pre‐/post‐treatment methods to facilitate high quality production in textile ink‐jet printing.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Freshwater is an increasingly scarce resource that is extensively used in textile wet‐processing. In seeking to identify alternative low freshwater‐usage coloration technology, this study examined the potential use of seawater (SEAW) as the dyeing medium for wool coloration using a range of reactive dyes. Initially, the dyeing behaviour of the wool fabric in simulated seawater (SSW) was compared with conventional dyeing from distilled water (DW) using α‐bromoacrylamide‐based Lanasol dyes and sulphatoethyl sulphone‐based Remazol dyes. These preliminary studies demonstrated that comparable coloration could be achieved in the SSW medium based on an assessment of the dye exhaustion, dye fixation, colour yield and levelness. Subsequent dyeing studies of wool using Mauritian seawater with both the Lanasol and Remazol reactive dyes confirmed that, based on the dye exhaustion, dye fixation, colour yield and levelness, comparable coloration could be achieved, highlighting the possibility of substituting freshwater with seawater as the dyeing medium.
