Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Blue poly(styrene-co-methacrylic acid) nanospheres were prepared by dyeing polymer dispersions with CI Disperse Blue 56. The coloured nanospheres had a clear shell with a thickness of 32.5 nm. The average diameter of the nanospheres increased from 288 to 353 nm, and the glass transition temperature was raised from 109.6 to 117.9 °C after coloration. Ultraviolet-visible absorption spectra, transmission electron microscopy, and differential scanning calorimetry show that the amino and/or hydroxyl groups of the disperse dyes formed hydrogen bonds with the carboxyl groups on the surfaces of the nanospheres during the coloration process, resulting in increased particle sizes and shell layers. The dye content increased almost linearly with increasing dye concentrations or dyeing temperatures within a certain range. By increasing the pH of the dyeing bath from 4 to 5, the dye content increased sharply from 0.68 to 1.49% because of the ionisation of the carboxyl groups of the macromolecules.

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).

Traîtements de surfaceIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Cationic copolymer nanoparticles were used to modify Apocynum venetum/cotton blended fabrics. The modified blends were then dyed using CI Acid Red 14. In order to enhance the colour performance, the effects of combined pretreatment using nanoparticles and sodium hydroxide (NaOH) or carboxymethylcellulose (CMC) or plasma were investigated. The results show that combined pretreatment with NaOH and nanoparticles improved the dyeing effect. The optimum concentrations of NaOH and nanoparticles were 100 and 2 g l?1 respectively. In addition, using CMC to pretreat the fabrics could also improve the acid dyeing performance. However, the combination of plasma pretreatment and cationic nanoparticle modification produced the best colour performance for acid-dyed A. venetum/cotton blends. The dye exhaustion rate is highest (up to 95%) with plasma pretreatment. Scanning electron microscopy revealed that combined treatment with plasma and nanoparticles resulted in a far greater number of nanoparticles being deposited on the fibre surface. X-ray photoelectron spectroscopy indicated that the pretreatments with different procedures significantly changed the chemical components of the fibre surfaces. The aromatic rings of acid dye molecules covered the fibre surfaces after plasma and nanoparticle pretreatment and acid dyeing. Note de contenu : - Colour properties of the dyes blends

Alginate de sodiumL'alginate de sodium ou polymannuronate sodique, de formule NaC6H7O6 est un additif alimentaire (E401) utilisé dans les boissons, constitué d’alginate et de sodium. Il se présente sous forme de poudre blanche à blanc crème, inodore et sans saveur, très soluble dans l'eau. C'est une longue molécule extraite d'algues brunes, constituée d'unités de glucides reliées ensemble pour former une chaîne.

Traîtements de surfaceIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Ink dot distribution on cotton fabrics determines the colour performance of reactive dye inkjet printing, and ink drop spreading is one of the important factors influencing the ink dot distribution. In order to reveal the relationship between fabric pretreatment and ink drop spreading, two pieces of cotton fabric were pretreated respectively with sodium alginate and sodium alginate plus high fatty acid derivative solutions. Results indicate that the surface energy of the cotton fabrics was reduced from 73.79 to 69.45 and 58.49 mJ m?2 after the pretreatment with sodium alginate and sodium alginate plus high fatty acid derivative respectively. Correspondingly, the spreading area of cyan ink drops on these fabrics was reduced from 104.9 to 92.5 and 72.3 mm2. Furthermore, on the fabric treated with sodium alginate plus high fatty acid derivative, the strip-like ink dots were narrow and short, which means the dye was concentrated in an area on the fabric surface. Colorimetric values of the inkjet-printed fabrics demonstrated that the high fatty acid derivative would enhance the ability of sodium alginate to control ink droplet spreading, thereby improving the colour performance.

Vapeur d'eauIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A series of padded cotton fabrics with various water contents were obtained through vacuum dehydration. The effects of the water content on the fabric temperature variation during steaming, the colour properties, and the dye fixation rate (%F) were investigated. Dye distribution in the dyed cotton fibres was assessed. The influences of steaming time and sodium carbonate concentration on K/S value and %F of the dyed fabrics with low water content were also evaluated. The results indicate that reducing the water content of the padded cotton fabric to around 25.0% prior to steaming was favoured for reactive dyeing. The temperature of the wet fabric rose rapidly, the K/S value and %F were enhanced, and in addition the dye penetration into the dyed cotton fibres was sufficient. However, for padded fabrics with extraordinarily low and high water contents (e.g. 1.4% and 70.9% respectively), both the K/S value and %F were decreased. Furthermore, a white core phenomenon was evident for the fibres of the dyed fabric with a water content of 1.4%. Variation in the L* values was in line with the K/S values as the fabric water content varied. As expected, steaming time and sodium carbonate dosage can also affect reactive dye fixation greatly and should be determined accordingly for dyeing cotton fabric with low water content.
