Citrique, AcideL'acide citrique est un acide alpha hydroxylé de formule C6H8O7.
Il joue un rôle central dans le métabolisme de tous les organismes vivants et tient son nom de son origine; le citron.
L'acide citrique est biodégradable et n'est pas toxique pour l'homme ni pour l'environnement. Cependant, comme tout acide, il est irritant et peut provoquer des brûlures s'il entre en contact prolongé avec des muqueuses.
À pH physiologique, il est présent sous forme de sa base conjuguée, le citrate, qui est un chélateur de l'ion calcium dans le sang.

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).

The effects of mordant dyeing, CA + SUA crosslinked dyeing, and CPC/CA + SUA crosslinked dyeing on the microstructure and properties of cotton fabrics were compared. The dyeing by the three processes occurred primarily in the amorphous zone of the fibres, and all kept the original crystalline form of the cotton. CA + SUA crosslinked dyeing and CPC/CA + SUA crosslinked dyeing increased the thermal stability of the cotton fabric. CPC/CA + SUA crosslinked dyed cotton obtained excellent dyeing results with the colour depth value (K/S) of 12.3 and rubbing fastness and washing fastness of levels 4–5, and the levelness and dye permeability were acceptable. Furthermore, the antibacterial rate against Escherichia coli and Staphylococcus aureus reached 99.99%, and the ultraviolet protection factor (UPF) reached 50+. Moreover, the wrinkle recovery angle (WRA) increased by 55% compared with raw cotton. This showed that CPC/CA + SUA crosslinked dyed cotton had excellent antibacterial, anti-ultraviolet, and anti-wrinkle performances.

SpyropyraneIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A diverse color-tunable luminous polyurethane leather coating (CLPU) which can reversibly change color as well as fluorescent emission through the UV-vis or UV-darkness circle was prepared, via covalent incorporation of amino-functionalized phosphors and photochromic 1-(2-Hydroxyethyl)-3,3-Dimethylindolino-6’-nitrobenzopyrylospiran (SP). X-Ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-vis absorption spectra, reflectance spectra, fluorescent spectra as well as the migration percentage were measured to characterize the resultant samples structure and properties. In daylight, CLPU appears white before 365 UV irradiation and violet after UV irradiation, due to the transition of the spiro forms of spiropyran to merocyanine forms. In darkness, CLPU emits intense green light before UV irradiation, and the light changes to orange after UV irradiation, due to the phosphors showing pleasant diverse color-tunable luminous effect.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Cotton fabric dyed with natural madder dye exhibits poor dyeing properties. Although mordant improves the dyeing property of cotton fabric, it changes the madder dye colour tonality (the hue angle). In this study, ethylene glycol diglycidyl ether (EGDE) was used as a crosslinking agent to dye cotton fabrics with natural madder dye and improve the surface colour depth (K/S) and colour fastness. The molecular structure, crystal structure and surface morphology of crosslinked dyed cotton were analysed using Fourier Transform–infrared spectroscopy, X-ray diffractometry and scanning electron microscopy, respectively. The results showed that crosslinked dyed cotton fabric had two different ether bonds, and that crosslinked dyeing mainly occurred in the amorphous area. Compared with direct dyed cotton fabric, the hue angle (h°) of crosslinked dyed cotton fabric did not undergo an obvious change, K/S increased by 5, and the rubbing fastness, washing fastness and light fastness increased by 2-3 levels, indicating that the dyeing property of cotton fabric with natural madder dye could be improved by using EGDE as a crosslinking agent. Compared with raw cotton fabric, the bending length of crosslinked dyed cotton fabric was reduced by 2.28 cm, the wrinkle recovery angle increased by 80.7° and the ultraviolet protection factor value was more than 40, indicating that crosslinked dyed cotton fabric had great softness, wrinkle resistance and excellent ultraviolet resistance. In addition, the water contact angle of the cotton fabric only changed slightly after crosslinking dyeing, and the crosslinked dyed cotton fabric still had good hydrophilicity. Therefore, EGDE was a viable crosslinking agent for cotton fabric with madder dye.

Stabilité thermiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Maleic anhydride grafted graphene oxide (GOMA) monomer was prepared by modifying the graphene oxide (GO) with hexachlorocyclotriphosphazene (HCCP), ethylenediamine (ETA) and maleic anhydride (MA). Then a polymeric retanning agent, abbreviated as poly(GOMA-MA-VA) was synthesized from GOMA, MA and vinyl acetate (VA) by free radical polymerization. The structures of GOMA and poly(GOMA-MA-VA) were characterized by Fourier transform infrared (FTIR) spectroscopy, Raman and X-ray photoelectron spectroscopy (XPS), simultaneously, the flammability, UV-resistance as well as the thermal stability and mechanical properties of re-tanned leathers were also investigated. Results show that GO grafted by polymer presents well dispersing stability and can penetrate into collagen fibers to form strong combination with fibers. Furthermore, this novel multifunctional retanning agent can efficiently improve the flame retardance, ultraviolet (UV) resistance, thermal stability and mechanical properties of resultant leather.

Température de retraitIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In a traditional method of chrome tanning, the particle size (PS) of tanning agent is critical for its penetration and the performance of resultant leather. The temperature, pH value and concentration of chrome solution are the important parameters to influence the size scale of the chromium complex. In present study, the PS evolution of chrome tanning agent (CTA) with pH value and temperature changes was investigated firstly, then the influence of the evolution of PS on the tanning process and hydrothermal stability of crust leather was also investigated. The results indicated that with the temperature varied from 25°C to 30°C and 35°C, the pH of the chrome solution increased from 2.5 to 3.8, the PS of CTA increased from 982 nm to 2899 nm, 1265 nm to 3384 nm and 1289 nm to 3630 nm, respectively, showing a rapid increasing tendency. Correspondingly, due to the PS of CTA increased, the chromium absorption rate increased from 31.0% to 53.6% at 25°C, 33.8% to 55.9% at 30°C and 34.5% to 56.4% at 35°C, whilst the uniformity of the chromium distribution in crust leather was gradually reduced. At the same initial tanning temperature, the shrinkage temperature (Ts) of wet blue tend to increase first and then decrease with the increase of the CTA’s PS, and reached above 100°C when the PS was in a range from 2000 nm-2700 nm. As the PS continues to increase, the inner layer was insufficient tanned due to excessive tanning of surface, leading to a decrease in hydrothermal stability of crust leather.
