Ozonation
Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This work has focused on the use of ozonation in order to improve the dyeability of mohair fibres. The study was carried out using a known concentration of ozone and involved process parameters such as wet pick-up, level of pH and treatment time. The effect of fibre ozonation was assessed in terms of colour, and test samples were also evaluated using scanning electron microscopy and Fourier transform–infrared spectroscopy. The optimum conditions of the ozonation process were determined as 60% wet pick-up, pH 7 and 30 min. According to the experimental results, it can be concluded that ozonated mohair fibres can be dyed both at 90 and 80 °C with all dye classes without causing any decrease in colour yield. Dyeing kinetics and thermodynamics were also studied and it was demonstrated that the rate constant and the standard affinity of the ozonated sample increased.

Traîtements de surfaceIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Wool is a natural biopolymer with special properties, including warmth retention and skin-friendliness. However, its application in the textile industry is limited by the scale layer that covers its surface, which prevents the efficient diffusion of dye into the interior of its fibres, and increases wool's susceptibility to shrinkage during washing. Here, dissolution with sodium bisulphite is used for wool surface modification. The properties of surface dissolved wool are comprehensively characterised, including strength loss, shrinkage rate and dyeability. The three-dimensional images indicated that scale layer was etched. Coupled with Fourier-transform infrared (FTIR) spectra, the test results of strength loss and shrinkage rate indicated that surface dissolution degree can be controlled by time and temperature, and that the process does not break the fibre's main body structure. Dyeability properties, including dye absorption rate, deepness and uniformity at a lower temperature were enhanced, indicating amenability to industrial production. Our findings highlight a novel, efficient method of modifying protein fibre surface for enhancing properties with potential for large-scale application.

Colorants dispersésCatégorie de colorants très peu solubles dans l'eau, utilisés à l'origine comme colorants pour l'acétate, et qui généralement sont appliqués sous forme de suspensions aqueuses de faible concentration.Les colorants dispersés sont largement utilisés dans la teinture de la plupart des fibres manufacturées, surtout le polyester.

Oxydants
Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Disperse dyes are not currently applied to wool commercially, in large part because of inadequate wash fastness, but they do have potential, especially for wool-polyester blends. In this study, for the first time hydrogen peroxide was investigated to increase the wash fastness of disperse dyes on wool. In the absence of oxidants, 10 disperse dyes from seven classes imparted colours with a range of depths (K /S 2-26) with wash fastness (grey scale ratings for colour change) grades of 3 to 4-5. Hydrogen peroxide had only small effects on colours and gave only small enhancements to wash fastness, which were limited to anthraquinone, nitrodiphenylamine, disazo and coumarin dyes. The bleach activators Prestogen W and citric acid enhanced the bleaching effect of hydrogen peroxide but did not assist with raising wash fastness. Hydrogen peroxide in post-dyeing scouring made the dyeings brighter but did not significantly enhance wash fastness. Ammonium persulphate, which was included for benchmarking with earlier studies, yellowed the wool and decomposed some dyes. This study extends the range of dye classes whose wash fastness on wool can be improved by ammonium persulphate to now include diazo, coumarin and methine, and confirms that oxidants/free radical initiators have potential for enabling the disperse dyeing of wool.

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

Traitement chimiqueIndex. décimale : 668.4 Plastiques, vinyles Résumé : Because of their appealing properties, such as biodegradability, high basic stiffness, low density, and low cost, natural fibers have begun to be used in a variety of applications. In comparison to synthetics, they are also reusable. The aim of this work is to develop new woven materials made of wool and Alfa fibers (Stipa-tenacissima). The extraction of Alfa fibers was achieved via alkaline treatment. The chemical composition, mechanical and physical properties of the extracted fibers were determined. Wovens were produced using the weaving of taffetas technique. This study presents a chemical, physical, morphological and mechanical characterization of Alfa/wool yarns and fabrics. The results show that the fabric made of fibers treated with 2 mol concentration of NaOH presents the greatest morphological structure and a higher degree of crystallinity due to the reorganization of the molecular chains that results in a better orientation of the fibers compared to other concentrations. On the other hand, the results of the tensile test show that the Young’s modulus of the Alfa/Alfa woven fabric is 8 ± 1.157 MPa in the weft direction, compared to the Alfa/wool woven fabric which has 6.06 ± 0.196 MPa and wool/wool woven fabric with 14.10 ± 1.369 MPa.
