PeroxydaseUne peroxydase, souvent écrit abusivement peroxidase comme en anglais1, est une enzyme de type oxydase qui typiquement catalyse une réaction de la forme : AH2 + H2O2 → A + 2 H2O - ROOR' + donneur d'électron (2 e−) + 2H+ → ROH + R'OH.
Les peroxydases sont les enzymes parmi les plus universelles du monde vivant. Dans l'organisme, les peroxydases décomposent notamment les composés peroxydes, toxiques.
En chimie et biochimie, les peroxydases sont très utilisées comme objet d'étude et réactifs pour des synthèses. La peroxydase de raifort (HRP) est notamment largement utilisée en biotechnologie comme réactif de détection dans les immuno-essais.
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 textiles
Textiles et tissus -- LavageIndex. décimale : 667.3 Teinture et impression des tissus Résumé : An enzyme-based textile coloration process using peroxidase (EC1.11.1.7) was investigated for its potential as an alternative to conventional textile dyeing processes, with the benefits of being low in energy use and non-damaging to fibres. The current study presents a process for the coloration of wool fabric using peroxidase oxidation of a range of different aromatic compounds in the presence of hydrogen peroxide. The results revealed that wool can be successfully dyed by peroxidase-catalysed coloration at temperatures as low as 30°C. By controlling the pH values and buffer systems during processing, a diverse colour palette was produced, depending on the small molecular aromatic compound used as the precursor. Colour fastness testing found that fastness to washing, rubbing and light properties achieved good to excellent ratings, with further improvement to wash fastness provided by a post-soaping wash. No fibre damage occurred due to peroxidase-catalysed coloration. This enzyme coloration process is a promising alternative to conventional wool dyeing processes with the advantage of effective dyeing at low temperatures, therefore having the potential of reducing energy consumption and preventing fibre damage.

ViscoseIndex. décimale : 677.4 Textiles artificiels Résumé : Wet treatment post-fiber processing such as dyeing, finishing and function-alization of fabrics results in the generation of a large amount of effluents of dyes and chemicals, creating an adverse impact on the environment and human health. Imparting the coloration and functionalization during the process of making the fiber itself is an effective solution practiced in the synthetic and regenerated cellulosicfiber industry to reduce this impact, e.g. dope dyeing, adding cationic dyeability etc. The challenges involved in the case of fiber level modifications in regenerated cellulose process like viscose are different from those encountered in synthetic fiber processes. Though commercial products based on fiber modifications are available, a gap exists in the understanding of additives — media interactions in the viscose process. This study has been initiated to bridge the gap and enable better processability and product quality in products made through fiber modification. In this specific article the focus is on pigment-slurry/dope interactions, during the process of making dope dyed viscose fibers.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : In this study, a novel system utilising ozone in jet dyeing machines is introduced, and the results of ozone-clearing treatments of disperse dyed polyester on the prototype modified machine are reported. A Venturi injector was mounted on the liquor circulation pipe of the jet dyeing machine to feed ozone gas into the machine. Ozone was generated via an ozone generator by feeding conditioned air into the generator. The ozone gas entering the pipe partly dissolved in the treatment liquor; the dissolved portion and the gaseous ozone interacted via the fabric in the pipe, especially in the nozzle and also at the bottom of the autoclave (machine body). Disperse dyed polyester fabrics of textile-company mass production were ozone cleared in this prototype. Ozone clearing was achieved in cold water (room temperature), and no other chemicals were used. The colour of the samples, wet fastness properties, and the chemical oxygen demand of the effluent were investigated, and costs were compared with those of conventional reduction clearing of ozone. Results were outstanding: an 83% cost reduction, 67% timesaving, and an 88% COD reduction were achieved. Note de contenu : - Colour differences of the dyed fabrics

Chimie textile
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).

Urée -- DérivésIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This study aimed at developing a model for predicting the crease recovery performance and tear strength of cotton fabric using modified N-methylol dihydroxyethylene urea, polyethylene softener, catalyst, curing time and curing temperature as the predictor variables. A quarter factorial design was constructed and, based on the experimental results, regression models were built to predict crease recovery angle and tear strength of the treated fabric. All experimental design and statistical analysis steps were implemented, using Minitab statistical software.
