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).

PolysaccharidesLes polysaccharides (parfois appelés glycanes, polyosides, polyholosides ou glucides complexes) sont des polymères constitués de plusieurs oses liés entre eux par des liaisons osidiques.
Les polyosides les plus répandus du règne végétal sont la cellulose et l’amidon, tous deux polymères du glucose.
De nombreux exopolysaccharides (métabolites excrétés par des microbes, champignons, vers (mucus) du ver de terre) jouent un rôle majeur - à échelle moléculaire - dans la formation, qualité et conservation des sols, de l'humus, des agrégats formant les sols et de divers composés "argile-exopolysaccharide" et composites "organo-minéraux"(ex : xanthane, dextrane, le rhamsane, succinoglycanes...).
De nombreux polyosides sont utilisés comme des additifs alimentaires sous forme de fibre (inuline) ou de gomme naturelle.
Ce sont des polymères formés d'un certain nombre d'oses (ou monosaccharides) ayant pour formule générale : -[Cx(H2O)y)]n- (où y est généralement x - 1). On distingue deux catégories de polysaccharides : Les homopolysaccharides (ou homoglycanes) constitués du même monosaccharide : fructanes, glucanes, galactanes, mannanes ; les hétéropolysaccharides (ou hétéroglycanes) formés de différents monosaccharides : hémicelluloses.
Les constituants participant à la construction des polysaccharides peuvent être très divers : hexoses, pentoses, anhydrohexoses, éthers d'oses et esters sulfuriques.
Selon l'architecture de leur chaîne, les polysaccharides peuvent être : linéaires : cellulose ; ramifiés : gomme arabique, amylopectine, dextrane, hémicellulose et mixtes : amidon.

Soie et constituantsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Dry transfer technology involving adhesion and steaming was designed for the printing of untreated silk and cotton with reactive dyes. The transfer paper was prepared by coating mixed polysaccharide thickeners composed of adhesive high‐substituted hydroxypropyl cellulose (H‐HPC) and another thickener, either sodium alginate (SA), carboxymethyl cellulose (CMC), hydroxyethyl cellulose (HEC), guar gum (SG‐9) or carboxymethyl starch (SG‐24). Patterns on the transfer paper were obtained by means of ink‐jet. The thermal plasticity of H‐HPC was observed and 120 °C was determined as the adhesion temperature. Rheological testing of all the thickeners verified that their shear‐thinning behaviour favoured successful coating. By comparing the effects of different mixed thickeners on the prints’ quality with regard to colour depth, sharpness, colour fastness and handle, it was concluded that the colour depth depended on the adhesion extent and reactivity between the thickener and reactive dye. Using H‐HPC/SA and H‐HPC/HEC produced the highest and lowest colour depths, respectively. The sharpness was visibly influenced by the different mixed thickeners. A clear pattern was achieved when the other thickener was CMC, SG‐9 or SG‐24. Both the colour fastness and handle were desirable, irrespective of the mixed thickeners used.

Membranes échangeuses d'ionsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The adsorption and desorption performances of CI Acid Red 18 and CI Acid Red 88 on an anion exchange membrane were studied. The effects of temperature, time, pH value and inorganic salt on the adsorption were investigated. The results showed that temperature and pH value had nearly no influence on the dye adsorption. The addition of inorganic salt (sodium sulphate) in the dye solution had a definite influence on the adsorption. The adsorption of the two acid dyes was in accordance with the pseudo-second order dynamics model. The Langmuir adsorption model could describe the adsorption processes well. The membrane was more effective on CI Acid Red 18, which has three sulphonic groups. In the desorption process, different solutions were applied to investigate the desorption performance of the two acid dyes. The desorption percentage could reach ca. 90% using a mixture of ethanol, sodium chloride and water as the desorption solution. The anion exchange membrane could be reused.

ViscositéIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This paper is concerned with the quality of lines and disperse ink in printing patterns on different untreated polyester fabric constructions. The lines running in the weft and warp directions were printed on polyester fabric constructions, and printing accuracy was assessed. Ink spreading is one of the important factors that influences the ink distribution. Thus, in order to acquire satisfactory ink-jet printing products, it is essential to control the spreading of ink on the polyester fabric. To meet these conditions, a series of chemicals (disperse dye 5.01 wt%, PVP-K30 0-2 wt%, DEG 5-20 wt%, water 64.17-79.17 wt%, etc) with different mass fractions was used to prepare disperse ink. The jetting behaviour of ink was related to its surface tension and viscosity, which was characterised by an automatic surface tensiometer and rotational viscometer. Line profile was used to evaluate the printing effect. Low field nuclear magnetic resonance and three-dimensional super depth digital microscopy were used to reveal the relationships between the state of water, ink diffusion behaviour and printing sharpness. The results showed that increasing ink viscosity or decreasing free water content is advantageous to improve the sharpness of the printing pattern. The effects of fabric structural parameters on line image quality are discussed. The printing quality was closely related to the weight and structure of fabric. The heavy weight fabrics had accurate print pattern sharpness. The fastness test results showed that the ink printing pattern had good colour fastness.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Microbial dyes have received substantial attention because of their natural environmental protection, simple access, and reduced regional and seasonal restriction. In this work, a microbial dye, the yellow pigment produced by Metarhizium anisopliae, was first studied then applied. The strain produced by the culture was identified, and the conditions for producing yellow pigment were optimised. Further, the stability of M. anisopliae yellow pigment was examined, and the pigment was applied to the dyeing of silk and wool fabrics. The results showed that the homology of the strain with M. anisopliae was 99.98%. In liquid fermentation culture, the optimal carbon source was glucose, and the dosage was 30 g/l. The maximum pigment yield can be obtained by culturing with 4% v/v of inoculation quantity at pH 7 and 30 °C. In addition, the effects of pH, temperature and metal ions on the yellow pigment of M. anisopliae were significant. The optimum dyeing process conditions were dyeing temperatures of 80 °C for silk and 90 °C for wool, with a dyeing time of 60 min. This research developed a novel microbial dye and studied its application for the dyeing of protein fibres.
