Plasma à pression atmosphériqueUn plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère.
Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse.Index. décimale : 667.3 Teinture et impression des tissus Résumé : In this article, the performance of atmospheric pressure plasma treatment in the desizing of grey cotton denim fabric followed by an enzymatic colour fading process was studied. Four atmospheric pressure plasma processing parameters, namely, treatment time, ignition power, reactive gas (oxygen) concentration and jet distance were considered for desizing. In order to investigate the optimum conditions (based on weight change) for atmospheric pressure plasma treatment, an orthogonal array testing strategy was used. The optimum conditions for atmospheric pressure plasma treatment in this study were: treatment time, 5 s/mm; ignition power, 160 W; oxygen concentration, 1%; and jet distance, 3 mm. The level of importance of atmospheric pressure plasma processing parameters based on the orthogonal array testing strategy analysis was in the order: jet distance > ignition power > oxygen concentration > treatment time, and the effect of each processing factor is also discussed. In addition, the desizing effect induced by atmospheric pressure plasma treatment was compared with conventional enzyme desizing treatment. The resultant performance properties were also compared. After conducting desizing with atmospheric pressure plasma treatment, the cotton denim fabric was subjected to an enzymatic colour fading process. The colour fading effect was found to be more significant when compared with the conventional enzymatic colour fading process.

Titre : Effect of enzyme treatment and dyeing on the mechanical properties of linen Type de document : texte imprimé Auteurs : C. W. Kan, Auteur ; C. W. M. Yuen, Auteur ; Y. L. Lam, Auteur Année de publication : 2009 Article en page(s) : p. 269-276 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : In this paper, different concentrations of cellulase enzyme were used for treating linen fabrics. The pretreated linen fabrics were dyed using a bifunctional reactive dye at various concentrations. The effect of enzyme treatment, together with the dyeing process on the low-stress mechanical properties of the linen fabric, was then investigated. The low-stress mechanical properties were assessed quantitatively, including the tensile, shearing, bending, compression and surface properties of the enzyme-treated and dyed linen fabrics. The results revealed that the enzyme treatment with subsequent dyeing could alter these properties to a greater extent, depending predominantly on the concentration of enzyme used.

Choi, Auteur Année de publication : 2007 Article en page(s) : p. 267-270 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Following on from previous research, the possibility of using chitosan in preparing the pretreatment print paste for textile ink-jet printing was investigated but the final colour was not as good as expected. In this study, chitosan was applied separately on cotton fabric for ink-jet printing. A two-bath method was proposed and it was confirmed that a better colour yield was achieved with this method. However, the use of chitosan reduced the tensile strength of the ink-jet printed fabric slightly.

NickelLe nickel est un élément chimique, de symbole Ni et de numéro atomique 28.
Le nickel est un métal blanc argenté qui possède un éclat poli. Il fait partie du groupe du fer. C'est un métal ductile (malléable). On le trouve sous forme combinée au soufre dans la millérite, à l'arsenic dans la nickéline.
Grâce à sa résistance à l'oxydation et à la corrosion, il est utilisé dans les pièces de monnaie, pour le plaquage du fer, du cuivre, du laiton, dans certaines combinaisons chimiques et dans certains alliages. Il est ferromagnétique, et est fréquemment accompagné de cobalt. Il est particulièrement apprécié pour les alliages qu'il forme.
PolyestersIndex. décimale : 667.9 Revêtements et enduits Résumé : Properties of electroless Ni–P plated polyester fabric mainly depend on the plating bath constituents/conditions. The effects of NiSO4 concentration of the plating bath on the deposition rate, phosphorus content, surface morphology, and crystal structure of the electroless Ni–P plated polyester fabric were investigated. The study revealed that phosphorus content in the deposits decreased at higher NiSO4 concentration. SEM micrographs showed that nodule size of the Ni–P deposits increased. All the Ni–P deposits had an amorphous structure. The electromagnetic interference (EMI) shielding effectiveness (SE) of electroless Ni–P plated polyester fabric was evaluated. With the rise of nickel ion in the solution, the EMI SE of the Ni–P plated polyester fabric increased. Note de contenu : - Deposition rate

Titre : A study of the properties of ink-jet printed cotton fabric following low-temperature plasma treatment Type de document : texte imprimé Auteurs : C. W. M. Yuen, Auteur ; C. W. Kan, Auteur Année de publication : 2007 Article en page(s) : p. 96-100 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : This paper studies the effect of low-temperature plasma treatment on an ink-jet printed cotton fabric. Due to the specific printing and conductivity requirements for ink-jet printing, not all conventional printing chemicals, such as sodium alginate and urea, used for cotton fabric can be directly incorporated into the ink formulation. As a result, the cotton fabric requires pretreatment with the printing chemicals prior to the stage of ink-jet printing. Cotton is pretreated with the printing chemicals by means of a coating method. The aim of this paper was to study the possibility and effectiveness of applying low-temperature plasma treatment to enhance the performance of pretreatment paste containing sodium alginate so as to improve the properties of the ink-jet printed cotton fabric. Experimental results revealed that a low-temperature plasma pretreatment coupled with the ink-jet printing technique could improve the final printed properties of cotton fabric.
