Pretreatment with oxygen plasma significantly improved the hydrophilicity and tensile strength of all tested samples and showed that oxygen plasma can improve K/S , washing fastness, and even replace certain mordants in wool dyeing with natural pomegranate dye. All dyed samples exhibited good antibacterial activity against Staphylococcus aureus , which can be contributed to the phenol content in pomegranate dye. Only after 28 days of intensive ageing in natural weathering conditions did K/S and antibacterial activity against Klebsiella pneumoniae slightly decrease in dyed samples pretreated with oxygen plasma.

Research of influences of surface structure of coloured textiles : applying fuzzy logic / Martinia Ira Glogar in COLORATION TECHNOLOGY, Vol. 127, N° 6 (2011)

[article]  inCOLORATION TECHNOLOGY > Vol. 127, N° 6 (2011) . - p. 396-403 Titre : Research of influences of surface structure of coloured textiles : applying fuzzy logic Type de document : texte imprimé Auteurs : Martinia Ira Glogar, Auteur ; Djurdjica Parac-Ostermann, Auteur ; Darko Grundler, Auteur ; Tomislav Rolich, Auteur Année de publication : 2011 Article en page(s) : p. 396-403 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Coton Le 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). Logique floue Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : The fuzzy logic-based approach was applied in studying the influence of a different textile surface structure on colour appearance and similarity. The fuzzy-based approach has been chosen because fuzzy logic provides the computerising of human reasoning. For the analyses, 100% cotton samples with certain characteristics were chosen. First, the computer match prediction was performed to determine the concentrations of dyestuff to be used in the experimental work. A yellow-shaded direct dyestuff suitable for cotton dyeing was used. In the next step, the fuzzy logic system was created based on terms that would define the surface characteristics of the samples. The most important part was a proper definition of the rules and linguistic variables that use words for assigning the values of properties and that influence the experience of an observer (gloss, smoothness, roughness, etc.) and connect input space with output space. Finally, the performances of both systems were compared and analysed. In this work, the approach was based solely on the surface–structural characteristics of textile samples. The main aim was to examine the approach using the fuzzy logic-based technique in order to provide the method that would include surface parameters of textile samples that are of importance in applying colour to different structured textile surfaces. It was confirmed that the fuzzy logic reasoning would have its application in the control of the influence of the surface structure of coloured textiles, especially for lighter shades where the influence of structure parameters on the colour experience of an observer is more emphasised.
