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).

Seven different knitted fabrics, which differed in terms of structure and raw material composition (polyester, cotton and cotton/polyester), were printed using the sublimation transfer technique. For the sublimation of cotton/polyester and cotton knitted fabrics, a coating powder was used for paper modification with the aim to bond reactive ink to the natural fibres. The influence of yarn parameters, pattern and the density of knitted fabrics on the degree of changes after the printing process was considered. Smaller changes in structural and physical properties were recorded for polyester knitted fabrics, while major changes in structure were observed in knitted fabrics containing cotton fibres, where were weight gain and reduction in geometrical roughness values. In addition, a significant change in density was recorded for polyester printed knitted fabrics. The parameters that influenced the colour difference results for polyester knitted fabrics were the yarn parameters and the pattern. Significantly high colour difference values were obtained for cotton (from 7.9 to 14.2) and cotton/polyester (from 8.5 to 14.4) knitted fabrics. The main reason for the high colour difference results was the alteration in the structure of the knitted fabrics.

Revisiting the sublimation printability of cellulose-based textiles in light of ever-increasing sustainability issues / Ilhan Özen in COLORATION TECHNOLOGY, Vol. 138, N° 6 (12/2022)  

[article]  inCOLORATION TECHNOLOGY > Vol. 138, N° 6 (12/2022) . - p. 579-692 Titre : Revisiting the sublimation printability of cellulose-based textiles in light of ever-increasing sustainability issues Type de document : texte imprimé Auteurs : Ilhan Özen, Auteur ; Reinhold Schneider, Auteur ; Michael R.

Langues : Anglais (eng) Catégories : Fibres cellulosiques Impression par transfert Impression sur étoffes Transfert par sublimation Index. décimale : 667.3 Teinture et impression des tissus Résumé : Sustainability, being a recent buzzword, has been given an increasing emphasis in all industry fields, especially in the textile industry, since it is one of the main contributing sectors to resource consumption and thus environmental pollution. Among them, coloration of textiles should be paid special attention due to offering enormous savings in terms of sustainability. Within all fibres, cotton, being one of the cellulosic fibres, has been the most widely used material alone or together with poly(ethylene terephthalate) (PET). Therefore, we focus on the coloration of cellulose-based fibres and its blends with PET in this review. There is only one single coloration technique at the intersection of sustainability and coloration, that is, sublimation or heat transfer printing, because it is the most eco-friendly approach for the coloration of textiles. There are many studies on this issue, in which either cellulose, that is, cotton, or the transfer paper is modified/treated. In spite of many attempts for sublimation printability of cotton and its blends with PET, they still have problems in terms of sustainability that limits its applicability. In light of ever-increasing sustainability issues such as Agenda 2030, new developments are yet to be expected for achieving sustainable coloration of cellulose-based textiles and their blends. Therefore, it is high time to revisit the sublimation printability of cellulose-based textiles, to mention the latest developments considering nanotechnological advancements, and to give a future perspective in this field.
