Langues : Anglais (eng) Catégories : Colorimétrie 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).

Currently, the widely used dyeing recipe prediction methods based on colour tri-stimulus cannot effectively avoid the metamerism phenomenon. An intelligent dyeing recipe prediction model for cotton fabric dyeing is proposed in this paper based on hyperspectral colour measurement and a deep learning algorithm. The hyperspectral colour measurement can obtain three-dimensional spectral information (X, Y and λ) of fabric samples, and can acquire accurate colour values even with uneven samples if the regional correlation algorithm is used. A deep learning algorithm based on an improved recurrent neural network was then employed to establish the model between spectral reflectance and the dyeing recipe. In total, 343 evenly dyed and 20 unevenly dyed fabric samples were dyed using the dyestuffs of Reactive Red CI 238, Reactive Blue CI 204 and Reactive Yellow CI 206, upon which the recipe prediction model was based, established and evaluated. The experimental results show that the proposed model based on hyperspectral colour measurement and our algorithm can provide higher prediction accuracy for Reactive Red CI 238, Reactive Blue CI 204 and Reactive Yellow CI 206. The relative prediction errors are 3.40%, 2.70% and 3.10%, respectively, for these three types of dyeing recipe, while the relative prediction errors are 19.60%, 22.60% and 11.83%, respectively, using the Datacolor 650 recipe prediction model.
