Plantes tinctorialesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : An environment-friendly, non-toxic, red-dyed leather was developed using four naturel dyes -cochineal, lac, beet red, and monascus. The affects of the dye concentration, dyeing time, and temperature on the light fastness, rubbing fastness, colour difference, and K/S values (i.e., each dyed sample's apparent depth value) were investigated to find the hast natural dye for eco-dyeing the Ieather. When dyeing the leather red, the K/S value generally increased as concentrations of cochineal, monascus, lac, or beet red dyes were increased. However, the increase in the K/S value was substantially lowered when more than 5.0% o.w.l. (on the weight of Ieather) was used, indicating that the optimal dye concentration is 5.0 % o.w.l. A dyeing Urne of 100 minutes was found to be optimal because the K/S value stabilized aller 100 minutes. The use of cochineal 5.0 % o.w.l. resulted in a 9.18 RP (plum) and the use of lac 5.0 % o.w.l. resulted in a 9.52 RP. These resuits indicate colours that were the closest to red. Their ?E* values, which were the levelling property indicators of the leather, were 0.56 and 0.13, respectively, showing superior characteristics compared to the other two dyes.

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).

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Because of the environmental burden of synthetic dyes, there has been a revival in practising natural dyeing globally. Natural dyeing uses metallic mordants for improving the dye's fastness properties. However, metallic mordants are also toxic. Herein, both the dyes and mordants were extracted from plant waste using water as a green solvent. The extracted dyes were then applied to the cotton fabric using a natural mordant. The dyed fabric samples were characterised for colour yield, fastness properties, ultraviolet protection and antibacterial activity. For the intended purpose, the wastes of sugarcane bagasse, wheat bran and rice husk were used for dye and mordant extraction. It was found that by increasing the extraction temperature from 30 to 60°C, the dye yield increased. From the K/S values, it was observed that premordanting gave better colour strength than post-mordanting or meta-mordanting. The overall ratings for washing and crocking were 3-4 and 4-5, respectively. No significant antibacterial activity was observed in the dyed samples. However, excellent ultraviolet protection was observed.

Résistance au lavageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The resurgent interest in leather and wool clothing has led to developments in brilliant colours with different shades on leather and wool that hold promise for re-opening this market for the two substrates. It is necessary to use more than one class of dyestuff under variety of conditions in this work and to modify the two components before printing. Fibre reactive dyes with three different reactive groups, mono-chloro triazine (Cibacron Yellow P6GS), dichloro-triazine (Procion Red MX-5B) and vinyl sulphone (Remazol Brilliant Orange FR), were used to print both unmodified and modified, i.e. cationised leather and wool substrates using Tenofix Extra ECO and Solfix E cationic reagents. Pre-cationisation of leather and wool brings about an improvement in the depth of the prints as well as in washing and light fastness properties.
