SoufreIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Chamois leathers find application in fuel filtration and cleaning. Recently, use of chamois leathers is explored in the development of sports garments, gloves and other personal wear. However, one of the consumer demand viz. different colors on the end product is not met by chamois leathers. Hence, dyeing is essential to make it more attractive for end user applications. In the present work an attempt has been made to develop colored chamois leather by employing water soluble sulphur dyes. The offer of sulphur dyes have been optimized based on dyeing characteristics, color fastness and color values. The results indicate that offer of 1 and 2% of the dyes show better colour value and fastness to rubbing. Hence, it could be inferred that coloring of chamois leathers not only improved the aesthetic appeal but also helped in adding value without altering inherent properties of chamois leather.

Vêtements en cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : For several years the consumer appetite for fashion apparel leathers has been growing steadily. Tanners are forced to produce an enormous range of different shades and types of leather in small lots within a very short time to satisfy retail demands. Of course, classical black dyed leathers are still in fashion, but the growing demand for coloured leathers, especially in very brilliant shades with high fastness levels, creates serious challenges for the tanners and the dye manufacturers.

LiposomesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : CI Acid Black 210 was microencapsulated into liposomic systems, and the effects of the microencapsulation on dyebath exhaustion, depth of shade, colour fastness properties and through-dyeing of chrome-tanned leather were studied. In comparison with the original dyestuff form, the microencapsulated dye showed a deeper shade and a greater depth of through-dyeing. Exhaustion and colour fastness values were the same.

A chrome free aldehyde and aluminum tanning system was used to prepare the leather for the dye experiments. For the dye preparation experiments gallnut and sappan wood, which are representative polygenetic natural dyes, were extracted by alcohol extraction; then decompressed and refined under concentrating conditions to produce dye in powder form. To produce natural dyed leather with a black color, 5% gallnut and sappan wood were used and the mordant agent, iron mordant (FeSO4·7H2O) at 1% of the leather weight, was applied in three different sequences. Applying the mordant simultaneously produced a superior result compared to it application before or after the application of the natural dye. To evaluate the softness and color change of leather, an anionic fatliquor agent was used at 12% of the leather weight. An excellent dark black color and chroma was obtained on the leather surface as a mordant agent and complex compound. The excellent results obtained during the evaluation of rubbing fastness, K/S (coloring matter concentration of surface), and color difference enabled the conclusion that leather with a deep black color could be manufactured with this method.

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.
