| Résumé : |
Cow wet blue stock was colored with solubilized sulfur dyes in a systematic study to unravel the color yield quality of dyeing and fastness of the dyes. These dyes penetrated the leather cross-section well and this performance resulted in a beneficial tone-in-tone dyeing, which means that the color of the grain, flesh and cross section of leather was almost the same tone. The levelness and uniformity of dyeing were excellent. Their fastness performance was generally very good. The resultant shades suggested that the sulfur dyes were best suited for light, pastel and medium shades, which require a high degree of levelness, penetration and fastness properties. An intense shade resulted from offering the sulfur dyes ahead of the retanning and fatliquoring process steps with a trivial reduction in penetration through the leather cross section for all the ten dyes studied. These findings favor the profitable production of light, medium to dark dye shades on leathers. |
