Özet
<p>Natural dyestuffs derived from various plants can be used for dyeing processes in the</p><p>textile and leather industries. Hibiscus sabdariffa, one of these natural dyestuffs, is known to be used</p><p>in textiles and produces a red color with good dyeing properties. This study aimed to investigate the</p><p>dyeing effect of Hibiscus sabdariffa flower on leather materials and to determine its dyeing</p><p>properties. To achieve this, a dye was extracted from Hibiscus sabdariffa, and all wet processes of</p><p>ostrich skins—an exotic type of leather—were carried out, incorporating the dye extract by adding a</p><p>mordant during the dyeing process. Both chrome and vegetable tannins were utilized to examine the</p><p>effects of the tanning process. Extraction yield, pH measurement, color measurement, to-and-fro</p><p>rubbing fastness tests, and dyestuff exhaustion measurements were conducted. The results indicated</p><p>that, particularly when the post-mordant process was applied, the extracted dyestuff yielded superior</p><p>dyeing properties and color results compared to the non-mordant process. The extract from Hibiscus</p><p>sabdariffa was determined to effectively dye the skins, producing beautiful and satisfying colors,</p><p>especially when using iron sulfate mordant in vegetable-tanned leathers.</p>
