Abstract :In this research, the dyeability of wool fabrics by using olive oil production waste was investigated. In this study, olive oil wastes were separated into two components as olive oil wastewater and pomace by filtration method. 100 % wool fabrics were dyed with conventional method with olive oil wastewater. In addition, the pre-mordanting method was preferred as the mordanting method. Alum, ferrous sulphate, tannic acid and tartaric acid were used as mordant materials, and various mordant concentrations and different mordant durations were studied. In dyeing, 100 % olive oil wastewater was used as dyeing liquor and all dyes were dyed in 1:20 liquor ratio. Color analyses of dyed fabrics were made, CIEL*a*b* and K/S values were examined. In addition, the coloring agents in olive oil wastewater were investigated by HPLC analysis. Light fastness, washing fastness, wet and dry rubbing fastness, acidic and alkaline perspiration fastness and water stain fastness were investigated.
