| Abstract | ||||
| Natural dyes are gaining great attention as eco-friendly alternatives to synthetic dyes for textile applications. In this study, methanolic extracts of olive (Olea europaea L.) and ziziphus (Ziziphus spina-christi L.) leaves were mixed in a 75–25 ratio and used as natural dyes for cotton fabrics for the first time. To identify the chemical constituents present in the major extract, we performed ultra-performance liquid chromatography-mass spectrometry (UPLC‒MS/MS). The color fastness and characteristics of the dyed fabrics were evaluated by spectrophotometry and standard methods. The results showed that the olive-ziziphus leaf extract mixture produced a yellowish-brown color on cotton with good light, washing, and sweat fastness. This study demonstrated the potential of olive and ziziphus leaves as eco-friendly sources of natural dyes for cotton dyeing. | ||||
