| Abstract | ||||
| using natural dyes on textile materials has become more popular over the past years, maybe as a result of increasing demand for a green environment and decreased pollution of synthetic dyes., this study investigated the use of coffee to extract colors for dyeing wool fabrics using the heating method. Colorant was extracted from coffee using different concentrations at different times for different temperatures. Measurements have been done on the dyed samples and the fastness properties of samples dyed with coffee. Mordant copper sulfate, ferrous sulfate, and Aluminium sulfate were used to increase the color fastness of dyed wool samples. The samples were affected by some factors such as dye extraction, dye concentrations, temperature, pH values, and the time of dyeing. K/S was measured for dyed wool fibers. The fastness properties such as washing, rubbing, perspiration, and light of dyed fibers were measured. | ||||
