Abstract
The aim of this study is to determine the dyeing temperature at which cotton fabrics will absorb the most sodium copper chlorophyll (SCC) dyestuff. Bleached 100% cotton rib knitted fabrics were dyed with SCC at different times without mordanting. The dye absorption of the fabrics was determined by a spectrophotometric method depending on the dyeing time. Firstly, SCC solutions with known concentrations were measured and the calibration (absorbance-concentration) curve was obtained. Then, the SCC concentrations remaining in the dye liquors after dyeing at different times were determined. The dye exhaustion of the fabrics was calculated using the concentrations of the dye baths before and after dyeing. Color measurements and fastness tests of the dyed samples were performed.
