| Abstract | ||
| Natural dyes were extracted from marigold flowers, onion outer skins, fenugreek seeds, and green coffee, and were used to color 100% Giza 86 cotton fabric using alum as a mordant. The dyeing process was conducted using three techniques: conventional, microwave, and infrared radiation. The surface properties of the cotton fabric were evaluated using FTIR spectroscopy. Additionally, the dyed fabrics were assessed for color strength (K/S) and fastness properties including washing, light, rubbing, and perspiration fastness. The results indicated a moderate affinity between cotton fabric and the extracted dye. The use of metal mordant improved dye exhaustion in alum-dyed cotton fabrics. There was a significant variation in color shade depth among the different natural dyes. Specifically, marigold extract resulted in a significantly darker yellow shade, while green coffee extract yielded a lighter yellow hue. The dye derived from marigold flowers demonstrated exceptional efficiency in color fastness tests, with the microwave dyeing process yielding the best results for (K/S). However, the use of green coffee and fenugreek in dyeing resulted in superior fastness compared to other methods. | ||
