The extraction from orange peel using the pad-dry-technique has been used as natural dye for cotton fabrics. In the current study, fabrics made from extra long Egyptian cotton of Giza 93 were dyed with the color extracted. The study was conducted in progressive stages to obtain how orange peel was to be used as the selected natural dyes. The factors affecting the fixation of the extracted dye with cellulose was studied. The treated and untreated fabrics samples were tested for their mechanical properties expressed as tensile strength (kg/force) and elongation%. Dyeing performance in terms of color parameters (K/S, L*, a*, b*, Chroma, hue and ?E), and fastness properties (wash, perspiration, and light fastness) were studied. The samples show high tensile strength, high color strength, and high fastness properties. These results are very important for industrial application with the production of a natural dye as an inexpensive source from orange peel as a by product. The ideal padding parameters for a given dye concentration, improving the dye uptake may be employed, potential for additional benefits from such improvement techniques and the feasibility of a coloring process that uses chemicals with a lower environmental impact as compared to current practices.
