This work aimed to use chicken feathers wastes (CF) as a natural source of active amino acids after alkali treatments with 0.95N NaOH solution. The soluble feather was analyzed using liquid chromatography amino acid analyzer and applied to both the bleached and mercerized cotton fabrics made from Egyptian cotton varieties namely Giza 89 (G89), and Gin 90 (690) of aop season 2002/2003. The treated and untreated fabric samples were tested for their mechanical properties expressed as the tensile strength N/on², and elongation%. The dyeing behavior expressed as color strength (K/S) using Kubelka-Munk equation, and t.N protection values were also investigated. The fixation of CF on the cotton fabric was done by the padding of CF solution onto fabrics followed by dry-cure process. The factors affecting the fixation processes were systematically studied. The finished fabrics show higher tensile strength, more dyeing uptake, more reduction of the UV transmitted, and higher fastness properties (far wash, light, and perspiration) as compared to the untreated samples.
