Abstract:
The major development in textile manufacture is fabric coloration. Such as natural colorants are mostly known for practice in dyeing for fibers like wool, cotton and silk even for leather coloring meanwhile pre-historic times. The natural bases are eco-friendly, obtainable at low cost, non-allergic, at liberty of azo-compounds and biodegradable. In this research, dye stuff was extracted from (Allium cepa) Onion skin and used for dyeing natural fabric with natural and synthetic mordants application. As onion is a remedial root plant and onion skin is deliberated as waste material from kitchen, which is used for fabric and food coloration. Natural mordants give pale colors, whereas synthetic mordants give yellow color. Shade depth with spectrometer was determined to check the K/S value. Washing test was applied to evaluate the fastness of color and tensile strength was applied on samples to measure the strength after dyeing. While rubbing test in dry as well as wet condition was applied to check the color fastness to abrasion. There was assessment of physical assets of fabric once using extracted dye of natural source.
