Abstract:
Fabric was traditionally dyed with natural dyes, but after the discovery of synthetic dyes in the year 1856, the usage of natural dyes gradually decline. Today, however, people are increasingly concerned with both, the environment and human health. Natural dyes have more benefits than synthetic dyes. Natural dyes are easily biodegradable in nature, eco-friendly and non-allergic to human skin. The methodology included, bark of the Manilkara zapota plant from which dye can be extracted in acidic, basic, and neutral mediums. Dye extracted from bark of the Manilkara zapota plant were used for dyeing of silk, cotton, and wool fabrics and evaluated. The criteria for evaluation of the best dye colour obtained from bark of the Manilkara zapota plant included visual evaluation, colour strength (K/S) and wash fastness of the dyed samples.
