Present research on pollution free dyeing and mordanting is indicated as a creative innovation of textile coloration on cotton fabric in which natural dyes were extracted from Swietenia macrophylla (Mahogany leaf) and Musa acuminata (Green Banana Pill) as an unpolluted dyes and Citrus. limon (L.) juice was applied as an unpolluted natural mordanting agent. There is no synthetic chemical was used during the whole progression in dyes extraction process and dyeing method. Both the treated and untreated fabric samples were tested for their dyeing performance in terms of color strength, K/S value and color fastness properties like color fastness to washing, rubbing and light. Higher K/S value of lemon mordanted sample was investigated by analysis of spectrophotometer for both dyeing with mahogany and green banana pill. Color fastness to washing and rubbing had been found moderately good for both dyeing with mahogany leaves and green banana pill with lemon mordanting. Moderately good color fastness to light had been found for dyeing with only mahogany leaves and green banana pill but improved light fastness was found for green banana pill with lemon mordanting. As per visual appearance, dyed fabric with green banana pill and lemon mordanting was found very even distribution of color on the surface of cotton fabric. An exceptionally attractive soft hand fell and color shading outcome was observed for dyeing with green banana pill comparing to mahogany leaves without having any additional application of synthetic softner which is the demand of both local and foreign customers in clothing industries.
