ABSTRACT

This study attempts to disclose the optimum dyeing time for exploiting banana agricultural bio-resource waste for sustainable dyeing of cotton fabric. 100% cotton knitted single jersey commercially scoured-bleached fabric used for this experiment having areal density 175 grams per square meter. Natural dye retrieved from banana floral stem by roller squeezer machine. Selected samples were dyed at 100℃ for 20, 30, 40, 50, 60 and 70 minutes respectively. Effect of time variation were calculated using CIE L*a*b* color space in terms of colorimetric properties of colored fabric viz. color co-ordinates, color strength (K/S), brightness index (BI), degree of color levelness. Color fastness to wash, water, perspiration, rubbing and light were valued for estimating the color durability. Except light fastness property all tested color fastness properties were 3-5 i.e. very good to excellent. For all evaluated parameters samples dyed for 60 minutes exhibited best result. This reports forecast a sustainable technology for effective utilization banana floral stem sap bio-resource waste for coloration of cotton fabric.
