Abstract:
The use of natural dyes and natural finishes on textiles has become a matter of importance because of the increased environmental awareness to avoid hazardous synthetic dyes (soluble and Non water soluble) and synthetic chemicals. The objective of this study is to dye Banana fiber with myrobalan natural dye for comparative analysis of colour efficiencies (K/S), CIE L*a*b* values and the colour fastness properties. Pre-mordanting and post-mordanting of banana fiber were carried out using alum, stannous chloride and ferrous sulphate mordants. Results were achieved for dyeing at 90 °C for 60 min at 10%, 30% and 50% concentration of the dye on the weight of fabric using pre- and post-mordant dyeing techniques. Treated fiber showed a substantial increase in colour depth (K/S) and adequate wash, light and rubbing fastness properties with mordanted dyed banana fiber.
