Studies of antibacterial properties of banana fabric by dyeing with natural dyes

Abstract

Natural fibres, which are always biodegradable, organic, and non-toxic, find wide demand in technical textiles. Banana, a cellulosic fibre acquired from the banana plant, is a natural fibre that contributes to conserving the environment. The present study envisages extracting banana fabric using natural dyes such as henna, turmeric, and indigo. The banana fabric was pre-mordanted with two types of mordants, i.e., copper sulphate and alum. The banana fabric was dyed with turmeric, henna, and indigo. The henna shows a brown colour, the indigo shows a light blue colour, and the turmeric shows a rich yellow colour. Among those three dyes, turmeric shows the best colour, i.e., a rich yellow colour, and it also shows good antibacterial properties.
