dyeing of wool using conical prickles of bombax ceiba bark for imparting antioxidant and uv protection activities

The popularity of natural dyes is gradually increasing worldwide because of their sustainable and eco-friendly dyeing properties. the potential of natural dyes to replace synthetic dyes is expected to be explored by a new researchers. bombax ceiba is a tree widely known for medical purposes. the present work focuses on developing functional wool using natural dye obtained from conical prickles of bombax ceiba bark. the colouration of wool using conical prickles of bombax ceiba bark was done in a rota-dyer machine. assessment of the fastness and functional properties of the dyed fabrics was performed. mordants (aluminum ferric sulphate and chitosan) were utilised to dye the wool. satisfactory fastness and good colouration properties were achieved by dyed fabric. more than 76 % antioxidant activity and excellent uv protection were acquired by the dyed fabrics. the dyed wool fabric confirmed k/s>1 and wash fastness ratings in the range “good” to “excellent”. thus, the novel combinations of conical prickles of bombax ceiba bark and various mordants were explored for the functional colouration of wool fabric.
