Investigation of dyeing methods on wool fabrics with hibiscus and its antibacterial efficiency

The present paper deals with the application of natural dyes extracted from powdered Hibiscus flowers and leaves on 100 % woolen fabric. For this puposes, two mordants (copper sulphate, CuSO4.5H(2)O and tin (II) chloride, SnCl2) and the application methods (pre-, meta-, post-mordanting) were used and their effects on dyeability, color characteristics, fastness properties and antibacterial activities of dyed-mordanting woolen fabric were investigated and evaluated. The color fastness with respect to washing and rubbing was quite satisfactory for both mordant reagents. Unless cupper sulphate was not shown antibacterial efficiency, high antibacterial activity was obtained using tin chloride as a ordant reagent.
