Assessment of the dyeing properties of pigments from five fungi and anti-bacterial activity of dyed cotton fabric and leather

摘要

The present study was aimed to assess the anti-bacterial activity and dyeing property of the pigments obtained from five fungal species. Cotton fabric and leather samples were dyed with the purified pigments and their anti-bacterial activity was assayed under in-vitro conditions. Post-mordant cotton fabric and leather samples exhibited maximum bacterial reduction when compared with the pre-mordant and dyed samples. Pigment exhaustion, colour coordinates and fastness properties of the dyed cotton fabric and leather samples were also assessed. The toxicity of the pigments was evaluated by seed germination assay.
