Abstract : Study was conducted to investigate the dyeing potential of Quercus robur L. (fruit cups) dye
and Salix alba L. (wood extract) mordant on wool and pashmina fabrics. The experiment was conducted keeping in view the
environmental safety by using unutilized plant materials and excluding the usage of chemical agents. The dyeing was carried
out individually including and excluding mordant adopting different mordanting methods. The parameters like percent absorption,
colour coordinates, colour strength (K/S), relative colour strength and colour fastness with regard to washing, light and
rubbing were investigated. The results revealed higher percent absorption of mordanted samples than unmordanted samples.
Colour coordinates (L*a*b*, Chroma, hue and ∆E) of dyed wool and pashmina fabric exhibited satisfactory results.
The colour strength (K/S) and relative colour strength of pashmina fabric recorded higher than wool fabric. The
fastness properties to washing, light and rubbing showed satisfactory grades including and excluding natural mordant.
However, the grades of mordanted samples were found better than unmordanted samples. The dye and mordant in isolation
and in combination showed beautiful colours and shades on selected fabrics with satisfactory retention properties, hence
can be utilized commercially for coloration of wool and pashmina fabrics.
