Description 206-213
The viability of reactive dyeing in the same bath without draining the liquor after enzymatic bio-treatment has been
investigated. The comparative impact of applying the one-bath bio-treatment and dyeing method using two sets of
commercially available polyfunctional and bifunctional trichromatic reactive dyes has been studied and the findings are
compared with the two-bath conventional process. Three dyeing recipes in Maroon, Olive and Brown colour combinations
of dyed fabrics are evaluated with respect to the colour strength, colourimetric data and fastness properties. The produced
one-bath bio-treated and dyed samples show fairly high colour strength and satisfactory colour difference values as
compared to the conventional method. The polyfunctional trichromatic reactive dye class is found more sensitive to the type
of pretreatment and dyeing method used, imparting slightly higher colour difference values as compared to those of the bifunctional
reactive dye class. The design and application of the one-bath Bio-method could provide a significant approach
for demanding viscose fabric pretreatment and trichromatic reactive dyeing at reduced time, water and energy parameters.
