Two sets of processed jute fabric viz, alkaline scoured-bleached and bioscoured-bleached jute fabrics were dyed separately with two nucleophilic addition type (vinyl sulphone type) of reactive dyes namely, Remazol Yellow FG and Amidazol Brown GR dyes. From the experiment it is revealed that bioscoured-bleached reactive dyed jute fabric shows higher dye uptake than that produced by alkaline scoured-bleached-reactive dyed jute fabric in case of both the vinyl sulphone type of reactive dyes. Biotreatment results in improvement of handle and wash fastness properties of jute fabric. Brightness of the shade was also improved in case of biotreatment-bleached-reactive dyed jute fabric.
