Jute fabric has been bleached and dyed at ambient temperature using hydrogen peroxide as bleaching agent and cold brand reactive dye as dyestuff. The fabric is first bleached by using pad-batch method and the spent liquor is reused for bleaching another batch of fabric. Whiteness index of the fabric produced by original liquor is very good while the whiteness index is satisfactory for the bleached fabric produced by spent liquor. Tensile strength retention is also excellent for the ambient temperature bleached samples. The ambient temperature bleached fabric has been dyed with cold brand reactive dye. By following two-step two-bath method of exhaustion and fixation of dye, the spent dye bath is reused. So, the effluent is minimised and optimum utilisation of costly reactive dye is done. The bleach liquor as well as dye liquor is reused, making the bleaching-dyeing process economic and eco-friendly. The technology is ideal for small scale and cottage industry, as the processes are carried out at ambient temperature. Golden fibre, jute, is being utilised for the manufacturing of different value added and diversified product which needs attractive look and feel. Moreover most of these products are produced in small scale sector.
