Abstract: Raw sulphonated jute, raw sulphonated jute-cotton and cotton fabrics were bleached under different conditions by varying pH , treatment time, temperature, hydrogen peroxide concentration and fabric-liquor ratio. Bleaching affected the brightness and breaking strength, and the optimum brightness (76.9%) and breaking strength (13.6 kg/f) for the blended fabric were obtained with 6.5% hydrogen peroxide at pH 11, temperature 90oC, treatment time 100 min and fabric-liquor ratio 1: 3. The thermal degradation of bleached sulphonated jute-cotton fabric was characterized by TG analysis and compared with the bleached cotton and bleached sulphonated jute fabrics. It has been observed that the thermal stability as well as brightness and breaking strength of the blended fabric largely depend on the amount of lignin and hemi-cellulose present in the fabric sample.
