    Abstract :

    Jute was modified with hydrolyzed sericin fraction of silk in presence of trisodium citrate as the esterification catalyst following a pad-dry-cure technique. Treatment of jute fabric with 8% hydrolyzed sericin in presence of 14% catalyst followed by drying at 95oC for 5 min and curing at 140oC for 5 min, produced optimum results in respect of exhaustion and fixation of reactive dyes having chlorotriazine and vinyl salfone reactive groups, when dyeing was accomplished in absence of salt. Colour fastness to wash, light and rubbing of jute for application of reactive dyes remained unaltered for such prior modification with hydrolyzed sericin. IR spectroscopy indicated incorporation of amino acid residues of sericin fraction of silk in polymeric chains of jute via establishment of ester linkages between carboxylic group of the amino acid moiety and hydroxyl groups of the jute cellulose on pad-dry-cure.
