Raw jute fabric was subjected to two bleaching agents namely hydrogen peroxide and peracetic acid. Bleached jute fabrics were pre mordanted with alum, copper sulphate and ferrous sulphate and then dyed with four natural dyes: madder, turmeric, eucalyptus leaves and Indian almond leaves. The effect of bleaching agents on various physical properties like weight loss, tensile strength, whiteness, yellowness and brightness indices were studied. The effect of bleaching on colour development using different natural dyes was examined. Peracetic acid bleached samples were found to have high degree of whiteness with very less damage compared to hydrogen peroxide bleached samples. Peracetic acid bleached samples were found to be relatively darker.
