Bleaching of jute has become essential for making white glossy fabric or
base material for coloration intended for value added and diversified
products. The conventional hot hydrogen peroxide bleaching process
produces white fiber with high loss of tensile strength and impairing the
feel. On the other hand newly developed peracetic acid bleaching of jute
produces minimum loss of tenacity without impairing the feel but whiteness
achieved is slightly low. Partial bleaching of jute was carried out
using 25%, 50%, and 75% of the normal dose of bleaching agents and
their whiteness index as well as tensile strength were evaluated. In all the
cases hydrogen peroxide produced 5–8 grade higher whiteness in
HUNTER scale while peracetic acid bleached sample retains higher tensile
strength. So, two-step bleaching was carried out using hydrogen peroxide
and peracetic acid following single-bath and double-bath processes. Twostep
single-bath bleaching of jute fabric using 75% peracetic acid followed
by 25% hydrogen peroxide bleaching treatment results in best effect with
respect to optical and physical properties.
