Bleaching Investigations on Bamboo (Dendrocalamus strictus) Pulps

摘要

Bleaching studies were carried out on bamboo (Dendrocalamus Strictus) pulp using different bleaching chemicals, viz., calcium hypochlorite, chlorine dioxide, and hydrogen peroxide in different sequences with a view to retain the tear strength of the unbleached pulp to the maximum extent. Studies have shown that the H/C (40:60) EHH sequence improves the viscosity, fibre strength index, and the tear strength of the bleached pulp over the conventional CEHH bleached pulp. The D/C (20:80) EDH sequence retains the maximum tear strength of unbleached pulp.
