Newsprint Grade Groundwood Pulps from <I>Melia Azedarach</I> Linn. (Persian lilac</I>)

Abstract

Laboratory experiments on the production of groundwood pulp from Melia azedarach, Linn. Are described. Standard pulp sheets were prepared from 100 per cent groundwood pulp from the species and from a mixture of 60 per cent groundwood pulp and 40 per cent imported bleached sulphate pulp. The rate of grinding is slow, energy consumption is high and the brightness of the mechanical pulp is poor. The strength properties are quite satisfactory. The wood is not suitable for the preparation of groundwood pulp for manufacture of newsprint.
