The electrical properties of select fractions of cellulose pulps

The electrical properties of papers made from woodpulp prepared by different processes are known to differ. These differences have been attributed to differences in the quantities of residual pentosans, cooking salts, lignin and hemi-celluloses, as well as to the degree of attrition to which the fibers have been subjected. The study reported here is concerned with the variations in electrical properties observed on sheets of paper made from different lengths of fiber taken from the same pulp. It is concerned furthermore with differences in the electrical properties of sheets of paper made from the same size fibers taken from different pulps.
