Abstract
Paper of improved properties is produced from pulp in which filler is selectively loaded within the fiber lumens by agitating a suspension of pulp and filler until the fiber lumens become loaded with filler, separating the residual suspended filler from the loaded fibers and vigorously washing the pulp until substantially all of the filler on the external surfaces of the fibers is removed.
