Abstract

A method of introducing and retaining particles of mineral filler inside the lumens of wood pulp fibers is disclosed. The fillers are mixed with a high-consistency pulp slurry so that a portion of the total filler diffuses inside the lumens. The loaded fiber is treated with a chemical flocculating agent that exhibits a higher chemical affinity for the filler than for the fiber. The flocculated filler particles are prevented from diffusing outside the lumens. At equal filler loading levels, paper formed according to the lumen loading process of this invention exhibits superior mechanical strength than paper prepared in a conventional manner.
