Abstract

PRODUCTION OF HIGH STRENGTH LINERBOARD WITH OXYGEN AND ALKALI Pulp for the production of high strength linerboard is obtained by digesting wood chips in alkaline cooking liquor, defibering, treating with oxygen and alkali, and refining. Linerboard pulp produced by this method has better paper strength properties and is easier to refine than pulp not treated with oxygen and alkali. The treatment is conducted in its best mode at temperatures below 100.degree.C to minimize pulp yield losses.
