Abstract

Production of a lightweight, high opacity printing paper is a common goal of papermakers using virgin or recycled fibers. Fiber loading is an innovative, commercially viable process that can substantially upgrade and extend most types of wood fibers. Fiber loading, a process carried out at high consistency and high alkalinity, precipitates calcium carbonate (PCC) in situ within pulp fibers. Because paper made from fiber-loaded pulp is stronger than that made by the conventional addition of PCC, it is an ideal technology for producing a reduced basis-weight paper from virgin and recycled high-yield pulps. This paper summarizes the fiber-loading technology and illistrates how it can be applied on a typical recycled newsprint and thermomechanical pulp (IMP) furnish to produce light-weight paper without compromising strength or optical properties. Economic, environmental, and energy advantages of the fiber-loading technology for producing lightweight, high opacity paper are projected for a hypothetical huge capacity U.S. newsprint mill.
