Description: This paper has been prepared in order to discuss Fiber Loading™ for lightweight, high-opacity bible paper. Incorporating fillers within pulp fibers has been subject to research since 1960 (Green et al. 1962, Scallan et al. 1985, Allen et al. 1992). Fiber Loading™ is a method for manufacturing precipitated calcium carbonate (PCC) directly within the pulp processing system. The Fiber Loading™ process results in fiber loaded precipitated calcium carbonate (FLPCC™) being partly deposited both within the fiber on the fiber walls and in between the fibers, targeting replacement of cellulose fibers, due to the fact that fillers are normally cheaper than the cellulose fibers. The Fiber Loading™ process results in potential raw material and energy savings for the papermaker. In addition, there are potential increases in both the physical and optical paper properties, as well as increasing the environmental savings by reducing free solids in the paparmaking process water stream. A major drawback of using commercial, PCC filler in making paper is that a high proportion of filler-to-fiber in the sheet impairs the strength of paper. Therefore, papermakers utilize relatively low maximum filler-to-fiber ratio to maintain sheet properties. Fiber Loading™ bonds some of the FLPCC™ directly to the fiber and other is contained within the fiber. This allows the maximum filler-to-fiber ratio to be increased without sacrificing sheet properties. Fiber Loading™ is particularly suited for Bible paper applications where high physical and optical paper properties are needed by applying high filler levels at the same time.
