In the study the authors examine the fiber preparation processes with the objective of demonstrating that dry-disintegration is feasible and capable of yielding a useful fiber. The project is linked with research directed toward dry and semi-dry forming methods. The fiber product is rated on the basis of yield, fiber length, and the formation, strength, brightness and opacity of a paper specimen formed by standard wet-process methods. At 18% moisture content, crumbs of dewatered pulp have been processed in disk refiner to yield fibers suitable for air forming. In the 'best effort to date' fiber length (weighted) was 1.20 mm, not significantly different from the wet-slushed control at 1.26 mm. Other methods and moisture values yielded lengths as short as 0.88 mm. Tensile index and tear for handsheets from the furnished were 16.2 Nm/g and 139 mN; well below 27.0 Nm/g and 273 mN for the control. Press drying doubles the performance of the wetlaid sheets, however, causing even the dry fiberized furnish to approach virgin newsprint strengths. Performance of early air-formed sheets was 50-60% that of water-laid, press-dried sheets. Results to date show that dewatered crumbs of ONP can be fiberized with good yield at moisture contents in the range from 6% to nearly 60%. Damage to the fiber is greatest at lower moisture content and decreases as moisture level is elevated.
