Title: Fiber length strength interrelationship for slash pine and its effect on pulp-sheet properties

Author: Wangaard, F. G.; Woodson, G. E.;

Publication Series: Miscellaneous Publication

Description: Based on a model developed for hardwood fiber strength-pulp property relationships, multiple-regression equations involving fiber strength, fiber length, and sheet density were determined to predict the properties of kraft pulps of slash pine (Pinus elliottii). Regressions for breaking length and burst factor accounted for 88 and 90 percent, respectively, of total variation in these properties resulting from a large number of beater runs. At a given level of sheet density, fiber strength and fiber length had a positive influence on both breaking length and burst, and this effect was more pronounced the higher the level of sheet density. An equation that accounted for 80 percent of total variation in tear factor was also developed. At higher levels of sheet density, shorter fibers gave superior tear resistance. The benefits in tear factor generally ascribed to longer (stronger) fibers may be reconciled with these findings when pulp properties are compared at the densities associated with a common level of freeness rather than at specified levels of sheet densitY as was done here.
