My TAPPI Story: Rory Wolf
TAPPISAFE
The production of high brightness pulps remains one of the principal requirements for many high–value paper products. The need to accomplish this task under the recently proposed cluster rules makes this an especially challenging problem for softwood kraft pulps. Recently, our research group has begun to examine the chemical constituents of kraft pulps that may contribute to a brightness ceiling. As a preliminary study in this field we have examined the potential contribution of ortho– and para–quinone structures to brightness development during multistage bleaching. Employing literature methods, we have found a relationship between the quinone content after the first alkaline extraction stage and the final brightness values of a kraft pulp. The fate of quinones was explored using a D(E*)DED (E* = E, EAr, EO, EP, and EOP) bleaching sequence with a softwood kraft pulp.
