Modification to Kraft Pulping and Bleaching for Higher ...

Goals / Objectives Kraft pulping of hardwoods is a high temperature treatment that modifies and extracts most of the lignin from the wood chips. The resulting pulp contains 2-4% lignin at a yield of 45-55% on chips. White paper is made after the pulp is bleached. The bleaching process is comprised of delignification stages which lower the lignin content to ~0.5% followed by brightening stages ...

Mar 14, 2019· Refining (i.e., mechanical beating of pulp) is a common procedure that is used in paper-making to improve the mechanical properties of the final product. The improvements caused by refining are mainly attributed to increased density and to a better bonding between fibers. In this work, we study how various mechanisms that can be triggered by refining affect the tensile behavior of the sheets.
