High yield and enhanced performance fiber
A method of wood pulping having a significantly increased yield is disclosed.Wood chips are chemically pulped to a high kappa number, providing a first accepts component and a first rejects component.The first rejects component is subjected to a high consistency pulping process such as a substantially mechanical pulping process to generate a second accepts component and a second rejects component.The first accepts component may be used in the production of saturating kraft paper with excellent saturability and resin pick up.The second accepts may be used as a second fiber source in the production of multiply linerboard and unbleached paperboard with enhanced stiffness, strength, and smoothness.Alternatively, the first accepts component may be blended with the second accepts component to produce fiber blends, which may be used in a production of paper-based products having enhanced strength and stiffness at low basis weight.		©Questel
