Preventing Strength Loss of Unbleached Kraft Pulp [PDF]
, 2003 Kraft pulp fibers lose inter-fiber bonding ability when they are dried during the manufacture of paper. Adverse environmental consequences of this loss include (a) limitations on the number of times that kraft fibers can be recycled, (b) reduced paper strength, sometimes making it necessary to use heavier paper or paperboard to meet product strength ...

Enhancing antimicrobial activity in unbleached kraft pulp using laccase and phenolic compounds [PDF]
BioResources, 2013 Unbleached kraft pulp fibers were reacted with laccase in the presence of different phenolic compounds (isoeugenol, butyl p-hydroxybenzoate, p-coumaric acid, and ferulic acid) in order to confer them with new properties.

Beatability and runnability studies of ion-exchanged unbleached kraft pulps on a pilot scale
Nordic Pulp & Paper Research Journal, 2009 It has earlier been shown that the counter-ion to the charged groups in the fibre has a significant effect on the beatability of fibres, but large-scale investigations of this effect are scarce in ...
