Filament spinning of unbleached birch kraft pulps: Effect of pulping intensity on the processability and the fiber properties [PDF]
Carbohydrate Polymers, 2018 Man-made lignocellulosic fibres were successfully prepared from unbleached birch kraft pulps by using the Ioncell-F technology. Pulps with different lignin content were produced by tailored kraft pulping with varying intensity. The degree of polymerization of the pulps was adjusted by acid-catalyzed hydrolysis and electron beam treatment.

Beatability and runnability studies of ion-exchanged unbleached kraft pulps on a pilot scale
Nordic Pulp and 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 ...

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 ...
