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.
