Against the backdrop of a global paper resource shortage,there is a growing need to identify fast-growing tree species capable of pro-ducing long-lasting paper.Three plant species namely Broussonetia kazinoki,Broussonetia papyrifera and hybrid paper mulberry,belong to the Broussonetia genus,were collected from China to study their white bark suitability for pulp and papermaking.Their chemical composition re-vealed that the holocellulose content in Broussonetia kazinoki and Broussonetia papyrifera was more than 80％.The molecular weight distribution of several holocellulose/a-cellulose is observed by GPC,which allows us to better observe the changes of various components on the molecular weight.The yield,lignin,whiteness,and molecular weight of the pulps obtained by NaOH treatment were determined.Optical microscope was used to characterize the fiber length-width ratio and rigidity.Finally,the improvement of the fiber rigidity method based on the Kratky-Porod chain model makes it more theoretical and further reveals the influencing factors of fiber rigidity.This study demonstrates the high potentiality of these three species for papermaking applications.
