Research of structural and morphological properties of bamboo pulp and Poplar pulp by sulfate cooking ☆

In this research, we investigated the structural and morphological properties of cellulose from bamboo bambusa blumeana and Poplar wood, obtained by sulfate cooking. Using an automatic fiber analyzer L&W Fiber Tester investigates the length, the width of the fibers, as well as the characteristics of shape factor, number of kinks in the fiber and some other properties. The results show that, compared with the cellulose fibers of hardwood pulp, the cellulose fibers of bamboo are longer (1.8 to 1.0 mm), with a smaller width (17 to 25.8 μm), more curved (shape factor 87.5 versus 92.5) and have a higher number of kinks in the fibers (0.42 vs. 0.29).
