| Abstract: |
| Fiber morphology and chemical composition of different parts of green bamboo （Bambusa oldhami） including tip, middle, root of bamboo, and outer layer (OL), middle layer (ML), inner layer (IL), and nodes from different positions of bamboo were analyzed and compared by using fiber measurement instrument, FT-IR, ICP emission spectrometer, XRD and SEM. The results showed that, OL, ML, IL, and nodes from different positions of bamboo mainly comprised of cellulose, lignin and hemicellulose; the cellulose content of ML from bamboo root was the highest while cellulose content of IL from bamboo tip was the lowest; the amount of non-cellulose components from OL and IL including lignin, pentosan, ash, extraction and metal ion content were higher than ML; crystallinities of ML and nodes were higher than OL and IL in the middle position; surface densities of OL and IL were higher than ML. These results indicated that ML has the greatest advantage as the raw material to prepare dissolving pulp. Dissolving pulp uniformity and reactivity will be affected by the differences of different parts of bamboo when it was used as raw material. |
