Abstract:

In order to investigate the property differences of the bamboo fibers extracted from different years and zones, the chemical composition, surface morphology, density, moisture absorption and tensile strength of bamboo fiber were tested. And the bamboo fibers were extracted from sinocalamus affinis with different years and zones by physicochemical method. The results show that with the increase of year, the moisture regains decreases first and then increase with the year increase. The fiber density increase first and then decrease with the increase of the year.The fiber density increases with the increase of height. The moisture regains decrease first and then increase with the increase of height. The density of fiber extracted from three-year and the tip is biggest (1.70g/cm3).And the density of fiber extracted from four-year and the bottom is smallest(1.51g/cm3). The moisture regain of fiber extracted from three-year and the middle is smallest (12.94%). The tensile strength of fiber extracted from three-year bamboo is more stable, and the tensile strength of fiber extracted from four-year and middle bamboo is the highest (787.42MPa).
