A comparative study of bamboo Lyocell fiber and other regenerated cellulose fibers 2nd ICC 2007, Tokyo, Japan, October 25–29, 2007

Abstract A new type of regenerated cellulose fiber can be made from bamboo cellulose by the Lyocell process. In this paper, the morphology and crystal structure of the bamboo Lyocell fiber was investigated by optical microscopy, scanning electron microscopy, and wide angle X-ray diffractometry. Moreover, the mechanical properties, fibrillation behavior, moisture adsorption property, negative ion effect, and antibacterial capability of the bamboo Lyocell fiber were studied. The results showed that the bamboo Lyocell fiber proved to be similar to the structure and properties of wood Lyocell fiber, such as smooth surface, circular cross-section, high crystallinity, high tensile strength, low elongation at break, good moisture adsorption property, and easy fibrillation. Furthermore, the bamboo Lyocell fiber surpassed wood Lyocell fiber concerning negative ion effect and antibacterial property.
