So, which claim is true? There are two research findings from Li and Dao, and Xi et al that could provide some hints. With systematic experiments and comparisons with other natural fibers including cotton, jute, flax and ramie, both findings conclude that natural bamboo fibers do not have natural antibacterial properties. However, some extraction method could improve the antibacterial prototype of natural bamboo fiber against bacteria. Gogarneshan and Khan have similar conclusion in their research, in which extractives have influence on antibacterial property of bamboo fiber.
