Separation of Bamboo Fiber with Pressurized Hot Water Treatment

: For the Effective Use of Vegetation Base Material

Abstract

We investigated appropriate processing conditions required for stably and efficiently separating the fibers from bamboos by using a pressurized hot water treatment, and we could confirm 210 °C as the appropriate treatment temperature. We also found that the fibers can be separated and collected efficiently by extracting an appropriate amount of lignin from the bamboos. Although the bamboo fibers treated at 210 °C have lower tensile strength than those treated at 200 °C and 190 °C, they can be separated efficiently. Thus, the optimum temperature for the separation of bamboo fibers is 210 °C.
