The bamboo charcoal fiber exhibits longitudinal stripes of continuous black distribution and a cross-sectional honeycomb-like microporous structure with distinct black spots of varying sizes. When boiled in solutions of 70% sulfuric acid, 99% N,N-dimethylformamide, and 20% sodium hydroxide, bamboo charcoal fiber dissolves immediately, producing black granules, which can differentiate it from polyester fibers. Due to the safety requirements of the identification process, dissolution experiments should be conducted using dimethylformamide solution or a 20% sodium hydroxide solution.
