Charcoal fiber exhibits longitudinal black stripes with a unique concave-convex honeycomb-like microporous structure in cross-section, characterized by visibly uneven black spots. When boiled in a solution of 70% sulfuric acid, 99% N,N-dimethylformamide, and 20% sodium hydroxide, charcoal fiber dissolves immediately, producing black granules, which can differentiate it from polyester fiber.

Due to the safety requirements of the identification operation, dissolution experiments were conducted using dimethylformamide or a 20% sodium hydroxide solution.
