Microscopic observation: Fibers are identified based on the longitudinal and cross-sectional features of the fibers.

(1), cotton fiber: cross-sectional shape: waist round, with a middle waist; vertical shape: flat ribbon, with natural rotation.

(2), hemp (ramie, flax, jute) fiber: cross-sectional shape: waist round or polygonal, with a middle cavity; vertical surface shape: there are horizontal sections, vertical lines.

(3), wool fiber: cross-sectional shape: round or nearly round, some have a pulp; vertical form: the surface has scales.

(4), rabbit hair fiber: cross-sectional shape: dumbbell type, with pulp; vertical form: surface has scales.

(5), mulberry silk fiber: cross-sectional shape: irregular triangle; vertical surface shape: smooth and straight, longitudinal stripes.

(6), ordinary viscose: cross-sectional shape: zigzag, sheath core structure; vertical shape: longitudinal grooves.

(7), rich and strong fiber: cross-sectional shape: less tooth shape, or round, oval; vertical form: smooth surface.
