Microscope Observation Method of Textile Fabric Fiber

Tencel fiber: The longitudinal shape is smooth, the cross-sectional shape is relatively regular round or oval, with a core layer. Modal fiber: There are 1 to 2 grooves in the longitudinal shape, and the cross-sectional shape is irregular and similar to the waist circle, relatively smooth, and has a skin core. Soybean fiber: There are irregular grooves and island-like bumps on the longitudinal surface, and the cross-sectional form is flat dumbbell-shaped and round waist. Bamboo fiber: The longitudinal shape has grooves on the surface, the cross-sectional shape is zigzag, and there is a core layer. Chitin fiber: There are obvious grooves on the longitudinal surface, the edge of the cross section is zigzag, and the core layer has obvious small voids. Viscose fiber: There are grooves on the longitudinal surface, the cross-section is zigzag, and there is a core layer. Cotton fiber: the longitudinal shape has natural twist, the cross-section shape is round waist, and has a middle cavity. Silk: The longitudinal shape has a smooth surface, and the cross-sectional shape is irregularly triangular. Hair fiber: There are scales on the surface of the longitudinal shape, and the cross-sectional shape is round. Polyester fiber: Longitudinal morphology rod shape, cross-sectional morphology surface is smooth, round.
