Microscope picture
Microscopic observation method: the fiber is identified according to the longitudinal and cross-sectional morphological characteristics of the fiber.
(1), cotton fiber: cross-sectional shape: round waist, with a middle waist; longitudinal shape: flat ribbon, with natural twist.
(2), hemp (ramie, flax, jute) fiber: cross-sectional morphology: waist round or polygonal, with a cavity; longitudinal morphology: with horizontal joints, vertical stripes.
(3) Wool fiber: cross-sectional morphology: round or nearly round, some with pith; longitudinal morphology: scales on the surface.
(4), rabbit hair fiber: cross-sectional shape: dumbbell-shaped, with hair pulp; longitudinal shape: scales on the surface.
(5) Mulberry silk fiber: cross-sectional shape: irregular triangle; vertical shape: smooth and straight, with stripes in the longitudinal direction.
(6), ordinary viscose fiber: cross-sectional shape: zigzag, skin-core structure; longitudinal shape: longitudinal grooves.
(7) Rich-strength fiber: cross-sectional morphology: less tooth shape, or round, oval; longitudinal morphology: smooth surface.
(8). Acetate fiber: cross-sectional shape: trilobal or irregular zigzag; vertical shape: longitudinal stripes on the surface.
(9) Acrylic fiber: cross-sectional shape: round, dumbbell-shaped or leaf-shaped; longitudinal shape: smooth or striped surface.
(10). Chlorine fiber: cross-sectional shape: close to circular; vertical shape: smooth surface.
(11) Spandex fiber: cross-sectional shape: irregular shape, round, potato-shaped; longitudinal shape: dark and deep surface, with unclear bone-shaped stripes.
(12), polyester, nylon, polypropylene fiber: cross-sectional shape: round or irregular; longitudinal shape: smooth.
(13) Vinylon fiber: cross-sectional shape: waist-round, leather-core structure; longitudinal shape: 1 ~ 2 grooves.
