Identification of various fibers

1, feel the visual method: This method is suitable for scattered fiber state of textile raw materials.
(1), cotton fiber than ramie fiber and other linen process fiber, wool fiber are short and thin, often accompanied by a variety of impurities and defects.
(2), hemp fiber feel more hard.
(3), wool fiber curl and flexible.
(4), silk is filament, long and slender, with a special luster.
(5), chemical fiber only viscose fiber dry, wet state strength difference.
(6), spandex has a very large elasticity, at room temperature its length can be stretched to more than five times.
2, the microscope observation method is based on the fiber longitudinal, cross-sectional morphology to identify the fiber.
(1), cotton fiber: cross-sectional shape: waist round, with mid-waist; longitudinal form: flat band, a natural song.
(2), hemp (ramie, linen, jute) fiber: cross-sectional morphology: waist round or polygonal, in the cavity; longitudinal shape: a cross, vertical lines.
(3), wool fiber: cross-sectional morphology: round or nearly round, some with hair pulp; longitudinal surface: the surface scales.
(4), rabbit hair fiber: cross-sectional morphology: dumbbell type, with hair pulp; longitudinal surface: the surface scales.
(5), silk fiber: cross-sectional morphology: irregular triangle; longitudinal shape: smooth straight, vertical stripes.
(6), ordinary viscose: cross-sectional morphology: serrated, leather core structure; longitudinal form: longitudinal groove.
(7), rich and powerful fibers: cross-sectional morphology: less tooth, or round, oval; longitudinal surface: smooth surface.
(8), acetate fiber: cross-sectional morphology: trilobal or irregular jagged; longitudinal surface: the surface with longitudinal stripes.
(9), acrylic fiber: cross-sectional morphology: round, dumbbell or leaf shape; longitudinal surface: smooth surface or stripes.
(10), polyvinyl chloride fiber: cross-sectional morphology: close to the circle; longitudinal surface: smooth surface.
(11), spandex fiber: cross-sectional morphology: irregular shape, round, potato-shaped; longitudinal surface: the surface dark, was not clear bone-shaped stripes.
(12), polyester, nylon, polypropylene fiber: cross-section morphology: round or shaped; longitudinal surface: smooth.
(13), vinylon fiber: cross-sectional morphology: waist round, leather core structure; longitudinal form: 1 ~ 2 groove.
