Microscopic Observation Of Nonwoven Fabrics

Oct 11, 2020

It is to identify non-woven fabric fiber according to its longitudinal and cross-section morphological characteristics.

(1) Cotton fiber: cross section shape: waist round, with middle waist; longitudinal shape: flat belt, with natural curve.

(2) , ramie (ramie, flax, jute) fiber: cross section shape: waist round or polygonal, with middle cavity; longitudinal shape: with cross section and vertical grain.

(3) Wool fiber: cross section shape: round or nearly round, some have hair pulp; longitudinal shape: there are scales on the surface.

(4) Rabbit hair fiber: cross section shape: dumbbell type, with hair pulp; longitudinal shape: surface with scales.

(5) Mulberry silk fiber: cross section shape: irregular triangle; longitudinal shape: smooth and straight, longitudinal stripe.

(6) Common viscose fiber: cross section shape: zigzag, skin core structure; longitudinal shape: longitudinal groove.

(7) Rich fiber: cross section shape: less teeth, or round, oval; longitudinal shape: smooth surface.

(8) Acetate fiber: cross section shape: trilobate or irregular zigzag; longitudinal shape: longitudinal stripe on the surface.

(9) Acrylic fiber: cross section shape: round, dumbbell shaped or leafy; longitudinal shape: smooth or striped surface.

(10) The cross-section shape of the fiber is close to circular; the longitudinal shape is smooth.

(11) Spandex fiber: cross section shape: irregular shape, round and potato shape; longitudinal shape: dark and deep surface, unclear bone shaped stripes.

(12) , polyester, nylon, polypropylene fiber: cross section shape: round or irregular shape; longitudinal shape: smooth.

(13) Vinylon fiber: cross section shape: waist round, skin core structure; longitudinal shape: 1 ~ 2 grooves.
