 Microscopic View – Fibre Identification

Flax:                                                

Longitudinal View       :  Long,Transparent,cylindrical,sometimes striated appearance.It    has harrow lumen running through centre.

Cross sectional view   :  The cell wall appears thick and polygonal in shape.

Jute:

Longitudinal View       :  Cross wise marks called nodes or joints.

Cross sectional view   :  The fibres have a small central canal similar to the lumen in      cotton.Several sided or polygonal with rounded edges.

Wool:

Longitudinal View       :  Irregular and roughly cylindrical,prominent scale marking or flattened plates..

Cross sectional view   : Oval to circular with variation in diameter medulla is concentric and variable in size.

Viscose:

Longitudinal View       :  Uniform diameter with striation running parallel to the fibre axis.

Cross sectional view   : Differ in cross sectional appearance according to the process used.Basically has a irregular cross section.

Polyester:

Longitudinal View       :  Very regular, rod like appearance.

Cross sectional view   :  Circular in cross section.

Nylon:

Longitudinal View       :  Very regular, rod like appearance.

Cross sectional view   :  Circular in cross section.

 Acrylic :

Longitudinal View       :  Rod like with smooth surface and profile.

Cross sectional view   :  Nearly round or bean shaped.
