What is "Orientation" - Definition & Explanation

a) The degree of parallelism of fibres, usually as a result of a combing or attenuating action on fibre assemblies that causes the fibres to be substantially parallel to the main axis of the web or strand.

b) A preferred direction of linear molecules in the fine structure of fibres and usually caused by so stretching an extruded fibre that the length direction of the molecules tends to lie parallel to the main axis of the fibre.

c) In the case of natural fibres, a preferred direction of linear molecules laid down during growth, e.g. a spiral around the fibre axis in cotton.

The alignment of the crystalline structure in polymeric materials so as to produce a highly uniform structure. Orientation can be accomplished by cold drawing or stretching during fabrication.
