Fibre crimp refers to waves, bends, twists or curls along the fibre length. It expressed as crimps per unit length. Some natural fibres are linear; others form two-dimensional or three-dimensional crimps.
Fibre direction (fibre orientation) is in which way most of fibres lengths lie, relative to the axis of the part.

FIBRE MORPHOLOGY OVERVIEW
Fibre size often referred to as fineness, is one of the essential properties of fibres measured in terms of diameter or linear density. The size of natural fibres measured diameter in micrometre units. It reflects the average width along the length of the thread.
Fibre to fabric engineering. It still does not exist an official fibre to fabric engineering title for this vastly wide and large industry segment as it was never undertaken by pro textile associations.
