Felt (fabric) is the name of a unique textile fabric made of a random fibrous material classified according to a type of manufacture.
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.
After size, fibre length is the essential property of fibre. Fibre length is critical in the processing of fibres and yarns and the translation of threads strength to yarn strength.
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.
