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 direction (fibre orientation) is in which way most of fibres lengths lie, relative to the axis of the part.
Staple fibre has short fibre, typically measured in inches or fraction of inches, like those naturally found in cotton and wool. Silk, however, is the only natural fibre that does not come in staple lengths but instead in filament lengths.
Morphology is a term used to describe the study of the physical form and structure (see below) of a material and include a broad spectre of characteristics. Fibre morphology contains macro-structure, micro-structure, the sub-microscopic and fine structure of fibres, which are only observable through a light microscope.
Fibres are elongated cells with pitted cell walls. Found in water-conducting tissue, xylem (transport tissue in vascular plants ) and food-conducting tissue, phloem (living tissue carries organic nutrients), along leaf veins and margins, and surrounding vascular bundles in stems.
Elasticity (fibre) is a term used to describe the ability or level of a thread or fabric to return to its original length, shape, or size immediately after the removal of stress and tension.
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.
