Crimp refers to waves, bends, twists or curls along the fibre length. It is expressed as crimps per unit length. Some natural fibers are linear, others form two-dimensional or three-dimensional crimps. Crimped fibers tend to have higher elongation than linear fibers.
Fibre direction is in which way most of the fibres lengths lie, relative to the length axis of the part.
After size, fiber length is the most important property of a fiber. Fiber length is critical in processing of fibers and yarns and in the translation of fiber strength to yarn strength. In general, a longer fiber length is preferred. Read more..
Fibre size, often referred to as fineness, is one of the most important properties of fibres. It is usually specified in terms of diameter or linear density. The size of natural fibers is often given as a diameter in micrometre units. It reflects the average width along the fibres length. Read more..
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. However, it can be described as the following; Fibre to fabric engineering can be defined as an interdisciplinary field in which scientific principles, tools of mathematics, engineering techniques, chemistry, physics and other physical sciences are applied in multiplicity of creative textile applications.
