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..
Fibres are elongated cells with pitted cell walls. They are 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.
