ABSTRACT
Fibers are regarded as very elongated particles. Staple bers that are spun into yarns have length/diameter ratios greater than 10,000. The ber lengths of cotton are of the order 25-75 mm; wool bers may exceed 100 mm and are variable in length even when shorn from the same sheep; ¤ax bers may be available in lengths up to 1 m [1]. The corresponding diameters of textile bers range between 3 and 500 μm.
