Bacon, Carbon fibers from Rayon precursors, in Chemistry and Physics of Carbon, vol. 9, ed. by P.L. Walker Jr, P.A. Thrower (Marcel Dekker, New York, 1973), pp. 1–102. The cross section depicts the shape of the various textile fibers. Each textile fiber offers a distinct cross sectional appearance when seen under a microscope. The shapes vary from round to oval and flat, different shapes determines certain characteristics of the textiles. Though the majority of synthetic fibers have a circular cross section, but the shape could be altered or engineered during the manufacturing process. The cross-sectional shape is responsible for certain physical propert…
