Trilobal cross-section
In fibers, trilobal is a cross-section shape with three distinct sides. The shape is advantageous for optical reflective properties and is used in textile fibers. Silk fibers' rounded edges and triangular cross section contribute to their luster; in some cases, synthetic fibers are manufactured to mimic this trilobal shape to … See more The dictionary definition of Trilobal at Wiktionary is a combination of the words "Tri" for three and "lobal" for sides. See more Synthetic fibers are particularly suitable for specific effects such as crimping and texturizing due to their adaptability during production.
