Fiber's Diameter Analyses

The diameter of a fiber is the distance across the fiber’s cross section.The diameter of the natural staple fiber is irregular and varies from one part of fiber to another. Staple fibers diameters are measured in microns. The diameter of the smooth, even manmade filament fibers is uniform. The diameter of man-made fibers can be controlled during the manufacturing process by changing the size of the opening in the spinneret. The size of the spinneret openings, range from fine to heavy. The small opening, produce fine filament fibers. Filament fiber diameters are measured in denier. Natural or manmade fibers can be altered or changed purposely to produce irregularities for special or novelty effects.
