An Optical Scanning Technique for Measuring Fiber Size

An optical scanning system was used to obtain considerable information related to the fineness and fiber to fiber fineness variability of various samples of natural and man-made staple fibers. The adaptation and use of this system is described as various techniques for presenting an assembly of fibers for automatic optical analysis are considered. Frequency distribution curves of the diameters distribution of several different fibers were defined by using the image analyzer to scan the magnified images of fibers. These data are discussed as the fineness variability of the different staple fibers are analyzed and compared.
