Measurement of Fiber Mixing in Yarns

Abstract

A method based on a modification of the "nearest neighbor" relationship, as used in ecology, is developed for evaluating the extent of mixing of nonhomogeneous fibers in a blended yarn. The evaluation parameter is the degree of randomness in the radial fiber dispersion of a yarn. Simulated cross sections are created for study in such a manner that they feature either randomness or some imposed form of nonrandomness. The procedure for applying the method and the manner of evaluating its results are explained in detail. The method of computation has been programmed so that it can be per formed on a computer.
