This drawback is all the more apparent,the greaterthe differences in the physical-chemical structure of the fibers.  \nIn spite of the long tradition of using fiber mixtures inproduction,the problem of evaluating the nonhomogeneity of thecomposition has not been solved.  \nThere have indeed been studies in which the concept ofevaluating the degree of nonhomogeneity has been formulated,butthe methods of utilizing these indices have not been indicated inthem.  Therefore,the current status is briefly presented in thefollowing considerations and the trend of the work to create thebasis for qualifying yarns from the standpoint of compositionalnonhomogeneity is indicated.  \n# Indices for evaluating the nonhomogeneity of a yarn from amixture of fibers\n\nThe evaluation of the nonhomogeneity of a yarn from amixture of fibers should demonstrate:  \n(a)  the extent to which fibers are not uniformly arrangedin the cross section of the yarn,  \n(b)  the variability of the percentual proportions of fibersin the successive sections of the yarn or semiproduct.  \n# Evaluating the distribution of fibers in the cross-sections ofthe yarn\n\nEvaluation of the fiber distribution in the cross-sectionsof the yarn should explain:  \n(a)  whether the fibers have a tendency to migration  \nassociated with their properties(i.e.,a favored accumulation inthe middle or outer layers of the yarn),  \n(b)  whether the fibers form groups(clusters)or arerandomly distributed in the cross-section of the yarn.  \nIn order to determine the migration tendency of the fibers,a simple and straightforward study/interpretative method is theactualization of yarn sections,outlining with a microscope forprojecting the fibers,depicting the boundaries(primarily in theform of concentric circles),and reckoning each of the  \nconstituents in each zone of the fibers.  The sums of fibers ofeach of the constituents in the successive zones in all thesections,the total sum of each of the constituents and finallythe proportions:  total and in the successive zones for each ofthe constituents,are then established.  The results are plottedon a circle diagram.  \nThe weak side of this method is that the lack of data formaking a judgment,or the variability in constituent  \ndistribution,as disclosed is substantial.  For this reason,Coplan and Block [2]proposed the use of IBI,an index synonymouswith the statistical square root of \"chi-squared.\"  \nHamilton [2]suggested using the coefficient of migrationfor evaluating the tendency of the fibers to assume a position inthe core or on the surface of the yarn;however,in view of thelack of further connections of this index with the otherparameters of the yarn it did not enjoy widespread use.  \nMorton and Yen [1]proposed evaluating the migration of thefibers by calculating the mean moment of the first degree of theposition of the fiber relative to the center of the yarn cross-section:  \nwhere:  \nr1 --the distance of the fiber center from the yarn centerfor the successive segments of the fiber with a length d1,  \n1--the length of the fiber.  \nWith a uniform migration of the f","cbCainvn70DBqCG2","https://ap.wps.com/l/cbCainvn70DBqCG2","pdf",1185146,32,"English","# Evaluation of fiber blending in yarns prepared from mixtures\n## Indices for evaluating the nonhomogeneity of a yarn from a mixture of fibers\n## Evaluating the distribution of fibers in the cross-sections of the yarn","[{\"question\":\"What main defect do fiber-mixture yarns exhibit?\",\"answer\":\"They exhibit a nonhomogeneous surface appearance, whose severity increases with greater differences in the fibers’ physical-chemical structure.\"},{\"question\":\"What should the evaluation of yarn nonhomogeneity from a fiber mixture demonstrate?\",\"answer\":\"It should quantify (a) how uniformly fibers are arranged in the yarn cross-section and (b) how variable the fiber percentage proportions are across successive yarn or semi-product sections.\"},{\"question\":\"How is fiber distribution in the yarn cross-section evaluated to study migration and grouping?\",\"answer\":\"Migration tendency can be studied by projecting yarn sections under a microscope, outlining fiber boundaries, counting constituents in concentric zones, and plotting results (e.g., circle diagrams).
