BLENDING QUALITY mixing homogeneity for natural and synthetic fibers or separation of components for core yarns, wrapped yarns • Arrangement of fibers in the crosssection – radial homogeneity • Variation of mixing degree or composition between cross-section – axial homogeneity • Variation of fiber number between cross-sections – mass unevenness
Testing of fiber bundles presence • Yarn cross-section is divided to matrix of cells - I.B.I. (index of blend irregularity) • Creation of sequences of nearest neighbors of the specified fiber – fiber nearest to yarn center, exhaustive selection of all fibers in yarn crosssection
