Fiber Blending Irregularities in Cross Sections and on Yarn Surfaces in Relation to Yarn Properties

An analysis of fiber blending irregularities is presented in relation to the disturbances of blend yarn properties resulting from these phenomena. Fiber blending irregularities were assessed using the original method of yarn surface analysis and a new method of yarn cross-sectional division. These methods correctly reflect the disturbances in the mechanical and aesthetic yarn properties resulting from non-uniform mixing of constituent fibers.
