In the scope of the study, the effect of fiber blending ratio, yarn count and twist coefficient on fiber migration, packing density and diameter of the cotton/acrylic blended yarns were investigated. The yarn samples with 75-25%, %50-50%, 40-60% cotton-acrylic blending ratios were produced with three different yarn numbers; 20/1 Ne, 24/1 Ne, 30/1 Ne and three twist coefficients; 3.5 α, 4 α, 4.5 α. Thus, totally 27 yarn samples were obtained. The yarn cross-sectional samples were sliced with microtome. The image frames of yarn cross-sections were acquired via digital microscope. The yarn packing density was calculated by using image processing algorithm and the fiber migration was determined via cross-section images. The results were evaluated statistically.
