Effect of Yarn Physical Properties on Fiber Migration and Packing Density of Cotton/Acrylic Blended Yarns

Abstract

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.

Investigation into the effect of the blend ratio on the structure and properties of dual-feed-opening rotor-spun yarn

“…32 and Hui 33 all evaluated the blending effect of blended yarns by the Hamilton transfer index. Celik and Canli 34 sliced cotton/acrylic blended yarns in three blend ratios. The yarn packing density was calculated by using an image processing algorithm and the fiber migration was determined via cross-section images.…”
