EXPLORING THE RELATIONSHIP BETWEEN YARN TYPE AND PACKING DENSITY: A STUDY OF SINGLE-PLY, TWO-PLY, AND SIRO-SPUN YARNS

Studying the fiber positioning in yarn structure is essential point to understand different characteristics of yarns that counted as alternatives each other. This study explores packing densities single-ply, two-ply and Siro-spun spun have been stated alternative types considering production method or structure. In study, Modal, Tencel, polyethylene teraphtalete, cotton fibers represent micro, regenerated, synthetic, natural were used for 29.50 Tex yarns. Cross-sectional views acquired according hard sectioning method, calculated with image processing tools. Yarn ratio total area within cross-section cross-section. Results showed single ply ring-spun siro-spun are a more circular shape greater values than Besides, produced from least density spinning technology. Similar obtained micro PET single-ply Packing also compared USTER diameter significant relations between those found.
