Abstract :The aim of this work is to determine the effect of draft ratio and twist level on core visibility ratios of dual core-spun yarns. For this aim, different types dual-core yarns containing PET/Elastane were produced under controlled conditions. To objectively evaluate the visual quality of the dual-core yarns, the frequency of the core filaments appearing on the yarn surfaces was counted on dyed knitted fabrics produced with these yarns by using image processing algorithm . The results showed that the draft ratio and twist coefficient are the important factors influencing the core visibility ratios of dual core-spun yarns.
Keywords : Dual-core yarn, pre-treated dual-core yarn, core visibility ratio, draft ratio, twist coefficient
