Özet

In this study, it was aimed to analyze the effects of raw material and spinning system on physical properties of yarns. For this purpose, natural (100% cotton), regenerated (100% Modal) and synthetic (100% acrylic) yarns were analyzed. Yarns were produced systematically in ring and open-end rotor (OE-rotor) systems. Yarn unevenness, optical unevenness, imperfections, structural properties such as density, CVFS% (roughness), shape (roundness) etc., yarn hairiness, yarn-to-yarn friction, yarn-to-ceramic friction and yarn-to-metal friction properties were evaluated in the scope of the study. When the effect of spinning systems is evaluated, results show that the values of unevenness, imperfections, diameter and roughness for OE-rotor yarns are higher. On the other hand, values of density, shape factor, hairiness and friction for OE-rotor yarns are found lower than ring yarns for all material types. Many researchers state that the effect of raw material on yarn properties is important. However, in this study, it is remarkable that unevenness, imperfections, hairiness and friction values of Modal and acrylic yarns made of fibres with the same length and fineness are fairly close to each other.
