The present paper is concerned with the influence of opening roller speed, difference in drum speed and suction air pressure on properties of acrylic open-end and core-sheath friction spun yarns. The results show that opening roller speed and suction air pressure have significant influence on properties of open-end friction spun yarns. In the case of core-sheath yarns, suction air pressure has influence on yarn tenacity and hairiness. However, yarn unevenness and imperfection are not significantly influenced by experimental variables. The results also show that core-sheath friction spun yarns have significantly higher yarn tenacity, modulus and work of rupture and have a lower level of yarn unevenness, imperfections, hairiness, and breaking elongation than open-end friction spun yarns.
