Abstract
In this study, firstly, it is aimed to spin PTT (Polytrimethylene Terephthalate) based staple Sustans® fibers together with cotton in Open-End rotor yarn production system. In this way, it is aimed to transfer the positive properties of Sustans® fibers such as good elasticity, good dimensional stability, low static electrification and soft hand to the staple yarn structure with a high efficiency spinning technique. In this context, using 5 different ratios of Sustans®/Cotton blends and 100% Cotton, 6 different rotor yarns with Ne 8.25 (71.6 tex) were produced and the quality characteristics of these yarns were tested. In the study, Sustans®/Cotton blends were successfully spun with the Open-End rotor system. As a result, compared to 100% cotton, it was observed that the elongation at break, unevenness, yarn defects and hairiness values were better for yarns containing Sustans® fibers, while the strength values were slightly lower. The optimum blend ratio was concluded to be 50/50% Sustans®/Cotton for the open-end spinning technique.
