Spinning is a refinement of jet spinning system which has distinctive features such as the capability of spinning % 100 carded cotton yarn and producing ring-like yarn structure even at high speeds with low cost. Comparison of vortex yarn structure with yarns produced by other spinning methods and also the main production factors (delivery speed, drawing rate, spindle type etc.) influencing the yarn structure have been the main subjects in the literature lately. However as in all spinning systems, the possibility of obtaining finer vortex yarns and the tensile behavior according to yarn count is still a main concern for the yarn producers. In this study, after the vortex yarns at different yarn counts (Ne 20, Ne 30, Ne 40) were produced on MVS 810 machine from the same raw material, the tensile properties (tenacity, breaking elongation, work to break, breaking force) of each yarn were measured with Uster Tensojet test equipment. According to test results of the statistical analyses by using the experimental values obtained from the tests, we determined that tensile properties of vortex yarns were directly influenced by the yarn count. |
