Mechanical Properties of Air-Jet Yarns Spun on Different Systems

Popis výsledku v původním jazyce

In yarn production, the technology of twist insertion is the major factor that affects the structure and ultimately the properties and performance of the produced yarn. Moreover, the differences within the same spinning technique have, to some extent, asimilar effect. In this work, we are studying the effect of the design of the nozzles of Murata Vortex Spinning (MVS) and Reiter air-jet spinning (J20) on the resulted yarn structure and properties. The scanning electron microscopy (SEM) images of the yarns are used to show the variations in yarn structures, while the mechanical properties of air-jet yarns (MVS and J20) are studied and compared to rotor spun yarns of similar counts. Sonic modulus as measured by the Dynamic Modulus Tester (DMT) producedby Lawson-Hemphill is compared to the results of the standard mechanical and the cyclic loading tests. The impact of the dynamic modulus is also evaluated.
