THE INFLUENCE OF SPINNING PARAMETERS ON POLYESTER/VISCOSE DREF-3 YARN UNEVENNESS, IMPERFECTION AND HAIRINESS PROPERTIES

In this study polyester staple fiber core/viscose sheath yams were produced in order to understand the influence of spinning parameters on DREF-3 yam unevenness, imperfection and hairiness properties. Yarns having 65 tex linear density, were produced with using three different core/sheath ratio level x three different spinning drum speed x three different air suction pressure at 4200 rpm constant opening roller speed and 100 m/min constant production speed. The unevenness, imperfection and hairiness properties of experimental yarns were tested with Uster Tester 3, at a speed of 200 m/min for 5 minute. Obtained results were evaluated with regression analysis using SPSS statistical pocket program at 0.05 significance level.
