Abstract
Bu araştırmada fabrikalardan temin edilen PES filament iplikleri , piyasalarda ençok kullanılan turlarda büküm (197-301-406-505-631) verilmiştir. Bu işlem hem tek kath hem de çift katil iplikler için yapılmıştır. Kullanılan büküm makinası Ratti-TRN312 modelinde ticari bir büküm makinasıdır.
Yapılan deneyler (büküm ve numara ölçme) sonucunda bazı değerler hesaplamalar yardımıyla da bulunup , bu değerler tablo ve grafiklerle istatiksel bir biçimde değerlendirilmiştir. Sonuç olarak iplikteki kısalmanın büyük ölçüde numara ve tura bağlı olduğu bulunmuş , büküm gerilimine ise bağlılığının çok az olduğu görülmüştür. Bununla birlikte iplikte meydana gelen kısalmanın büküm açısını , büküm katsayısını, özgül hacmi, paketlenmeyi değiştirdiği izlenmiştir.
In this research, PES filament yanış equipped with twists( 197 -301 -406-505 - 631 ) which are mostly used in markets are presented. This application was done both for singleyams andtvvo ply-tvvisted yams. Ratti-TRN312 used as a twisting machine is the commercial twisting machine as a modeL To fix retraction caused by tvvisting in PES filament yams, after tvvist and number were measured according to the tests, some values were found with the help of calculations. These values were statistically given by charts and graphs. As a result, that retraction in yams is generally dependent on the number and tour was f'ound and that the effect of winding tension in base situation is very little was observed. Morever , that retraction in yams change tvvisted anğle , twisting coefficient, spacial volüme, packing was realized.
