WebThe relationship between the D/Y ratio and the false twist tension, as the D/Y ratio increases, the twisting tension T1 increases, while the untwisting tension T2 decreases. As the temperature increases, the rigidity of the filament decreases, the thermal stress tends to ease, and the false twist tension decreases accordingly. WebThe modern process for false twist texturing is based on a technique patented by Finlayson and Happey in 1933, whereby temporary twist is imparted to a moving yarn upstream of a spindle (twist applicator). The twist is thermally set and cooled before becoming automatically untwisted after the spindle. 21 Sign in to download full-size …
