This study uses a nanofibrous membrane produced using electrospinning to undergo processing, to form a yarn with twist of 2.4, 4.0, 5.6, and 7.2 thermal pulsed currents (twist/cm). The optimum twist multiplier values are chosen and used to discuss the tendency of stress and strain. Furthermore, the draw ratios of 1.1, 1.2, 1.3, and 1.4 are applied, to determine which provides an optimum strength. The result showed that yarn with fineness of 40tex corresponding with twist multiplier of 36 and draw ratio of 1.4 have strength of 219.3g (stress of 5.14 cN/tex). This result can be applied for the further study of continuous nanofibrous yarn.
