Electrospining technique is one of the hotest topics all over the world. The main form of the electrospun products is generally nonwoven fiber web with the poor mechanical properties. Consecutive PA6/MWNTs nanofiber filaments were successfully fabricated by an improved electrospining method. Peregal O was used as the bath to post-draw the as-spun filaments and the effects of draw ratio on their structures and properties were studied. The results show that with the increase of the draw ratio, the diameters of filament and fiber decrease; while the degree of orientation arrangement and crystallinity of the fibers is obviously improved and the breaking strength and initial modulus of the filaments increase. As the maximum draw ratio reaches 1.7, the breaking strength and initial modulus of the filament are 2.64 times and 4.2 times as compared to those of the control sample respectively.
