Effect of electrospinning process on structure and property of electrospun PA6/MWNTs yarn

In this paper,multiwalled carbon nanotubes(MWNTs) were used to reinforce electrospun PA6 yarn.The effects of spinning voltage,vertical distance,electric field intensity and other electrospinning parameters were investigated.The results indicated that the increase of spinning voltage not only increased the diameters of yarns and fibers,crystal linity degree,and fracture strength but also decreased the adherence between fibers.As the vertical distance was enlarged,the fiber orientation in yarn,crystal linity degree,fracture strength and initial modulus of yarns were improved.Under a certain fixed electric field intensity,the fiber orientation in yarn,fracture strength,elongation at break,initial modulus are improved by enlarging voltage and vertical distance.
