The spinline behavior in dual nozzle electrospinning was observed using high shutter speed photography and laser scattering technique. It was found that the spinlines of each nozzle have skewed bell shapes. The solution concentration, the number of nozzles, the nozzle-to-nozzle distance (NND) showed significant effects on both the spinline shape and the fiberweb morphology. They were also resulted from the inter- and the intra-spinline repulsive forces. Especially the fibers collected in the middle of the collecting plate were oriented along the tangential direction to the two webs spun from each nozzle.
