Abstract:

A self-made vertical electrospinning device with a ring electrode as the collector was used to produce electrospun nanofibers. Infouences of deposition time, diameter of fiber and orientation of fibrous bundles for water absorbency and retention and wicking properties wewe studied. Results show that water absorbency and water retention rate are both increased with the increase of deposition time, while they show a slight decreading trend with the increase of the diameter of fiber. In addition, the wicking height of fibrous bundles increased with the increase of the deposition time the degree of orientation. However, the wicking height decreased with the increase of the fiber diameter.

Key words: electrospinning, polyacrylonitrile, ring electrode, nanofibrous bundle, water absorbency and retention, wicking property
