Water absorbency,retention and wicking properties of electrospun fibrous bundles

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