Abstract:

In order to obtain refined nanofibers, polypropylene(PP) melt was electrospun into fibers by adding stearic acid on a selfmade melt differential electrospinning unit, The effects of stearic acid content on PP fiber diameter were discussed,At the same time the airflow speed of the pneumatic convulsions device for fiber drawing were explored. The result showed that PP fibers obviously thining as the addition of stearic acid was 2%-10% by mass fraction and the spinning temperature was 260℃; When the stearic acid mass fraction is 4%, fiber diameters are relatively the finest. Fiber diameter significantly thining when going into the air velocity increased from 13 m/s to 29 m/s(Maximum speed is 29m/s). the produced PP fiber had the diameter generally below 500 nm and the average diameter of 420 nm as the mass fraction of stearic acid was 4% and the air velocity was 29m/s.

Key words: polypropylene, stearic acid, refining diameter, air velocity, nanofiber
