Abstract:

In order to reduce the fiber diameter and improve melt centrifugal spinning efficiency, this paper presented a centrifugal spinning by linear and radial friction-free stretching of jet. A simple mathematical model of this method was established. The key parameters of the test equipment was determined based on this model. For the melt centrifugal spinning of polypropylene material for test the equipment, the largest diameter of the collected fiber at 1 - 2 mm distant from the edge of the rotating disk was 6.5 - 10.5 μm. By the melt flux and the orifice diameter forming the initial jet, the calculated deviation of the instantaneous radial moving maximum speed of jet and rotating disk linear speed is not greater than 18%. It is considered that the theoretical model is effective. When the test equipment is upgraded to continuous production mode, the melt centrifugal spinning efficiency is 0.820 g/min under the cinditions of the average diameter of fiber is 0.8 μm and the rotation speed is 8 000 r/min.

Key words: centrifugal spinning, radial stretching, friction free stretching, jet speed, rotating disk linear speed
