Abstract:Melt blown electrospinning is a method of combining melt blown with melt electrospinning. In this study, we developed the multi nozzle melt blown electrospinning machine. The significant point of this method is to use air blowing force as well as electrostatic force at the same time. Also, this machine has many kind of processing parameters. such as applied voltage, spinning distance, tempareture at polymer reservoir, tempareture at nozzle, air flow rate, flow rate of melt polymer, molecular weight, and addictives. We successfully prepared nonwoven polypropylene fiber mat by controling these parameters. In this work, we studied relationship between air flow rate at nozzle and fiber diameter. In our previous study, we have successfully prepared an electrospun syndiotactic polypropylene (sPP) fibrous membrane from solution at slightly elevated temperature. But, the solvents used for electrospinning of sPP solution system, which is difficult for mass production, and furthermore these solvents are harmful and not environment-friendly. In this study, we developed multi nozzle melt blown electrospinning machine. The point of consequence in this machine is to use coincidentally two kinds of force, for instance, air blowing force and electrostatic force. We strongly anticipate that air blowing force increases production rate and electrostatic force produces thin diameter of fibers, respectively.
