Electrospinning is a unique method to produce ultrafine fibers (micrometer to nanometer) with high specific surface area from polymer solutions or melts using electrical energy. Typically, electrospinning needs a direct current (DC) in the range of several tens of kV. Currently, electrospinning device has two standards, i.e. vertical and horizontal. This process is carried out at room temperature and at normal pressure. Most of the polymers are dissolved in a suitable solvent before electrospinning process. An electrospinning system consists of three main parts including a high voltage power supply, a spinneret and a ground plate collector. The power supply applies a specific polarity to a polymer solution or melt, the solution is then accelerated towards a collector with opposite polarity. The polymer solution is introduced into a capillary tube and held there by its surface tension force. By applying electric current to the liquid surface via the capillary tube, the electric forces overcome the surface tension forces and lead to the formation of a jet of the solution which exits from the end of the tube. When solution ejects from the Taylor cone tip, due to the instability and high speed that occur in the space between the capillary tip and the collector, the solution jet with a millimeter diameter turns into one or several jets with a diameter in the nanometer range; finally the solvent evaporates and the fibers remain.

Application
 

By using this method different nanofibers can be deposited on the various substrates which can lead to the new industrial scale production. INFL system is widely used for producing nano-filters and nano-respiratory face masks.

specification

Using the industrial production line of these machines, nanofibers for different applications in industrial scale can be produced. These systems are offered with two different mechanisms, i.e. electrospinning with and without nozzle, which by considering their advantages, each one can be used for specific application. This device has three models, i.e. INFL400, INFL800, and INFL1000, which are different with each other based on the volume, production capacity and electrospinning units. Details of technical specifications are presented in the following Table.
 


Advantager of using nanotechnology
 

When the repulsive electrostatic forces overcome the surface tension forces, the destruction, bending, twisting and stretching of fibers occur with respect to the device conditions; occurrence of a combination of these phenomena or each one individually can lead to the conversion of a solution jet with millimeter diameter to one or several jets with a diameter in the nanometer range. So this device can be mainly utilized in production of nanofibers.

Manual and maintenance
 

• Device must be used by a fully trained person.
• When drum is in contact with chemicals, use special gloves to remove it from the device.
• Be careful when mounting the tub at the desired place and avoid applying pressure to the gear and damaging it.
• Make sure tub is fully dry after washing.
• For more details on how to use the device, refer to the device catalog and user guide.

Safety and package
 

• Inappropriate use of the device high voltage power supply can cause electric shock or death.
• Check all connections, especially the system earth connection cable, and make sure they are correct.
• Avoid opening the device door when the high voltage power supply is on; and only connect the high voltage cable to the tub and collector.
• During device operation, make sure that the device door is closed, or use safety glasses to protect your face against the splashing of polymer solution or melt.
