Definitions
- Such devices are basically known from the prior art.
- a polymer in the form of a polymer melt or in the form of a solution is introduced into an electric field and spun into fibers by the action of the electric field.
- An electrode usually forms a receiving device for the spun fibers, while the counter electrode is designed as a spraying electrode or spray nozzle.
- Spray electrodes or several spray plates arranged side by side, in particular triangular, trapezoidal, square or rounded Are shape. It is preferred here if the spray electrodes or spray plates are arranged next to one another at a distance in the range from 2 to 10 cm. On the one hand, the peak effect is most pronounced and, on the other hand, the nano and / or microfibers produced by the electrostatic spinning process can be deposited into a particularly regular nonwoven with spray electrodes or spray plates. The same applies, of course, in the aforementioned embodiment with a jagged or corrugated design of the spray electrode or the spray plate. The tips of the spikes or the apexes of the waves are spaced from each other in the range of 2 to 10 cm.
- Spray electrodes or spray plates is promoted.
- the surface of the polymer solution or the polymer melt exposed to the environment is kept as small as possible, so that, for example, unnecessary solvent losses are avoided.
- the heat loss is kept low, which advantageously contributes to energy savings when operating the device according to the invention.
- the device according to the invention is closed or encapsulated with a lid such that only the at least one spraying electrode or the at least one spraying plate protrudes from the device. This advantageously further reduces the evaporation of solvents or cooling of the melt.
- the conveying device is formed by one or more lines or line systems for conveying the polymer solution or the polymer melt from the at least one storage vessel to the at least one spray electrode or the at least one spray plate.
- the one or more lines or line systems for conveying the polymer solution or the polymer melt from the at least one storage vessel to the at least one spray electrode or the at least one spray plate.
- the feed device is then actuated either in a predetermined time interval or controlled by an operator and the used spray electrode or the used spray element is released from the device according to the invention and a new spray electrode or a new spray plate is brought into an operating position for electrostatic spinning of a polymer.
- the particular advantage of this embodiment is that additional handling of solvents and a corresponding cleaning of the spray electrodes or spray plates can be omitted, as a result of which a higher level of operational safety is achieved, because the effort to completely clean the spray plates or
- Spray electrodes is comparatively large if the quality of the product, i.e. the fibers or nonwovens produced should be ensured.
- the counter electrode is preferably formed by a rigid sheet, an electrically conductive, circumferential band or a fleece. It is particularly preferred if the counter electrode is formed by an electrically conductive, circumferential band made of wire mesh or metal foil, this band moving in particular with a carrier material on which the fibers produced by the electrostatic spinning are placed. This avoids the application of tensile forces on the carrier material. It is most preferred if the counter electrode is formed from electrospun fibers of opposite polarity. This carrier material is then simultaneously coated on the top and bottom by two spray devices with fibers of opposite polarity. This creates a much more effective filter material, since a higher charge density can be achieved and both the positive and negative charges are firmly fixed in the fibers.
- water-soluble polymers e.g. Polyvinyl alcohol, polyvinyl pyrrolidine, polyethylene oxide and its copolymers, cellulose and its derivatives, starch and mixtures of these polymers.
- Polymers which are soluble in organic solvents can also be spun in the device according to the invention.
- Polystyrene, polycarbonate, polyvinyl chloride, polyacrylate, polymethacrylate, polyvinyl acetate, polyvinyl acetal, polyvinyl ether, polyurethane, polyamide, polysulfone, polyether sulfone, polyacrylonitrile, cellulose derivatives and mixtures of these polymers are particularly worth mentioning here.
- Polymers spinnable from the melt are e.g. Thermoplastics such as polyolefins, polyester, polyoxymethylene, polychlorotrifluoroethylene,
- Figure 2 is a schematic plan view of a conveyor roller with adjacent spray electrodes or spray plates;
- FIG. 3 is a schematic representation of an embodiment in which the
- Spray electrodes or spray plates are arranged on a transport device
- FIG. 4 shows a second embodiment of the present invention, in which the spray electrodes or spray plates are arranged on a transport wheel and pass through a cleaning bath;
- FIG. 1 shows a first embodiment of the device according to the invention for the electrostatic spinning of polymers.
- a conveyor device 1 formed by a conveyor roller is arranged in a storage container for the polymer solution or the polymer melt 2, the conveyor roller 1 conveying polymer solution or polymer melt from the storage vessel and transferring it to the adjacent spraying electrode 3, generally also referred to as a spraying plate.
- a high-voltage generator 4 generates the potential difference required between the spray electrode 3 and the counter electrode 5, so that the polymer contained in the storage vessel 2 is spun into fibers 6 in the electrostatic field.
- a 5% polystyrene solution in dichloromethane is mixed with 0.5 rhodamine G6 and spun at 50 revolutions of the conveyor roller (diameter 7 cm) per minute.
- the spray plates are directly opposite each other at a distance of 20 cm, the carrier fleece (micro-spunbond polypropylene fleece with 60 g / m 2 ) is in the middle at a speed of 0.5 m / min. passed.
- a high voltage of + or - 15 kV is applied to the spray plates.
- the carrier fleece coated in this way has a deposition rate of 50% of the 0.3-0.5 ⁇ m fraction of NaCl. Measured at a flow rate of 50 l / min. and a flow area of 100 cm 2 .
- the air resistance of the carrier fleece was increased under these conditions by the coating from 8 to 16 Pa.
