Definitions
- the invention relates to a process for the production of fibrous materials from thermoplastic materials, in which the thermoplastic material is melted and passed into a rotating reactor to form a melt film and the fibers are formed and stretched on an open reactor edge.
- the invention further relates to a device for producing fibrous materials from thermoplastic materials with a melting device for the thermoplastic material and a heated rotating reactor for forming a melt film from the molten plastic, which leaves the rotating reactor via an edge of an open side with the formation of fibers.
- Nonwovens formed from such fibrous materials are used in particular for the absorption of petroleum, petroleum products and heavy metal ions from water.
- thermoplastic fibers The usual way of producing thermoplastic fibers is by melting the starting thermoplastic and extruding the molten plastic through thin nozzles to form thin radiation-like fibers.
- the extruded fibers can be made even thinner, while at the same time they are cooled with a special air flow.
- These processes require a very homogeneous starting thermoplastic, so that in particular the use of recycled plastics is inhomogeneous are and may contain foreign objects. This would clog the nozzles or channels.
- the extrusion processes also provide that relatively low temperatures, which can be only slightly above the melting temperature, are used in order to make the cooling measures after the extrusion as simple as possible.
- the processing of secondary raw materials and thermoplastic waste requires processing at higher temperatures that are close to the temperatures of the thermoplastic decomposition.
- thermoplastic melt to a rotary pot, on the inner wall of which the melt film is formed and the spin-stretching from the melt film is carried out by the formation of fibers on the edge of the pot at a gas which is passed over the melt film at high speed.
- the reactor is designed in the form of a vertical pot and consists of a cavity and a work surface. Heated gas is fed under pressure to the internal cavity of the reactor and the surface of the melt film. There are slot nozzles on the edge of the pot, through which the melt film is divided into individual jets and flows together with the heated gas. As a result, the rays formed are made thinner and stretched.
- the invention is based on the object, while avoiding the disadvantages of the known device, of being able to produce thin synthetic fibers which can be formed with higher yield from high-quality raw materials, but also from waste thermoplastics.
- a method of the type mentioned at the outset is characterized in that the rotating reactor is heated in such a way that the melt film has a temperature close to the decomposition temperature of the thermoplastic and that the reactor is equipped with a Web speed of at least 10 m / s is rotated on its edge.
- the reactor itself is thus heated, so that the molten thermoplastic is subject to very constant temperature conditions which can be selected for the thermoplastic near the degradation temperature, without the risk that the quality of the plastic is impaired by decomposition processes if this temperature is exceeded locally becomes.
- fiber formation occurs due to the high rotational speed or the high web speed at the edge of the reactor, as a result of which the cohesive force of the melt film is exceeded, so that the fibers are divided.
- the use of channels or nozzles prone to blockage can therefore be dispensed with entirely.
- the fibers stretched at the edge of the rotary pot are expediently stabilized under the action of an air stream, which is preferably conducted transversely to the fiber path.
- the thermal uniformity in the reactor required for the process according to the invention is supported in a preferred embodiment in that the interior of the reactor is largely closed off by a cover which forms a narrow circumferential gap with the edge.
- the gases emerging during the heating of the melt film emerge through the gap and have a positive influence on the fiber formation according to the invention.
- the lid is preferably positioned stationary. It may be expedient if the cover is positioned asymmetrically to the axis of rotation of the reactor to form a circumferential gap with a varying width.
- melt film of spiral streaks i.e. uneven thicknesses. This can largely be prevented be that the melt film on the inner wall of the reactor is divided by axially extending ribs.
- a device of the type mentioned at the outset is further characterized according to the invention in that the rotating reactor is heated from the outside and is closed on its open side by a fixed cover except for a circumferential annular gap formed with the edge.
- the inner wall of the rotating reactor widens conically towards the edge, although the reactor can be cylindrical over most of its axial length.
- the annular gap can preferably have a width of 15 to 20 mm, it being possible for the annular gap to be formed with a varying width by a cover arranged asymmetrically to the axis of rotation of the rotating reactor.
- the inner wall of the reactor is provided with axially extending ribs for dividing the melt film, these are preferably triangular with their greatest height at the bottom of the reactor and with their lowest height at the outlet end of the melt film.
- the ribs preferably extend over the cylindrical part of the reactor and end at the beginning of the conical part.
- the reactor is brought to its operating temperature from the outside by a heater, which can preferably be a resistance heater, an induction heater or a magnetic induction heater.
- a heater which can preferably be a resistance heater, an induction heater or a magnetic induction heater.

- the drive motor 40 brings the worm 43 into rotation via the belt drive 41 and the reduction gear 42.
- the screw 43 grips the thermoplastic from the container 39 and conveys it to the feed head 11.
- the material As the material is conveyed through the heated part of the extruder 11, it mixes and melts to a viscosity which corresponds to the thermoplastic viscosity in the region of the degradation temperature.
- the molten material then enters the reactor 5 through the opening 24 of the attachment 23 and the feed head 11, where the same temperatures are maintained.
- the melt is distributed over the circumference of the inner wall and, thanks to the centrifugal force, is transported between the ribs 13 to the open end of the reactor 5.
- the melt By advancing the thermoplastic layer touching the inner surface and the ribs 13, it additionally rises, whereby a thin melt film is produced.
- the ribs 13 are installed inside the reactor 5, the melt does not move in a spiral, which would happen with a smooth surface, but along the end of the reactor.
- the inner surface is coated with the melt film much more uniformly, which significantly increases the quality of the melt.
- the melt film reaches the region of the conically widened cone 7 from the cylindrical part of the reactor 5, its thickness is additionally reduced.
- the production of the fibrous material in the manner according to the invention is only possible if the linear velocity at the cone edge of the reactor 5 is higher than 10 m / s.
- the air flow 44 flowing out of the openings 15 of the ring air line 14 influences the fibrous material in the process of stretching.
- the fibrous material arrives on the assembly line 45 of the unit for fiber precipitation 3. With the aid of the assembly line 45, the fibrous material is conveyed to the removal device 4, where the fibers are shaped into finished goods.
- the gases produced during the production of the fibrous material are passed from the protective chamber 33 through the air channels 34 and 36 with the aid of the low pressure fan 35 into the gas cleaning device 37.
- the device described enables the production of the fibrous material from thermoplastics with excellent absorption properties, whereby industrial and household waste can also be used as a raw material.
- the reactor heater 6, which is constructed on the outside of the reactor 5, can be designed as a resistance heater 25, induction heater 26 or as a magnetic induction heater.
- these heaters 25, 26 and the reactor 5 with the outer jacket 27 are thermally insulated.
- the reactor heater 6 is designed as a resistance heater 25, which is located in a heat-resistant ceramic solid housing 28. Between the electrical heater and the protective jacket 27 is a heat insulating material 29, such as kaolin cotton, housed.

- the starting raw material is premelted in the extruder 1 and stirred, so that a homogeneous melt is formed, the temperature of which is close to the degradation temperature of the polymer.
- the melt is fed from the extruder 1 to the rotating reactor 5, the wall temperature of which is preheated to a temperature close to the degradation temperature.
- the melt is distributed evenly on the inner surface by the rotation of the reactor 5.
- a paraboloid of the rotation is formed, and it moves towards the open side under the influence of centrifugal forces. Since the open side of the reactor 5 is in the form of a diverging cone 7, the thickness of the film decreases in proportion to the enlargement of the side surface. In this way it is possible to get thinner fibers.
- the film After leaving the edge of the diverging cone 7, the film divides into individual jets which become fiber under the action of the centrifugal force and due to a high rotational speed of the reactor 5.
- the resulting fiber comes into the air flow 44, which is directed perpendicular to the fibers flying apart and thus forces the fibers into the unit 4 for the fibers to be removed.
- the fiber lengthens and cools. Since the process of film formation takes place in a practically closed space, a gas medium with an overpressure is created within the reactor 5. This can reduce degradation processes due to lack of air.
- the use of the method according to the invention makes it possible to carry out high-quality fibers not only with raw materials of one type, but also with a combination of raw materials. This is because the raw material is first melted down and stirred in the extruder 1 and then remains within the reactor 5 for a certain time. As a result, the entire amount is heated uniformly and the viscosity is averaged so that the fiber is produced from a homogenized melt.
- the reactor 5 In the event of a malfunction, as a result of which the melt does not reach the required viscosity, the reactor 5 is self-cleaning under the action of the centrifugal force.
- thermal stabilizers in dendritic form, which has free ions, enables rapid suppression of the processes during the degradation of polymers by bringing together free radicals of the broken polymer chains. This results in an increase in the amount of fibers compared to heavy metals, and the emission of pollutants into the environment is reduced.
