Definitions

  • the invention relates to a system for the continuous production of a spunbonded nonwoven web of aerodynamically stretched filaments made of thermoplastic material with a spinnerette, a cooling chamber, in the process air for cooling the filaments from an air supply cabin is inserted, a drawing unit with a Unterziehkanal.
  • process air refers to cooling air for cooling the filaments.
  • a known plant of the type mentioned ( DE 196 20 379 C2 ), from which the invention proceeds, has basically proven to produce a spunbonded web of aerodynamically drawn filaments.
  • the drafting unit is aerodynamically decoupled from a laying system that has a diffuser.
  • the Unterziehkanal is formed with respect to the gap thickness as the laying unit of the drafting aerodynamically decoupling barrier air shaft.
  • barrier duct means that during operation of the plant process air always exits the Unterziehkanal and enters the diffuser, but with a flow rate and a kinetic energy that prevents that pressure changes in the laying unit on the aerodynamic conditions in the Anblassystem or in the cooling chamber interfere with and vice versa. Therefore, in this system, the cooling process or blowing in the cooling chamber can be optimized without that this optimization interferes with the laying process and thus spunbonding disturbing. Conversely, the laying system can be optimized with regard to spunbonding without the turbulence system or cooling system being disturbed.
  • the arranged under the spinnerette cooling chamber of this system moreover, has a blowing fan, with which the process air is blown to cool the filaments to the filaments.
  • the invention addresses the technical problem of specifying a system of the type mentioned, with the higher filament speeds and increased Filamentfhen can be achieved and in which the problems described above can be effectively avoided.
  • the invention teaches a system for the continuous production of a spunbonded web of aerodynamically stretched filaments of thermoplastic material with a Spinnerette, a cooling chamber, in the process air for cooling the filaments from an air supply cabin is inserted, a drawing unit with a Unterziehkanal, where the stretching unit connects a laying unit with at least one diffuser and with a depositing device for depositing the filaments to the spunbonded web, wherein the air supply booth arranged next to the cooling chamber is subdivided into at least two cabin sections, from each of which process air of different temperature can be supplied and wherein the connection between the cooling chamber and the stretching unit is closed to the outside and formed air-free.
  • the air supply cabin consists of at least two cabin sections arranged vertically one above the other. Conveniently, only two cabin sections are arranged vertically one above the other.
  • process air at a temperature between 15 ° C and 75 ° C, preferably between 18 ° C and 70 ° C fed from a first cabin section and is from a second cabin section process air with a temperature between 15 ° C and 38 ° C, preferably between 18 ° C and 35 ° C fed.
  • the first and the second cabin section are arranged vertically one above the other and the first cabin section forms the upper cabin section and the second cabin section forms the lower cabin section.

  • the air supplied from the upper cabin section may also have a lower temperature than the air supplied from the lower cabin section.
  • at least one fan for the supply of process air is connected to each cabin section.
  • the temperature of each cabin section can be controlled. It remains within the framework of Invention, that the volume flows of the individual cabin sections of the supplied air streams can be controlled. By adjusting the volume flow and the temperature, in particular the upper cabin section, the cooling of the filaments can be reduced so that higher filament speeds are possible and finer filaments can be spun.
  • the air supply cabin is usually referred to as Anblaskabine.
  • a targeted blowing of the filaments or the filament bundle takes place with air.
  • no blowing of the filaments or of the filament bundle takes place.
  • the process air is sucked in by the filaments or by the filament curtain.
  • the filament bundle sucks in the process air it needs.
  • the cooling chamber corresponds to a passive system in which a blowing of the filaments does not take place, but only a suction of process air from the cabin sections.
  • a boundary layer of air forms concentrically around the individual filaments, and due to the structure of these boundary layers, the filaments suck or the filament bundle sucks in the process air.
  • the boundary layers ensure a sufficient distance between the filaments.
  • the spinnerette of the plant has nozzle bores for the exit of the filaments.
  • the mutual distance of the nozzle bores of the spinnerette in the middle of the spinnerette is greater than in the outer areas.
  • the distance of the nozzle holes in the nozzle plate of the spinnerette thus increases from the outside to the middle.
  • the air supply cabin arranged at a distance from the nozzle plate of the spinnerette is and that the air supply cabin is conveniently located a few inches below the nozzle plate.
  • a monomer suction device is arranged between the nozzle plate and the air supply cabin. The monomer suction device sucks air from the filament forming space directly below the nozzle plate, thereby allowing the gases exiting the polymer filaments, such as monomers, oligomers, decomposition products, and the like, to be removed from the plant.
  • the air flow below the nozzle plate can be controlled, which otherwise might not be stationary because of the indifferent conditions.
  • the Monomerabsaugungsvorraum expediently has an exhaust chamber to which preferably at least one suction fan is connected.
  • the suction chamber has a first suction slot towards the filament-forming space in its lower region.

As a result, nonwovens are obtained with optically high quality.
  • the invention is further based on the finding that for this solution of the technical problem an aerodynamic decoupling of the cooling of the filaments from the drawing of the filaments is required and that this aerodynamic decoupling can be achieved by realizing the described inventive features.

For aerodynamic decoupling but also contribute to the other above-described inventive measures.
  • the filament cooling functionally reliable from the filament drawing is decoupled or decoupled aerodynamically.
  • Aerodynamic decoupling here means that although pressure changes in the drafting unit have an effect on the conditions in the cooling chamber, this adjustment to the thread can largely be compensated for by the adjustment options in the split air feed.

  • the system according to the invention can have a laying unit without air guiding elements or without a diffuser. Then the filament-air mixture emerges from the drawing unit and, without the air-guiding elements, strikes the depositing device or the depositing screen belt directly.
  • the filaments are electrostatically influenced after exiting the stretching unit and are performed either by a static or dynamic field. The filaments are charged so that a mutual contact of the filaments is prevented. Conveniently, the filaments are then caused by a second electric field to a movement that has an optimal storage result.
