Definitions

  • the invention relates to a device for producing Spunbonded nonwovens, that is to say of flat structures, which are characterized by a large number endless filaments are formed. These filaments are created by Spinning or extruding molten plastics in Devices containing numerous nozzles in which the Plastic is formed into the filaments and discharged. Of the Cohesion of the spunbonded nonwovens can be explained by the more or less strong connection of the filaments to each other at their mutual crossing points.
  • the invention deals in detail with spinneret packages for Manufacture of spunbonded nonwovens. These nonwovens consist of two at least in terms of their melting range, by Continuous filaments connected by heat. These in turn arise from simultaneous extrusion of two different ones in their melting range Polymer and then put together on a flat surface mixed with each other.
  • the resulting fabric is heated in the next step a temperature which only softens one type of filament, so that at all crossing points of the two filament types and at the Crossing points of the lower melting filaments with each other each time there is an adhesive connection after cooling.
  • the filaments with a lower melting point therefore play the role of the binder.
  • the nonwoven fabric is produced by pressing the two melted polymer types for the respective filaments Spinnerets through, which are arranged side by side, whereby each of a polymer type a spinneret physically and in terms of Material and temperature control is assigned.
  • the spun Filament bundles become pneumatic from one side below the nozzles stretched and hit a baffle or baffle, which the opening of the bundle. After that, the filaments fall onto an endless one Batten cloth. Alternatively, they can be combined and only then together be stretched pneumatically. This is a particularly good one Mixing of both filament types achieved.
  • a needle process is expediently followed, also continuously, by the thermal calendering.
  • the fabric passes through the linear gap between two cylindrical rollers, at least one of which is heated.
  • a temperature is selected which only softens the lower melting filaments to such an extent that it becomes capable of the binding at the filament crossing points described above.
  • the solidified fabric is cooled between cooling cylinders and then wound up.
  • the finished nonwovens according to DE-C2 34 19 675 have basis weights of 100 to 180 g / m 2 .
  • Examples are carriers for Called carpets, where the fibers are sufficiently flexible during the tufting process such a good adhesive connection to produce in the finished carpet that there are no loose fibers.
  • roof sheeting which is used for bituminizing Temperatures of up to 220 ° C are exposed and below these Conditions are subject to tensile stress.
  • the Longitudinal strain in the direction of stress is not 5% of the initial value exceed.
  • the solution to the task is to provide and operate Spinnerets, each capable of doing so, are two types of thermoplastic Polymers to filaments with different titers and with around 5 to To spin 50 ° C different melt temperatures.
  • the distances between the different polymers Drill holes as well as the choice of solid or air insulating material depend from the specific different melt temperatures of the two Types of polymers. A number of easy to do Preliminary tests are therefore essential in order to achieve the best results for both polymers optimal, adapted to the respective melt temperature Set temperature control. Of course, that plays in particular Melting point difference plays a role here.
  • solid insulating materials are ceramic masses or with Phenolic or epoxy resin soaked and hardened glass fabric mats.
  • the matrix fibers and the binding fibers have different titers should have the holes for the production of the finer
  • the cross section of the fibers must of course be so narrow that a lower throughput and thus finer filaments can be achieved than in the parallel tied, higher titer filaments.
  • the advantage of the invention is that for the first time in the tightest Space very many and also regarding the type of polymer and the Different filaments can be extruded. This results in premixing of the shortly after the nozzle emerges Types of fibers with each other, whereby downstream mixing devices for the spun filaments can be saved. A segregation in further removal of the spinnerets is excluded.
  • FIG. 1a shows the arrangement of a spinning unit assembly in a side view, starting from above with the spinneret pack 1 and the cooling air 2 blowing transversely to the spinning direction.
  • the high-melting matrix filament is designated 3, the low-melting binding filament 4.
  • Both filaments pass through a stretching element 5 and then get into a cooling cabinet 6. From this, both filament types 3 and 4, spreading in a conical shape, are ejected and deposited on a storage belt 19 that moves horizontally in the direction of the arrow.
  • the filaments can be deposited on the sand by suction devices located below the belt.
  • the arrow demonstrates the direction of the conveyor belt perpendicular to the plane of the drawing.
  • Figure 1b shows the bottom view of the spinneret packs 1.
  • the outlet holes 7 for the binding filaments and To see outlet holes 8 for the matrix filaments, also the Heating box 9.
  • FIG 2a and b show different arrangements for the Exit holes of the filaments in rectangular spinneret packages.
  • the exit holes for the binding filaments are again 7, those for the matrix filaments designated 8.
  • Each Spinneret pack 1 is surrounded by a heating box 9.
  • the analog 2c and d relate to round spinneret packs 1.
  • Figure 2a and c are the exit bores 7 and 8, respectively summarized, in variant a to materially separated from each other Rows, in variant c in separate materials, concentric circles. An even distribution of the holes 7 and 8 with each other is shown in Figures 2b and d.
  • a spinneret 1 is shown from below, which Exit bores 8 for the matrix filaments and exit bores 7 for which contains binding filaments.
  • the heater box is again designated 9.
  • Between the melt channels for the matrix filaments and those for the binding filaments are insulating holes 10; furthermore are the Channels (only the outlet holes can be seen from below) for the Binding filaments surrounded by an insulating gap 11.
  • the insulation material in the cavities 10 and 11 can be a solid material; However, it is filling with air is also possible.
  • the insulating gap 11 serves the Reduction of the heat flow from the heating box 9 to the Melt channels.
  • Figure 3b shows an analog arrangement with a round nozzle concentric outlet bores 7 and 8. Since the bores 7 for the Binding filaments linearly far enough from the cylindrical one here Heating box 9 arranged and this additionally by the Positioning of the melt channels and outlet holes 8 for the Matrix filaments are isolated, this design eliminates the need an additional insulating gap according to Figure 3a.
  • the insulating cavities 10 and 11 are arranged in the nozzle that their mechanical stability does not suffer any losses.
  • the insulating holes 10 separate the Melt channel 12 for the polymer of the matrix component of the Melt channel 13 for the polymer of the binding component. Shortly before the Each of the melts passes through a melt distribution screen 14 and then a pilot hole for the nozzle outlet capillary 16. The constructive structure for the grounding of the binding component is identical.
  • Figure 5 shows the possible melt flow using a rectangular Spinneret pack. With a hole arrangement according to FIG thermal separation of the polymers for the matrix filaments and Binding filaments such that the latter through cannulas 18th is directed. These are from a filled with air or insulating material Annular gap 17 surrounded. The top of the channels are Insulating holes 10 and insulating gaps 11 are available. The cross section B - B 5a shows these conditions in FIG. 5b.
  • the material guide is chosen so that the filaments obtained in the distribution 90% polyethylene terephthalate and 10% copolyester available.
  • the titer of the polyethylene terephthalate threads is 9 dtex.
  • the two sets of filaments are combined underneath the nozzle and after stretching together in a stretching unit on a sieve-like, horizontally moving conveyor belt placed in confusion. That so Loose non-woven is created in a calender by means of two steel rollers under a pressure of 3 t at a speed of 20 m / min pre-consolidated, with both rollers heated to 120 ° C.
  • the top roller has an engraved surface.
  • the fleece is sprayed with a silicone-containing finish and in a continuous furnace at 195 ° C by melting the binding fibers finally consolidated.
  • Both sets of threads per nozzle are combined and in the drawing unit stretched together. Then it is stored on a sieve-like, horizontally moving conveyor belt. The resulting loose Fleece is placed in a calender by means of two steel rollers under one Pressure of 5 t pre-consolidated at a speed of 15 m / min. Both Rollers are heated to 150 ° C, one of which is engraved Surface. The final consolidation of the fleece takes place in one Continuous furnace at 230 ° C, in which the binding fibers melted slightly become.
  • Extrusion is carried out through spinnerets in the configuration in FIG. 3 and in the arrangement according to FIG. 1 each made of 200 filaments Polyethylene terephthalate and 90 filaments from one Polyethylene terephthalate copolymers, the melting range of which 165 ° C.
  • the nozzle temperature for the polyethylene terephthalate is 290 ° C, for the polyethylene terephthalate copolymer 220 ° C.
