Definitions

  • the invention relates to a method for strengthening fiber and / or filament nonwovens by exposing the fleece to jets of gaseous media for the production of binder-free, light and absorbent nonwovens.
  • the object of the invention is to provide a method in which the use of gaseous Working media for consolidating nonwovens with a significantly higher connection effect and a more effective production of consolidated nonwovens compared to the prior art enables.
  • gaseous working media compared to hydroentangling a simplification of the process design by eliminating the drying of nonwovens and water treatment and thus a saving in energy expenditure reached.
  • FIG. 1 The principle of the process of nonwoven bonding using gaseous media is shown in FIG. 1 shown.
  • the fiber and / or filament fleece to be consolidated becomes permeable Transport device, which is covered with a wire mesh, fed to the nozzle bar. It is also possible to feed the fleece between two wire meshes.
  • the nozzle bar contains a large number of nozzle bores, their cross section over the entire nozzle length is constant or is reduced towards the nozzle outlet, i.e. the smallest nozzle cross section is located at the nozzle outlet.
  • a slot die can also be used. Air or water vapor is supplied to the nozzle bar as the working medium, the Pressure and temperature are constantly monitored.
  • the gas jet When using gaseous media for nonwoven bonding, the gas jet also flows Speed of sound from the nozzle when the narrowest nozzle cross-section on Nozzle outlet is located. Print; The density and temperature in the exiting gas jet decrease so-called critical values resulting from the physical conditions at rest derive.
  • a polyester fiber fleece with a mass per unit area of 40 g / m 2 is subjected to compressed air jets emerging from nozzle bores.
  • the holes are 1mm apart and are designed so that the narrowest nozzle cross-section is at the nozzle outlet.
  • the bore diameter is 0.1 mm at the narrowest point.
  • the air jets emerging from the nozzles reach a speed of 320 m / s. According to the set resting pressure, the air jets have a density of 37 kg / m 3 and the critical pressure is about 27 bar.
  • average specific strengths of approx. 2.5 Nm 2 / g are achieved.
  • the fleece structure before and after consolidation is shown in FIG. 2.
  • a polypropylene fiber fleece with a mass per unit area of 80 g / m 2 which can also be mixed with low-melting binder fibers, is subjected to superheated steam at a resting pressure of 10 bar and a resting temperature of 495 ° K.
  • the steam reaches a critical speed of 570 m / s when flowing through the nozzles.
  • the density of the compressed gas jets is 2.15 kg / m 3 .
  • the fleece is consolidated (Fig. 3), the average specific strength is 2.2-2.8 Nm 2 / g. It is not necessary to dry the nonwoven because, despite the cooling that occurs when the steam expands when it passes through the nozzles, the saturated steam temperature associated with the critical pressure is not fallen below.
