Definitions

  • the invention relates to a method for preventing the bonding of nonwoven material according to the preamble of patent claim 1.
  • the invention further relates to a device for preventing the bonding of nonwoven material according to the preamble of patent claim 5.
  • Nonwoven material such as wadding, nonwovens, and the like, are prepared by adding fusible fibers or fibers having a meltable surface to enhance cohesion and volume retention.
  • the felts enriched with fusible fibers are heat treated in an oven. It can not be avoided during this process (heat treatment) that individual fusible fibers, which are located on the surface of the web, with the conveyor belt on which they lie and come into contact.
  • An object of the present invention is to provide a method and an apparatus with which the adhesion of the melt fibers to the conveyor belt can be prevented.
  • melt fibers on the nonwoven surface in the short term so to heat strongly so that they contract or curl under the action of heat and no longer come into contact with the conveyor belt when subjected to the heat treatment in the heating zone.
  • Figure 1 is a vertical section through a

  • a bonding furnace 1 of known design shown schematically by a rectangle, at least one conveyor belt 3, preferably a belt made of latticed material, can be seen. This is guided around a plurality of deflection rollers 5, wherein the deflection rollers 5 are located outside the bonding furnace, but at least outside a heat zone 7 arranged in the bonding furnace 1.
  • the heat zone 7 may comprise a number of nozzles, through which ' hot air through the conveyor belt 3 through to a nonwoven material 9 and through this is passed.
  • an extraction takes place by means of suitably arranged suction nozzles.
  • the application of hot air can also be done in sections from top to bottom and bottom to top (no illustration).
  • a suitable heat source 11 is arranged below the conveyor belt 3.
  • the heat source 11 extends over the entire width of the conveyor belt or of the nonwoven material 9 lying on the conveyor belt and conveyed by it.
  • the nonwoven material 9 is passed in the example described from the left side of Figure 1 on the conveyor belt 3 and it leaves the latter on the right side.
  • a high temperature can be achieved and by the heat radiation located on the surface of the nonwoven material 9 melt fibers, ie the side facing the conveyor belt during the passage of the heat source 11 are briefly strongly heated.

  • the heat source 11 may generate radiant heat, or hot air may be blown onto the nonwoven surface through a slot die (not shown). If a slot nozzle is used, it can additionally be achieved that the nonwoven material 9 is lifted slightly off the conveyor belt 3 during the shock-like heat treatment, and the melting fibers 13 do not touch the belt 3 during contraction.

  • the fusible fibers 13 Prior to the high temperature shock-like heat treatment over the heat source 11, the fusible fibers 13 are finely dispersed in the nonwoven material 9. Individual fibers 13 and 15 protrude beyond the surfaces of the nonwoven material 9. However, as soon as they have passed the region of the heat source 11, the melt fibers 13 have contracted due to the thermal shock and no longer project beyond the surface of the nonwoven material 9 (right side of FIG. 2).

Abstract

Pour empêcher l'adhérence de fibres fusibles (13) d'un matériau non tissé (9) à la bande de transport (3) pendant l'opération de liaison dans un four de liaison (1), la surface du matériau non tissé (9) est brièvement chauffée à haute température avant et/ou après l'entrée du matériau non tissé (9) dans la zone de chauffe (7) du four de liaison (1). Grâce à la chauffe brusque de la surface du matériau non tissé (9), les fibres fusibles sont rétractées dans le matériau non tissé (9) et/ou frisées, ce qui empêche qu'elles adhèrent à la bande de transport (3).
