Definitions

  • the invention relates to a method and a device for impregnating a fiber material with an impregnating agent containing as a solution or an emulsion at least one additive.
  • Such methods are used to impregnate any fibrous materials, which may be synthetic or natural fibers, with additives which serve to formulate certain performance characteristics of the fibrous material.
  • additives are used to make the fibers of the fiber material flame resistant or to protect against fungal or bacterial attack.
  • dip impregnation the mats are flooded with the liquid impregnating agent. Natural fibers especially absorb the liquid. The mats must therefore be subsequently dried consuming to ensure storage stability. This method is therefore uneconomical.
  • the object of the invention is to provide a method and an apparatus for impregnating a fiber material with an impregnating agent, in which a substantially homogeneously distributed impregnation of the fibers is achieved.
  • the guided past the mixing heads and this at least partially surrounding fiber material with the help of the mixing heads in a region around the mixing heads around loosened locally and treated with the impregnating agent by the impregnating agent is introduced by means of the mixing heads via one or more nozzles in the locally loosened fiber material whereby the impregnating agent is distributed substantially homogeneously over the fibers of the fibrous material; and applying the impregnating agent

  • the impregnating agent is preferably applied with a pressure for dispensing, so that the impregnating agent is sprayed.
  • the impregnating agent is distributed to save material and evenly over the fibers to be impregnated. This is achieved in particular by the fact that the fiber material is dissolved prior to introduction into the working space, which is preferably carried out to the separation of the fiber material, and with the help of the mixing heads a local loosening of the fiber material is performed, so that a felting of the fiber material is avoided , In this way, the introduced impregnating material meets a loosened fiber material, in which hardly any shadow effect of fibers compared to other fibers occurs.
  • the impregnating agent is introduced directly into the loosened fiber material. Losses that occur when impregnating is not introduced into the fiber material, but for example on the inner wall of the working space, are avoided. This also ensures that as little additive as possible must be used to impregnate the fiber material. In this way, the method contributes to cost savings.
  • the avoidance of the unintentional distribution of impregnating agent on the inner regions of the working space further contributes to the fact that the wear of the system is reduced because less contamination of the components occurs in the working space. Therefore, the cleaning intervals can be extended.
  • the deposition of impregnating agent on such components may also cause damage to these components, for example due to the chemically aggressive effect of the additive.
  • An expedient embodiment of the invention provides that the impregnating agent as a highly concentrated solution / emulsion of the at least one additive on the one or all nozzles is introduced.
  • the impregnating agent as a highly concentrated solution / emulsion of the at least one additive on the one or all nozzles is introduced.

  • a targeted and material-saving use of the additive is achieved in one embodiment of the invention in that an amount of sprayed with the impregnating at least one additive in dependence on a solids content of the metered amounts of introduced in the working space dissolved fiber material is determined.
  • the procedure is preferably such that the weight of the solid of the fiber material is determined on the basis of a weighing and then the amount of additive is determined which is necessary to achieve a desired impregnation of the fiber material.
  • Such a process design in turn supports an efficient use of the at least one additive.
  • any additives can be distributed substantially homogeneously over the fibers to be impregnated with the aid of the method.
  • the invention can be provided that are introduced along the conveying path via the mixing heads impregnating agent with various additives. In this way, a successively carried out impregnation of the fiber material with different additives is possible.

  • the fiber material surrounding the mixing heads is locally loosened up with a rotating loosening device formed on the mixing heads in the area around the mixing heads.
  • the rotary loosening device on the mixing heads is preferably formed by means of a rotating member having a circumferential length which is greater than an elongated length of the longest fibers covered by the fiber material to be impregnated.
  • the local loosening of the fiber material for spraying the impregnating agent is preferably achieved in that the rotating loosening device rotates at high speed at the mixing heads at a speed of about 500 to 3000 revolutions per minute, preferably at a speed of about 1,000 to 3,000 revolutions per minute, more preferably at a speed of about 1,500 to 3,000 revolutions per minute.
  • an embodiment of the invention provides that the introduced fiber material in the working space along the conveying path conveyed by means of entrainment tools encompassed by the conveying and mixing device mounted on a shaft disposed in the working space and rotated with the shaft to convey the introduced fiber material from the inlet to the outlet.
  • a shaft having a circumferential length which is greater than a stretched length of the longest of the fiber material to be impregnated fibers This prevents that the fibers of the fiber material to be impregnated wrap around the shaft or there is an increased entanglement of the fiber material.

Based on the information about the determined ground moisture of the metered fiber material, the amount of solvents can be determined, which is introduced via the mixing heads, so that the treated fiber material then has a predetermined total moisture. Compliance with the predetermined total moisture can be checked with the help of further moisture analysis. In addition, the information about the total moisture of the discharged fiber material can be used to decide on an optional, the impregnation downstream drying of the discharged fiber material. In particular, it can be determined whether and, if appropriate, to what extent post-drying is necessary.

This information is used to determine an amount of additive which is sprayed after introduction of the metered amount via the inlet 3 for impregnating the introduced amount of fiber material with the liquid impregnating agent.
