Definitions

  • the present invention relates to a new and improved working process for an impregnation liquid for the continuous treatment of a textile fiber band or arrangement.
  • FIG. 1 is a schematic view of apparatus for carrying out the inventive working process.
  • FIG. 2 illustrates a portion of the apparatus depicted in FIG. 1.
  • the impregnated fiber band 6 While undergoing continuous processing the impregnated fiber band 6 is introduced without contact through aninlet opening 7 into a closed and heat-insulated compartment or chamber 8.
  • the impregnated fiber band again leavesthis compartment 8 after a certain treatment time in the form of -a treated fiber band 10, departure from the compartment 8 being through a narrow outlet opening 9.
  • the treated fiber band 10 can be then, for instance, subsequently wound upon a bobbin or thelike.
  • the feeding of the band 6 in the closed compartment 8 is in the direction of the indicated arrows and there can be used for this purpose any suitable means which have therefore not been particularly shownrAlso contained within the closed compartment 8 is a conventional and thus not particularly illustrated heat source and, if desired, means for circulating the treatment medium.
  • the infeed of coolant takes place through the agency of the infeed line or conduit 16, the discharge of such coolant from the condenser 17 occurs through the agency of the removal or withdrawal line 18.
  • a vent line 19 isprovided for the condenser 17 at the inlet side of the cooling medium.
  • a throttle mechanism 20 is located in the vent line or conduit 19 and such is operatively associated with a ventilator or fan 21.
  • the vapor escaping intothe condensation compartment 12 condensates with a corresponding reduction in volume, whereas the non-condensating constituents, for instance air, are continuouslyremoved via the vent or withdrawal conduit 19.
  • a specific aspect of the invention resides in the fact that between the closed compartment 8 which is essentially at atmospheric pressure and the condensation compartment 12 there prevails a pressure difference.
  • This pressure differential can be determined in such a manner that at the inlet opening 7 the contactless incoming fiber band 6 automatically also sucks-in ambient or surrounding air, as indicated by the associated arrows of FIG. 1, and which completely closes the vapor atmosphere flowing into the connection channel 11 towards the surroundings or ambient space.
  • This can be realized by accommodating or adjusting the conveying output of the ventilator or fan 21, but it is also possible to adjust or regulate the negative pressure for a given conveying output of the ventilator 21 by means of the throttle mechanism 20.
  • the quantity of air sucked-in at the inlet opening 7 is preferably maintained at a minimum, that is to say, there is for instance only ensured for absolute closure of the vapor atmosphere moving through the connection channel 11 from the surroundings.
  • the condensate deposited in .the container 15 can, while taking into account the different material concentrations and possible decomposition products, again be readily employed for preparing a similar impregnation liquid, once again decisively contributing to polution-abatement of the environment.
  • impregnation liquids for instance containing toxic or in fact poisonous chemicals, for example swelling agents, organic solvents or the like and for subjecting such to a high temperature in a treatment compartment devoid of seals without for instance contaminating or endangering in any way the surroundings or the operating personnel.
  • the employed condensation technique it is possible, for instance, to afford a continuous reuse of the required solvent and in part also the chemicals, to reduce to a minimum the basic consumption of such components, and to extensively free from contaminants the waste air ejected for instance into the surroundings.
  • the impregnation liquid is concerned there is provided a practically completely closed system. Hence, process conditions can be realized which, for instance, correspond to the highest ecological requirements.
  • a working process for an impregnation liquid for continuous treatment of a textile fiber band or the like comprising the steps of introducing the impregnation liquid into a fiber arrangement, delivering an impregnated fiber band, introducing the fiber band into a heated closed compartment which is essentially at atmospheric pressure, heating the impregnated fiber band, vaporizing the impregnation liquid, removing the vapor atmosphere from the closed compartment, and condensing the vapor atmosphere in a condensation compartment which is at a pressure differential with regard to the closed compartment.
