No. 657,250 Claims priority, application Germany, July 30, 1966, V 31,623; Aug. 31, 1966, V 31,829 Int. Cl. D06f 29/00.
  • the present disclosure relates to process and apparatus for the Wet-treatment of liquid-permeable materials.
  • the apparatus of the present disclosure comprises a liquid container containing a treatment bath, a conveying means at least partially immerged in said treatment bath, said conveying means communicating at its faces With at least one liquid-collecting compartment of said liquid container, inlet means for introducing the material to be treated to the conveying means, pump means for conveying the treatment liquid from the liquid-collecting compartment to the treatment bath and outlet means for removing the material from the apparatus.
  • the material to be treated is penetrated by the treatment liquid as a result of the level difference of the liquid outside the conveying means and the liquid inside the conveying means.
  • the present invention relates to a process and apparatus for the wet-treatment of liquid-permeable materials, such as needled felts, tufteds, nonwovens, woven and knitted fabrics, two, slivers and the like. More particularly, the present invention concerns the Washing and impregnating of running lengths of textile materials guided on a conveying means, preferably a sieve drum, which is penetrated by the treatment liquid.
  • a conveying means preferably a sieve drum
  • An object of the present invention is to avoid the prior art disadvantages in the wet-treatment of materials, particularly textile materials.
  • Another object of the present invention is to provide an apparatus which has the advantages of the known suction drum bowls and which is suitable for uniformly treating large working widths of about 3 to 5 m. and even up to about m. and higher. Such large working widths are required, for example, for carpet floor coverings.
  • a further object of the present invention is to provide an improved process and apparatus for the wet-treatment of textile materials wherein a more uniform and effective penetration of the material being treated by the treatment liquid is achieved.
  • the treatment effect can be increased if during the treatment the material is squeezed, preferably several times.
  • squeeze rollers which are distributed over the circumference of the drum can be synchronized to the sieve drum.
  • An intensification of the wet-treatment effect can also be achieved if the material is additionally subjected to a pulsating flow. This pulsating flow can be obtained by moving displacing elements or by causing the material length to flutter or to swing.
  • the design of the apparatus of the present invention wherein the material is penetrated solely by the level difference of the liquid outside the conveying means and the liquid inside the conveying means represents a substantial simplification over prior art devices and accordingly, is inexpensive when compared to prior art devices.
  • the apparatus of the present invention is provided with at least one liquid-permeable conveying means, preferably a sieve drum, and means which ensure a level difference between the liquor supplied to the material being treated and the liquor running off the material. This can be achieved by providing at least one bottom of the conveying means with at least one opening which permits the liquid which penetrates the material and flows into the conveying means to flow out of said conveying means.
  • the conveying means may be partially or completely immersed in the treatment bath.
  • a particularly effective design of the apparatus of the present invention can be obtained if the liquid container surrounding the conveying means and the liquid-collecting container are designed as one single container. This can be achieved by subdividing the liquid container surrounding the conveying means by at least one partition, which is sealed against the sieve drum, into a treatment compartment and at least one liquid-collecting compartment and by providing a pump which maintains a differential liquid level in the compartments of the liquid container which forces the liquid out of the liquid-collecting compartment or compartments into the treatment compartment.
  • the conveying means which preferably is a sieve drum, a partition means which is sealed against the conveying means so that the sieve drum may be provided at both sides with drain openings and so that the liquid may flow 3 into the two outer liquid collecting compartments of the liquid container.
  • a pump which conveys the treatment liquid which has flown out of the conveying means into the treatment compartment.
  • at least one pump preferably a vane-type pump is arranged in one opening of each partition.
  • a perforated jacket and/or a perforated trough around the conveying means in the treatment compartment and extended at a distance from said conveying means.
  • the perforated jacket is provided to avoid transverse currents near the material being treated.
  • the full pump capacity may not be required. Also, with very permeable materials, a smaller liquid level difference is sufiicient and only a small amount of pump capacity is necessary to convey the treatment liquid from the liquid-collecting compartment to the treatment bath. Small pump capacities can be achieved either by providing the pumps with a variable drive or by switching off one pump. In order to render it possible to switch off one pump in the case a two-sided liquid drain is provided out of the conveying means, it is suggested, according to the present invention, to connect the two liquid-collecting compartments of the liquid container by means of at least one compensating pipe means. If one pump is switched off, it is only necessary to close the suction opening of the pump. This can be accomplished, for example, by means of a cover which can be displaced in the axial direction on the pump shaft. Through the compensating pipe the liquid of both liquidcollecting compartments can be returned into the treatment compartment by means of only one pump.
  • the two pumps may be supported on one joint pump shaft to which a joint drive is synchronized. Especially when working with smaller working widths, it is advantageous to provide for a joint pump shaft. With large working widths, it is more advantageous to support each pump on a separate pump shaft and to provide it with a separate and/or variable drive.
  • the apparatus of the present invention can be used for washing out unfixed dyestuffs and auxiliary agents, and for the application of an impregnating liquid which, for example, may contain the substance to be cured for bonding needled felt carpets.
  • the apparatus is provided with at least one conveying means, preferably a sieve drum, which is completely or partially disposed outside of the treatment liquid.
  • the material to be treated is guided over the upper portion of the conveying means which is situated outside the treatment liquid and i sprayed with the treatment liquid by a spraying, jetting or sprinkling device. Using this type of treatment, a good and uniform penetration of the material by the liquid is ensured.
  • the device for sprinkling the materal may comprise, for example, a container with at least a partially perforated bottom, the perforations extending over substantially the whole working width of the conveying means disposed therebelow.
  • several squeeze rollers may be provided at the surface of the conveying means and synchronized to said conveying means to intensify the liquid penetration of the material by squeezing and thus to correspondingly increase the treatment effect.
  • Another eifective arrangement of the apparatus according to the present invention comprises a sieve drum or another conveying means which is partially immersed in the treatment liquid, in which apparatus the conveying means is substantially embraced by the material to be processed so that the part of the conveying means which is situated outside of the treatment liquid as well as the part of the conveying means which is situated in the treatment liquid is covered with the material being treated.
  • a conveying means for example, a sieve drum, which is only partially immersed in the treatment liquid.
  • a conveying means for example, a sieve drum
  • liquid displacing elements are arranged above the conveying means.
  • the surface of the displacing element directed toward the material length is designed in such a way that a current is produced toward said material.
  • This can be achieved, for example, by providing the displacing element with a step-type surface which extends toward the material being treated.
  • Such a displacing element may also be arranged between the portion of the material length being fed to the apparatus and the portion being discharged where the material is freely guided in the treatment liquid. Similarly with this displacement element, it is advantageous to profilate the surfaces of said element directed toward the material length.
  • a pulsating flow toward the material length which is guided in the treatment liquid can be obtained if the displacing element which is disposed between two portions of the material length is moved in a vibrating or swinging fashion. It is also possible to obtain a pulsating flow at that portion of the material length being fed to the conveying means and at that portion being discharged from the conveying means by utilizing moving elements which act upon the material length, for example, a beater roll. By means of these elements, the material length is caused to swing or vibrate so that a pulsating alternate flow is obtained by the motion of the material length.
