Definitions

  • the present invention relates to a process and apparatus for the wet-treatment of materials, for example, textile materials, wherein the material to be treated is penetrated at least twice by the treatment liquid.
  • the present invention concerns the wet-treatment of textile materials such as for example, loose fibrous material, tow, top, slivers, fabrics, knit goods, needled felt materials, non-woven, tufted carpets, etc., wherein the materials to be treated are introduced into a liquid treatment bath, immersed in said treatment bath by contact with at least one conveying surface, and penetrated at least twice by the treatment liquid in alternate directions as a result of passing a portion of the treatment liquid into and out of the conveying means providing the conveying surface.
  • textile materials such as for example, loose fibrous material, tow, top, slivers, fabrics, knit goods, needled felt materials, non-woven, tufted carpets, etc.
  • Perforated rollers subjected to a suction draft have also been used for securing wool.
  • at least two perforated rollers are arranged in the treatment bath and between these two rollers a floating zone for the loose wool is provided.
  • the liquid which is laterally discharged from the perforated rollers is returned into the bath beneath the perforated intermediate bottom.
  • undesirable turbulence is produced in the bath which prevents settling of the dirt. If the liquor is very contaminated, the loose fibrous material can act as a filter, so that part of the dirt is again deposited on the fibrous material.
  • Another object of the present invention is to provide an improved process and apparatus for a more uniform wet-treatment of materials, such as for example, textile materials, with large working widths.
  • a further object of the present invention is to provide an improved process and apparatus for improving and increasing the wet-treatment effect, that is, the general cleaning eifect per liquid circulation cycle.
  • a still further object of the present invention is to provide an improved process and apparatus for the wet-treatment of textile materials wherein small particles carried along in the treatment liquid, for example, dirt, is prevented from settling and sticking to said textile material.
  • the present invention not only is a double treatment effect ob-- tained in one liquid circulation cycle, but also particles which may have deposited on the material when the treatment liquid is drawn into the perforated roller are again detached from the material when it is penetrated by the treatment liquid flowing in the opposite direction.
  • a perforated conveying means for example, a perforated roller
  • said roller contains a pumping device and in some cases guiding elements which are arranged in such a manner that at least a portion of the interior of said roller is divided into a suction zone and a pressure zone.
  • the pumping device outside of the perforated roller, to exhaust the treatment liquid at one face of the suction zone and to return the liquid at the same face into the pressure zone.
  • the material to be treated can be stressed in the longitudinal direction, it is passed around the perforated roller to the extent that in each circulation cycle it is penetrated twice and alternately by the circulating treatment liquid.
  • a pressure roller so that it engages the material being conveyed on the outside of the perforated roller at the transition point between the suction zone and the pressure zone.
  • the flow of the treatment liquid is obtained by providing a pumping means, for example, a gear pump or a cross-current pump in the conveying means, for example, a sieve drum.
  • a pumping means for example, a gear pump or a cross-current pump in the conveying means, for example, a sieve drum.
  • At least one brush roller can be correlated to the perforated roller, preferably in the pressure zone or at the transition point between the suction zone and the pressure zone so as to engage the material being treated.
  • at least one steam jet tube preferably in the suction zone, with the jets directed towards the perforated roller.
  • the bottom of the container may also be designed as a vibrating component or the perforated roller together with its correlated rollers may be caused to vibrate.
  • the apparatus of the present invention can be used for cleaning loose fibrous material, for example, raw wool.
  • the perforated rollers are generally only partially immersed in the treatment bath.
  • they cause a liquid flow only in the direction of material passage above a perforated intermediate bottom, whereas the liquid in the lower portion of the bath below said intermediate bottom is absolutely undisturbed, thus facilitating the settling of the dirt which has been Washed out of the wool.
  • rollers should be immersed in the treatment liquid less than about one-half, and preferably about one-third to one-fourth of their diameter.
  • the wool floating on the surface of the treatment liquid is not taken over within the vertical range of the roller but rather in the range where the roller, due to its shape, forces the wool mechanically beneath the treatment liquid.
  • This arrangement of the rollers may also be realized in an impregnating apparatus in which only a small amount of treatment liquid is required.
  • the perforated roller it is desirable to sub-divide the interior of the perforated roller not only into a suction zone and a pressure zone, but also into a pressure equalizing zone which is situated between said pressure and suction zones and which communicates with the pressure zone over the entire working width of the roller through a slit.
  • the size of the slit for the liquid passage between the pressure zone and the pressure equalizing zone can be varied and adapted to the quantity of liquid being circulated.
  • FIGURE 1 is a wet-treatment apparatus according to the present invention showing a perforated roller containing a gear pump;
  • FIGURE 2 is a wet-treatment apparatus according to the present invention comprising a perforated roller containing a cross-current pump;

  • FIGURE 6 is substantially the same as FIGURE 3 and shows in additions how the filter means swings in the liquid circulation producing a pulsating liquid flow. Also, the guide rollers in FIGURE 6 are designed as brush rollers.
  • the apparatu of the present invention comprises a liquid container 1 which is filled with a treatment liquid or liquor 2.
  • a perforated roller 4 which is partially immersed in the liquid 2 is provided as a conveying element for the textile material 3 through said liquid.
  • a roller 5 is correlated to the perforated roller 4.
  • Another roller 6 can be provided in the treatment bath. This roller squeezes the textile material 3 at the transition point between the suction zone and the pressure zone.
  • At least one brush roller 5' can be correlated to the perforated roller, preferably in the pressure zone or at the transition point between the suction zone and the pressure zone so as to engage the material being treated. After leaving the liquid, the textile material is against squeezed by means of a pair of rollers 7.
  • the liquid circulation is effected by means of two gear pumps 8 which extend over substantially the entire working width and/or drum length.
  • the suction zone and the pressure zone in the perforated roller are separated from each other by means of guiding elements 9 and 10.
  • a filter element 11 in the liquid circulation separates the solid substances detached from the textile material 3 from the treatment liquid.
  • FIGURE 2 The embodiment of the present invention according to FIGURE 2 is similar to that of FIGURE 1.
  • a cross-current pump 12 is used which also extends over substantially the entire working width and/or drum length. With large working widths several cross-current pumps 12 may be arranged side by side.
  • guiding elements 9' and 10 in the perforated roller 4 are designed as liquid displacing bodies. Between these guide elements 9 and 10' several suction sockets 13 are arranged which are distributed over substantially the entire working width. In each of these suction sockets 13 a vane-type pump 14 with a motor 15 is fastened to supports 16 of the suction socket 13. Between the suction socket 13 and the guiding elements 9 and 10" a partition (not shown) is arranged for separating the suction zone from the pressure zone.
  • perforated rollers 4 may be immersed in the liquid either completely or only partially, for example less than one-half of their diameters, depending upon the intended use of the apparatus.
  • all of the components which are arranged in the perforated roller can be combined as one assembly so that for cleaning and repair work this assembly may be removed from the perforated roller at one face as a single unit.
  • a brush roller 17 as well as steam jet tubes 18 can be provided in the treatment bath.
  • the arrows at filter 11 indicate that it can be caused to swing or vibrate so that a pulsating liquid flow can be produced. The Swinging or vibrational movement of the filter element can be more clearly seen by referring to element 11 of FIGURE 6.
  • FIGURES 3 and 4 several perforated rollers 4 are arranged in the liquid container 1. Beneath these rollers a perforated intermediate bottom 20 is arranged in order to avoid settling of the fibers. Bottom 21 of the liquid container 1 is inclined so that the sludge which settles in the container is led to a worm conveyor 22.

  • the loose textile material 3 to be treated is floated in the first zone of the bath, is drawn as a uniform fleece to the perforated roller 4 by said roller and is passed through the treatment liquid on the surface of said perforated roller.
  • the liquid drawn in at the suction zone 23 flows out of the perforated roller 4 in the pressure zone 24 and due to the inertia of the fleece, a large portion of the liquid again penetrates the fiber fleece.
  • the fibrous material is thereby opened at the same time and the separation of the dirt is facilitated.
  • the loose textile material 3 is then floated to a subsequent perforated roller 4.
  • the textile material from the last perforated roller is passed as a fleece to a pair of squeeze rollers where it is substantially dehydrated before it is subsequently passed into a wash bath (not shown).
