  • WERNER- NpgzLi %-%.KZMM W United States Patent M 11,050/64 U.S. Cl. 1966 Claims Int. Cl. DOlb 3/04 ABSTRACT OF THE DISCLUSURE
  • a process for the continuous treatment of a throughpassing staple fiber band with liquid which comprises the steps of forming a tubular-shaped staple fiber layer from the through-passing staple fiber band. The latter is then intensively passed through a guide zone which internally and externally supports the tubular-shaped staple fiber layer.
  • Liquid is introduced into the tubular-shaped staple fiber layer after it has left the guide zone, and the staple fiber layer is extensively freed externally and internally in a freeing zone along a predetermined length.
  • the excess liquid is permitted to flow off by free radial discharge, and then the staple fiber layer is consolidated into a compact sliver by guiding at all sides, whereafter it is subjected to a high specific surface compression which acts at all sides of the sliver.
  • the apparatus for carrying out the inventive method incorporates means which provide a guide zone for the staple fiber band and including a substantially coaxially extending liquid conduit.
  • Means are disposed after the guide zone for providing an extensive liquid discharge zone which is completely free at all sides, and following the liquid discharge zone there is provided means which define a consolidating zone for the staple fiber layer to form such into a compact sliver. Further, means are disposed at a location following the consolidating zone for providing a hydrodynamic pressure zone.
  • the present invention has reference to an improved process for the continuous treatment of a staple fiber band or sliver with liquid and also pertains to an improved apparatus for the performance of the aforesaid inventive process.
  • a further considerable object of this invention has reference to an improved process and apparatus for continuously treating a staple fiber band or sliver with liquid in order to provide effective and uniform wetting of such fiber band with such liquid, to subsequently remove the surplus liquid while reliably preventing entrainment of the thus removed liquid by the lateral regions of the fiber band.
  • the inventive process overcomes the indicated disadvantages in that there is proposed a process for the continuous treatment of a throughpa-ssing staple fiber layer arranged in substantially tubular configuration and full or intensive passing of the same through an inner and outer supporting guide zone as well as central introduc tion of liquid upon leaving the guide zone.
  • Characteristic of the inventive process is that it contemplates extensive external and internal release or freeing of the fiber layer, the flowing-off of surplus liquid by means of radial free outlets, renewed consolidation or compacting of the fiber layer into a compact fiber layer or sliver by guiding at all sides, and subsequent action of a high, hydrodynamically formed, specific surface compression or pressure which is effective at all sides.
  • This surface pressure or compression can increase to about 200 kg./cm.
  • the high specific surface compression is dependent upon the magnitude of load coming into application and the elastic characteristics or properties of the disks employed to provide such compression.
  • the inventive apparatus for the continuous treatment of a stable fiber band or sliver encompasses a guide zone having a liquid conduit coaxially penetrating through such guide zone and a subsequently arranged extensive or spacious liquid discharge zone which is completely free at all sides, as well as a consolidating zone and a hydrodynamic pressure zone.
  • the consolidating or compacting zone is preferably formed by calender roller disks and lateral closure or cover means.
  • such closure means possess a respective recess at the side facing towards the disks which merge with the converging space formed by the disks and which correspondingly narrow or converge. This recess advantageously extends to the pressure zone produced by the calender roller disks with the coaction of the lateral cover means.
  • the inventive process renders possible an extremely exact separation of the surplus liquid from the fiber band or sliver by virtue of the effective lateral sealing or closure of the pressure zone and, thus, an absolute homogeneous liquid distribution in the fiber band or sliver. Also, all air inclusions are washed away by the liquid stream extensively escaping at all sides.
  • the inventive process and apparatus structure can not only serve for the introduction of liquid into a staple fiber band but can also be used for washing out substances which are already present in solution in the fiber band or sliver, as for instance, non-fixed dyestuffs, or for floating away small loose particles, such as impurities, etc.
  • FIGURE 1 schematically illustrates the preparatory formation of a web into a fiber layer or substantially tubular cross-section
  • FIGURE 2 schematically illustrates the preparatory formation of a plurality of individual fiber bands or slivers into a fiber layer of substantially tubular crosssection
  • FIGURE 3 schematically illustrates a preferred embodiment of inventive apparatus for the continuous treatment of a staple fiber band formed according to FIG- URES 1 or 2;
  • FIGURE 4 is a cross-sectional view of the device of FIGURE 3 taken along the lines IVIV thereof;
  • FIGURE 5 illustrates a conventional pair of calender rollers
  • FIGURE 6 is a cross-sectional view of the device of FIGURE 3 taken along the lines VIVI thereof;
  • FIGURES 7 and 8 each illustrate the pressure zone between two cooperating disks and the corresponding pressure distribution
  • FIGURE 9 is a variant of the embodiment of apparatus depicted in FIGURE 3.
  • FIGURE 1 a coherent web 1 formed of staple fibers is transformed in known manner into a tubular layer 2. It is also equally possible to form such a fiber layer, here designated by reference character 2, by circularly placing against one another a number of individual staple fiber bands or slivers 3, as such has been depicted in FIGURE 2.
  • the thus formed tubular-shaped layer 2 or 2 is delivered to a guide zone A which is constructed to support the aforesaid layer at the inside and at the outside.
  • this guide zone A consists of a funnel 4 through which coaxially extends a liquid conduit 5 which piercingly extends through such funnel 4.
  • the inner diameter of the funnel 4 and the outer diameter of the conduit 5 are chosen such that there remains a throughpassage channel 5a of sufficient size for passage of the tubular-shaped fiber layer 2 or 2'.
  • the thickness of this fiber layer 2 or 2 is selected such that this channel is filled, that is, there results an intensive or full guiding at all sides of such throughpassing fiber layer.
  • the treatment liquid Upon leaving the guide zone A the treatment liquid is introduced at approximately 0.2 to 0.4 kg./cm. atmospheric excess pressure and with a surplus of such liquid. Return flow of this liquid through the funnel 4 is made impossible due to the previously mentioned full or intensive guiding of the throughpassing material by means of the cooperating funnel 4 and tube 5.
  • This tube or conduit 5 preferably extends past the guide zone A. Then, the fiber layer is extensively released or freed in a so-called freeing or releasing zone B at all sides, that is, at the inside as well as the outside. This allows the liquid introduced at excess pressure to flow unobtructedly through the fiber layer radially towards the outside.
  • the length of the free ZOne B is considerably smaller than the maximum staple length of the treated fiber material, and is preferably selected to be smaller than the mean staple length. In the free zone B the liquid is correctly embedded in the fiber layer.
  • the tubular-shaped fiber layer 2 or 2' Upon passing the free zone B the tubular-shaped fiber layer 2 or 2' arrives at a consolidating or compacting zone C formed by a funnel 6 converging or constricting to the diameter d (FIGURE 4).
  • the tubular-shaped fiber layer transforms into a compact band configuration 7, as best seen by referring to FIGURE 4.
  • the liquid which is still located internally of the tubular-shaped fiber layer is here pushed back towards the flow of material in the free zone B where it escapes radially and, therefore, the excess liquid is completely separated from the finished treated sliver.
  • the known loading device for the disk shafts has not been illustrated. Due to guiding the tubular-shaped fiber layer in two neighboring zones A and C the fibers, so to speak, form a compact filter hose through which liquid is pressed uniformly at all sides at pressure in excess of atmospheric pressure in the free zone B.
  • the sliver or fiber 7 is now guided into the pressure zone D formed by the small disks 8, 9 and the lateral closure or cover plates 10, 11 at which there is hydrodynamically built-up a very high pressure, so that there is reached an average specific compression or pressure in the order of magnitude of P equals up to approximately 200 kg./cm.
  • an average specific compression or pressure in the order of magnitude of P equals up to approximately 200 kg./cm.
  • the length L is, for example, considerably enlarged due to application of an elastic covering 12 at the disks for example a hard rubber cover, and the specific surface pressure or compression P reduced in comparison with a higher specific surface compression or pressure P generated by a smaller length L of elastic deformation.
  • the smaller length L results when using rigid disks which, for instance, are formed of steel or suitable wear-resistant plastics.
  • FIGURE 7 there appear with the same load, bands with high moisture content, and in the second case, represented in FIGURE 8, bands with less moisture content.
  • P denotes the specific pressure or compression and S the location along the sliver passing through the nip surface of the two cooperating disks.
  • FIGURE 9 there is illustrated a variant of the apparatus of FIGURE 3 for carrying out the inventive process.
  • the guide zone A, the free zone B, and the pressure zone D remain unchanged.
  • the consolidation or grouping together of the tubular-shaped fiber layer 16 shown in phantom lines is performed at both sides of the disks 17, 18 by a respective recess 19 opening towards the disks 17, 18 which is formed in the lateral cover or closure means 20, only one of which is shown in the drawing, i.e. the rear one, and which merges with the constricting or converging space 22 formed by the aforesaid disks 17, 18 and which recesses 19 likewise constrict or converge in accordance with the convergence of the aforesaid space 22.
  • treatment liquid which can be introduced into the tubular-shaped fiber band are set forth in my commonly assigned US. Patent 3,191,375, granted June 29, 1965, and entitled Process For The Manufacture Of A Twisted Yarn.
