Definitions

  • Another object of this invention is to provide a device for spinning filaments having discrete portions of a plurality of spinning compositions distributed throughout.
  • a further object of this invention is to provide a spinnerette in which two spinning compositions are combined in discrete portions and moved through a conventional spinnerette plate.
  • Still another object of this invention is to provide a spinnerette having a pair of closely spaced spinnerette plates wherein a first spinning composition is forced axially through both spinnerette plates and another composition is forced laterally into the space between the plates to flow through the downstream plate.
  • One embodiment of the present invention contemplates a spinning device wherein a pair of conventional spinnerette plates are secured in closely spaced relationship.
  • a first spinning composition is forced axially through both spinnerette plates, while a second spinning composition is forced laterally into the space between the spinnerette plates.
  • the two compositions iiow together through the downstream spinnerette plates to form filaments. Because of the high viscosity and slow fiow rate of the two compositions, these compositions do not mix to any great extent. Instead, there is a fairly clear line of demarcation between adjacent portions of the two compositions.
  • the discrete portions of the two compositions flow through the downstream spinnerette plate to form filaments which are made up of discrete portions of the compositions. Such a filament will crimp and curl when annealed.
  • FIGURE 1 is a longitudinal cross section of the device of the invention showing the construction thereof
  • FIGURES 2-6 are enlarged side views of fragments of the filaments showing typical lines of demarcation between the two compositions making up the filaments.
  • a pair of annular spacers or rings 11 and 12 are shown supporting a pair of closely spaced, conventional spinnerettes 14 and 15 on an inner manifold element 16.
  • An apertured distribution plate 2t) and the elements 11, 12, 14 and 15 are stacked on the element 16 as shown so that a first spinning composition, flowing from a source 21 through an inlet line 22 connected to the element 16, ows axially through the holes in the distribution plate and then through the spinnerette plates 14 and 15.
  • the elements 11, 12, and 14-16 are clamped and held in stacked relationship by a pair of caps 25 and 26 which are constructed and threaded together as shown.
  • the caps 25 and 26 have an internal diameter such that an annular space 30 is provided around the inner manifolds 16 and the spacer elements 11 and 12.
  • a second spining composition is fed from a source 31 through a line 32 and into the annular space 39.
  • the spacer or ring 12 is provided with a plurality of spaced apertures or ports 34 interconnectiing the annular space 30 with the space 36 between the spinnerette plates 14 and 15 so that the second composition can flow laterally into the space between the spinnerette plates.
  • the first spinning composition is forced into the inner manifold made up of the elements 11 and 16. This composition is distributed throughout the inner manifold by the distribution plate 20 and then fifows axially through both of the spinnerette plates 14 and 15.
  • the second composition is forced from the source 31 into the annular space or outer manifold 3i), from which it flows through the ports 34 laterally into the space 36 between the spinnerette plates 14 and 15.
  • the two compositions merge in the space 36 between the spinnerette plates. Because of the high viscosities and low flow rates, these compositions do not actually mix to any substantial extent. Instead, there are fairly clear lines of demarcation between the different portions of the two compositions in the space 36. Thus, when the merged compositions are forced through the downstream plate 15 to form filaments 37, these filaments will be made up of discrete portions of the two compositions. The lines of demarcation between these discrete portions, which extend across the filament at random, different angles, are of different and random configuration. The lines 40, 41, 42, 43 and 44 in FIGURES 26 are typical of the lines of demarcation separating the two compositions in the filaments. It can readily be seen that an annealing of the filaments 37 will cause these filaments to crimp and curl.
  • a device for spinning filaments comprising a housing having a first passageway therethrough, a pair of spinnerette plates mounted in spaced relationship -on the housing in such a manner that a spinning composition forced through spinning orifices in the first passageway flows axially through both of said spinnerette plates, and means surrounding the housing to form a second passageway, said housing having therein a plurality of apertures interconnecting the second passageway and the space between the spinnerette plates, said apertures being substantially equi-distant between the spinnerette plates, each of said spinnerette plates having therein an array of spinning ⁇ orifices extending substantially across and covering the face thereof so that substantially all of the face of each said spinnerette plate is provided with spinning orifices.
  • a device for spinning filaments comprising a manifold element having an aperture therethrough, a first spinnerette plate mounted on the manifold element, a spacer ring mounted fon the first spinnerette plate, a second spinnerette plate mounted on the spacer ring in such a manner that a lfirst spinning composition passed through the ⁇ aperture in the manifold element flows axially through spinning endangereds in both spinnerette plates, said spacer ring having therein a plurality of radial apertures, and a second manifold surrounding the spacer ring for directing a second spinning composition through the apertures in said ring into the spacer between the spinnerette plates, each of said spinnerette plates having therein an array of spinning yorifices extending substantially across and covering the face thereof so that substantially all of ⁇ the face of each said spinnerette plate is provided with spinning orifices.
