Definitions

  • one of the objects of this invention is to provide a novel and improved spinnerette.
  • Another object of this invention is to provide a conjugate spinnerette which is simple and easy to manufacture.
  • a further object of this invention is to provide a conjugate spinnerette wherein the amounts of each spinning solution going into the filament can be precisely controlled.
  • Still another object of this invention is to provide an apparatus wherein streams of spinning solutions flow through passageways and meet at a spinning orifice.
  • Yet another object of this invention is to provide a conjugate spinnerette wherein a threaded member is utilized to separate streams of spinning solutions flowing to spinning orifices.
  • One embodiment of the present invention contemplates a conjugate spinnerette wherein a threaded member positioned in a bore in a block is provided with recesses on the opposite sides thereof for receiving spinning solutions.
  • the spinning solutions flow through the threads, meet and flow through spinning orifices in the block to form conjugate filaments.
  • FIGURE 1 is a fragmentary perspective view of one embodiment showing the structure of the threaded insert
  • FIGURE 2 is a sectional view of the spinnerette showing the manifold connected to the threaded inserts.
  • a block 11 is shown provided with a plurality of cylindrical bores 12 and 13 which extend parallel to each other and to a face 14 of the block 11. Inserts 18 and 19 in the bores 12 and '13 are provided for separating two difierent spinning solutions and for feeding the solutions to a plurality of spinning orifices 22 extending from the bores 12 and 13 to the face 14 of the block 11.
  • the inserts 18 and 19 are formed from threaded members such as common bolts having threads 23.
  • the inserts 18 and 19 are positioned so that the crest of each thread 23 bisects the space between adjacent orifices 22, the grooves defined by the threads serving as passageways to the orifices 22.
  • each insert Opposite sides of the inserts i8 and 19 are milled away to provide recessesZd and 25 for receiving spinning solutions from manifolds 28 and 2% in the block 11.
  • the cross section of each insert is substantially T-shaped with the cross arm of the T having a semicircular configuration.
  • the threads at the end of the leg of the T are filled as indicated by reference numeral 30 so that the spinning solutions cannot flow from one of the recesses (24 and 25) to the other.
  • the manifolds 28 and 2% are connected to conventional sources 32 and 33 of spinning solution.
  • the spinning solutions are pumped from the sources 32 and 33 through the manifolds 28 and 29 into the recesses 24 and 25 in the inserts 18 and 19.
  • the two spinning solutions then flow toward each other through the thread grooves in the inserts 18 and 19, meet and pass through the spinning orifices as conjugate filaments.
  • a spinnerette comprising a body member having therein a hole and also having therein a plurality of spaced orifices extending from the hole to the surface of said body member, and a substantially T-shaped insert positioned in the hole in such a manner that the cross arm of the T covers the orifices and the leg of the T extends across the hole to divide said hole into two chambers, said cross arm having therein a plurality of spaced grooves aligned with the orifices and extending across said cross arm from one chamber to the other, said body portion having therein passageways leading to the chambers for admission of spinning solutions thereto.
  • a spinning system comprising a block having therein a plurality of spaced holes and a plurality of rows of spaced orifices extending from the holes to the surface of the block, a plurality of substantially T-shaped inserts positioned in the holes in such a manner that the cross arm portion of each T covers the orifices and the leg of the T extends across the hole in the plane of the orifices to separate the hole into two chambers, said cross arm portions having therein spaced grooves aligned with the orifices and communicating with said chambers, said block having therein a plurality of passageways leading to said chambers, and means for forcing spinning solutions through said passageways to said chambers.
