Definitions

  • conjugate spinnerettes are complex and costly.
  • manufacture of the conventional conjugate spinnerette requires great care and preciseness.
  • one of the objects of this invention is to provide a novel and improved conjugate 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 in which the amounts of each composition going to make up the spun filaments can be precisely controlled.
  • Still another object of this invention is to provide a spinnerette capable of spinning filaments made up of more than two spinning compositions.
  • One embodiment of the present invention contemplates a spinnerette wherein an elongated T-shaped insert is positioned in an elongated, rectangular channel in such a manner that the channel is divided into two elongated chambers on opposite sides of the leg of the insert.
  • the bottom of the leg of the insert is provided with transverse grooves interconnecting the chambers and communicating with spaced spinning orifices extending through the bottom of the channel in such a manner that spinning compositions flowing from the chambers meet at and exit through the spinning orifices.
  • a third spinning composition is fed to the orifices through bores extending through the leg of the T-shaped insert so that each filament is made up of three components.
  • an elongated, T-shaped insert 11 is shown positioned in an elongated, rectangular channel 12.
  • the lower surface of the leg of the insert 11 engages the bottom of the channel and the crossarm of the insert engages the side walls of the channel 12 to divide the channel into a pair of elongated chambers 13 and 14.
  • the lower surface of the leg of the insert is provided with spaced transverse grooves 18 which interconnect the chambers 13 and 14- and communicate with spaced spinning orifices 19 in the bottom of the channel 12 and beneath the leg of the insert 11.
  • Spinning compositions are fed into the chambers 13 and 14 from sources 22 and 23 through lines 24 and 25, respectively. These spinning compositions flow through the grooves 18, meet at and exit through the orifices 19 as composite filaments 28.
  • End plates 29 and 30 are secured to the ends of the channel 12 to close the ends of the chambers 13 and 14, gaskets 33 and 34 being used to insure an adequate sealing of these chambers.
  • a third spinning composition is fed into the spinning orifices 19 through spaced bores 37 extending downward through the leg of the insert, each of the bores 37 being aligned with one of the spinning orifices 19.
  • the filaments 28 will thus be made up of three spinning solutions.
  • a groove or slot 40 along the center of the top of the crossarm of the insert 11 serves as a manifold for feeding the third spinning composition into the bores 37.
  • a cover plate 41, with a gasket 42, is secured to the top of the channel 12 to close the slot 40.
  • the third spinning composition is fed into the slot 40 through a line 44 connected to a source 45.
  • the three spinning compositions are fed from the respective sources into the chambers 13 and 14 and the slot 40.
  • the corn-positions flow through the groove 18 and the bores 37, meet at and exit through the orifices 19 as composite filaments.
  • This spinnerette is simple in construction and easy to manufacture. It can easily be disassembled for cleaning.
  • a spinnerette comprising a channel having side walls and a bottom, said bottom having therein a plurality of spaced spinning orifices, and an insert positioned in the channel and extending thereacross, said insert having a depending portion extending to the bottom of the channel to cover the spinning orifices therein, said depending portion separating the channel into a pair of compartments, said depending portion having in the lower portion thereof a plurality of transverse grooves inter-- connecting the compartments and communicating with the spinning orifices so that spinning compositions forced into the compartments flow through the grooves to the spinning orifices, said insert having in the upper portion thereof an opening defining a third compartment for receiving a spinning composition, said insert also having therein a plurality of bores interconnecting the third compartment and said transverse grooves.
  • a spinnerette comprising an elongated channel having side Walls and a bottom, said bottom having therein a plurality of spaced spinning orifices extending therethrough, an elongated T-shaped insert positioned in the channel with the lower surface of the leg of the insert in engagement with the bottom of the channel and with the crossarm of the insert in engagement with the side walls of the channel in such a manner that the channel and the insert define a pair of elongated chambers on opposite sides of said leg, a pair of end plates secured to the ends of the channel for closing said chambers, said leg having in the lower surface thereof a plurality of transverse grooves interconnecting the chambers and communicating with the spinning orifices, said T-shaped insert having in the upper surface thereof an elongated slot lying in the plane of said leg, said insert also having a plurality of spaced bores interconnecting the slot and the transverse grooves, and a cover plate secured to the channel to cover the slot in the insert.
