Definitions

  • the desired result is better achieved with broad-jet nozzles with an elliptical surface, in which the short axis of the ellipse is as small as possible in relation to the long axis.
  • the ellipse also makes it possible to arrange a large number of nozzle openings largely next to one another. Because of their lengthened form, nozzles of this sort require a special spinning head consisting of a flange and counter-flange with holding screws.
  • the filament drawing-off devices must be adapted to conduct the wide-band-type rope so that a vertical drawing-off of the filaments from the surface of the nozzle is assured.
  • the spinning openings arising from the diagonal drilling of the inclined nozzle surface at an angle differing materially from 90 bring about an asymmetrical viscose filament formation because, for a given filament cross section, the viscose emerging at the higher-situated part of each nozzle opening contacts the sulfuric acid spinning bath rising from underneath later than the viscose emerging at the lower-situated part of the opening.
  • the structural differences in the fibers caused by this asymmetrical thread formation bring about a spiral crimping, similar to that of wool.
  • the acute angle 'be'tween the surface through which the hole is drilled and the axis of the hole does not exceed 45
  • the spinning nozzle according to the invention is especially advantageous because the fresh spinning bath rising from underneath in the hollow body of the nozzle necessarily reaches all the nozzle holes before it runs off over the upper edge of the nozzle. The nozzle thus becomes, as it were, itself a spinning trough, in whichas in spinning in a tube-the thread formation takes place in an evenly flowing spinning bath.
  • the invention consists of a ring-shaped nozzle, the
  • a preferred embodiment of the invention is illustrated in the drawing wherein a diametric cross section of a ring-shaped nozzle is illustrated.
  • the nozzle comprises a conical wall 10 tapering inwardly to a central opening 12 formed by an inwardly flanged cylindrical wall 14 with flange ring defining an opening 16.
  • the nozzle has a flanged, cylindrical outer wall 18, which, together with the conical wall 10 and cylindrical wall 14, defines an annular space 20.
  • the conical wall 10 is provided being joined with an outer peripheral wall and defining therebetween a hollow, peripheral space, the inner wall having a portion tapering inwardly toward the middle of the nozzle with a plurality of apertures parallel with the jet axis in said tapering portion communicating with said space and disposed with the axes thereof at an acute angle not greater than about 45 with respect to the surface of said tapering portion.
  • a spinning jet with a central opening therethrough defined by an inner circular peripheral wall, said inner wall being joined with an outer circular peripheral wall and defining therebetween a hollow, annular space, the inner wall having a portion tapering inwardly toward the middle of the nozzle with a plurality of apertures parallel with the jet axis in said tapering portion communicating with said space and disposed at an acute angle not greater than about 45 with respect to the surface of said tapering portion.
  • a viscose spinning jet with a central opening therethrough defined by an inner peripheral wall, said inner wall being joined with an outer peripheral wall and defining therebetween a hollow, annular space, the inner wall having a portion tapering inwardly toward the middle of the nozzle with a plurality of apertures parallel with the jet axis in said tapering portion communicating with said space, each disposed at an acute angle differing materially from with respect to the surface of said I v tapering portion suflicient to provide spirally criinped,
  • a ring-shaped spinning jet with a central opening therethrough defined by an inner peripheral wall, said inner wall being joined with an outer peripheral wall and defining therebetween an annular space and including an inner wall conically tapering toward the opening of said nozzle; and a plurality of apertures parallel with the jet axis in said conical wall communicating with said space and disposed at an acute angle not greater than about 45 with respect to the surface of said'conical wall.
