Definitions

  • This invention relates to the production of high tenacity yarn and more particularly to an improvement in apparatus for spinninghigh tenacity viscose yarn whereby filament breakage is reduced and higher spinning speeds are achieved.
  • shields In an attempt to prevent yarn damage during high tenacity spinning, shields have been associated with the spinnerets in a manner to protect the delicate freshly formed filaments until their regeneration is complete enough so that their mechanical strength is adequate to resist ordinary stretch and aftertreatment without damage.
  • the shields of the prior art are of two general types, those supported from the spinneret and those separately supported.
  • One known type of separately supported shield is a glass tube located in accurately spaced registry with the spinneret. This construction has the disadvantage of being very hard to thread in and very hard to adjust as to the axial and radial registry of the spinneret with the tube.
  • Figure l is a schematic view partially in elevation and partly in transverse section showing a typical installation of a spinning unit in a spin bath, the spinneret assembly being provided with the improvement of the present invention
  • Figure 2 is a view in vertical section of the spinneret assembly of the present invention showing the position of the filaments during spinning;
  • Figure 3 is a view in cross section taken on line 33 of Figure 2;
  • Figure 4 is a view also in cross section taken on the line 44 of Figure 2.
  • the numeral represents a spin bath container having therein a spin bath of known spinning difficulties.
  • the spinneret assembly is generally designated by :11 and viscose solution is supplied to it through a tube 12 from a pump 13.
  • the pump 13 and the tube 12 are shown only schematically, it being customary to provide in the line a candle filter and some arrangement for pivoting the whole assembly about a point outside of the bath, so that an individual spinneret assembly can be removed from the bath and to discharge to waste in the event of local It is intended that these conventional arrangements be present when the invention is used but, since they form no part of the invention, they have not been illustrated.
  • the viscose supply tube 12 terminates in a flared mouth or flange 14. It supports the spinneret through a threaded sleeve 15 which bears upon the flange '14 through an intermediate rubber washer 16. Axially beyond the mouth of the tube there is a heavy, rubber washer 117 of an nular form which supports a filter fabric '18 in spaced relation to the face of the spinneret 19. The spinneret 19 is held by another sleeve 20 in threaded engagement with the sleeve 1-5, all as can be seen by reference to Figure 2.
  • the spinneret is assembled and disassembled by screwing the inner and outer sleeves 1'5 and 20, respectively in relation to one another and that these parts are suspended in the bath from the tube 12.
  • the internally threaded sleeve 20 is provided with four external protuberances 21, the spacing and shape of which is most readily apparent in Figure 3. These protuberances can be used as grips for rotating the sleeve 20 to assemble or disassemble the spinneret assembly as is necessary, for example, in the replacement of the filter.
  • the protuberances perform another function in the location of the hollow, tubular, soft rubber shield 22 which constitutes the improvement of the present invention.
  • This shield is provided near one end with four spaced, round apertures 23 of a size, shape and location -to receive therethrough the protuberances 21 thereby to position the shield as shown in Figure 2.
  • one end of the shield fits over the outer surface of the sleeve 20 and the protuberances 21 project through apertures in the sleeve.
  • the protuberances orient the sleeve on the spinneret both axially and circumferentially. Since the sleeve is circumferentially symmetrical, it is the axis orientation that is important for, in addition to the holes at '23, the sleeve has six elongated slots 24 through which the spin bath liquid obtains access to the freshly spun yarn issuing from the spinneret.
  • these slots 24 are symmetrically, circumferentially spaced and extend axially of the sleeve for less than one-half or, as shown, about onequarter of its length beyond the face of the spinneret. It is also to be noted that these slots begin substantially in the same plane as the face of the spinneret.
  • the sleeve 22 is conveniently made of soft rubber, either natural or synthetic, which permits this member to be readily attached to or removed from the spinneret assembly in the confined spaces occupied by the bath.
  • the resilient material of which the sleeve 22 is constructed must be resistant to the action of the hot dilute sulphuric acid usually used in the spin baths. Temperatures of 70 C. or more are conventional.
  • One satisfactory sleeve has been made of soft gum rubber 7% inches long, 1 /2 inches inside diameter with a As inch wall thickness. Of the 7% inches of length an inch overlies the sleeve 29.
  • the slots 24 are slightly over 1%.

  • An assembly for spinning viscose yarn comprising a spinneret, a sleeve for securing said spinneret in spining position, an elongated tubular shield formed from resilient, self-supporting material having one end adapted to be supported by said sleeve in operative position, coperating means on said sleeve and said one end of said shield for attaching the shield to the sleeve, and means defining a plurality of symmetrically arranged, circumferentially spaced and longitudinally extending slots in said shield, said slots in said operative position beginning substantially at the plane of the face of said spinneret and extending away from the spinneret face about onequarter the length of said shield.
  • An assembly for spinning viscose yarn comprising a spinneret, a sleeve for securing said spinneret in spinning position, said sleeve having a plurality of circumferentially spaced protuberances extending therefrom, an elongated tubular shield formed from resilient, self-supporting material having one end adapted to be supported by said sleeve in operative position, means defining a plurality of circumferentially spaced apertures in said shield near one end thereof, said apertures in said operative position being adapted to receive said protuberances, and means defining a plurality of symmetrically arranged, circumferentially spaced and longitudinally extending slots in said shield adjacent to said apertures, said slots in said operative position beginning substantially at the plane of the face of said spinneret and extending away from the spinneret face about one-quarter the length of said shield.
