Definitions

  • the spinning vessel 1 is flared or bell-bottomed so as to cause the change of direction of the current I I and that the actual quantity of liquor is progressively greater as the coagulation is completed, so the induced downward current gets stronger and more turbulent by the mere friction of the now solid fibres passing through the liquor. Therefore, the maximum rate of flow is at the bottom end of the funnel so that this quantity must be replaced by the upward current, which of necessity must also be atits maximum at the bottom of the funnel.
  • the flared or bell-bottomed spinning vessel is tapered upwardly as shown so as to ensure that the slow dispersing action of'the entering liquor is distributed throughout the length of the spinning vessel 1, i. e. a very steady upward current of replenishing liquor is ensured.
  • the modification of the bell-bottomed funnel shown at Figure 2 is what we term the crinoline or reversal type. This is specially applicable to two liquor spinning where a certain amount of turbulence is created at the position where the two liquors meet owing to the sudden reversal of the upward flowing liquor of a higher specific gravity.
  • the form of funnel is such that the upward flow is arrested and the direction change is made more gentle by the lip 2 formed between the truncated cone. 3,.and the cylindrical ortions of the funnel as shown.
  • t e cone shaped upper portion'3" facilitates creation of a slight ejectora'etion on the downward current of. the exhausted. weaker liquor out of the'drawing out zone,
  • thelower portion the spinningyessel is so shaped as .to still of said vessel being slightly tapered upward from its lower end andhaving a longitudinally curved portion adjacent said wider, lower, end.
  • a spinning vessel for use in the manu facture of artificial silk thread by the stretch further increase the cross-sectional area for 1 the dispersalof thestrong currents or eddies.
  • the length of thecoagulat-ion field afiorded by. the spinning vessel is of the utmost'importance, and, in practice, itis found to. be preferableto employ long spinning vessels
  • the vparticular shape. illustrated ensures a I for the. manuf t of threadshof coarse counts-Land short spinning vessels for finer counts.
  • spinning vessels of simple construction and which have great advantages over the older types 'of-spinning vesselshaving inner. inverted conicalfunnels, and further that the. spinning vessels according to the invention offer no obstructions or restrictions to the downward passage. ofthe thread andare therefore easyito startup.
  • Aspinning vessel for use inthemanu- It will be seen that the present invention factureof artificial silk thread by thestretch spinning process, in which the circulation of coagulating-liquid is induced by frictional contactbetween such liquid and the filaments passing 'therethrough, said vessel being of vertically elongated form, having. a height several times greater than its maximum transverse diameter, and ofgreater width at its lower, liquid .inlet, endthan at .its upper v en'd,:so that an increased area is provided for dispersion of eddies of liquid in the neighborhood of points Where the v:trictional contact between the filaments and. liquid is at its maximum; v .7
