Definitions

  • the present invention relates to a method of treating a tow of filaments or threads in a limited space and is particularly concerned with a method of treating in non-tensioned condition a continuous tow of artificial filamentary products with a treating liquid having a specific gravity greater than the specific gravity of the tow.
  • the method of treating in a non-tensioned condition a continuous tow of filamentary products with a treating-liquid having a specific gravity greater than the specific gravity of the tow comprises introducing a tow by means of a current of said treating-liquid through a tubular structure portion ending in a portion of preferably progressively increasing width leading to a tubular structure portion substantially wider than the narrowest part of the aforementioned tubular structure, arranging that the necessary length of the upper surface of the said wider tubular structure is at a lower level than the overflow level of the treating liquid and that the speed of the treating liquid through said tubular structures and the inclination upwards in the direction of flow of the said upper surface are such that the desired quantity of tow collects against the said upper surface and that the portion of the tow withdrawn from out of the treating liquid at the exit end of the broader tubular structure has remained in the treating liquid for the desired period of time.
  • the method of thepresent invention has been found particularly advantageous for the insolubilisation of continuous travelling tows of artificial filamentary products of protein with acidified concentrated saline solutions containing formaldehyde and of the kind which are of higher specific gravity than said tow.
  • the treating liquid and the tow pass through the narrower bore of the tubular structure at relatively high speed.
  • the speed of the liquid here, which is controlled by the head or dilference in level of the liquid at the entrance to the narrower tube and the exit of the wider tube or alternatively the pumping pressure, must be at least as great as that of the tow at this point.
  • This speed of travel in the wider tube is controlled to some extent by the speed of liquid flow in the wider tube, which depends on the relative bores of the narrower and wider tubes and the initial speed of the tow; and also on the inclination of the wider tube, for the fibre, being less dense than the liquid, tends to slide up the tube.
  • the time of treatment of the fibre which is the time taken to traverse the narrower and wider tubes, depends on the above factors controlling the speed of travel, and also on the length of the wider tube, or more accurately, on the length of the column of folded fibre allowed to accumulate in the wider tube before withdrawal.
  • the tube i. e. the head
  • the bore size of the narrower tube is a matter of convenience.
  • the size of the wider tube is then determined by the required time of treatment. It is possible to vary this time within very wide limits in the same apparatus, as the fibre may be drawn through both tubes with very little accumulation in a fraction of a minute, or may be allowed to accumulate in a longer column, the length of which is determined by the length of the wider tube, so that the time of passage may take many minutes.
  • the upper surface of said wider tubular structure is inclined at an angle lying between 5 and 30 to the horizontal.
  • the tubular structure portion having the narrow bore inlet is preferably of progressively increasing width, ap
  • Example A matured caustic soda solution of groundnut globulin prepared from a solution containing 20 parts peanut globulin, 1.25 parts sodium hydroxide, 1.0 part of sodium sulphite and 77.75 parts water is extruded into the coagulating bath containing 200 gm./l. sodium sulphate and 20 gm./l. sulphuric acid.
  • the resulting tow of 15,000 filaments each of 3 to 4 denier is taken up on godets having a peripheral speed of 30 metres per minute and stretched by passing on to godets having a peripheral speed of 45 metres per minute.
  • the tow is then relaxed in a bath containing 300 gms./l. sodium chloride, 30 gms./l. sodium sulphate and not more than 3 gms./l. sulphuric acid at 20 C., removed from this bath by godets and passed into a setting bath containing 300 gms./l. sodium chloride, 30 gms./l. sodium sulphate, not more than 3 gms./l. sulphuric acid, and 5 gms./l. of formaldehyde, at 65 C.
  • the tow 1 is removed by a godet 2 of peripheral speed 26 metres per minutes and passes on to a godet 3 of peripheral speed 29 metres per minute, and then vertically downwards into the constant level feed cone 4, where it is For a tow of given size and rate of delivery, the speed of liquid in the narrower picked up by the hardening liquid which enters the feed cone through a pipe 5 and is then carried through the tube 6 and the glass cone 7 into the inclined tube 8.
  • the tube 6 is of inch diameter and the glass cone 7 is 4 inches in diameter at the open end.
  • the composition of the hardening liquid is 111 gms./l. sodium chloride, 405 gins/l. sodium sulphate, 13 gms./l.
  • the speed of the liquid flow through tube 6 is controlled by the dilference in levels of the liquid at the inlet cone 4 and the overflow at the exit end of the tube 8, which in this case is 4 inches.
  • the tube 8 is of glass, 6 inches in diameter and 6 feet long, inclined so that the exit end is raised 14 inches above the inlet end.
  • a perforated lip 9 made of lead which raises the level of the liquid in the tube 8 and allows it to how away without giving rise to local regions of high speed flow.
  • the speed of the tow at feed cone 4 is 29 metres per minute.
  • the tow forms a loose column about 4 feet long against the upper surface of the tube 8 filling roughly about three quarters of the cross sectional area and is then removed at the exit end by a godet 10.
  • the peripheral speed of this godet is adjusted to 21 metres per minute so that the time of passage through the tube 8 is constant and around 3 minutes, which is sufficient to insolubilise the protein fibre.
  • a method of treating in a non-tensioned condition without tangling a continuoustow of artificial protein filaments which comprises introducing a tow of said filaments into the upper end of a longitudinally confined downwardly inclined treating zone of relatively small cross-sectional area, propelling said tow with a current of treating and carrying liquid having a specific gravity greater than the specific gravity of said tow through said first treating zone downwardly from the upper end thereof, said liquid completely filling said zone, moving said liquid together with the tow therein out of said first treating zone and directly therefrom into the lower end of a second longitudinally confined upwardly inclined treating zone of relatively large cross-sectional area in comparison with said first zone, said liquid completely On entering the inclined tube filling said second zone, carrying said tow through said second zone by nroving said liquid in a non turbul'ent condition through said second treating zone and withdrawing said tow from the upper end of said second treating zone.
