Definitions

  • This invention relates to a method and apparatus for treating continuously moving filamentary material of indefinite length. More particularly, the present invention relates to a method and apparatus for liquid aftertreating a warp of closely spaced parallel viscose rayon threads at a high rate of speed.
  • the filament constituting the thread after extrusion and coagulation have a very different constitution as compared with the composition of finished thread and are in a plastic condition. While in this plastic condition or so-called gel state the thread may be stretched and disturbed to a reasonable amount. However, excessive stretching or disturbing of the thread will cause an inferior product to be produced. Also, the likelihood of filament breakage increases as more tension is applied to the threads.
  • Another method is known by which aftertreatment of groups of threads at relatively high withdrawal speed may be accomplished.
  • This method comprises subjecting the threads to contact with a freely descending bath. By this process the threads are guided through liquid troughs having openings in the bottom with the threads passing vertically and downwardly through the openings.
  • the washing and after-treating effect of this method is not particularly favorable; and, in addition, it is necessary constantly to pump the treatment liquid up into the containers positioned above the baths.
  • Another object of the present invention is to provide a method of maintaining the parallel threads in a warp in close relationship to each other in order to treat a maximum number of threads of a warp of a given width.
  • a further object of the present invention is to provide a method of employing high treating speeds and yet avoiding the adverse eifects which ordinarily accompany such elevated speeds, such as liquid drag, thread tension, liquid eddies and undesirable currents, thread entanglement, and non-uniformity of physical properties.
  • a still further object is to accomplish the foregoing in a uniform and controllable manner.
  • the threads are directed through similar treating operations or to a suitable drying device after which the threads are taken up in a package form.
  • the process of the present invention is conducted in a manner wherein the threads are fully treated during a process in which the tension on the threads is held at a low constant value and the disturbance to the closely-spaced threads is held to a minimum.
  • the apparatus of the present invention briefly comprises a supporting plate which forms an acute angle with the treating bath surface.
  • two or more deflecting plates are arranged substantially at a right angle and form parallel slots between the deflecting plates and between the supporting plate and the deflecting plate adjacent thereto.
  • Two warp guiding means are arranged at the top and bottom ends of the supporting plate in such manner that the groups of threads traveling between them are in a plane parallel to the supporting plate and closely spaced from the latter.
  • a driving means is provided to propel the work between the two guiding means.
  • numeral 1 designates a positively driven roller for propelling the warp of threads 6 from a prior and similar treating operation (not shown).
  • the warp of threads 6 is guided around drum 2 which is freely rotatable and which is mounted so that it is about half emerged in the treating liquid 4 contained in trough 10.
  • a flat elongated supporting plate is mounted by suitable means and positioned at an acute angle with respect to the surface of the liquid 4.
  • An end of said plate 5 extends into the liquid and is located adjacent to the bottom of drum 2.
  • two deflecting plates represented by numeral 8.
  • the deflecting plates 8 are substantially parallel to each other and normal to the supporting plate 5.
  • the deflecting plates 8 are spaced apart and define slots between each other and between the supporting plate 5 and the deflecting plate 8 adjacent thereto. The top edges of deflecting plates 8 are slightly below the path of the thread travel.
  • Second drum 7, which is freely rotatable, is circumferentially grooved and together with drum 2 determines the path of the thread travel across the plates 5 and 8. Said drum 7 is preferably mounted within the collecting vessel 9. The grooves of drum 7 provide convenient spacing of the threads and tend to separate some of the excess liquid entrained in the warp 6.
  • the collecting vessel 9 arnasses the treating liquid which overflows over the top end of supporting plate 5 and which is separated from the threads and deflected by deflecting plates 8 into the vessel.
  • the length of plates 8 approximates the width of plate 5.
  • Roller 3 is similar to roller 1 and is used to propel the warp to a subsequent treating station or to drying devices.
  • the excess liquid which the threads pick up separates from the threads and forms a thin stream or film between the threads and supporting plate 5.
  • the angle of inclination of the plates causes the stream of treating liquid to flow down the plate 5 while the forward movement of the threads tends to urge the liquid upwardly but to a lesser degree. Any liquid flowing over the elevated end of the plate may be collected.
  • the discharge pipe of the collecting vessel 9 may provide a return directly to the container of the treating liquid as illustrated specifically herein. But it is seen that the liquid may be sent to another liquid receptacle and then recirculated for use in treating further lengths of filamentary material. Also, the liquid may be refreshed prior to each recirculation in a conventional manner. Furthermore, the collecting vessel 9 may be mounted within or without the treating liquid container.
  • the invention also provides means for applying a number of treating liquids in succession to running lengths of threads.
  • different treating liquids such as desulfurizing liquid, a bleaching solution, a solution for Washing, etc.
  • additional liquid treating stages other than those enumerated above may be used, if de sired.
  • the present invention may be used for processing filamentary material during aftertreating of other fibers, such as cuprammonium yarns.
  • Example A plurality of continuous filament viscose rayon threads spun from a plurality of spinning points and coagulated in a conventional acid setting bath were gathered into a warp having closely spaced and parallel threads.
  • the horizontal spacing of the threads was 3 mm.
  • the threads were subjected to a hot water wash treatment while using the apparatus described in the present application.
  • the stream of liquid between the threads and the plate was maintained at a depth of about 1.5 mm.
  • the linear speed of the threads during this washing operation was 156 m./min.
  • the speed of stream down the plate was measured to be about 47 m./ min. Hence, the speed of the stream was about one-third of the thread speed.
  • the threads were then completely aftertreated through other similar operations employing various conventional treating liquids and thereafter dried.
  • the physical properties showed high uniformity and the thread compared favorably with, and in some instances was better than, threads produced by the conventional bath emersion method, which, of course, had to be operated at a greatly reduced speed with the threads being further spaced apart as compared with the present invention.
  • An apparatus for a liquid treatment of a Warp of closely spaced rapidly moving threads comprising an open trough for a treating liquid, a freely rotatable drum mounted within said trough and disposed in part below the normal liquid level, a vessel mounted over said trough for collecting and returning said liquid to said trough, a flat elongated plate disposed at an acute angle with respect to the liquid level and having one end extending below the liquid level and adjacent to the submerged portion of said drums with the opposite end thereof extending over said vessel, a second freely rotatable drum mounted over said vessel, means mounted within said vessel between said second drum and said plate for deflecting liquid downwardly into said vessel and a positively driven roller for propelling a warp of threads between the two said drums and in close proximity to said plate.
  • An apparatus for a liquid treatment of a warp of closely spaced rapidly moving threads comprising an open trough for a treating liquid, a freely rotatable drum mounted within said trough and disposed in part below the normal liquid level, a vessel for collecting and returning said liquid to said trough, a flat elongated sup porting plate disposed at an acute angle with respect to the liquid level and having an .end extending below the liquid level and adjacent to the submerged portion of said drum with the opposite end thereof extending over said vessel, a second freely rotatable drum mounted over said vessel, at least two small deflecting plates arranged substantially at right angles to said supporting plate and positioned between said second drum and the end of said supporting plate, said deflecting plates defining slots for liquid to travel therethrough into said vessel and a positively driven roller for propelling a warp of threads be- 15 2,7 69,727
