  • A. HARTMANN ET AL 2,129,274 PROCESS FOR TREATING ARTIFICIAL FILAMENTS AND APEARATUS THEREFOR' 2 Sheets-Sheet 2 Filed June 14, 1934 Patented Sept. 6, 1938 PROCESS FOR TREATING ARTIFIoIAL FILA- MnN'rs AND APPARATUSTHEREFOR August Hartman and Johannes Uy'tenbogaart,
  • the invention comprises a processand apparatus for wet treatment and drying of artificial filaments or threads in the continuous process for the manufacture of artificial silk.
  • a still further object of the invention is a device for the wet treatment, and the immediately following drying, in a continuous process of filaments or threads which are led in spirals, whereby one or more rotating cylinders are provided as guiding and transporting means, these cylinders having, at least in the drying zone, full and fairly smooth outer surfaces, and whereby in the neighborhood of these surfaces a device is located which is adapted to transferring heat to those portions of the surfaces with which the filaments are not momentarily in contact.
  • Fig. 1 shows a device for wet treatment and drying of artificial filaments in side elevation in partial section
  • Fig. 2 shows a section of the device according to, Fig. 1 in the direction of the line 2-2;'
  • Fig. 3 shows a similar section of a different construction of the device
  • Fig. 4 shows the device of which Fig. 3 is a section, in side elevation.
  • Fig. 5 shows a side elevation of a further construction
  • Fig 6 is a partial section of the side elevation of a fourth construction-form.
  • the present invention is based on the use of a guiding cylinder or a group of guiding cylinders, preferably of ,cylinders with a full smooth surface, at least in so far as the drying zone is concerned. Both operations, wet treatment and drying, are achieved on one and the same cylinder or rotating device or, if desirable, one and the same group of cylinders.
  • the wet treatment in any appropriate form is carried out on a first part of the guiding cylinder or group of guiding cylinders, i. e. by means of sprinkling;
  • the thread In spirally passing over the rotating device the thread reaches the drying zone and it is an important feature of the invention that in the drying zone a highly heated'medium is applied directly to that part of the cylinder or the cylinders, with which the artificial silk windings are not, at the moment of application, in contact, or with which they do not come in contact at all.
  • the highly heated medium therefor comes directly in contact with the cylinder-walls, but as opposed to the common air-drying does not come directly in contact with the. artificial silk. t.
  • a highly temperatured heating gas of a burning device may beused as heating methe cylinder walls.
  • the highly heated medium, i. e. highly temperatured burning gas may be applied from within the guiding cylinder, as well as from the outside.
  • the cylinder or cylinders are heated from the outside it is preferable to use fireproof materials for the cylinders, which are at the same time poor heat conductors, and it-has been found that in these cases clay 'or especially porcelain pipes or rollers are very suitable, which pipes in unglazed porous form ⁇ may be easily turned, and which are highly resistant to the temperature and temperature differences,
  • two nearly parallel cylinders may be used, the axes of which however form a slight angle with one another so that the artificial silk thread, during the rotation of the cylinders is passed in 'a manner known per se in spirals over these cylinders.
  • the wet treatments are achieved, i. e. by
  • the other part of the cylinder pair. is used as a drying zone. There, the highly heated medium is applied directly to the cylinder walls, however only on such portions where the highly heated medium cannot come in direct contact with the artificial silk windings, either because the .silk windings do not pass over the portions at all, or at least do not come in contact with these portions at the moment of application of the heat. It is sufficient, that one cylinder of the pair,
  • the heating medium 1. e. burning gas, in the form of illuminating gas, water gas, generator gas, in the space between the two cylinders, near one or the other of the two cylinder surfaces with which the artificial silk does not come in contact in passing over the cylinders.
  • the heat for example, of high temperatured burning gases economically directly on the zone of the cylinder which is free of thread windings, and this heat is given up to the artificial silk windings during the continual rotation of the cylinders.
  • This heating can, e. g.,
  • Such devices may be used as are known in the technic of fiameless burning of iiluminating and power gases. be given a purposeful form, in that their effective surfaces are directed toward the rotating surface
  • Such burners can' 2,129,274 dium, which maybe brought .to play directly on Y which is to be heated and for a short space conform with the surface of the cylinder, while the rest of the burner may be prevented from giving off heat rays by a suitable insulation.
  • the single cylinders of a guiding cylinder-pair which are at an angle to one another, maybe built alike; they may have more or less a 'constant diameter and may be built along the whole length out cf the same material.
  • the heat which flows from the heated zone to the wet treatment zone may be used in heating the washing water and the like.
  • That part of the cylinder which is to be used in wet treatment processes may however also be made out of a different material than that in the-drying zone, without giving up the symmetrical form of the cylinder, or this part oi the rotating cylinder may be given a difflerent the flow of heat from the drying zone to the wet treatment zone may be hindered, and for such purposes it has been found practical to put insulating discs, insulating rings, etc., consisting for example of mica or the like, between the two.
  • the invention makes it possible to simplify the apparatus and process in the continuous method of manufacturing artificial silk in a surprising manner, and to concentrate it in a small space.
  • the thread undergoes a treatment which might be called an ironing eifect, which makes the twisting and sizing unnecessary for many uses of artificial silk, because thereby the capillary filaments are pressed together to form an integral threadshaft.
  • an ironing eifect which makes the twisting and sizing unnecessary for many uses of artificial silk, because thereby the capillary filaments are pressed together to form an integral threadshaft.
  • the device for the treatment of artificial silk is constructed of two driven treating cylinders i and 2, to which the thread is guided from a spinning device which is not shown in the drawings.
  • the thread is guided on these cylinders in spiral windings, which is achieved by the arrangement of the cylinders at an angle to one another.
  • the cylinders are cut off from the rest of the machine by a plate I I at the lower end in order to protect the machine from splashing water. Besides that, the water dripping off from the cylinder is led off by this

  • the liquid forms a thin layer around the portions of the cylinder lying below the spray tubes and fiows' can beregulated by the regulating screw 8 with a valve.
  • a surface burner is used insteadof a gas burner, it consisting of a heating plate 8 and a covering 9.
  • a gas burner it consisting of a heating plate 8 and a covering 9.
  • the surface burner may be located over the lower cylinder or in any desirable position.
  • the upper cylinder as well as the lower cylinder may be heated and the two heating devices may be connected by a connecting pipe I0, and in this case only one gas pipe is needed.
  • the liquid is led to the upper cylinder l6 as well as to the lower cylinder I], through the pipes l3, ll, l and 28.
  • a device in which only one treating cylinder I8 is provided which is sprinkled with liquid through pipes I9, 20, and which is heated at its upper front end by the heating device II.

  • Fig. 6 shows still another device, in which the heat is applied to the drying zone 23, of the cylinder 2!, from within by the heating device 24.
  • the treating-cylinder or at least its drying zone must consist, preferably, out of a substance which is a good heat conductor.
  • the thread is guided in a spiral path by the free running little guiding rollers 25.
