Definitions

  • U-S. 5 comprises a container means adapted to contain 3 68/184 treatment liquor and composed of a conveying zone [51] Int.
  • the present invention relates to an apparatus for the treatment of endless material lengths or material lengths, the ends of which are joined.
  • the endless material lengths are treated with dyestuffs, solvents, washing liquors or the like.
  • the apparatus consists of a container adapted to hold the processing medium and the material to be treated including a conveying element.
  • the container comprises a dwelling and a conveymg zone.
  • This type of processing device e.g., the winch beck has lately been regaining importance for discontinuous treatment processes, especially for dyeing processes and the like, wherein the material is subjected to high pressure and high-temperature conditions.
  • the dyestuffs are set on the textile materials-under hightemperature conditions.
  • the temperature used depends on the temperature resistance of the dyestuffs and the material to be dyed. The higher the temperature, the shorter the dyeing or heat-setting period. High temperatures also provide a better swell reaction of the fibers and more rapid penetration and levelling of the dyestuffs. That is why machines have been constructed in which the textile materials can be treated not only under atmospheric pressure but also under high pressure.
  • the high-temperature winch beck is an example of such a machine.
  • It consists of an autoclave which is filled half-way up with dyeing liquor and in which there is disposed a winch and possibly also a guide roller arranged above the liquor level for the material to be conveyed.
  • the ends of the material to be dyed are joined so that an endless rope is produced and the material is then made to dwell in the liquor, possibly after having been slightly plaited.
  • the material is introduced and removed from the liquor by the winch.
  • the conveying element of which are a kind of Venturi tube which operates on the same principle as the water-jet pump.
  • the textile material rope or endless material length is fed into the tube and dragged or pushed through the tube together with the dye liquor which is pressure-injected.
  • There is no lengthwise tension exerted on the material because the textile material floats in the liquor and does not come into contact with the walls of the tube and especially because the liquor is forced to penetrate the material in the diffuser portion of the tube.
  • this conveying system is disadvantageous in that its use is restricted to material ropes, to material tubes with a small diameter or to flat materials which can be transformed into a thin long roll.
  • the above-mentioned disadvantages may be eliminated and a much improved apparatus for treating textile materials may be obtained by designing the conveying element as a rotating perforated drum which is subject to a suction draft.
  • the main advantages of a perforated drum which is subject to a suction draft are well known.
  • the material to be treated adheres tightly to the drum jacket, is penetrated by the treatment medium and can be conveyed by the drum at any required speed.
  • the material to be treated can be fed to the perforated drum in several ways. It can be advantageous, for instance, if the liquor level extends up to the point where the textile material is transferred from the processing liquor onto the perforated drum or up to the point where the material is released from the drum and again immersed into the liquor in order to be conveyed through a dwelling zone. It is thus possible to let the textile material float to the perforated drum by which it is then taken up, out of the liquor and conveyed without any tension.
  • the perforated drum in such a way that it is entirely immersed in the liquor so that not only the processing medium which has previously been taken up by the material, but any volume of liquor for example, dyestuffs is drawn through the material. This results in a very uniform and intensive application of the dye particles.
  • the section of the drum that is not covered by the textile material is preferably screened off from the suction draft by a baffle plate disposed on the inside of the drum jacket.
  • the apparatus can be operated both with atmospheric pressure and under high-temperature conditions.
  • the processing liquor container can, similarly as in a hightemperature winch beck, be closed airtight and the processing medium heated up above its boiling point under atmospheric pressure by means of heating aggregates.
  • the cross section of such a container in which the material is treated under excess pressure, can be keyhole shaped.
  • the perforated drum is then arranged in the upper, wide part whereas the lower, narrow part serves as the dwelling zone.
  • the dwelling zone can be designed as a double channel, i.e., the tube can be subdivided by a partition wall.
  • the holding capacity of an apparatus which is operated under high-temperature conditions and is used for dyeing textile materials, for example, should be very great so that a maximum quantity of material can be treated in a very short time.
  • the conveying speed of a perforated drum can be very high, e.g., up to 200 m/min. Apart from safeguarding the uniform dye penetration with any color shade, the high conveying speeds also ensure shortest possible treatment periods.
  • FIG. 2 is a section through the apparatus according to FIG. 1 along the line Il-II;
  • FIG. 3 is a section of an apparatus similar to that shown in FIG. 1, except that the liquor level is beneath the perforated drum.
  • the apparatus for the treatment of endless textile material lengths comprises a housing 1, the width and length of which depend on the width and length of the material being treated as can be gathered from FIG. 2.
  • FIG. 1 shows that the cross section of the apparatus is roughly key-hole shaped.
  • a perforated drum 2 is arranged in the upper, essentially circular part of the apparatus.
  • the jacket section of this perforated drum which is not covered by the textile material being treated is screened off from the suction draft which is produced by an axial pump 3 by means of a bafile plate 4 which is disposed at the inside of the drum jacket.
  • the perforated drum 2 is as wide as the housing 1 and is supported in the front walls of the housing 1 (see FIG. 2).
  • the impeller 4' of the axial pump 3 which is driven by the motor 5 which in its turn is arranged outside the housing 1, axially penetratesone front wall of the perforated drum 2.
  • the axial pump 3 serves for drawing the liquor in the drum in the direction of the arrows 6 and for conveying it via the pump compartment 7 into an annular channel 8 which encircles the perforated drum and from where the liquor is again drawn towards the perforated drum, through the perforated plate 9.
  • the housing 1 has a filling-hole 10 which can be shut'airtight by means of a lid 11.
  • the hermetic closure of the housing 1 by the lid 1 l is absolutely necessary if the device is to be operated under high-temperature conditions.
  • High-temperature conditions are achieved by heating the processing liquor which is contained in the housing with a level 12 which stands above the perforated drum, by means of heating elements 13 which are arranged in the annular channel 8. The liquor is heated, at normal pressure, beyond its boiling point and there is an excess pressure produced in the housing.
  • the high-temperature process can begin after the lid 11 has been shut.
  • the residual air in the housing is exhausted through the valve 15, the processing liquor is heated up to the required temperature and the perforated drum 2 is made to rotate by the motor 16.
  • textile material adheres to the jacket of the perforated drum 2 by the suction draft which prevails at the drum surface and is transported by the perforated drum 2 at the rotating speed of the latter.
  • the textile material is thus guided from one part of the channel 17 of the dwelling zone to the other part of said channel and before being introduced onto the perforated drum it can advantageously be guided over two expander rollers 18 which ensure the absolutely plait-free feeding of the material onto the drum surface.
  • this apparatus can be used for the dyeing or all kinds of high-temperatureprocessing of any type of textile material, e.g. materials in rope form, woven or knitted materails, tubular knit materials and even tufted materials. All of these materials feature a very full handle after having been processed and, depending on the dyeing time and dyestuff concentration, they will also have the required final color shade.
  • FIG. 3 shows a device which is similar to that shown in FIG. 1, the difference being that the liquor level 20 is not above but beneath the perforated drum 2'or at the points where the textile material is transferred from the liquor onto the perforated drum or released from the drum and returned to the processing liquor.
  • the perforated drum is surrounded by air.
  • the upper part of the housing can be shut airtight by means of a lid. Since in this case the textile material which is to be conveyed by the perforated drum adheres to the drum surface by the suction draft of air, a radial fan is utilized instead of an axial pump 3.
  • the textile material is transferred from the processing liquor to the perforated drum 2 by driven guide rollers 21 so that it is ensured that even materials which do not float in the liquor can be conveyed by the perforated drum without being subjected to any lengthwise tension.
  • elements 22 At the delivery side of the perforated drums of both devices shown in FIGS. 1 and 3, there are provided elements 22 which ensure the automatic plaiting of the material which then passes the dwelling zone in plaited form.
  • An apparatus for the treatment of endless textile material lengths which comprises a closed container means adapted to contain a treatment liquor and having a conveying zone and a dwell zone, partition means dividing said dwell zone into two channels each in communication with each other and in communication with said conveying zone, sieve drum means subjected to a suction draft rotatably disposed in the conveying zone, said sieve drum means and said channels being arranged so that said textile material is conveyed in a continuous manner from said sieve drum means into one of said channels around said partition means and through said other channel to said sieve drum means, plait means disposed in said one channel immediately adjacent to said sieve drum means for introducing said textile material into the one channel of said dwell zone, said plait means moving said material to and fro thereby plaiting said material whereby said material is conveyed in a tension-free state through said channels and guide means disposed in said other channel immediately preceeding said sieve drum means for effecting plait-free feeding of said textile material onto said sieve drum means.
  • treatment liquor fills the dwell zone and establishes a level into the conveying zone up to the point where the textile material is transferred from the treatment liquor to the sieve drum means or the point where the textile materi-' a1 is removed from the sieve conveying means and reintroduced into the treatment liquor for conveyance through the dwelling zone.
  • heating means are disposed in the dwell zone of the container below the level of the treatment liquor.
  • heating means are disposed in the conveying zone of the container near the surface of the sieve drum means.
  • partition means extends from a point close to the bottom surface of the sieve drum to the lower portion of the dwell zone, said partition means terminating at a point sufiiciently above the bottom of the dwell zone to enable the conveyance of the textile material from one channel to the other.
  • said guide means comprises a plurality of driven guide rollers disposed immediately subjacent to said sieve drum means.
