Definitions

  • the invention relates to a method of dyeing or impregnating textiles and to an apparatus for carrying out the method of the invention.
  • the object of the invention is to devise a method of the aforesaid kind in which blurred colours are avoided, simultaneously with obtaining an economy in the consumption of liquid, the object being more particularly to render dyeing of multicoloured yarn possible in such manner that it is easy to provide a succession of densely located colour zones in the yarn which alternate in any desired manner in succession, so that the colours will not be located in zones within which the diiferent colours are always succeeding each other in a specific sequence.
  • This has, in fact, the drawback that woven or knitted textiles made of such yarns with regularly changing sequence of colours will be inclined to produce a pattern (for example a pattern of arrowheads) that cannot be predicted and therefore is irreproducible.
  • This phenomenon is due to the fact that sections of uniform colour in the consecutive threads of the weaving or knitting will sooner or later coincide along certain lengths. If, however, yarn is used which is dyed in zones in which the succession of the individual colours is continually changing, it is possible to obtain a product with a ecked appearance and a homogeneous mixture of the colours used without forming a more or less casual pattern, that is, the product becomed reproducible.
  • An essential feature of the method according to the invention is that the textile material is placed in a container having partly movable walls consisting, for example of elastically deformable material compressing the textile material. This is accomplished for example by the establishment of a pressure diierence between the inner and the outer surface of the container with simultaneous or subsequent intake by suction of impregnating or dyestui liquid flowing into the textile material from supply pipes.
  • the supply pipes are separately connected with one or more containers with dyestuif liquid, the compression being subsequently relieved simultaneously with an elastic expansion of the textile material.
  • the elastic expansion of the material and the slight amount of liquid that can be .absorbed in proportion to the weight of the material in this manner ensure that blurred colours after completion of the impregnation are avoided and that the consumption of liquid will be very small.
  • the object of the invention is also to manufacture a simple and effective apparatus for carrying the method into effect.
  • the apparatus consists of few parts and is easy and cheap to manufacture, and owing to the regular design of the outer wall of the cylinder it is possible to obtain a quick and uniform supply of liquid to the different sections of the yarn so that the colours do not become blurred, but meet at sharply defined boundaries.
  • the method requires no more than a minimum of liquid so that an economy of dyeing liquid is obtained.
  • the process may be controlled from outside, and as the dyestuff containers are readily exchangeable or the pipes connecting the dyestutf containers and the liquid channels may be used to connect different dyestuff containers with different pipes, the succession of the colours may readily be varied perfectly freely.
  • FIG. 1 shows diagrammatically an axial section through an embodiment of the apparatus according to the invention
  • FIG. 2 is a section taken on the line II-II of FIG. l.
  • the apparatus illustrated has a cylinder 1 forming a casing with an outer wall 2 which is closed above by a cover 3 and below by a welded end plate 4 which at the circumference constitutes a flange projecting from the cylinder.
  • a cylinder 1 forming a casing with an outer wall 2 which is closed above by a cover 3 and below by a welded end plate 4 which at the circumference constitutes a flange projecting from the cylinder.
  • In the outer side of the wall 2 are at regular intervals formed grooves which open outwards and constitute liquid channels extending along generatrices from the ange at the end plate 4 and upwards through the major part of the height of the cylinder.
  • the cylinder wall 2 has a throughgoing hole 6.
  • the textile material for example skeins 9 of yarn to be dyed, is placed one skein on top of the other around the cylinder 1.
  • a exible cover in the form of an air-tight transparent plastic bag is pulled down over the cylinder 1 so as to cover the skeins 9, and the edge of the bag mouth is connected tightly with the projecting flange of the end plate 4; the said flange acts as supporting edge for the lowermost skein.
  • Each of the channels communicates through a hole 7 provided in the bottom 4 with a container 11 for dyestuff liquid, the said container having a connecting pipe 12 or another pipe which is immersed in a container with the dyestuff liquid which is to be passed up through the pipe for dyeing the skeins opposite same.
  • the interior of the container 1 may through an opening 13- be put into communication with a vacuum source (not shown) and through an opening 14 be put into communication with the atmosphere.
  • the dyeing of multi-colored yarn takes place after the individual channels 5 have been connected with a dyestuff container so that the supply of dyesturf to the channels alternates in the predetermined succession along the circumference of the cylinder.
  • a vacuum is produced in the cylinder 1 by evacuation through the opening 13, and owing to the holes ⁇ 6 and the grooves 5 the plastic bag forming the cover 10 is pressed towards the skeins 9 so that these are compressed and caused to rest tightly and regularly around the cylinder 1 and the channels 5.
  • the vacuum in the cylinder is destroyed by the vacuum source being cut olf and the passage 14 being opened to atmospheric air, by which excessive dyestuf liquid in the channels returns to the respective dyestui containers and the compressed textile material may again expand freely. This will ensure that the material after the process being lfinished contains no more dyestuif liquid than required so that the colours will not blur each other.
  • the apparatus may easily be cleaned by passing the connecting pipes 12 to a container with cleaning liquid instead of to the dyestuff containers.
  • a method of forming and/or impregnating textile material characterised in that the textile material is placed in a container having partly movable walls consisting, for example of elastically deformable material compressing the textile material, for example by the establishment of a pressure difference between the inner and the outer surface of the container with simultaneous or subsequent intake by suction of impregnating or dyestui liquid owing into the textile material from supply pipes, each of which are separately connected with one or more containers with dyestuif liquid, the compression being subsequently relieved simultaneously with an elastic expansion of the textile material.
  • An apparatus for dyeing or impregnating circularly arranged textile material characterised in that it has a cylinder with a circumferential length substantially equal to the circumferential length of the textile material, such as skeins to be dyed, and with a number of regularly distributed, longitudinal grooves which form liquid channels in the outer wall of the cylinder and are adapted to be connected with a vacuum source, the said channels being each connected with a dyestuif container, and the apparatus having an outer cover of flexible material and of such form that it is capable of enclosing the cylinder and the textile material, for example skeins, arranged on same and to form a sealed closure around the said skeins.
