  • the present invention proposes a method according to which the dyeing is performed from inside the reeled yarn completely devoid of support by an expansion apparatus, essentially comprising a resilient deformable expansion chamber of a radial arrangement or configuration, internally having, between two ad joining arms, independent channels, through which the dye is injected in the yarn, a tight-seal between the several compartments being assured through the pressure exerted by the deformable chamber directly against the inner walls of the yarn winding, this pressure being the same as or higher than the dye injection pressure.
  • FIGS. 1 and 2 are sectional views according to line I'-I of FIG. 3 prior to and after expansion, respectively;
  • FIG. 3 is a longitudinal sectional view showing the apparatus according to the invention.
  • the apparatus substantially comprises two plates 1 and 2, respectively, which are interconnected by posts 3, so as to form a supporting base, these plates being fixedly connected to a preferably metal, central tube 4 which at its end opposite the base is closed by a throttle valve, designated as a whole at 5, an inlet 6 being provided at the other end thereof for air feeding or other pressure fluid.
  • a throttle valve designated as a whole at 5
  • an inlet 6 being provided at the other end thereof for air feeding or other pressure fluid.
  • a deformable resilient chamber is provided and secured to the opposite ends of the tube by clamping clips 8 and 9, ensuring the sealing thereof relative to the outer surface of tube 4.
  • Said deformable resilient chamber designated as a whole at 10, is in the example shown in the drawings shaped with several radial bendings, so as to cause the same to take a star-like arrangement with radially arranged walls 11.-l2, 1l'l2, etc., respectively enclosing therebetween spaces l3, 13, etc.
  • pipes 14 are provided and substantially parallel with the central tube 4, thus having a cylindrical sector attitude coaxial with said tube 4.
  • These pipes are closed at their outer end and provided with a set of holes 15 arranged along one or more generatrices outwardly facing of each pipe, the other end of each pipe being connected at 16 to the inside of the support comprising said plates 1 and 2 with feed conduits for pressure dyes.
  • the operation of the apparatus according to the invention is substantially as follows:
  • the yarn, as reeled in an ordinary way, is unthreaded from the support on which the winding was provided and, without any replacement of the support, is threaded onto the assembly of pipes 14 maintained at the clamped position, as shown in FIG. 1, by the resilient clips 18 and 19; whereupon, pressure air or fluid is supplied through inlet 6 to tube 4, thus causing the resilient expansion chamber 10 to bulge and bring its outer portions 10' to contact the inner surface of the yarn winding, thereby exerting a suitable pressure thereon and dividing the inner zones of the winding into as many tight-sealed compartments as the loops of the expansion chamber, or the pipes 14 which are also urged by the expansion chamber against the inner surface of the winding.
  • the pressure dyes are supplied through the inlets 16 into the several pipes 14. Therefore, these dyes will reach the yarn winding from the inside through the holes 15 as pressed against the inner surface of the winding.
  • the duration of which will be adjustable at will in accordance with requirements, the dye supply is cut off and the circuit is opened for depressurizing the expansion chamber.
  • the resilient clips 18 and 19 bring the pipe and expansion chamber assembly back to its original position as shown in FIG. 1, thus making it possible to unthread the yarn winding from the apparatus (or vice versa) in order to accomplish then the subsequent washing operations and the like by usual techniques.
  • the essential advantage of the method and apparatus according to the invention is that the dyeing can be accomplished to provide chromatically discrete flamings from inside the yarn winding without any need of winding up the yarn on particular supports or large spindles, thus obtaining the division into as many tight-sealed compartments as the various desired zones to be involved by a single dye with a truly tight-sealing between one and another compartment, this sealing being substantially adjustable at will and assured by a pressure which may be higher than or the same as that required for dye injection.
  • the expansion chamber could have particular star-like or radial configurations also at a rest condition, so that peripheral zones would be already provided for adhering to the inner surface of the reeled yarn and zones for accomodating the various pipes for dye injection, whilst, as a limit, this chamber could be simply a tubular chamber allowing for the final required deformation by expansion to be caused by the resistant forces (inner surface of the reeled yarn in the interspace between two pipes and said pipes).
  • the expansion chamber may be made of natural or synthetic rubber of the type capable of withstanding the temperatures involved.
  • a method for reeled yarn dyeing as carried out by operating from inside the yarn winding completely devoid of support, having expansion means capable upon expansion of providing individual tight-sealed compartments, within which dye injectors are accomodated.
  • An apparatus as claimed in claim 3, comprising resilient clips or similar means for inwardly assembling said tubes or pipes and said expansion chamber when pressure fluid is cut off.
