Definitions

  • the strands are hung with play on the upper and lower thread bars of a strand thread carrier.
  • the skeins of thread are dewatered, usually in a centrifuge. To do this, they are removed from the support arms of the strand yarn carrier and inserted into the centrifuge.
  • the actual drying process takes place after dewatering.
  • the skeins of thread are hung up again on supporting rods.
  • the support rods are suspended in the transport devices of a suitable dryer.
  • a duct dryer is particularly suitable, in which the goods cannot be over-dried due to the relatively low working temperatures and largely cools down and leaves the machine with a good grip.
  • the present invention is based on the object of specifying a method of the type mentioned at the outset which considerably accelerates and reduces the cost of treating yarn in strand form.
  • the distance between the upper and lower support rods is preferably reduced so far in the centrifuge that all yarn strands can lie against the wall surrounding the strand yarn carrier.
  • a suitable device in particular with a suitable strand yarn carrier.
  • a suitable strand yarn carrier with a central dome to which at least three radial holding arms are attached in at least two planes and between the holding arms of each plane a number of supporting rods lying concentrically to one another, is characterized in that the fastening takes place via a closure which resists the centrifugal forces, and that a device is provided that allow the simple and quick reduction and enlargement of the distance between the levels of support rods.
  • a one-sided, swiveling mounting of the holding arms makes loading and unloading the strand yarn carrier easier. It also improves strength and stability against centrifugal forces.
  • a preferred further development in the form of a jacket placed around the strand yarn carrier, which is preferably divided into segments that can be pivoted with the support arms, enables optimal liquor guidance and thus uniform coloring, best support of the Yarn strands during centrifugation and optimal dry air flow.
  • the jacket does not hinder loading and unloading.
  • the strand yarn carrier has a bottom on its underside, which guides, deflects and evens out the flowing media - liquor, dry air.
  • This intermediate floor is therefore an inseparable part of the strand yarn carrier. It enables the process conditions to remain constant in a wide variety of treatment boilers.
  • the base has at least two perforated base plates, wherein - based on the flow of the yarn strands from bottom to top - the base plates lying higher up are perforated more finely than the ones lying further down.
  • the bottom plate is preferably conical to spherical and covers the inflow opening in the intermediate floor. This results in an excellent homogenization of the flows despite the necessary deflection, so that optimal and identical process results are achieved both during dyeing and during drying over the entire cross section.
  • the top floor plate which has the finest perforation, is at such a distance from the floor plate underneath that the flow of dry air can be sufficiently even. This distance is therefore only geared towards optimal equalization of the dry air. It is thereby achieved that the dry air can lift the skeins of thread from the holding arms without them becoming confused.
  • a double-decker strand yarn carrier 4 which can also be used as a single carrier for centrifugation thanks to a coupling device.
  • the strand yarn carrier 4 is fastened in a boiler 5 of a treatment apparatus by means of a mechanical holding device consisting of a screw spindle 11 with a handle 12.
  • the strand yarn carrier 4 consists essentially of a central central dome 6, to which a total of four levels of supporting rods 2, 3 are fastened via radial holding arms 7.
  • the yarn rods 2, 3 of each level are arranged concentrically to one another, and radially adjacent support rods 2, 3 can be offset in height in a known manner.
  • the distances between the interacting levels of support rods 2, 3 or the distances between the support arms 7 that belong together can be reduced and enlarged with the aid of a telescopic device 9, which can be actuated, for example, by means of a handle 10.
  • This change in the distance is not used to be able to treat strands 1 of different dimensions or shrink yarns; rather, it is more inseparable Part of the invention for gentle centrifugation of the yarn strands 1.
  • the strand yarn carrier 4 is surrounded by a cylindrical jacket 15, which is divided into individual segments.
  • the segments are attached to the support arms 7. With this jacket 15 it is possible to supply liquor or dry air for optimal results and to optimally support the yarn strands 1 during centrifugation.
  • the boiler 5 shown in FIG. 1 is the boiler of a through-flow dryer, preferably a dryer operating in several phases, which first frees the yarn strands 1 from the excess moisture with air blows that flow from top to bottom, then with warm air warmed and then dried under vacuum.
  • the warm air is supplied, for example, via the pipeline 14 and passed through a distributor base 16 to the upper end of the strand yarn carrier 4.
  • the cross section between the strand yarn carrier 4 and the bottom 16 must be sufficiently large.
  • the dry air penetrates the yarn strands 1 hanging on the support rods 2, 3 and leaves the boiler 5 via the pipeline 13. This direction of movement of the air from bottom to top allows the support points of the thread strands 1 to dry on the support rods 2.
  • the air speed is set so that the skeins of thread 1 lift 4 to 5 cm from the upper support rods 2 without getting confused.
  • the design of the bottom 16 at the lower end of the strand yarn carrier 4 has a very advantageous influence on the air flow and the drying results that can be achieved flows through the entire width of the cross-section evenly and without swirls.
  • the bottom 16 has three perforated bottom plates 17, 18, 19.
  • the bottom plate 17 - based on the flow of the yarn strands 1 from bottom to top - is conical and covers the inflow opening in the bottom 16. It is relatively roughly perforated.
  • the next floor panel 18 already has a finer perforation.
  • the top floor plate 19 has the finest perforation.
  • the distance between the top floor plate 19 and the underlying floor plate 18 is chosen so that the flow of dry air can be sufficiently even and calm in this intermediate section, so that eddies that can confuse the yarn strands 1 are avoided.
  • the direction of the dry air can then be reversed, i.e. H. the dry air is supplied via line 13 and discharged via line 14.
  • the dry air passes through the yarn strands 1 from top to bottom.
  • the same structure also results in the dyeing process if the strand yarn carrier 4 with the yarn strands 1 is inserted into the boiler of a dyeing apparatus.
  • reversal of the direction of flow of the liquor ensures that the skeins of yarn 1 lift off the upper yarn rods 2, so that the support points are also colored uniformly, the jacket 15 ensuring optimum flow of the liquor.
  • the fleet can be heated by means of a heater 20.
  • a comparable structure also results when the filled strand yarn carrier 4 is inserted into the drum of a centrifuge.
  • the distance between the associated holding arms 7 and thus between the respectively associated support rods 2, 3 is reduced so much that the innermost ones Support rods 2, 3 hanging yarn strands 1 can be supported under the action of the centrifugal force on the jacket 15 or on the drum wall of the centrifuge or on the outer yarn strands 1 already resting there. In this way it is avoided with certainty that the inner hanging strands of yarn 1 are overstretched during centrifugation and thereby damaged.
  • Fig. 2 shows a schematic plan view of a pivotable mounting of the support rods 2, 3 and the jacket 15 on the radial support arms 7. Since the support rods 2, 3 are no longer removed, the placement of the yarn strands 1 is considerably simplified. On the free side of the support rods 2, 3 and the jacket 15 there is a closure 8 which resists the centrifugal force. In the simplest case, these are pins 8.1, which are inserted into corresponding bores 8.2 on the associated support arm.
