Definitions

  • the present invention relates to a method for the heat treatment of a plurality of running yarns and a device suitable for this.
  • a large number of yarns that come from single-position units are folded into a narrow band and passed over a common heating device in the folded state and then further processed separately or collected on bobbins.
  • the yarns are preferably folded on a common delivery device before they enter the heating device.
  • the heating device preferably has a common delivery roller and a common take-off roller in order to move through them ratio to determine the change in length of the yarns in the heating zone.
  • Contact heaters such as e.g. Heating plates or fixed or rotating radiators.
  • a narrow band is a bundle of yarns in which the distance between the yarns is significantly less than the distance between the individual processing points, the so-called machine division.
  • the method according to the invention is preferably used in the hot twisting of yarns, in false twist texturing and in the stretching of synthetic yarns, especially pre-oriented yarns.
  • the method according to the invention permits economical, continuous hot twisting of yarns.
  • high-twisted yarns are desired in which the applied twist is calmed by a heat setting process.
  • Hot twisting is of particular importance for synthetic filament yarns made from smooth or textured filaments, for example from polyesters. However, hot twisting is also suitable for all other types of yarn, such as spun yarn from natural fibers or chemical fibers or also for monofilaments. Hot twisting devices can also be used to fold multiple yarns.
  • Hot twisting devices correspond to the multi-digit twisting machine known from the textile industry, with a heating device being arranged at each twisting point between the twisting spindle and the winding device.
  • Multi-digit devices for hot twisting are devices with significantly more than two twisting points, usually around 50 twisting points are arranged in a row.
  • the method according to the invention shows its advantages particularly in the case of multi-digit devices for the hot twisting of yarns with twisting spindles, heating and winding device, in which the individual twisting points are each arranged in a row.
  • the device then has a common heating device, which is preferably arranged at the end of the row of twisting spindles.
  • the row of winding devices is arranged parallel to the row of twisting spindles, the two rows are also preferably arranged one above the other or next to one another, or the two rows of twisting spindles or the winding units are in alignment arranged; the common heating device is then often arranged between these rows.
  • the threads 1 run high-twisted from the double-wire twist spindle 2 and are combined into a narrow band 4 via deflection elements 3, 3a.
  • This narrow belt 4 passes from the delivery unit 5 via the heating plate 6 to the take-off unit 7, and via further deflection elements 8, 8a to the winding 9.
  • the advantage of the method according to the invention resides in the restriction to a narrow common heater 6, which is passed by the narrow band 4 of the folded threads 1. This ensures that all yarns are exposed to a common fixing temperature.
  • the shrinkage properties of the yarns are determined via their speed ratio.
  • the method according to the invention is also used in false-wire texturing, especially in simultaneous stretch texturing.
  • the yarns are supplied and drained from the common heater, which has the preferred shape of the tube bundle, usually via individual supply units for each yarn.
  • the advantages of the method according to the invention are particularly evident in false-wire texturing machines, which consist of a large number of blocks of texturing points arranged one behind the other, each texturing point having a payout spool, a delivery unit, a heating and cooling device and a swirl device, optionally a second heating device and a second one Take-off unit and a take-up device, and in which all elements are arranged on one floor and all delivery and take-off devices, the swirlers and the take-up devices are accessible from one operating aisle.
  • Another application of the method according to the invention is in the drawing of synthetic yarns, especially highly pre-oriented yarns; in particular also in combination with twisting processes, such as those described in CH-PS 601 518, where high-twisted, fixed synthetic continuous yarns are made from high-speed spun yarns by first twisting these yarns in one and the same machine and then stretching them in a heating chamber and be fixed at the same time.
  • Fast spinning yarns are preferably polyester and polyamide yarns that are produced at spinning speeds of 3000 - 5000 m / min.
  • DE-OS 29 00 799 describes a similar method in which the thread tension in the balloon of the double wire spindle is so high that it causes the thread to be stretched; a fixation then follows continuously.
  • the hiding according to the method according to the invention can furthermore take place during slip or warping, where the yarns are in any case guided as a narrow band. All that is necessary here is to install a delivery and extraction unit and the common heater.
  • the method according to the invention leads to an economical procedure with low energy expenditure and thus also to a low heat emission into the environment. Furthermore, the investment and space requirements of the machines are reduced and operability is improved. Yarns produced according to the invention are distinguished by excellent uniformity.
