  • the invention relates to a yarn tying device for a
  • Yarn processing machine with a Fadentränkhunt for filling with a watering liquid for wetting a multifilament yarn to be soaked and one of the Fadentränkhunt in a yarn path of the multifilament yarn downstream thread guide element having a thread channel, wherein the thread channel has a cross section which is dimensioned such that when passing through with The impregnating liquid wets the multifilament thread through the thread channel, which builds up the impregnating liquid into the multifilament thread, and also a yarn processing machine with such a thread tying device.
  • BESTATIGUNGSKOPIE In making yarns by means of a yarn processing machine, it is often necessary to soak the yarns with a liquid to alter the properties of the yarns. For example, yarns are soaked with a liquid to impregnate the yarns. When the yarns are multifilament yarns, the problem arises that the impregnating liquid used for soaking does not completely penetrate between the individual filaments of the multifilament yarn. As a result, untreated areas remain between the individual filaments of the multifilament yarns.
  • PTFE polytetrafluoroethylene
  • the thread For soaking, the thread is usually passed through a trough in which the impregnating liquid is kept. Within the tub, a Fadenumlenkvoriques is present under a formed by the drinking liquid impregnating liquid level, so that the thread can be led out again after completely soaking with the impregnating liquid from the impregnating liquid. As a result, the thread always absorbs a maximum amount of impregnating liquid. A dosage of the absorbed drinking liquid is not possible.
  • the absorbed drinking liquid can subsequently be partially thrown off the thread again in the threadline of the thread, for example due to acceleration-related migration processes, or accumulates partially before the nozzle to be subsequently passed through. The latter can, especially if it is If the impregnating liquid is an air-curing material such as PTFE, it will cause problems in the operation of the yarn processing machine.
  • the invention has for its object to provide a thread tenter, which avoids the disadvantages of the prior art, in particular, a disturbance of the operation of a yarn processing machine with the thread tenter is to be avoided by deposits.
  • a yarn tying device for a yarn processing machine has a Fadentränkhunt for filling with a impregnating liquid for wetting a multifilament yarn to be impregnated and a Fadentränkhunt in a yarn path of the multifilament yarn downstream thread guide element.
  • the thread guide element has a thread channel, wherein the thread channel has a cross section which is dimensioned such that builds up the impregnating liquid in the multifilament thread einpressender pressure when passing through the impregnated liquid impregnated multifilament thread through the thread channel.
  • the yarn impregnation chamber has a yarn inlet opening, wherein the yarn inlet opening is formed as a hole in a wall region of the yarn impregnation chamber forming a bottom region of the yarn impregnation chamber.
  • the hole is always below a level of impregnation liquid level formed by the impregnating liquid when the filament chamber is filled with the impregnating liquid.
  • the filling of the Fadentränkhunt can be made so dosed with the impregnating liquid that the amount of impregnating liquid is absorbed by the multifilament thread through the held in the Fadentränkhunt impregnating liquid from the multifilament thread, a desired dosage of wetting of the multifilament thread with impregnating liquid corresponds.
  • the latter can be regulated by the height of the impregnation liquid level in the filament chamber. The higher this impregnating liquid level, the longer the multifilament thread runs through the impregnating liquid and the more impregnating liquid is taken up or carried along by the multifilament thread.
  • the amount of impregnating liquid applied to the surface of the multifilament yarn can also be metered in this way.
  • the amount of impregnating liquid offered to the multifilament yarn as it passes through the impregnating liquid ie existing, can be, in particular, less than the maximum amount of impregnating liquid that can be absorbed by the multifilament yarn. That is, it may be less than the capacity of the multifilament yarn. It can be adjusted so that the absorbed impregnating liquid amount so that virtually no impregnating liquid is thrown off the multifilament yarn in the further yarn path of the multifilament yarn. Disturbances of the operation of the yarn processing machine by depositing impregnating liquid are prevented. Furthermore, a straight thread guide through the thread-tying device is made possible by the thread-tying device according to the invention, which leads to a reduced thread tension.
  • the multifilament yarn is impregnated through and through the yarn-threading device according to the invention and not only wetted in the outer region of the multifilament yarn.
  • the latter is caused by the fact that the multifilament thread through the im Thread channel when passing through pressure, ie by the thus pressed between the filaments of the multifilament impregnated impregnating liquid is vented. This pressure increases with increasing thread passage speed through the thread channel, so that the thread-tapping device according to the invention is particularly well suited for use in
  • the impregnating liquid is thereby under a pressure of e.g. several bar pressed into the spaces between the filaments of the multifilament thread.
  • the yarn tying device according to the invention is suitable for impregnating any multifilament yarns.
  • both multifilament threads of synthetic fibers e.g. Glass, plastic or carbon fibers as well as natural fibers, e.g. Cotton or silk, to be soaked.
  • Both twisted and untwisted multifilament yarns can be soaked.
  • the multifilament yarns to be soaked can rotate during the passage of the yarn tentering device according to the invention, so that impregnation with the yarn tying device according to the invention can also be carried out in a yarn or twisting machine as a yarn processing machine during the yarn production process or twisting process or subsequently.
  • the cross section of the thread channel can proceed as follows. First, a theoretical thread diameter can be calculated. This can be done by considering the number of parallel filaments in the respective multifilament yarn and their diameter assuming a densest packing in a cylindrical arrangement and assuming the resulting diameter of the corresponding cylinder as the theoretical thread diameter.
  • the theoretical thread diameter or thread cross section thus corresponds to the cross section of the thread, which would result if the thread only consisted of a single thread Filament would exist. From this theoretical thread diameter, the cross section of the thread channel is calculated by multiplication by a factor, for example, to take into account the amount of liquid present on the surface of the multifilament thread when passing through the thread channel in the dimensioning.
  • the cross section of the thread channel can then be selected according to the diameter thus obtained.
  • the thread channel (pressure channel) must happen. How much of the impregnating liquid is pressed together with the multifilament thread through the pressure channel depends on the concentration of a solid substance in the impregnating liquid, which adheres to the multifilament thread after passing through the thread through the thread-tying device and hardening the impregnating liquid and of the desired application amount or thickness this solid substance on the multifilament thread. The higher the concentration and the smaller the desired application amount, the smaller the cross section of the pressure channel is selected.
  • the cross section of the pressure channel can be, for example, 1.5 to 3.5 times as large as the theoretical thread cross section.
  • a thread channel for multifilament thread made of glass is smaller than a thread channel for eg polyester, which is to be soaked with the same concentration and same application at the same titer, concentration and application amount.
