Definitions

  • the invention relates to a method for drying textile material in the form of yarn spools or also reel-winding, and an associated device according to the preamble of claim 3.
  • HF drying Another method of drying textile goods that has also been known for a long time is HF drying.
  • HF drying of bobbins and the like these are after the preceding wet treatment was always first removed from the carrier device and used individually for mechanical pre-dewatering in a centrifuge. After centrifuging, the bobbins of thread have again been placed individually on a conveyor belt which has passed them through an HF field.
  • the HF field was located in a tunnel-like facility, which made it possible to extract the moisture released during HF drying by means of a gas stream.
  • the handling of HF drying just described is very labor intensive in contrast to handling for through-flow drying.
  • HF drying is also associated with a not inconsiderable consumption of electrical energy if the entire moisture contained in the textile goods is to be dried off after a wet treatment.
  • HF drying is far superior to through-flow drying in terms of the end result, since the uniformity of the residual moisture does not depend in any way on the uniformity of the winding density; Even almost extremely different winding densities can be used to achieve a consistently uniform, always reproducible and otherwise precisely adjustable residual moisture by means of HF drying.
  • the uniformity of the residual moisture remaining after a drying process in a yarn package or the like is an almost indispensable prerequisite for trouble-free further processing of the textile goods.
  • the invention is therefore based on the object of demonstrating ways and means which make it possible to get by with the favorable handling of through-flow drying and yet the excellent uniformity of the residual moisture of the HF drying to reach.
  • the invention provides for the drying process to be carried out in two stages.
  • the first stage consists of through-flow drying and the second stage consists of HF drying, the latter also having to be carried out in a special new form, namely as "radial" HF drying.
  • the further drying namely the HF drying, is usefully carried out until the hygroscopic equilibrium is reached, which is the ideal case for the further processing of the textile goods.
  • An essential feature of this procedure according to the invention is that between the through-flow drying and the HF drying, the textile material no longer has to be repacked, in order to be done by HF drying as before, in the form of individual spools of thread on a conveyor belt by an HF -Train drying tunnel.
  • the textile material can be subjected to the HF drying without changing the package shape as a whole, without having to use excessively high electrical energies for the HF drying.
  • this is due to the fact that most of the moisture is already removed in the course of the first drying stage, namely through-flow drying, which is associated with extremely favorable handling, and without paying attention to achieving uniformity of drying at all should be.
  • any non-uniformities in the through-flow drying are completely equalized in the subsequent HF drying, even if the winding density is uneven.
  • the HF drying can be carried out without using excessively high electrical energies, because it is carried out as a "radial" HF drying and in this the HF field only has to penetrate the thickness of the yarn packages.
  • the method according to the invention thus actually achieves drying uniformity, as was previously only possible with overdrying and subsequent long-term storage.
  • this favorable result is also achieved in conjunction with very cheap handling, which was previously not possible.
  • the favorable result without any impairment of the strength and all other special properties of the yarns which was not the case with overdrying previously carried out to achieve uniform moisture, and without the use of excessively strong HF fields is achieved.
  • the through-flow drying should expediently be carried out to such an extent that a moisture of essentially 15% can subsequently be determined in the textile material, which can be reduced to the desired final value by means of HF drying.
  • the starting point is a textile goods container of the type previously used for through-flow drying.
  • the first part of the drying process according to the invention namely through-flow drying, is carried out in this textile goods container.
  • a textile goods container is also provided, which, however, is designed with regard to the special drying, namely for this purpose in particular HF electrodes and the possibility of suctioning off the moisture released by the HF drying.
  • the coil carriers which are to be used in the textile goods container used for through-flow drying, can also be used unchanged for HF drying, the HF electrodes must be turned on number ago to be matched to the number of coil columns of the coil carrier; this coordination naturally also affects the geometrical arrangement of the HF electrodes.
  • the textile goods container used for HF drying is identical to the container provided for through-flow drying, provided, however, that the only textile material container then has the HF electrodes in an appropriate number and arrangement.
  • the textile goods container used for HF drying is identical to the container provided for through-flow drying, provided, however, that the only textile material container then has the HF electrodes in an appropriate number and arrangement.
  • there is the possibility of providing a separate textile goods container for HF drying so that a total of two textile goods containers are provided, which are coordinated with one another to such an extent that only the bobbin is removed from the textile material container used for through-flow drying and into those of the HF drying serving textile goods container must be used.
  • a conventionally designed textile goods container 1 is placed on a foundation 2 or the like.
  • This textile goods container 1 is expediently a pressure-resistant container and closed at the top by means of a lid 3, which is either completely removable or can at least be opened so far that the interior of the textile goods container 1 is fully accessible.
  • a connection 5 is provided for supplying a gas stream.
  • a corresponding discharge connection 6 is provided relatively high on the textile goods container 1. From the supply connection 5 extends into the interior of the textile goods container 1 and up to a little above the inner bottom region of the textile goods container 1, a standpipe 7, the interior of which serves to continue the supplied gas flow and which also serves as a receiving bearing for the textile goods carrier, which in the exemplary embodiment here as Coil carrier 8 is formed.
  • the coil support 8 consists essentially of a hollow column body 9, which is continued at one end in a hollow plate 10 and which is inserted with its free lower end into the upper inner end of the standpipe 7.
  • So-called coil columns 11 extend downward from the underside of the plate 10.
  • the coil columns 11 are formed by perforated sheet metal "cans" 12 welded to the underside of the plate 10.
  • the coil carrier 8 is removed from the textile goods container 1 and its plate 10 is loaded onto one the other document.
  • a centrally perforated plate 14 made of electrically non-conductive material is inserted into the interior of the cans 12 and communicates with the cavity of the plate 10 via its opening 15.
  • the winding coils 13 are inserted into the interior of the cans 12, the winding or coil cores 16 of which are broken.
  • the cans 12 are closed at their free end by means of a further centrally perforated plate 17 made of electrically non-conductive material to prevent the winding coils 13 from falling out.
  • the bobbin 8 equipped in this way is then inserted into the textile goods container 1.
  • the gas supplied via the supply connection 5 reaches the interior enclosed by the winding cores 16 and from there through the textile material through the perforated cans 12 into the interior of the textile material container 1 and from there via the discharge connection 6 to the outside again.
  • the feed connection 5 and the discharge connection 6 can be connected to one another via a circulation line, not shown, into which a pump for circulation purposes, a heater and a water separator should be installed.
  • 1 HF electrodes 18 are provided in the interior of the textile goods container, which are connected to one another via connecting plates 19 and are, in principle, insulated from the container base 4. At least one of the connecting plates 19 is expediently guided through the housing base 4 to the outside, in a sealed manner, and is connected to an HF generator 20, which on the other hand is connected to the textile goods container 1.
  • the RF electrodes 18 are arranged in a number corresponding to the number of coil columns 11 in the container 1, at the same time corresponding to the spatial arrangement of the coil columns 11. This means that the HF electrodes 18 are always inserted into the cavity enclosed by the perforated sleeves 16.
  • the HF generator 20 is switched on after switching off the auxiliary units belonging to the throughflow drying, and the connection 6, which was originally used for removal purposes, and the other connection 5 originally used for supplying purposes, are connected to a device for suction, not shown, so that the moisture released by means of HF drying can be removed from the inside of the textile goods container.
  • the device shown in Figure 2 differs from the device shown in Figure 1 actually only in that in the device according to Figure 1 with 5 be drawn connection for the supply of gas for flow drying in the case of Figure 2 is a connection for the supply of gas as a carrier medium for the moisture released in the HF drying.
  • the textile goods container 1 according to FIG. 2 in the embodiment evident from there, is a textile goods container which serves only for HF drying.
  • a textile goods container serving exclusively flow drying is also required. This can then be designed, for example, in accordance with the textile goods container of FIG. 1, when the HF electrodes 18, the connecting plates 19 and the HF generator 20 are removed.
  • the result of the drying according to the invention is independent of the device used in each case, namely the use of perhaps only a single textile goods container or maybe two successive textile goods containers, one for flow drying and the other for HF drying, always a dried textile material of extreme uniformity with regard to Residual moisture.
  • the residual moisture can be practically any value that is to be achieved, including the hygroscopic balance.
  • the electrodes 18 are shown as hollow electrodes, the upper ends of which are open, so as to enable a fluidic connection to the hollow interior of the plate 10.
  • the electrodes 18 can also be designed as solid rod electrodes, the outer diameter of which, however, must then be matched to the inner diameter of the winding cores 16 in such a way that an annular gap remains free which is in communication with the hollow interior of the plate 10.
