Definitions

  • the invention relates to a capacitive high-frequency continuous oven for drying textile fabrics, in particular knitted cotton fabrics, in which the fabric can be transported between the electrodes.
  • Capacitive radio-frequency ovens of the aforementioned type are known in a wide variety of embodiments (cf. e.g. DE-OS 29 41 845, 28 17 067) and have proven themselves well in the drying of textiles.
  • textile fabrics are repeatedly dried after various wet treatments. It is desirable that the fabrics, and in particular the knitted fabrics, shrink in the final drying processes in such a way that the end user only has to accept a small amount of residual shrinkage when washing and drying the fabric.
  • the object of the present invention is to design a high-frequency continuous furnace of the type mentioned at the outset in such a way that the shrink resistance of the fabrics treated with high frequency can also be increased.
  • This object is achieved in that a mechanical device for shaking the tissue during the drying process is arranged in the oven. Surprisingly, this results in a residual shrinkage of the tissue that is clearly below 5%. This effect may be due to the fact that the binding forces between the individual threads of the fabric at the weaving crossing points, which have already been loosened by the high-frequency heating, are further loosened by the additional mechanical vibration, so that the threads can shift and shrink as desired. Such a freely shrunk fabric is then relatively resistant to shrinkage later on.
  • a periodic impact device for example in the form of impact cams, which acts periodically on the conveyor belt and / or its support, can be provided as the mechanical shaking device. But it is also possible that the conveyor belt and / or its support is new to put them into vibrating vibrations.
  • a shaker for transporting the goods to be dried or to generate the vibrations using ultrasound.
  • the shaking frequency and / or shaking amplitude can be changed so that the shaking can be optimally adapted to the tissue in question.
  • a mechanical device for shaking the knitted cotton fabric 7 during the drying process is arranged in the high-frequency oven 1.
  • This shaking device can consist, for example, of motor-driven impact cams, as indicated by reference number 8, which strike against the support of the conveyor belt 5 or also from nozzles through which pulsating compressed air flows against the support and vibrates them together with the knitted fabrics.
  • the vibrating frequencies and vibrating amplitudes can be changed.
  • the shaking additionally loosens the binding forces between the individual threads of the fabric, i.e. an effect of high-frequency drying is still supported, so that a largely unobstructed shrinkage of the knitted fabric is possible during the transport and drying process.
