Definitions

  • the present disclosure relates to a process and apparatus for heat-treating textile material lengths, for example sliver-type textile materials which comprises introducing the material to be treated into a drying chamber, partially drying said material by contact heat transfer on the surface of heated rotating cylinder means and finally drying said material on the surface of at least one sieve drum means subjected to a suction draft or to a positive pressure wherein the treatment medium is passed through the material being treated.
  • the present invention relates to a process and apparatus for drying textile material lengths, for example sliver-type textile materials, wherein the material to be treated is passed in a drying chamber over rotating cylinders and heated up by means of contact heat transfer and by means of a gaseous treatment medium, such as drying air.
  • a gaseous treatment medium such as drying air.
  • the evaporated liquid is lead off by means of the treatment medium flowing around and through the material being treated.
  • Drying is affected by contact heat transfer at the surfaces of the material being treated. Drying is not uniform or at least not as uniform as it is when passing the air through the material. Contact heat transfer is of advantage for very wet textiles. If the surfaces are already substantially dehydrated by drying, further drying takes place very slowly since the liquid from the interior layers must first migrate to the surface. Furthermore, it is not possible with heated cylinders to guide the material without any tension. Thus full material shrinkage is not ensured.
  • Another object of the present invention is to provide an improved process and apparatus for drying textile materials which, in a wet condition, are impermeable to air but which become more permeable to air as they are dried down to a certain moisture content.
  • a further object of the present invention is to provide for a completely tensionless material guidance on the sieve drums to allow the material to shrink fully during drying.
  • the airpermeable textile material can then be finally dried on sieve drums by passing the treatment medium, for example air, through the material and with a high evaporative power.
  • an apparatus comprising heated cylinders at the inlet of the drier housing followed by sieve drums subjected to a suction draft or to an excess pressure, as guiding elements.
  • a blower device is correlated to these sieve drums in a well known way which produces the partial vacuum and/or the excess pressure in the sieve drums and which ensures the circulation of the treatment medium in the drier housing.
  • a device for example a pair of rollers, by means of which the textile material can be overfed to the first sieve drum.
  • a suction roller can also 'be used.
  • an instrument for measuring the air-permeability and/ or the moisture content between the heated cylinders and the sieve drums As a feeler for measuring the air permeability, the suction roller with which a material overfeed can be obtained, may be used. Here it is necessary only to measure the air quantity drawn in by the suction roller. For measuring the humidity, a pair of rollers may be used in a well known way. Also, the material overfeed can be effected by this pair of rollers at the same time.
  • the measured value can now be eval uated either by adjusting the speed of the drier according to a certain air-permeability or by connecting the measuring instrument with a control instrument which regulates the speed of material passage according to the moisture content of the fabric and/r according to the air-permeability of the fabric.
  • FIG. 1 is a longitudinal section of the apparatus of the present invention
  • FIG. 2 is a cross section of the apparatus of FIG. 1 taken along line AA.
  • FIG. 3 shows the means for measuring the air permeability of the material being treated using a pressure difference
  • FIG. 4 shows the gauge used to measure the pressure dilference in accordance with 'FIG. 3;
  • FIG. 5 shows the moisture measuring system used in the present invention.
  • the apparatus of the present invention comprises a heat-insulated housing 1 in which heated cylinders are provided at the inlet and sieve drums 3 are disposed behind said cylinders.
  • a pair of rollers 4 is correlated for overfeeding the material.
  • the speed of the pair of rollers together with that of the heated cylinders 2 can be adjusted independently of the speed of the sieve drums 3.
  • fans 5 are correlated in a well known way (FIG. 2).
  • the material length 12 is alternately guided around the heated cylinders 2 thereby evaporating part of the moisture.
  • the material length which is now air-permeable can then be overfed by means of a pair of rollers 4 on the sieve drums 3, so that the material is free to shrink fully during the subsequent final drying stage.
  • overfeeding will be effected by having the subsequent sieve drums run at a speed which is, by the desired percentage, slower than that of the heated cylinders 2 and the pair of rollers 4. In this manner full shrinkage of the fabric or of the other textile materials is ensured.
  • an absolutely uniform drying is effected which is usually only obtained with sieve drum driers, that is with driers in which the air is passed through the material.
  • the handle of the material is soft and the material is voluminous. The undesired luster and the boardlike handle which is the result of drying on heated cylinders is not encountered with this treatment.
  • the shaft 13 is provided with a bore 15 and a tube 14 in communication with said bore.
  • an additional tube 16 is disposed external of the sieve drum 3, that is, on the side of the drum covered by the material being treated.
  • the tube 16, as well as the drum axle 13 provided with bore 15 are in communication with a liquidfilled U-pipe 17 shown in FIG. 4, arranged on the outside and at the front end of the housing 1.
  • the U-pipe serves for indicating the pressure difference on both sides of the material being treated.
  • the pressure difference can be read from a scale 18 associated with the U-pipe.
  • the pressure difference is a measure of the air permeability.
  • the drum is driven by a hollow shaft 19 in communica tion with the drive assembly 9.
  • the speed of the drums can be adjusted by way of the handwheel 21 by means of the drive assembly.
  • FIG. 5 shows the moisture measuring system used in the present invention.
  • the moist material 12 passes through rolls 4, both rolls being fashioned as electrodes.
  • Two lines 22 transmit the electrical impulse to the combined moisture measuring and control device 25.
  • the degree of moisture is indicated on a scale 23 by means of an indicator 24.
  • the device 25 which is also fashioned as a control device, makes it possible to regulate the speed at which the material travels in accordance with the moisture present in the fabric.
  • the apparatus of the present invention can also be used for Thermosol-dyeing and for fiber setting.
  • the material which has been impregnated with the dyeing liquor is dried down to a residual moisture content of about 20 to 30% and on the sieve drums the material is then finally dried and heat-set.
  • the device offers the advantage that a predrying duct with infrared radiators may be dispensed with.
  • a process for drying textile materials which are substantially impermeable to air when containing a high degree of moisture which comprises introducing the moisture-containing material to be treated into a drying chamber, partially drying said material by contact heat transfer to air-permeability at a suction draft of about 50 to mm. water by conveying the material on the surface of at least one heated rotating cylinder and finally drying said material by connection heat-transfer by conveying the material on the surface of at least one sieve drum means subjected to a suction draft or to a positive pressure wherein a heated treatment medium is passed through the material being treated.
  • An apparatus for heat-treating textile materials which comprises a substantially closed housing, at least one cylinder means rotatably disposed within said housing at the inlet thereof, means for heating said cylinder means disposed in said housing at least one sieve drum means subjected to a suction draft or to a positive pressure r0- tatably disposed within said housing behind said heated cylinder means, inlet means for introducing the material to be treated to the housing and outlet means for removing the material.
  • roller means are used for measuring the humidity of the material being treated.
  • suction roller is used as a feeler for measuring the air permeability.
