Definitions

  • the invention relates to a method for mercerizing fabrics and knitted fabrics of the type mentioned in the preamble of the main claim. It also relates to an apparatus for performing this method.
  • DE-PS 118.359 a method for the mercerization of tissues is known, which is carried out under pressure for the purpose of preventing the edge penetration of the fabric in a way corresponding to the duration of the contracting action of the lye on the fabric threads.
  • DE-PS 119.427 which contains an addendum to patent 118,359, it is proposed that the textile material be impregnated during tensioning.
  • a liquid-permeable drum jacket is provided, in the interior of which the mercerizing liquor is held, which can reach the textile material lying on the pipe jacket through radial openings in the tube jacket and which grinds against the wall of a trough-like counter-bearing.
  • the trough-like counter bearing is designed as a perforated upper wall of a lye trough, the lye being intended to reach upwards against the force of gravity to the curved upper wall between the drum shell and the counter bearing forming the counter bearing.
  • DE-PS 639.367 which defines the generic term of the method according to the invention, a device for mercerizing fibers in a loose state with a perforated drum and a liquid-permeable pressure belt is known, the textile material being fed to the upper section of the drum, on this section with Mercerizing liquor is sprayed and the lower section is sprayed with water or weak liquor through radially and partly upwardly directed nozzles.
  • the inside of the drum itself is equipped with suction boxes to suck the lye and water through the textile material and the pressure belt.
  • the object of the invention is to safely and sustainably avoid the edge sagging of the textile goods during mercerizing, in particular in the case of knitted fabrics, but to achieve complete and short-term impregnation of the textile goods with simple means as well as sustainable removal and recovery of the Strong lye without dilution by leaching water or weak lye.
  • the invention provides the features of the characterizing part of the main claim.
  • the features of the process subclaims serve to improve and further develop the process steps of the main claim, while the device claims provide advantageous training point out the means to carry out the procedure.
  • the advantage of the method according to the invention can be seen in the fact that a simple closed drum shell can be used, furthermore that by pressing the textile material against the drum shell before or at the latest at the start of immersion in the mercerizing solution it is guaranteed in any case that with the first Contact of the textile material with the alkali is already an intimate attachment of the textile material to the drum shell, which may preferably be provided with a surface which is known per se and which prevents shrinkage.
  • the leaching is still carried out while the drum shell is being looped through the textile material while pressing the textile material onto the drum shell in such a way that the dehydration of the textile material is still in the wide-spread position of the textile goods between the drum jacket and the pressure belt. If the textile material leaves the drum jacket, it is de-leached and there is no longer any risk of the edge jumping in. - It is even more important that the immersion of the textile goods in the lye results in an intensive wetting of the textile goods over a short distance, followed by an action of the lye on the textile goods after the wetting section in the lye bath. On this route, excess lye runs undiluted from the textile goods and the pressure belt into the tub while the leaching water or the weak liquor in the upper drum section is taken along by the textile material and the pressure belt and is collected separately from the mercerizing liquor.
  • the device according to FIG. 1 has a drum 2 with drum casing 2a which can be rotated about the axis 1 in the direction of the arrow P and to which the deflection rollers 3, 4 are assigned on one side in the vicinity of the horizontal H.
  • the drum 2 is also surrounded by deflection rollers 5, 6, 7, 8, a pressure belt 9 being further wound around these rollers around the rollers 3, 4 and the drum 2.
  • This pressure band is a liquid-permeable band provided with small holes or woven from metallic or other suitable threads.
  • the web-shaped textile material 10 is pressed against the drum casing 2a by the pressure belt 9.
  • the textile material web enters the device in the direction of arrow 11, partially wraps around the roller 4 and is pressed against the drum jacket in the section between this roller 4 and the entry region 12 of a trough 14 filled with mercerizing liquor 13 above its alkali level 15 Suitable surface to prevent shrinkage of the textile goods Way can be formed.
  • the pressure belt 9 with the same-running textile material 10 resting on the drum jacket 2a is passed through the alkali 13, the alkali impregnating the textile material 10 over the entire surface as it passes through the pressure belt 9.
  • a squeeze roller 16 can be provided behind the trough 14.
  • the de-leaching device 17 In the respective upper area of the drum jacket and thus mirror image or approximately mirror image of the horizontal H, the de-leaching device 17 is provided, the nozzles 18 directed against the pressure belt 9 and the textile material web for a de-leaching agent, e.g. B. water or weak liquor.
  • the nozzles 18 can be covered by a hood 19, the front wall 20 and rear wall 21 of which rest with their lower end on the pressure belt.
  • the textile material web lies against the drum jacket 2 by the pressure belt 9 in such a way that even during the de-leaching itself no edge penetration of the textile material web can occur, so that the textile material leaves the device in the direction of arrow 22 without the danger a further jump in.
  • a liquid-permeable pressure belt 9 is again used.
  • the textile material 10 arrives in the direction of arrow 111 to a deflecting roller 104, the textile material in turn being between a trough 114 Mercerizing liquor 113 and this deflection roller is pressed by the pressure belt 9 against the drum jacket 102a.
  • a squeeze roller 116 can also be arranged again behind the flat trough 114.
  • the wrap angle of the drum 102 which rotates in the direction of the arrow P around the axis 1, is more than 180 ° to the de-leaching device 117 with de-leaching nozzles 118, which are arranged above the first quadrant I of the drum shell 1.
  • the pressure belt and the textile material web wrap around the roller 103 when leaving the device, between which and the roller 104 a collecting and stripping plate 123 for de-leaching liquid can be provided.
  • a complete soaking of the textile material with mercerizing lye takes place in the trough 14 or 114.
  • the textile material passes through an action zone of the lye on the textile material.
  • Excess mercerizing liquor also runs undiluted on this route back into trough 14 or 114.
  • the water or weak liquor added to the upper drum section is removed by the textile material or the pressure belt 9 taken in the direction of rotation of the drum 2 and can thus be recovered separately from the Mercerisierlauge in the trough 14 or 114.
  • the embodiment according to FIG. 2 is particularly advantageous for this.
