Definitions

  • the invention relates to a method (according to the preamble of claim 1) and an apparatus (according to the preamble of claim 7) for the discontinuous wet treatment of knitted or knitted textile material.
  • a device is known in particular for drying tubular textile material.
  • This textile material is first fed in strand form via a transport roller and fed through a water flushing pipe to a lower liquid drainage surface before it is inflated in a balloon for the first time and then fed to a pair of squeeze rollers with continuous treatment.
  • a number of wet treatment processes are also known (EP-A-229 889, GB-A-20 39 966 and GB-A-21 54 255), in which tubular textile material is continuously passed through a corresponding device and possibly passes through a liquor bath and inflated in a balloon shape using air.
  • a device for various types of wet treatment of a tubular knitted fabric is also known.
  • the textile material can apparently be treated continuously and discontinuously in a skid-like or U-shaped container, in the lower part of which a liquor bath is formed, from which the textile material is pulled out on one side, then inflated like a balloon and spread out, squeezed out and then is finally reinserted into the liquor bath on the opposite side of the container.
  • This treatment container thus discloses an internal division of the treatment container, which enables a completely different type of wet treatment than is required in the preamble of claim 1 of the present invention (in which a dwelling zone is penetrated in the lower container area and, inter alia, an immersion trough in the upper container area) .
  • knitted or knitted textile goods i.e. so-called knitwear
  • various adapted devices such as Reel skids, jet, overflow or similar treatment machines and devices colored or otherwise wet-treated.
  • the treatment in the form of a strand is predominant.
  • the problems with the flow of goods in the treatment device result from downtimes, grinding points, etc.
  • the causes for this can be in unsecured goods transport at low treatment temperatures, knots in the strand of goods in a storage dwell zone, furthermore in basic transport problems with extremely light or extremely heavy goods qualities and in the influence foam, dyeing aids and other chemicals.
  • All treatment devices have a direct influence on the quality of the goods to be achieved. If you go e.g. from an average treatment time of about six hours and a cycle time of two minutes, then the textile goods have to pass the transport devices, fleet feed devices, the goods store, etc. about one hundred and eighty times. Due to the resulting friction against the goods, there is an undesirable roughening and flossing of the goods surface. In addition, there is a continuous breaking or flexing of the goods combined in the form of a strand, as a result of which the surface of the goods is adversely affected.
  • the invention is therefore based on the object of providing a method of the type required in the preamble of claim 1, by means of which, with relatively simple constructive means and avoiding roughening of the textile surface, a uniform product distribution (distribution of the dye and other means to be supplied) and a more reliable one Textile circulation (goods transport) can be guaranteed.
  • this procedure according to the invention ensures that the textile material is particularly spread out in the area of the immersion trough, this knitted fabric can always be carried out in a completely spread form by the diving trough sufficiently filled with the treatment liquor.
  • This enables a particularly intensive wet treatment of this textile material, so that an extremely even distribution of the product to be applied to the textile material (dyes and the like) is ensured from the outset.
  • the use of a diving trough on the one hand and this widespread passage of the textile goods through the treatment liquor in the diving trough also lead to an extremely economical treatment method in which a relatively low liquor ratio can be used.
  • the textile material in the area above the immersion trough is mechanically dewatered to a predetermined residual moisture before it is reintroduced into the dwell zone in the lower container area via a - known per se - deflection and transport device.
  • This type of dewatering of the textile goods after a sufficient transport distance above the immersion trough also contributes to an accelerated and intensive distribution of the treatment products throughout the textile goods. Since a quick and even distribution of the treatment products in the textile goods (knitwear) is thus ensured, the entire wet treatment requires considerably fewer circulations within the treatment container compared to known designs, so that for an extremely gentle treatment of the goods surface and thus for the maintenance of the desired Goods character is taken care of.
  • the knitted or knitted textile material presented in the form of a tube is expanded into a balloon in the region between the immersion trough and the mechanical dewatering and made wrinkle-free.
  • the textile material presented multiple times and knitted flat is mechanically spread out in the area in front of the diving trough and aligned in its entrainment.
  • this treatment is particularly suitable for knitted fabrics made flat and in a broad form, which are generally several times as thick as normal circular knitted fabrics (tubular goods).
  • a strand treatment of this flat-knitted knitted fabric would lead to deformation, becoming lobed and felting, while the wet treatment according to the invention in a spread form maintains the desired rigidity of this type of textile and ensures an excellent surface quality.
  • a device for carrying out this method in which a first deflecting roller deflecting the textile material strand rising from the dwell zone and a second deflecting roller immersing the textile material in the treatment liquor are provided in front of the immersion trough, are characterized according to the invention by the feature indicated in the characterizing part of claim 7.
  • the device illustrated in FIG. 1 is used for the discontinuous wet treatment of knitted or knitted textile goods, which for the sake of simplicity is referred to below as knitted fabric 1.
  • This device contains a container 2, into which the knitted fabric 1 to be treated is fed in the usual way via a gallows-like feed device 3. If a sufficient amount of this knitted fabric 1 is introduced into the container 2, the front and rear ends of this knitted fabric 1 are sewn together in a known manner, so that the textile material 1 can circulate endlessly in the direction of arrows 4 within the container 2 in a broad state, for which purpose 1 in the upper right area of the Container 2 at least one known, driven transport roller 5 or a known transport reel is provided.
  • the upper region of the container interior forms a type of deflection zone 6 for the endlessly circulating knitted fabric 1, while the lower region of the container interior forms a dwell zone 7 for this knitted fabric 1.
  • the knitted fabric 1 is paneled into the dwell zone 7 with the aid of a known, reciprocating fold layer 8 arranged below the transport roller 5.
  • the dwell zone 7 is further preferably delimited by a sliding grate 9 serving as the bottom, indicated only by dashed lines, and by an installation body 10, likewise indicated only by dashed lines, provided approximately in the middle part of the interior of the container, to an open, J-shaped space at its inlet and outlet ends.
  • a diving trough 11 which extends transversely (perpendicular to the plane of the drawing in FIG. 1) over the interior of the container and in front of which a first deflecting roller 12 (deflecting into the diving trough which deflects the dwelling zone 7 from the dwelling zone 7) 11) is arranged, while a second deflection roller 13 is provided within this immersion trough 11, which immerses the knitted fabric 1 in a treatment liquor bath 14 present in the immersion trough 11.
  • these two deflecting rollers can also at least partially ensure that the knitted fabric 1 is guided in the center of the immersion trough 11 in a spread-out and central manner.
  • a mechanical dewatering device is provided, which in the case of FIG. 1 is formed by two squeezing rollers 15 known per se. These nip rollers 15 have a soft rubber jacket 15a on their outer circumference (preferably with a hardness of 30 to 45 ° shore hardness). The knitwear 1 passed between this pair of squeeze rollers 15 and partially wrapping around these rollers passes through the container 2 during its transport (arrows 4), and then via the transport roller 5.
  • the approximately perpendicular path between the immersion trough 11 and the pair of squeeze rollers 15 is used to inflate the knitted fabric 1 to a balloon 16 and to make it wrinkle-free.
  • a nozzle system 17 is provided, with the aid of which a suitable gaseous medium, in particular compressed air, water vapor, nitrogen or another inert gas, can be blown into the knitted fabric 1 in a controllable manner if it is in the form of a tube.
  • this nozzle system 17 can be connected to a blower 18 which, for example in the uppermost region of the container interior, can suck in gaseous medium (for example air or gas) for inflating the balloon 16 with the aid of a suction piece 19 known per se can.
  • gaseous medium for example air or gas
  • the treatment tank 2 is also associated in a known manner with a liquor circulation line 20 connected to the immersion trough 11 with a liquor circulation pump 21 and a built-in heat exchanger 22 for the provision of a treatment liquor which is controllable in quantity and temperature. Furthermore, it is generally advantageous to provide the treatment container 2 with a steam heating device, which is indicated only very schematically by arrows 23 and which can be used to heat the interior of the container to the required treatment temperature. This can involve both direct heating of the interior of the container and indirect heating.
  • the dewatering device can also be designed in the form of a so-called locking bolt system 24, in which three deflection rollers 25 in the transport direction (arrow 4) of the knitted fabric 1 are arranged so closely one behind the other that there are at least two sufficiently strong textile material deflections in order to achieve a sufficient drainage effect for the knitted fabric 1.
  • Whether or not a pair of squeeze rolls 15 as shown in FIG. 1 or a tie bar system 24 as shown in FIG. 2 is used in this wet treatment apparatus generally depends on the desired dewatering effect, i.e. With the help of the pair of squeeze rollers 15, a more controllable and stronger dewatering effect (squeezing effect) can generally be achieved than with the clamping bolt system 24.
  • the treatment device is illustrated primarily for the wet treatment possibility of tubular meshes 1, in which a balloon inflation path is provided between the second deflection roller 13 of the immersion trough 11 and the dewatering device 15 and 24, respectively is used, this balloon inflation section according to the example in FIG. 3 can then be omitted or can only be shut down if knitted fabric 1 'knitted and knitted flat 1' is to be wet-treated in this device.
  • a suitable mechanical spreading device 26 is arranged in front of the first deflecting roller 12 arranged in front of the immersion trough 11, which is preferably equipped with at least two known spreading and center guide rollers 27 for this type of textile material (knitted fabric 1 ').
  • two squeeze rollers 15 as indicated in FIG. 3
  • a tensioning bolt system 24 according to FIG. 2 can be provided as the drainage device above the immersion trough 11.
  • the treatment liquor to be supplied to the knitted fabric 1 is applied only in the immersion trough 11 onto or into the knitted fabric 1, 1 ', while the dwell zone 7 remains in the container 2 essentially free of any liquor, apart from any liquor residues that run off or drip off from the goods, these liquor residues are immediately drawn off with the aid of the liquor circulation pump 21 at the bottom of the vessel 2.
  • the knitted fabric 1, 1 'in this device After passing through the immersion trough to a residual moisture of about 100 to 250%, based on the weight of the textile fabric, the knitted fabric can be dewatered in a targeted and desired manner with the aid of the pair of squeeze rollers 15 or the clamping bar system 24 will.
  • the squeezed, excessive treatment liquor can run back down into the immersion trough 11 along the route ascending from the immersion trough 11 to the drainage device.
  • the knitwear 1, 1 ' is preferably successively circulated in the container 2 in at least two different treatment liquors, for example washing, dyeing, circulating in succession and separately to the diving trough 11. and rinsing liquors, wet treated.
  • the treatment liquors for the different types of treatment of an entire wet treatment process can be drained and renewed individually, depending on the procedure, but this is often not necessary, especially since the treatment liquor can renew itself between bleaching and washing.
  • the immersion trough 11 can be overflowed in the container 2, as is illustrated, for example, by FIG. 4, which essentially shows an enlarged section of the device according to FIG. 1 - In the area from the diving trough 11 to the pair of squeeze rollers 15 - shows.
  • the immersion trough 11 is provided with a siphon-like overflow pipe 28 through which the liquor level 14a in the liquor bath 14 of the immersion trough 11 can be adjusted.
  • This height adjustment of the liquor bath 14 can take place, for example, in that the overflow pipe 28 is rotated about its lower pipe axis 28a.
