Definitions

  • the present invention relates to a device for essentially continuously treating a product conveyed by a reaction device with a reaction solution, a method for the continuous short-term treatment of a product with a reaction solution, the use of one of the devices for the treatment or the finishing of textile fiber strands, fiber draws, yarns, fabrics and the like, and in particular the essentially felt-free finishing of woolen drawstrings.
  • the present invention relates to the treatment of textile fibers, respectively. of ridges, skeins of yarn and the like in a treatment bath with a reaction solution, such as finishing or. Treating or finishing wool or of wool fibers to prevent the wool from matting during washing.
  • Such treatment or finishing processes take place either discontinuously in the so-called batch process or continuously, in that entire fiber strands or largely continuous fiber draws or. the textile goods are drawn over rollers through treatment baths to superficially with the treatment or finishing agent, respectively. the reaction solution to be provided.
  • the present invention is concerned with the second-mentioned so-called. Treatment process for textile goods.
  • the felt-free finishing of wool takes place, for example, with aqueous chlorine solution.
  • the reaction condition when treating the wool with chlorine solution can be selected in such a way that the above-mentioned conditions can be met without damaging the fiber stem of the wool.
  • the chlorine for the treatment of the wool has to be dispensed with, so that other chemicals or Processes for the treatment of wool are to be used, which normally do not correspond to the corresponding treatment or concentration conditions under the reaction conditions and concentration ratios chosen with the chlorine solutions. Effect on or on the wool fiber.
  • the gas chlorination bath which is preferably used in the chlorination of the wool and in which the wool is drawn into a bath with acidified hypochlorite solution via pad rollers has also proven to be unsuitable when using oxidizing agents for the felt-free finishing of the wool.
  • oxidizing agents for the felt-free finishing of the wool.
  • the concentration of the oxidizing agent in the treatment bath is also kept high, the attack on the wool fiber is too strong, which regularly leads to damage to the fiber trunk. Nevertheless, it seems to be important that the oxidizing agents chosen as alternatives to chlorine for the treatment of wool fibers are in relatively high concentrations or at least under strong acidic or strongly alkaline conditions must be present in order to enable a sufficient felt-free finishing of the wool.
  • a device for the continuous finishing of textile webs is known, the material to be treated, together with a treatment agent solution, passing through one or more longitudinally extended treatment containers in the same direction, the treatment agent being largely pulled out of the solution during the passage.
  • the proposed system is particularly suitable for treating textile webs with weakly concentrated treatment agent solutions, such as for dyeing or impregnating.
  • weakly concentrated treatment agent solutions such as for dyeing or impregnating.
  • such a system as described is hardly suitable for short-term treatment with highly concentrated reaction solutions, as is necessary, for example, for the brief felt-free finishing of wool webs.
  • FR-2 359 233 describes a device or a method for the continuous impregnation of textile threads, the threads being passed through individual tubes for the coating process.
  • the advantage of this system or process control is that the bath volume can be reduced as a result, and in addition a reduced air mixing can take place on the surface of the bath. Due to the "entrainment" of the liquid through the threads passing through the pipes, pumps can be dispensed with.
  • the disclosed device is not suitable for the finishing of fiber strands, such as the short-term felt-free finishing of wool fiber strands, but it must be possible to define concentration gradients that need to be precisely set during the treatment process, or it must be possible to progressively define a precisely defined concentration drop in the treatment bath To be able to set the duration of treatment. Also, there must be no accumulation of any disruptive components in the treatment bath, such as, for example, wetting agents or reaction-inhibiting substances, such as, for example, wetting agents present on the wool fibers, which enable the wool fiber to be quickly penetrated with the reaction solution.
  • any disruptive components in the treatment bath such as, for example, wetting agents or reaction-inhibiting substances, such as, for example, wetting agents present on the wool fibers, which enable the wool fiber to be quickly penetrated with the reaction solution.
  • the system proposed in FR-2 359 233 is particularly suitable for treating textile webs with weakly concentrated treatment agent solutions, such as for dyeing or impregnating.
  • weakly concentrated treatment agent solutions such as for dyeing or impregnating.
  • a system described in this way is hardly suitable for short-term treatment with highly concentrated reaction solutions, as is necessary, for example, for the brief felt-free finishing of wool webs.
  • Treatment or finishing of a good, in particular a textile good can be carried out continuously with a reaction solution, on the one hand working with relatively highly concentrated reaction solutions and on the other hand the contact time of the reaction solution with the good to be treated may only be brief.
  • this object is achieved by means of a device, in particular according to the wording according to claim 1.
  • the material to be treated together with a reaction solution via a feed device of a closed flow channel or. an essentially all-round flow channel with inlet and outlet opening is supplied, the material to be treated and the reaction solution together in close contact through the channel or. passed through the channel respectively. are promoted by an essentially filling packing density can be set in the channel or the channel such that the reaction solution as a result of the transport of the textile material through the continuous channel or. the flow channel is promoted.
  • the main difference to the system according to DE-OS 1 816 483 is that due to the close lateral contact of the side walls of the channel or the channel in the area provided for the conveyance of the goods, a relatively high packing density can be set, so that the reaction solution by the Transport of the textile goods through the continuous trough. the flow channel is promoted at the same time. The reaction solution is drawn into the channel from the feed basin and the resulting slight squeezing effect increases the penetration or wetting of the wool fiber at the entry opening.
  • DE-OS 1 816 483 either the treatment agent has to be conveyed through the reaction container by means of pumps or other conveying means, or the level at the entry into the treatment room has to be chosen higher than with a pull-off edge at the end of the treatment room.
  • the gutter respectively.
  • the flow channel is formed from a fixed, at least almost semicircular, essentially circular trough-like container, with a rotating body which is arranged in the trough and can be freely rotated.
  • the axis of rotation of the rotary body is preferably mounted so that it can rotate freely on the trough-like container in such a way that the central axis of rotation comes to lie in the center of the circular trough-like container.
  • the radius of the rotary body is to be chosen smaller than the inner radius of the trough-like container, and the width of the rotary body should be almost equal to the inner width of the container, so that between the peripheral surface of the rotary body and the inner container base is at least semicircular in the longitudinal direction essentially closed flow channel, respectively.
  • a gutter is formed with a rectangular cross section. The widths of the rotating body and the trough-like container should be such that a free rotation of the body in the trough is still possible.
  • the above-mentioned devices characterized according to the invention are particularly suitable for the treatment or the equipping or finishing of textile fiber strands, fiber trains, yarns, fabrics and the like, such as in particular wool combs.
  • the devices according to the invention are suitable for the felt-free finishing of wool or. of wool ridges.
  • Fig. 1 is a longitudinal channel and schematically an inventive trough respectively. a closed flow channel is shown.
  • a wool comb 1 is introduced together with the reaction solution 5 into a feed basin 3, in which the wool comb 1 is wetted with the reaction solution 7 collected therein.
  • the reaction solution 5 can be, for example, an aqueous oxidizing agent solution which is used for the felt-free treatment of the wool.
  • the solution is preferably mixed with a commercially available wetting agent.
  • Via a feed device 9, for example a driven one The wool sliver becomes a transport roller. 1 together with the reaction solution through an inlet opening 11 into the closed flow channel 13, which, as shown in Fig. La, has a rectangular cross section.
  • the reaction solution 7 is together with the wool ridge to the outlet opening 15 of the pass-through channel, respectively. of the closed channel.
  • the wool comb 1 is drawn off via a take-off device 17 consisting of take-off rollers and at the same time squeezes off the reaction solution present therein.
  • the reaction solution also emerging from the trough 13 passes via an edge 19 into a collecting basin 21, in which the used reaction solution 23 is collected. This is then either concentrated again via a line 25, fed to the catchment basin 3, or otherwise used, or fed to the waste water in a neutralized manner.
  • reaction solution 7 Due to the constant conveyance of reaction solution 7 through the continuous trough. the closed channel 13 must be continuously fed to the feed basin 3 fresh reaction solution 5, which ensures a largely constant concentration gradient corresponding to the consumption of the reaction solution through the entire device even without appropriate control. Due to the relatively high packing density of the wool sliver to be treated in the flow channel, a constant liquor ratio along the entire reaction path is further guaranteed.
  • the channel 13 can be selected.
  • the contact time or the response time is only a few seconds, such as 8 to 10 seconds.
  • Another advantage of the device according to the invention is that the volume of the reaction solution can be kept very small, ie, for example, a treatment liquor with a volume of 5 to 12 liters can be used on 1 kg of wool sliver. Of course, this value depends on the packing density in the flow channel.
  • reaction device By means of the reaction device according to the invention shown in FIG. 1, it is possible to treat any textile or non-textile fiber-like trains or strands with a reaction solution which have a high reaction rate with the textile or non-textile material to be treated. It is important that the reaction only to the outermost layer of fibers resp. is limited by fibrils of the textile or non-textile material, but not, for example, the fiber stem (cortex) is attacked by the reaction solution.
  • Fig. 2 is similar to Fig. 1, an upward straight extending gutter respectively.
  • a closed flow channel 13 is shown, but one wall of the channel is formed by a conveyor belt 35.
  • This conveyor belt 35 is an endless conveyor belt which is deflected via the two end rollers 33, a closed displacement body 31 preferably being formed centrally between the two conveyor belt legs, on which the conveyor belt 35 is arranged so as to be freely movable.
  • the advantage of arranging such a conveyor belt 35 is that the wool comb 1 through the pass-through. has better mobility through the closed channel 13, so that, for example, the pulling of the ridge due to excessive tensile force in the squeezing rollers 17 is prevented. If necessary, it is even possible to support or Drive the conveyor belt 35 in the transport direction of the wool, so that the conveyor belt 35 runs essentially synchronously with the rollers 17 and possibly with the roller 9 at the feed.
  • the lower wall of the flow channel 13 with an analog conveyor belt, so that two walls of the flow reaction channel can be moved in the transport direction of the wool sliver. This is particularly advantageous if the material to be conveyed through the channel is a very loose material that would tear even at relatively low tensile forces caused by the take-off rollers 17.
  • FIG. 3 in turn shows a further embodiment of the reaction channel proposed according to the invention.
  • of the closed channel 13 is shown, with the flow channel now no longer rising in a straight line, but rather being semicircular in the transport direction of the wool sliver 1 to be treated.
  • Both the feed basin and the extraction device are designed essentially analogously to the devices in FIGS. 1 and 2, but a catch basin 15 with a drainage channel 19 is provided at the end of the flow channel 13 in FIG. 3.
  • the advantage of the reaction device according to FIG. 3 is that, due to the very large radius of curvature of the through-channel 13, the friction of the wool sliver 1 is strong is reduced. The friction caused by the pulling action by means of the rollers 17 can be further reduced if the walls in the continuous channel 13 have longitudinal grooves.
  • FIG. 4 shows a further preferred embodiment variant of a device according to the invention, again in longitudinal section.
  • the starting point is a trough-like container 12 which has a semicircular base, the base being largely circular.
  • a closed rotary body 41 In the fixed trough 12 is a closed rotary body 41, the axis of rotation 43 of which is arranged in the center of the circular bottom of the trough 12 and is connected to the trough in such a way that the rotary body 41 is freely rotatable. It is essential that the radius r of the rotating body 41 is made smaller than the inner radius R of the container bottom 10.
  • the closed channel 13 which in turn serves for the wool comb 1 to be conveyed from the inlet opening 11 to the outlet opening 15.
  • the trough 12 has, at the end of the inlet opening 11, a projection 3, which forms the feed basin, and downstream of the outlet opening 15, an overflow edge 16 or. an overflow channel 19 for the removal of the reaction solution. Otherwise, the functioning of the rotary device according to FIG. 4 is analogous to the devices according to FIGS. 1 to 3.
  • the rotation device according to FIG. 4 is shown in cross section along the line II-II, it being clearly visible that the rotation body 41 is arranged in the trough-like container 12 in such a way that it practically fills the latter, but is nevertheless freely rotatable.
  • the continuous channel is. the closed channel 13 through which the wool 1 is conveyed is visible.
  • the rotary body 41 may be freely rotatable. In the case of sensitive goods, such as easily tearable textile goods, it is possible to also rotate the body. to drive the rotary drum 41 synchronously with the take-off rollers 17. It is also possible to provide the surface 45 of the drum 41 with transverse grooves, while the bottom 10 of the trough-like container 12 preferably has longitudinal grooves. Ultimately, for cleaning purposes, it is advantageous to arrange a trigger device 14 at the lower end of the trough 12 so that the channel or. the channel 13 can be emptied.
  • the speed ratio of the crest to the reaction liquor is constant and is 1.35 in the concentric channel region 13.
  • wool combs were equipped with various oxidizing agent solutions in a felt-free manner, such as hypochlorite solutions, permanganate solutions, etc.
  • various oxidizing agent solutions such as hypochlorite solutions, permanganate solutions, etc.
  • FIG. 6 two devices according to FIG. 4 are shown arranged one after the other in longitudinal section.
  • the wool ridge 1 is about the induction.
  • the cantilever 3 is immersed in the reaction solution 7 and drawn through the inlet opening 11 into a first semicircular reaction channel 13a.
  • This flow channel respectively.
  • the channel 13a is formed by a first container 12a having a semicircular base and the correspondingly rotating body 41a rotating therein, which rotates about the axis of rotation 43a.
