Definitions

  • the present invention relates to a method for finishing felt-free wool. of wool fibers.
  • wool gradually becomes matted during washing or in general after prolonged contact with water, i.e. the individual fibers in woolen fabrics lose their elasticity and crimp and the textile material is compacted.
  • wool items must either be cleaned chemically or washed extremely gently - certainly unfavorable conditions at a time when all items should be washable with the washing machine as universally and easily as possible.
  • 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 this process control is that the bath volume can be reduced as a result and a reduced air mixing can take place on the surface of the bath.
  • the disclosed device is not suitable for the finishing of fiber strands, in particular the felt-free finishing of wool fiber strands, but it must be possible to define concentration gradients that must be precisely set during the treatment process, or it must be possible to set a precisely defined concentration drop in the treatment bath as the treatment duration progresses to be able to.
  • the system proposed in FR-2 359 233 is particularly suitable for treating textile webs with treatment solutions which show no or only a very weak chemical reaction with the solid fiber material, ie the concentration of the treatment solution does not change or only slightly, as is the case with continuous impregnation or dyeing. If there is to be a stronger interaction between the so applied fleet and the textile goods, this takes place outside the application device, for example in a subsequent heater, dryer or steamer.
  • GB-PS 586 020 proposes wool or wool fibers in an acidic solution of potassium permanganate with a pH ⁇ 2, preferably in a pH range of 1.5-1.7, for a period of 1-2 minutes to treat a liquor ratio of 1 kg wool to 14 liter liquor.
  • this treatment only leads to acceptable results if either the wool is washed intensively before the treatment, or if it is provided with a wetting agent so that the wool fiber is holistically separated from it in the short treatment time of approx. 1 minute Wetting solution is penetrated.
  • the method described has not proven itself in practice, since an enrichment of the wetting agents washed out of the wool has resulted in the felt-free finish being impeded by excessive brownstone precipitations and corresponding inequality.
  • the method described in GB-PS 586 020 is not suitable for continuous processes. Therefore it will only examples of discontinuous batch treatments are given.
  • the wool is proposed. briefly treat the wool fibers for a felt-free finish with an essentially strongly acidic, aqueous solution of potassium permanganate.
  • the wool fiber can be finished in a felt-free manner in accordance with the known and required standards, without the fiber trunk being damaged.
  • the concentration of potassium permanganate in the reaction solution is preferably 0.5-3 g of potassium permanganate per liter of solution, while the concentration of technically concentrated sulfuric acid (52%) is 15-40 g per liter of solution.
  • the treatment time or the contact time of the aqueous potassium permanganate solution with the wool resp. the wool fibers is 5-20 seconds, preferably 5-10 seconds.
  • the wool fibers are made in that the same, preferably in the form of wool slats, together with an essentially strongly acidic, aqueous potassium permanganate solution through an essentially closed through-channel or. a flow channel with inlet and outlet opening is (are) passed through.
  • a flow channel with inlet and outlet opening is (are) passed through.
  • the packing density of the wool slats in the continuous channel, respectively. the channel is such that the reaction solution is also transported to the wool ridge essentially at a constant relative speed.
  • a liquor ratio in the pass-through channel is preferably selected, which is 6-9 l / kg wool.
  • Fig. 1 the reaction sequence of the felt-free finishing of wool or. of wool slats in a flow channel according to the invention. shown a closed flow channel.
  • tube 5 produces a strongly acidic, aqueous potassium permanganate solution.
  • an aqueous potassium permanganate solution 2a together with an aqueous sulfuric acid solution 2b, containing a wetting agent, such as ethylene oxide adducts, are fed into the mixing tank 5 and briefly mixed to form a homogeneous reaction solution 7. This is then immediately fed into a feed basin 3, where the solution 7 is brought into contact with the wool comb 1.
  • a potassium permanganate solution 2a was used, the concentration of which is 50 gr KMnO 4 / l.
  • the concentration of the sulfuric acid solution 2b supplied is 35 gr of technically concentrated sulfuric acid (62%) per liter of solution.
  • the mixing ratio between streams 2a and 2b is 1:18 in the selected example.
  • approximately 2 gr / l of a polyphosphonic acid was added to the sulfuric acid solution. This prevents the precipitation of manganese dioxide (MnOz), which makes correct surface treatment possible in the first place.
  • the wool comb 1 is now guided, for example, via a driven transport roller 9 together with the reaction solution through an inlet opening 11 into a closed flow channel 13 which, as shown in FIG. 1 a, has a rectangular cross section.
  • the solution as mentioned above, is preferably mixed with a commercially available wetting agent. Since the packing density of the wool ridge in the pass-through channel 13 is relatively large, 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. In the present example the packing density is approx. 100 gr wool per liter channel volume and the chosen liquor ratio is approx. 6.5 l reaction solution per kg wool.
  • the wool comb 1 When leaving the continuous channel or of the closed channel 13 at the outlet opening 15, the wool comb 1 is drawn off via take-off rollers 17 and, at the same time, the fully reacted reaction solution contained therein is squeezed out.
  • 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 and fed to the catchment basin 3, or else recycled or neutralized and fed to the waste water.
  • 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 vessel 3 fresh reaction solution 5, whereby a largely constant concentration gradient through the entire device is guaranteed 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. In the selected example, the amount of reaction solution 7 continuously fed to the feed vessel 3 is approximately 4.4 l / min. while at the same time 656 gr wool per minute are passed through the trough 13.
  • the response time resp. the contact time of the reaction solution with the wool by corresponding length of the channel, respectively. the gutter 13 and / or by the speed at which the wool comb 1 through the gutter, respectively. the channel 13 is passed can be influenced.
  • the contact time or the response time is only a few seconds, such as 5-10 seconds. be.
  • the volume of the reaction solution can be kept very small, i.e.
  • a treatment liquor with a volume of 5 to 12 liters can be used on 1 kg of wool sliver.
  • this value depends on the packing density in the flow channel.
  • the liquor ratio can be kept constant along the entire channel, for which it is necessary that the feed 7 of reaction solution or. to fleet corresponds to the supply of woolen roving 1.
  • the packing density it can further be ensured that the relative speed of the liquor to the wool can be kept constant within the channel 13.
  • reaction device By means of the reaction device according to the invention shown in FIG. 1, it is moreover also possible to treat any textile or non-textile, fibrous draws 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 the fibers. individual fibrils of the textile or non-textile goods is limited, but not, for example, as mentioned above, the fiber stem (cortex) is attacked by the reaction solution.
  • the reaction device according to the invention shown in FIG. 1 also has the great advantage that no pumping or conveying devices have to be provided for conveying the reaction solution, since this is also conveyed as a result of the set packing density by conveying the textile goods to be treated. 1 clearly shows that the terminal overflow edge 19 has a substantially higher level than the reaction solution in the feed basin 3. If, for example, the packing density were chosen too low, or in the case of an unclosed flow channel, the reaction solution would constantly flow backwards and in Conveying the reaction solution with the textile goods would not be possible.
  • FIG. 2 in turn shows a further embodiment of a reaction trough proposed according to the invention.
  • the closed channel 13 is shown, the pass-through channel no longer being designed to rise upward in a straight line, but rather being semicircular in the transport direction of the wool comb 1 to be treated.
  • Both the feed basin and the extraction device are designed essentially analogously to the device in FIG. 1, but a catch basin 15 with a drainage channel 19 is provided at the end of the flow channel 13 in FIG. 2.
  • the advantage of the reaction device according to FIG. 2 is that, due to the very large radius of curvature of the through-channel 13, the friction of the wool sliver 1 is greatly reduced.
  • the friction caused by the tensile action by means of the rollers 17 can be further reduced by the walls 13 in the through-channel having longitudinal grooves.
  • FIG. 3 shows a further preferred embodiment variant of the device according to the invention according to FIG. 2, 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 base 10.
  • the peripheral surface 45 of the rotating body 41 and the inner bottom surface 10 now result the trough 12, the flow channel described according to the invention.
  • 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, upstream 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. 3 is analogous to the device according to FIG. 1.
  • the rotation device according to FIG. 3 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. If the wool ridges are very loose, resp. are easily tearable, it is possible to 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 sliver to the reaction liquor is largely constant.
  • the device according to FIGS. 3 and 4 can be used analogously to the devices according to FIGS. 1 and 2 wherever a textile or non-textile material has to be briefly equipped with a highly reactive reaction solution, the reaction only on the surface of the Good things have to be done.
