Definitions

  • the textile material travels in a continuous form through the central suction conduits of the two injectors into the outer conduits of the same where the treatment fluid is injected through regulating devices which permit variation of the fluid flow quantity supplied to each injector be tween 0% and 100% of the total fluid flow, and, in that way, the suctional power of each injector.
  • This determines the forward feeding of the fabric in the direction which corresponds to the injector with the greater suctional power, and the opposite injector with the smaller drawing power produces a slowing down and compactation effect on the fabric.
  • the present invention refers to a device for the Wet treatment of textile matters, and more strictly speaking, for the treatment of the same in rope form.
  • This permits the application of various wet treatments, such as bleaching, dyeing, etc., in a continuous way, be it at atmospheric pressure, be it at temperatures above 100 C. That way the formation of puckers, and extensions or the lengthening of the fabric which are being produced in the wet treatments, is eliminated, so that the present invention is specially suitable for the wet treatment of synthetic fibre fabrics.
  • One of the purposes of the device of the present invention is therefore, to avoid such drawbacks.
  • the device of the present invention comprises essentially two central suction injectors which inject the treatment bath, arranged opposite each other, i.e., with their outlet mouths disposed in front of each other, and which are provided with means to vary to each injection the fluid flow of the bath which is injected, from 0% to independently the one from the other.
  • the first effect is achieved by having each injector act alone during a determined time period, for instance, of several minutes. This causes the fabric movement to be periodically reversed, thus avoiding the formation of puckers and ripples.
  • the other effect is achieved by having the two injectors act simultaneously, but by suitably regulating the liquor flow which passes through each of them, so that the fluid quantity from one of the injectors is notably greater than that from the other injector.
  • a relaxation effect of the tensions in the fabric in rope form is obtained, thus preventing the elongation of the fabric.
  • the fabric in rope form is given a certain compactness, What is very important, especially when dealing with fabrics made of synthetic fibres or of mixtures thereof, to obtain, at suitable moisture and temperature conditions, a better quality of finished product.
  • the above arrangement of the two opposed counteracting injectors may be applied to the concrete case where endless fabrics in rope form are totally, or not totally, immersed in the dyeing bath, be it in containers which work at atmospheric pressure, or be it in closed containers which operate at temperatures higher than 100 C.
  • the above cited arrangement of the opposed counteracting injectors permits, on applying it industrially, the treatment of the fabric in rope form in a continuous way, be it a wetting treatment, fulling, degreasing, desizing, bleaching, dyeing, washing, anti-felting treatment, and chemical finishing. It is also feasible to carry out an impregnation with appropriate products in order to perform later a steaming treatment followed by wet chemical developing and washing treatments, including shrinking operations through steaming.
  • These treatments may include several of above cited operations which are carried out successively and in a continuous way.
  • you may arrange, successively and in the necessary numbers, several of those groups made up of two opposed counteracting injectors.
  • Each one of those injector groups may be fed with a determined treatment fin id which may be liquid or in the form of steam or gas.
  • the suitable regulation of the fluid quantity injected by the opposite injectors allows, in addition to making it possible to avoid elongations in the fabric, the varying of the fabric forward stepping speed so as to synchronize the fabric speeds within the totality of the injector groups, i.e., within the injector groups which are arranged in series, as in above case of continuous treatments.
  • the apparatus which covers the present invention is especially designed for the wet treatment of fabrics in rope form, it may also be successfully applied to the treatment of textile materials in other forms, such as synthetic fibre cables, threads, etc., with all types of gases or liquids.
  • FIG. 1 shows a schematical view of a device according to the present invention, for the wet treatment of fabrics 1 in rope form, in an open container.
  • FIG. 2 shows a schematical view of another embodiment of the present invention, for the wet treatment of fabrics in rope form, in a closed container.
  • FIG. 3 shows, also schematically, an arrangement for the continuous treatment of a fabric by means of liquids.
  • FIG. 4 shows another diagram of a treatment arrangement, which is similar to the one shown in the foregoing figure, but it is designed to operate with fluids which are in the state of vapour, steam or gas phase.
  • FIG. 5 shows a general diagram of a treatment installation composed of several treatment modules such as those of the FIGS. 3 and 4, in order to carry out many successive and continuous treatment operations as above explained.
  • the essential feature of the device which is the subject of the present invention, consists in the way of arranging two Venturi injectors 1 and 2, where the suction effect takes place along their central tubing 3 and 4, respectively.
  • Such suction effect is caused by the injection of a fluid under pressure into their respective outer conduits 5 and 6, where the injectors are positioned in opposite directions, i.e., with their mouths in front of each other, and are provided with means for individually adjusting the flow quantities of the treatment fluid which pass through each one of them, between 0% and 100% of the total fluid flow.
  • the textile material which has to undergo a continuous treatment for instance a fabric 7 arranged in rope form, is caused to pass through the suction tubes 3 and 4 of the two injectors 1 and 2 which are placed in position opposite each other.
  • the flow of the treatment fluids injected into each one of the injectors is suitably adjusted so that the difference between the dynamic pressures created by their opposing suctional effects caused in the one or other injector on the fabric 7 produces a movement of same in the direction in which the treatment liquor is injected with the higher pressure, while the action of the injector in front is to produce a relaxation effect on the tensions created in the fabric by the first injector.
  • the treatment container or tank 8 is open and has the general shape of a U. At each of the ends of the two arms of the U there are bends 9 and 10, which, extend from a point beneath the treatment liquor level 11 in the container 8 and terminate with their ends being positioned opposite each other at a certain distance, thus constituting the central suction tubes 3 and 4 of the two injectors 1 and 2, each of the respective injection conduits of which is made up of outer casings which are joined with each other by an intermediate tubing segment 12.
  • bend 9 has an opening 13 at its top, provided with a hermetic closing flange 14 which serves for the introduction and extraction of the rope-shaped fabric 7, which after having been made to pass through the above cited suction conduits of the injectors is joined at its ends to form an endless fabric rope which settles down in the interior of container 8 forming folds 15.
  • the treatment bath contained in the container 8 is made to flow within a closed circuit, and is extracted out of the container 8 by means of a pump 17 which is driven by an electric motor.
  • the treatment bath is thus caused to flow through a heat exchanger 19 which is provided with inlet pipes for admitting in steam for heating, and cold water for cooling.
  • the treatment liquor is injected into the two outer conduits 5 and 6 of both injectors, of course, having first passed through each controlling valve 22 and 23.
  • the dyeing bath or any other treatment liquor which, as it has been said, is impelled by the pump 17 reaches the injectors 1 and 2, and the ratio of their flow quantities is controlled at will by means of the respective controlling valves 22 and 23.
  • suction strengths proportional to those flow quantities are created in the corresponding central injector conduits 3 and 4.
  • the controlling valve 22 is opened and the controlling valve 23 is closed, then only in injector 1 will be produced a suction effect while injector 2 will remain inactive, so the fabric rope 7 will be impelled forward in a clockwise direction, while it will move in a counterclockwise direction if the controlling valve 22 is closed and the controlling valve 23 opened.
  • both controlling valves 22 and 23 are opened at the same time so that the treatment bath flow quantity which reaches injector 1 is several times larger than that reaching injector 2, then the fabric rope 7 will be moved forward in a clockwise direction, but will undergo a slowing down action on passing through the second injector 2, whereby elongation of the fabric will be avoided and a compactation effect will be produced.
  • the device shown in FIG. 2 is similar to the one which has been just described, the difference being that the treatment container 24 is closed, so that pressures higher than atmospheric pressure may be reached, and, therefore, it is possible to work at high temperatures.
  • the ends of the two arms of the U-shaped container are joined, thus a sole tightly closed enclosure is formed with the bends 25 and 26.
  • the closed treatment bath circulation circuit comprises an expansion vessel and, preferably, a device 28 for extracting samples so as to enable one to carry out exact treatment control, and, finally, a mixing vessel 29 to allow two similar devices to work simultaneously together and to reach a perfect equalization in the treatment effects in both devices.
  • the treatment :bath may cover the inlet opening of the injectors, so that the action thereof may produce a compound suction effect, i.e., not only on the fabric but also on part of a flow quantity which is a function of the injector nozzle diameter.
  • the wet treatment device shown in FIG. 2 carries a shunt pipe 34 in which an adjustable bypass valve 35 is inserted between two points of that device which are near to the outlet of injector 2 and to the inlet of injector 1, across the jackets 30 and 31 of the one and other arm of the wet treatment device.
  • various treatment modules such as shown in FIG. 3 when the treatment fluid is a liquid, or such as shown in FIG. 4 when the treatment fluid is a gas, or a vapour or steam, are used.
  • the treatment module shown in FIG. 3 comprises two injectors 1 and 2, which are positioned in opposite directions in the way above described.
  • the tank 36 is filled with the treatment bath.
  • the treatment bath is impelled by the pump 37 towards the injector 1 passing through the pipe 38 and the valve 39, and by the pump 40 towards the opposite injector 2 passing, in turn, through the pipe 41 and the valve 42.
  • each injector 1 and 2 receives the gaseous fluid at a preset ratio, through the respective adjusting valves 46 and 47 of the pipe 48.
  • the pipe 48 comes from a tank which is filled with gaseous fluid under pressure, and the pipe 49 which comes out of the chamber 50 which surrounds the perforated zone 51 which is located between both injectors is provided with a scavenger 52 which eliminates the condensate.
  • FIG. 5 shows an instance of an embodiment of a continuous thread bleaching plant where the cited thread, after having been fed into the system, is passed through a first impregnation module 53 similar to that in FIG. 3, comprising the two injectors 1 and 2, a return pipe for the return of the residual bath to the tank 36 containing the impregnation liquid, an adjusting system for the regulation of the liquid flow into the opposite injectors and means of dosification to ensure the quantity and concentration of the impregnation bath, and a bath temperature adjusting system, not shown in the drawing, as well.
  • a first impregnation module 53 similar to that in FIG. 3, comprising the two injectors 1 and 2, a return pipe for the return of the residual bath to the tank 36 containing the impregnation liquid, an adjusting system for the regulation of the liquid flow into the opposite injectors and means of dosification to ensure the quantity and concentration of the impregnation bath, and a bath temperature adjusting system, not shown in the drawing, as well.
  • vapourization module 54 similar to that one in FIG. 4, likewise provided with a set of opposed injectors 1 and 2 the purpose of which is to detach the oxidizing product and to release the suitable reaction to have the thread bleached.
  • washing modules or sets 55 are subsequently inserted, the purpose of which are to eliminate and neutralize in a contraflow the bleaching products.
  • the thread is passed through a drying modulus 56 where the moisture in the thread is eliminated by using compressed air. Then comes a finishing drying operation by means of a number of hot air drying units and of a final wind ing operation.
  • the performance of continuous operations on fabrics may also .be done, in accordance with the present invention, on synthetic fibre cables, threads, twines and fabrics, using any sort of gases or liquids.
  • a treatment device for the treatment of textile materials with a treatment fluid comprising first and second Venturi injectors of the central suction type, each of said injectors having an inner conduit and an outer conduit surrounding said inner conduit, said injectors being mounted with the outlets thereof opposed and the outer conduits thereof joined to form a connecting section; first means to supply said treatment fluid through said outer conduit of said first injector into said connecting section to create suction in said inner conduit of said first injector; second means to supply said treatment fluid through said outer conduit of said second injector into said connecting section in opposition to said treatment fluid through said first injector to create suction in said inner conduit of said second injector; means to pass said textile material through said inner conduits of said first and second injectors and said connecting section;
  • each of said injectors being bent and positioned such that the open ends thereof are below the upper level of said treatment fluid in said tank.
  • a device as claimed in claim 1 further comprising a U-shaped tank closed to the atmosphere, the free ends of said inner conduits of each of said injectors being sealingly attached to communicate with said tank.
  • a device as claimed in claim 4 further comprising a shunt line connecting the two legs of said U-shaped tank to provide passage therebetween of said treatment fluid.
