Definitions

  • the present invention relates to a method for continuously treating textile materials in general.
  • the known bleaching and dyeing methods essen strictlytially comprise one or several successive immersions of the fabric with the treatment agents of each particular case, and a further reaction phase which may be as thermal energy contribution in the form of steam, or as a rest at ambient temperature during a rather extended time.
  • a further reaction phase which may be as thermal energy contribution in the form of steam, or as a rest at ambient temperature during a rather extended time.
  • the time required for such treatments is rather lengthy, either in view of the long cold reaction period in the rest methods, or to the unavoidable waiting times between the immersions and the treatment phases.
  • stabilizing agents On the other hand, owing to the said waiting times, it is neces­sary to add stabilizing agents to the treatment baths to prevent decomposition of the treatment substances. These stabilizing agents in turn stop down the reagent activity and lead to a part of same being lost because of becoming unable to react.
  • the present invention removes the above draw­backs of the previous art procedures and provides a new method for the continuous treatment of textile materials as specified above, by moving the material through the in­side of a treatment chamber along a path defined by return rollers, the material being subjected within the said chamber to the action of one or several treatment agents which are reactive with one another and/or with the material, and to one or several contributions of kinetic and thermal energies to give raise to the said reactions, the method being characterized in that: - application of the treatment and thermal energy carry­ing agents is performed by pressure projecting or in­jecting polyfunctional fluids or instantaneous tran­sit, violent reaction compounds against one or both material faces, each said fluids being constituted of a component carrying the kinetic and thermal energies, and a component carrying at least one treatment agent, - the treatment and kinetic and thermal energy carrying components are contributed to the material in the proportions which are just necessaryy to complete the foreseen reactions, - carrier components for the treatment and energy con­tribution components are applied to the material in
  • the invention extends as well to an apparatus for carrying into practice the above defined method, com­prising a treatment chamber with continuous material input and output means, and means for conducting the said material through the inside of the chamber across one or several treatment stations.
  • the machine is characterized in that - at least one treatment station comprises one or several projecting devices for the treatment agents and extending along the whole width of the material to be treated, arranged to project one or several poly­functional compounds, as defined above, against at least one of the material faces, - each polyfunctional compound comprises at least one kinetic and thermal energy contribution component, and - the projecting devices are connected to impeller and dosing means for feeding the polyfunctional fluid com­ponents in the necessary relative proportions to carry the reactive agents to the desired depth within the material thickness, such that a reaction takes place in situ and instan­taneously of the reagents with one another and/or with the material, with the maximum performances of the chemical, kinetic and thermal energies.
  • the kinetic and thermal energies contributing fluid can be used as the kinetic and thermal energies contributing fluid.
  • Such fluids may show a vapour contents of the carrier liq­uid for the energy contributions, of up to a supersatura­tion of the contribution fluid, preferably between condi­tions of saturated vapor to superheated vapor.
  • the moisture contents may be any under the 100 % saturation value, and at any rate small enough such as to permit eventual evaporation of a liquid constituting the chemical contribution agent carrier.
  • the liquids from which the thermal contribution fluid is formed and the liquid containing the chemical contribution fluid may be different, or preferably the same, water being used as the main support for these fluids.
  • the chemical contribution fluid may be selected from gases, liquids, solids and the physical com­binations of same, and in either case the fluid may be carried in a carrier liquid which, in turn, may be the thermal contribution support itself.
  • the chemical contribution fluid is a gas or a solution, dis­persion or emulsion of the appropriate reagent in a liquid vehicle having a boiling temperature of between 60 and 250°C, preferably between 80 and 150°C.
  • the kinetic and thermal ener­gies contribution fluid to contain vapour of the same liq­uid used as a vehicle for the chemical treatment agents, and this in a proportion located under the saturation point, and at temperatures higher that the boiling point of the said liquid.
  • the temperature of the thermal energy contributing fluid is preferably selected such that it makes possible an spontaneous evaporation of the liquid used as a vehicle or carrier for the chemical contribution fluids, in order to attain a suitable concentration of the chemical energy contribution agents onto the material, and fast reactions, to advantage instantaneous, of the said agents with one another and/or with the material or sub­strate.
  • the moisture contents, the temperature and the kinetic energy are controlled such that they are enough to provide the evaporation of the chemical con­tribution carrier, and give to the ensemble a thermal energy level enough to give a fast chemical reaction of the chemical contribution agents with one another and/or with the textile material.
  • the textile material may be subjected to several successive applications of polyfunctional fluids during its travel through one single treatment chamber, so that the textile material is subjected to successive and different treat­ments.
  • the method ac­cording to the invention can be conducted within a single chamber in the inside of which several different and suc­cessive treatments may be effected because the contribu­tions of the several components intervening in the said treatments are performed directly in situ, onto or into the fabric material.
  • the chamber can be merely designed as a housing to isolate the treatments as regards the outer atmosphere, there being no need to provide for a given energy consumption for holding the in­side of the chamber to a given conditioning level, as is the case with the known practice.
  • the apparatus comprises a generally cubic box 1 having input devices 2 and output devices 3, for a fabric 4 which is to be hand-­led therein and, accordingly, is moved in the direction as indicated by arrows 5.
  • the inside 6 of box 1 constitutes the treatment chamber for the fabric or material 4, this latter being guided through a long path within the box, by means of successive rollers or cylinders 7,8 alternately arranged at two different, respectively upper and lower levels. These rollers, or some of them, are connected through suitable gearings with driving means provided with speed regulating means of a conventional type, not shown, to draw the fabric 4 with the speed required for the treat­ments to be performed.
  • Means for applying the treatment agents for the fabric 4 are located by the cylinders 7,8 and indicated generally with 9; these means will be described further on.
  • the application of the treat­ment agents in the method and the apparatus according to the invention is performed in an essentially dry mode, with little or not at all flow of fluids towards the cham­ber bottom, by making use of the new concept of "polyfunc­tional fluids" simultaneously contributing the chemical, kinetic and thermal energies in the amounts which are just necessary to soak the material and perform therein the en­visaged reactions.
  • the means 9 for applying the treatment agents are constituted by double action injectors adapted to provide jets or any suitable shape, between circular and flat shapes, and arranged to fall upon the whole width of the fabric 4.
  • the polyfunctional fluids sprayed by the in­jectors 9 and their interactions with the fabric or material are in accordance with the features described in the introduction.
  • the strength of the reagent or reagents in the chemical contribution fluid is calculated according to the product strength over the weight unit of fabric to be treated, which is a function of the fabric traveling speed through the treatment chamber, as well as a function of the amounts of fluid which are to be applied thereto in either case.
  • the polyfunctional fluid can as well be gen­ erated starting from a chemical contribution component which, on being heated, is adapted to generate a thermal contribution phase which, through physical means and mixed with the original chemical contribution fluid, builds up with this later the polyfunctional fluid according to the invention.
  • the double action injectors 9 are fed with the chemical contribution component through ducting 10 from tanks, not shown, wherein the previously prepared, chemical contribution component is stored; such tanks, as it is appreciated, do not require to have the great volumetric proportions which are common in the previous art procedures.
  • the kinetic and thermal energy contributing com­ponent for example steam at a temperature selected in ac­cordance with the previous specifications, is fed to the very double action injectors 9 or to adjacent injectors, not shown, by means of ducting 11 derived from a steam network generally present in the plants of the art to which the present invention appertains.
  • the flow rates and pressures at which both components are fed to the injec­tors are preferably regulated such as to adapt the mix­ture proportions to the features of the material being treated.
  • the admixture of both polyfunctional fluid components may be performed in prechambers with no pressure or with a light superpres­sure, the admixture being thereafter compressed such that the necessary pressure for obtaining a desired penetra­tion, is attained at the instant of the application of the fluid onto the fabric.
  • the reactions take place, according to the invention, in an essentially ins­tantaneous mode.
  • the injec­tors of each cylinder may be used to project polyfunc­tional agents corresponding to different treatments.
  • the functional assemblies of the several cylinders could be fed with the chemical and energetic contributions necessary to perform all of the several operations of a treatment for bleaching and whitening fabrics which, in this way would become finished in a single pass through the apparatus shown.
  • such a treatment may be performed by using a chemical contribution component having the composition: Caustic soda, 48° Bè 240,0 cl Moistener - detergent (1) 40,0 g Stabilizer (2) 40,0 cl Sodium silicate 8,0 cl Potassium persulfate 20,0 g Ca, Mg, Fe ion sequestrating agent 2,0 g Hydrogen peroxide, 200 vol. 120,0 cl wherein all of the values are referred to 1 liter of water.
  • a chemical contribution component having the composition: Caustic soda, 48° Bé 240,0 cl Moistener - detergent (1) 40,0 g Stabilizer (2) 40,0 cl Sodium silicate 8,0 cl Potassium persulfate 20,0 g Ca, Mg, Fe ion sequestrating agent 2,0 g Hydrogen peroxide, 200 vol. 120,0 cl wherein all of the values are referred to 1 liter of water.
  • the application is performed with a component ratio corresponding to 75 to 80 % dry weight of the dry fabric.
  • the energy requirements are contributed as saturated steam at 3 Bar, such that the whole is applied under a pressure of 2 Bar.
  • This treatment may be performed at only one of the apparatus upper cylinders and, if desired, may be fol­lowed by a similar treatment, performed in the same condi­tions as above at the second cylinder, making use of the composition: Caustic soda, 48° Bè 120,0 cl Moistener - detergent (1) 20,0 g Stabilizing agent (2) 20,0 cl Sodium silicate 4,0 cl Potassium persulfate 8,0 g Ca, Mg, Fe ions sequestering agent 1,0 g Oxygen peroxide, 200 vol. 60,0 cl Optic brightener 2,0 g, wherein all of the values are referred to 1 liter of water.
  • the moistener (1) may be anysuitable product available in the market and complying with the required features for a suitable formulation. Making use of the two above formulations, in the described manner, particularly good results have been obtained with a residence time of about 20 seconds in the ensemble of the two operations.
  • composition of the second bath has a minimal difference as to the persulfate contents, this must not be understood such that the successive treatments in steps of the procedure following to one another must be more or less similar.
  • thoroughly different treatments can be developed at successive stages or cylinders and which, while they are thoroughly com­patible in accordance with the invention, they would be unimaginable at all in the field of the known treatment techniques.
  • the second composition has a strength of about one half that of the first one.
  • the temperature at the inside of the chamber 6 my be different to that under which the polyfunctional fluids are applied.
  • this may be performed by taking the more from the proper heat of the thermal energy component, suitably overdimensionated the case arising, or by means of additional heat contributions by conventional means.
  • the admixture proportions of the polyfunctional fluids may be regulated on the basis of a detection of physical parameters on the fabric, either before, during or after either treatment.
  • Specially suitable parameters for such regulations are temperatures and temperature gradients at several locations of the fabric, moisture contents and moisture content gradients at several places of same, as an indicator of the presence of reagents or of an excess development of reagents, such as O2.
  • the data obtained by means of such detections can be dealt with by microprocessors to convert them in commands for regulating the fabric traveling speed, the polyfunctional fluids flow rates, the proportions of the components in these latter, etc.
  • the input to the cham­ber 6 is closed by merely a conventional thermal dam 2.
  • the hydraulic dam device 3 constituted by a tank 12 containing a liquid 13, a plunger inverter roller 14 for the fabric, and a bridge screen 15 the lower edge of which plunges into the liquid, thus separating the inside of chamber 6 from the outer at­mosphere.
  • the fabric is passed through the device as shown and is guided outside by a guide roller 16 and a pair of squeezing rollers 17, and thereafter passed to the follow­ing fabric handling stage.
  • the bath formed by the liquid 13 may be used to effect a washing of the fabric, for example to remove cot­ton sizing waxes, provided it is heated to a suitable tem­perature by means of a live steam input 18, and renewed by means of a fresh water input 19.
  • the ventilating ducts 20 having their openings distributed through the chamber 6 ceiling, converge into a collector 21 joined by a duct 22 to the drawing side of a radial impeller 23 allowing the gases and vapours gen­erated during the treatment reactions to be discharged through ducting 24 to a dispensing off or recovering plant.
  • the invention at­tains the above objects and advantages. Further, it can be said that owing to the absence of high squeezing ratio foulard units, the fabric is not crushed, which is of par­ticular advantage in most cases. Also, in the case of cot­ton fabrics, the invention thoroughly eliminates the im­purities called "tobacco" and permits to reach white levels equivalent to those resulting from the lengthy in­ dustrial processes of the known art.
