Definitions

  • the invention is concerned exclusively with finishing processes in which the ratio by weight of water plus finishing agent is low and particularly to such processes of the kind which are characterised in that the textile takes up all or substantially all of the available liquor during the impregnation step.
  • a pro cess which is characterised in this manner will hereinafter be referred to as a low liquor ratio finishing process of the kind concerned.
  • the heating step is performed by heating is performed by heating a bath of the liquor, and thus the textile contained therein.
  • This is not possible with low liquor ratio finishing processes of the kind concerned since there is little or no free liquor and the conduction and convection of heat through the impregnated textile is inhibited by the discontinuous nature of the liquid phase of the liquor.
  • One particular finishing process of the kind concerned utilizes foam forming qualities of a foaming agent as an additive to the liquor; the impregnation step is so performed as to foam the liquor within and on the surface of the textile. In this particular process of the kind concerned further difficulties arise in the heating step be cause of the heat insulating properties of the foam.
  • impregnated textile has a tendency to dry as it is heated and premature drying causes uneven treatment.
  • the present invention sets out to overcome the above-mentioned problems.
  • the present invention resides in a low liquor ratio finishing process of the kind concerned in which, during the heating step, the impregnated textile is heated while being moved in an atmosphere which is substantially or completely saturated with water vapour.
  • the said atmosphere is utilized as a heating medium for the textile and its associated liquor. This eliminates the problems of excessive evaporation, with consequent premature drying so that the temperature of the impregnated textile can be raised rapidly without risks of uneven treatment.
  • the level of water vapour in, i.e., the degree of saturation of, the atmosphere should not be so high as to result in excessive condensation onto the textile which would cause excessive dilution of the liquor with consequent formation of an excessive amount of free foam, where forming agents are used and/or uneven treatment.
  • the impregnated textile will be heated to a predetermined temperature during the heating step; in the case of dyeing this temperature is known as the fixing temperature.
  • the textile may then be cooled immediately or it may be maintained at the said temperature for a predetermined length of time during which the finishing agent takes effect.
  • the humidity of the atmosphere may he reduced once the aforesaid temperature has been attained so that a certain permissible amount of evaporation of water from the textile so effectively increasing the concentration of finishing agent therein to improve the level of treatment.
  • the effect of the liquor on the textile into which it has been impregnated may be modified, when desired, by the addition of an appropriate chemical or chemicals in vapour or atomised spray form to the atmosphere in which the heating step is performed.
  • the liquor contains dyestuffs which are active in alkaline neutral and acidic environments and the pH value of the liquor is adjusted accordingly by suitable additions to the atmosphere to render the dyestuffs active in sequence.
  • Chemicals which may be added to the atmosphere to modify the liquor for such a purpose are Ammonia, Acetic Acid and Formic Acid.
  • Additiona may also be made to the atmosphere to provide a carrier to increase the rate of migration of dispersed dyes into hydrophobic textiles; one such additive is Benzyl Alcohol.
  • Formaldehyde can be similarly introduced towards the end of a finishing process so as to enhance the fixation of, for example, direct dyes.
  • Addition is simple where the chemical additive concerned volatilizes below the boiling point of water i.e., at 100C where the process is performed at atmospheric pressure; however the chemicals may be injected in atomised form to assure rapid vapourisation. in the case of chemicals, such as Benzyl alcohol, their steam volatility facilites vapourization, Where the chemicals do not volatilize at the boiling point of water addition may be achieved by the use of wick devices.
  • the method ofobtaining the desired atmopshere may vary.
  • the water which is required to saturate the atmosphere to the desired extent in which the fixing step is performed is injected into a stream of air in the form of steam or atomised water and the air is circulated through a chamber which contains the textile. This air may be circulated through the chamber during the heating step and its temperature may be raised externally of the said chamber.
  • the heating step may be performed in a closed chamber.
  • a quantity of water which is sufficient to en sure substantial or complete saturation of the atmosphere in the vessel or system without drying of the textile when raised to the fixing temperature is incorporated in the finishing liquor and the volume of the said closed chamber is so selected as to ensure saturation of the atmosphere therein without drying of the textile.
  • the excess water evaporates as the temperature within and means for adding liquid or liquid vapour into air circulated by the circulating system.
  • FIG. 1 is a general perspective view partially cut away of one preferred machine in which the textile is tumbled in a rotatable horizontally journellad drum.
  • FIG. 2 is a section of an important part of the machine of FIG. 1.
  • FIG. 3 is a diagrammatic front view of an alternative machine for use where the textile is in the form of a rope, the front of the machine hving been cut away,
  • FIG. 4 is a section on the line BB in FIG. 3,
  • FIG. 5 is similar to FIG. 4 but shows a machine for use where the textile is in the form of a flat web
  • FIGS. 6, 7 and 8 illustrate modifications to the machines shown in FIGS. 3 to 5.
  • the machine shown in FIG. 1 and 2 provides a rotatable drum 1 which is perforated over its cylindrical wall and a cylindrical casing 2 in which the drum 1 is journalled.
  • the casing 2 defines a treatment chamber in which textile in the drum 1 is processed, the latter being rotated at low speed by an electric motor (not shown) at desired times to move the textile by a tumbling action and being provided on the interior of its cylindrical wall with axially extending lifters.
  • Access to the drum 1 is through an opening la which communicates with an opening 3a in the casing 2, the latter being closable by door 3 which is hinged to the casing 2.
  • a steam injector 4 is arranged to dishcarge into the lower part of the casing 2 outside the drum 1.
  • An external air circulating system is arranged to withdraw air from the interior of the casing 2 to heat it and recirculate it into the drum 1 by way of the access opening 1a.
  • the circulating system comprises a vertical chimney 5 which enters the cylindrical casing 2 tangentially of the latter.
  • the chimney 5 is provided with sensors 2Ia and 21b which extend into the casing 2 to sense the temperature and pressure respectively in the casing 1 and also with a damper 6 actuable by a piston cylinder unit 7 and a further damper 8 actuable by a piston cylinder unit 9.
  • the damper 8 controls the passage of air from the casing 2 into an exhaust duct 10 while the damper 6 controls the passage of air into a further part of the circulating system, viz. a duct 11.
  • An inlet of a filter unit 12 is connected to the duct 11 by way of a quick release connector 13 and the outlet of the filter unit 12 connects with the inlet of a. centrifugal fan 14 by way ofa duct 15 which incorporates a further quick release connector 16.
  • the filter 12 may be of any suitable construction and materiai; for example, open-cell expanded foam polymers, metal gauzes, sintered metals, metallic wool, fabric, paper or suitably arranged baffles may be arranged to constitute the filter elements.
  • the quick release connectors 13 and 16 permit the filter to be removed from the circulating system for cleaning or replacement when necessary.
  • the fan 14 is arranged to discharge into a heater box 17 which houses gilled tube steam heaters 18 and the heater box 17 in turn connects with the interior of the drum 1 by way of a duct 19 which is provided on a front wall of the casing Z, and discharges into the opening la by way of opening 20.
  • the discharge exit of the duct 19 is shown in section in FIG. 2. As can be seen this exit is closeable by means of a damper 20 which is actuated by a pair of piston cylinder units 200 shown in FIG. 1. When the damper 20 is open it is received against an inner transparent portion 3a of the the door 3 and air passing through the duct 19 is discharged into the interior of the drum 1 through the opening in as indicated by arrows in the drawings.
  • the heater box 17 is provided with an access door 22 for cleaning purposes and a door 23 is provided in the chimney 5 for these purposes.
  • the machine is also provided with a steam coil heating jacket 24.
  • the purpose of this heating jacket is as follows; in order to perform with optimum efficiency the heaters i8 have been designed to raise the temperature of the textile at a high rate and it is improtant that uneven heating of the textile and condensation in the machine are prevented.
  • the heating jacket 24 is arranged to heat the lower part of the casing 2 in which any condensate will collect.
  • the heating jacket 24 is designed to heat the said part of the casing 2, and also the remainder of the latter by conduction, at a rate which approximates closely to the rate at which the heaters 18 raise the temperature of the atmosphere in the casing 1 and hence the textile.
  • the heating jacket 24 thus reduces condensation by virtue of the'fact that the average temperature of the casing is maintained close to the temperature of the atmosphere within the latter; also it ensures that any condensation which odes occur is re-evaporated because it is so positioned to heat that part of the casing in which any condensation, e.g., such as may occur in the chimney 5, collects. Furthermore it greatly reduces the amount of heat which must be added to the atmosphere by the heaters 18. For example, consider a machine weighing 4,000 lb. and constructed from stainless steel containing a textile load of lb. of polyester yarn impregnated at a liquor/goods ratio of 1.5 l by weight.
  • the total quantity of heat required is equivalent to 86.4 lb of steam; of this only the equivalent of 16.4 lb of steam is required to heat the textile, the remaining quantity of heat is required to heat the machine and the majority of it can be provided by the heating jacket 24.
  • the heating jacket 24 can alternatively be supplied with cold water when the machine is to be cooled at the end of a process.
  • the machine is advantageously utilized for performing both the impregnating and the heating steps of a low liquor ratio finishing process of the kind concerned.
  • a spray bar which is arranged in the vicinity of the access opening 2a to discharge into the drum l'through the opening la.
  • the spray bar 25 is alternatively connectible to a pumped and metered source of liquor 260 or to a source of water as at 26b; when the latter source is effective water or other rinsing liquid sprayed into the drum and is also caused to reverse flush the connection between the spray bar 25 and the source 26a so as to prevent cross-batch contamination.
  • the spray inlet When a predetermined quantity of treatment liquor has been sprayed onto the textile the spray inlet is closed. The tumbling of the textile is continued so as mechanically work the textile to ensure even impregnation of the textile by the liquor; the tumbling also generates a foam where a foam forming additive is in use. During this time the drum remains isolated from the circulating system thus any liquor and in particular any foam, which becomes detached from the textile is prevented from leaving the casing.
  • the heating step comprises heating the textile while moving it in an atmosphere which is saturated or completely saturated.
  • fixing temperature In the case of dyeing heating of the textile continues until the socalled fixing temperature is reached; this latter expression will be used for convenience when referring to the temperature to which the textile is heated.
  • the heater 18 is rendered effective, the fan 14 is energised and the dampers 8 and 20 are opened.
  • the heater 24 is rendered effective to heat the casing 2 and live steam is injected through injector 4 to bring the humidity within the casing 2 and hence in the drum 1 to a predetermined level at which it is substantially or completely saturated.
  • the atmosphere within the casing 2 is maintained in a substantially or completely saturated condition whilst the temperature is raised by the circulation of the atmosphere through the heater 18. Any initial condensation of water from the atmosphere onto the textile aids the heating of the latter. It will be appreciated that any finishing liquor which is displaced from within the drum 1 by the action of the heated air will be trapped within the filter 12 for subsequent removal.
  • the textile is tumbled throughout the heating step.
  • the heat removed from the atmosphere by the textile is replaced by the heater 18, when however, the tempeature within the drum 1 reaches a predetrmined level as determined by the temperature sensor 21a (this temperature being beneath the fixing temperature), the dampers 6 and 20 are closed and the fan 14 and the heater 18 are rendered ineffective.
  • the heater 24 is, however, maintained in operation so that the temperature within the casing 2, which is now again'isolated from the circulating system, continues to rise, albeit at a lower rate, by transfer from the casing; also the steam injector 4 is operated as necessary to maintain the desired humidity within the casing.
  • the rapid increase in pressure as the water commences to boil is utilized to actuate the pressure sensing means 2119 which is arranged to de-energise the heater 24.
  • the textile in the drum may thus be maintained at the fixing temperature within very precise limits for a sufficient length of time to ensure even fixing of the treatment liquor. If the machine is pressurised, and the casing 2 may well be constructed to withsatnd pressurisation, the boiling point of the liquor will be increased; thus the pressure sensing means 21b may be utilized, in conjunction with the relief valve 2b, to maintain the temperature at any desired level.
  • the action of the finishing liquor on the textile during the fixing step may be modified, if desired, by introducing atomized or vapourised additives through the injector 4.
  • Such additives may, as discussed previously, be utilized to adjust the pH value of the finishing liquor and are applied to the latter by condensation from the atmosphere within the drum.
  • the drum 1 is rotated rapidly in one direction for a predetermined length of time so as to centrifugally extract substantially all of the finishing liquor remaining in the goods.
  • This extracted liquor is discharged to the casing 2 from whence it may be allowed to drain by gravity or may be removed by suitable pump means (not shown).
  • This extraction may be performed either at the fixing temperature or after cooling to a predetermined lower temperature as required and may be followed by a rinsing step.
  • the dampers 6 and 20 are opened and the fan 9 and heaters 1d are again rendered effective. Air is thus drawn into the machine, heated by the heater 18, forced through the textile in the drum l and discharged by way of the duct 10; this rapidly dries the textile in the drum. The dry textile is allowed to cool and may then be removed through the opened door 3.
  • FIGS. 3 and 4 show diagrammatically an alternative machine in which textile in rope form can be finished in an efficacious manner in accordance with the invention.

  • the drum 31 is mounted on trunnions 33a and 33b in the upper part of the casing 30 and the inlet of a circulation and heating system 34 is connected to one of the trunnions 33a which is of tubular form, whilst a drive motor 35 is connected directly to the other of the trunnions 33b.
  • the circulating and heating system 34 includes a fan 36 and a heat exchanger 37 and is connected to discharge heated air withdrawn from the interior of the drum 31 through the hollow trunnion 33a into the top of the casing 30.
  • a conduit 38 (see FIG. 3) at the suction side of fan 36 has branches to atmosphere controlled by dampers 39. Between these, in conduit 38, is a butterfly valve 40 which, when closed and with the dampers 39 open, will allow air to be drawn into the machine by fan 36 from outside and eventually discharged from the machine after passing through the casing 30.
  • An imperforate blanking member 41 of arcuate form is supported by the trunnions 33 and hangs within the drum 31 so that it closes off the perforations in the lower part of the latter.
  • the roller 32 is adjustably supported for movement radially of the drum St on a pair of piston/cylinder units 42 mounted in the casing so that its nips may be adjusted.
  • the roller may be constituted by a tubular element of a resilient impermeable material, e.g., synthetic rubber, which is mounted between circular end checks; the resilient material is inflated by pressurising the interior of the roller so as to ensure an even adjustable nip over the width of the drum 3] in such a case the piston/cylinder units 42 are not required.
  • the roller has a foam forming function when a foam-forming additive is utilised, i.e., it performs mechanical work on textile carried beneath it.
  • the roller could be covered with foamed or sponge material or it could be replaced by a brush.
  • a spray bar 43 extends along one wall of the casing 30 connected to the outlet of a pump 44 which is arranged to spray finishing liquor at a metered rate from a supply vessel 45.
  • the inlet of the pump 44 is also connectible to the interior of the blanking member 41 which is of trough form (see FIG. 4).
  • a baffle 46 is secured within the casing 30* and defines a passage or so-called J-box 46a within the lower part of the casing.
  • a piston/cylinder unit 47 carries a roller 470 which extends transversely of the entrance to the passage 46a. The roller 47a is reciprocated, when the machine is in use, to plate or fold textile as it enters the passage 46:: in the normal direction of operation as shown in the drawing.
