Definitions
- the present invention relates to a dyeing process and achine for washing textile materials capable of realizing large reductions in the amounts of washing fluid used and energy savings, besides reducing the time required to achieve the object of the operation.
- a first known washing process involves carrying out successive operations of completely filling the vessel, e.g. an autoclave, circulating the washing fluid and emptying the vessel until the pollutants present on the aterial are removed for subsequent dilution. This process consumes large quantities of washing fluid and requires a great deal of energy and time .
- Figure 3 diagrammatically shows an apparatus of a known type that works in accordance with the first known process cited above; and Figure 4 diagrammatically shows an apparatus of a known type that works in accordance with the second known process cited above.
- the operation of washing textile materials, loaded onto a material carrier 2 and performed continuously, is carried out with a reduced level 15 of washing fluid inside a vessel 1, which may or may not be pressurized, the discharge fluid always being allowed to reach the maximum possible concentration of pollutants throughout the entire period of application of the process.
- a control system 5 operating as a function, preferably, but not exclusively, of the level of washing fluid m the vessel or autoclave tops the vessel up with an identical quantity of washing fluid through the pipe 22 and the associated washmg-fluid supply valve 8 so that the amount of washing fluid is maintained at the constant desired level.
- valve 18 to introduce compressed air m order to pressurize the vessel 1 and a valve 17 through which the washing fluid present m the vessel 1 can be rapidly and completely discharged and/or the pressu ⁇ zation air can be discharged.
- the process is run continuously until the desired concentration of pollutants m the material is achieved.
- the efficiency of the washing operation can be further improved by fitting a collecting device underneath the material being washed m order to drain off only the most polluted phase of the circulating washing fluid.
- This device consists of a collecting receptacle 4 that makes it possible to evacuate the pollutant-containing fluid coming off the material before it comes into contact with the remaining fluid present at the bottom of the vessel.
- the said collecting receptacle 4 will m any case have an overflow for any circulating fluid m excess of the capacity of evacuation.
- the water can be remtroduced, if the demands of the current operation so require, through the washing valve 8 upstream, along pipe 23, or downstream of the washmg-fluid heating device 6 present inside the vessel 1 along pipe 24 depending on whether it is wished to use heated washing liquid or unheated washing liquid, respectively.
- the continuous process of evacuation and toppmg-up of the washing water which is typical of the invention, permits the optional insertion of a heat recovery unit 14 to recirculate some of the heat energy present m the discharge fluid passing through the discharge pipe 21, and transfer it to the incoming washing fluid through the pipe 25, thus gaining considerable energy savings.
- the discharge line 21 may optionally be fitted with a suitable device 13 for measuring the level of pollutants present m the discharge flow, e.g. pH-meters, redox-meters, opacimeters, or others.
- a suitable device 13 for measuring the level of pollutants present m the discharge flow e.g. pH-meters, redox-meters, opacimeters, or others.
- this measuring device 13 can supply a value relating to the residual level of pollutants present m the material to be treated and therefore can be used advantageously to construct and incorporate a system that will automatically control the duration of the washing operation.
- the washing fluid can be taken directly, via the valve 12, from the water mam 26 through the meter 16 or, via a pump 11, from a special storage and preparatory receptacle 10 which has been supplied with a suitable quantity of fluid, optionally with suitable chemical additives, and is already heated to the necessary temperature for the treatment process.
