BRIEF DESCRIPTION OF T~E DRAWINGS
One embodiment oE the invention will now be described, by way of example, with reference to the accompanying drawings, of which:-Figure 1 is a diagrammatlc view of apparatus embodyingthe invention;
Figure 2 is a diagrammatic section of a recovery vessel forming a part of the apparatus of Figure l; and Figure 3 is a fragmentary elevation showing a device for preventing the formation of fluff pads at the .~ , . . . .
entry to a treatment cham~er of the apparatus of Figure 1 .
~ ,, Referri~g to ~igure 1 9 it will be seen that the treatment apparatus 9 for example for dyeing, comprises two treatment chambers 1~ through which pass four threads or yarns 2~hereinafter referred to as "yarns") moving in a continuous man~er by means of appropriate drawinK
means (not shown) perpendicularly to the plane of the Figure. ~he two treatme~t chambers 1 are identical and the number of threads or yarns which transverse them can be selected as desired.
Each treatment chamber 1 is constituted by a lower ~`
receptacle (or other part) 3 secured to a framework of the apparatus and is surmounted by a cover (or other part) 4 suspended from a gantry or other support struct-ure 5,the height being adjustable with ~he aid of uprights 6 rigid with the framework. ~hus each treatment chamber i~ co~stituted by two telescopic parts the assembly being closed, although not ln a fluid-tight ma~ner, with respect-~ the ambient.
~ he inlet and outlet pas~ages 7, 8 for the yarns 2 are respectively provided opposite one another in the two lower parts 3 while an atamizer 9, ~ecured to the gantry 5 is mounted at the top of each upper p~rt or cover 4.
At the lower part Or each lower part or receptacle
3 a liquid outlet pipe 5 serves to discharge the latter - ~ ~ .. . .,- . . - -and communicates with a recovery vessel 11 sho~/n in detail in Figure 2. It iæ constituted by a vessel open to the ambient and has internally a grill or other perforate means 12 which supports seveIal layer~ of balls 1~. ~he latter have a small diameter preferably lying between 5 and 10mm and are preferably of glass. It is furthermore desirable that the overall thickness of the layers of balls should be at least 5cm.
The outlet pipe 10 discharges JUSt above the grill 12 after having passed substantially through the layer of balls 13.
At the lower part of the vessel 11 there is disposed a return pipe 14, prov~ded with a control valve 15 and termi~ating at an operating vessel 16 arra~ged adjacent the suction pipe of a pump 17.
A reserve vessel 18 is connected to the operating vessel 16 by a pipe 19 provided with a control valve 20 ~he operating vessel 16 is maintained at a constant level and is supplied from the reserve vessel. Means, (not shown) serve to maIntain the liquid level constant.
The pump 17 comprises a discharge pipe 21 having a pressure ~auge 22 and terminating at one Or the atomizers 9. ~he latter are provided in order to produce atomization of liquid in known manner, and further reference will be made to the atomizers hereinafter.
~ inally, for each chamber a by-pass pipe 23 is provided a~d has a control valve 24. The by-pass provides for communication between the lower part of :
:. .
.. .. .. . . ~.. . ,.. ~ ,.. ..
.
each receptacle ~ of the treatment chambers a~d the pipe 21. With this arrangeme~t, it is po~sible to effect recycling of the treatment liquid directly from the pump to the recovery vessel without passage through the atomizer.
It is necessary to emphasise that the atomizers, of known type, haYe an outlet slot delivering a mist of fine droplets of completely de-aerated liquid. More accurat~ly, the atomization produced by the atomizer does not introduce into the liquid any paras~té air so that the atomized mist is precisely controlled and i8 homogeneous.
The slit nozzle of each atomizer is so disposed that the pla~e of the atomized mi~t is perpendicular to the path of the yarn, and is defined by the inlet and outlet 7 and 8.
It will be noted in this respect, for the given dimensions of the slot of the atomizer, an increase i~
the supply pressure of the liquid enables an increase in the fineness of the droplets of the atomized mist. ~hus for the supply pressure of 1 kg/cm2, the"degree of coverage" of the yarn is of the or~er of 30% whilst it will reach 80% for a pressure of 6kg~cm2. It will be recalled that the "degree of co~erage" is defined as the ratio between the surface of the treated yarn (dye) and the total surface of the yarn~
Similarl~ modification of the dimensions of the slot of the atomizer enables variation in the "density"
U~4(~
of the liquid mist. For a ~iven supply pressure, the smaller the dimensions, the more the mist will be con-centrated.
'rhe operation of the apparatus will be apparent already to the man skilled in the art, but several particular points will now be explained.
The control o~ the height of the gantry 5 enables modification of the density of the region of the atomized liquid traVersed by -the yarn. '~hus, for a given velocity of displacement of the yarn, it is possible to obtain a variation in the number of droplets of liquid encountering the yarn, and as a result, a number of special effects can be achieved particularly if the liquid is a dye. ;
Variations in the special effects may also be provided by means of horizontal displacement of the passages for inlet and outlet of the yarns with respect to the vertical plane passing through the slit of the atomizer. It is also useful to note that variations, possibly periodic, in the velocity of the displacement of the yarn (for example betwee~ 200 and 900 m/minute) in the supply pressure of the atomizer (for example between 1 and 6 kg/cm2) will enable the pro~ision, particularly when they are carefully combined9 of original special effects.
Finally9 it is evident that several apparatus for treatment may be placed in succession along the path'~
of the yarn, each of them enabling the applicatio~ of a : - ,~
dye of predetermined colo~r or any other appropriate treatment.
On the other hand, it is important to maintain the dye at a constant humidity value, in the absence of which the distribution of the dye on the yarn or other elongate me~ber will not be homogeneouq.
~ o this end, the treatment in the substantially closed chamber substantially eliminate~ all air circulation, so that all the atmosphere exi~ting withi~
the installation abo~e the treatment liquid will become saturated very rapidly. ~his is the case for the operating vessel 16 and, it should be understood, as will be apparent, also for the chambsr 1.
With regard to the recovery vessel 11, it ha~ been established that the presence of the layers of balls 13 prevents evaporation which would otherwise occur in the presence o~ fresh air above the free surface of the liquid in thi~ vessel. ~he layers of balls enable however the ;
necessary maintenance of atmospheric pressure in this part of the installation. The ~alve 15 of the return pipe 14 enables emptyinæof the treatment circuit.
An important problem has also been resolved i~ the preferred embodiment. In practice, it may happen, duri~g the treatment of certain yarns, that an accumulation of fluff builds up at the inlet 7. The fluff accumulate~
and forms a pad which absorbs the treatment liquid flowing down the interior walls of the chamber 1. ~he yarn which traverses the pad thus becom~ charged with treatment ~ : . . . ;: ~
_9 liquid before traversing Ghe mist of atomized liquid.
~he products will then have non-acceptable defects.
In order to avoid these disadvantages, the inlets 7 are each defined by a tube extendi~g into the interior of the treatment chamber, the internal extremity bein3 chamfered and provided with a gutter or deflector 7a shown in Figure 3. Liquid trickling down the walls of the chamber will not therefore come into contac-t with the yarn before it has traversed the mist of atomized liquid.
Similar devices are provided for the outlets 8 since the same phenomenon may occur there.
It will be desirable, however, to avoid the formation of fluff which arises by the detachment of fibrils from yarn, for example by electro-static action and/or mechanical action during the traversing of the tubular passages such as provided at the inlet 7.
To this end and as shown in Figure ~, there is arranged upstream of the i~let to the treatment ch~mber, a device enabling the avoidance of the accumulation of fluff. ~ settling chamber 25, surrounds the inlets 7 and comprises simply a closed casing of which the upper surface is constituted by a grid 26. ~he length of the casing 251 in the direction of movement of the ~arn 2, is preferably at least equal to 15 times the diameter of each inlet 7. ~he walls of the casing have a sufficient height, preferably at least equal to ten times the diameter of each inlet 7.
It should be understood, that the wall of the casing 25t opposite the chamber 1, comprises an inlet orifice assembly 27 of which the inter~al diameter is preferably approximately that of each inlet 7c '~he orifice assembly 27 is defined by annular section nozzle~ closed at the side of the settling chamber~ and constituted preferably by two co-axial tubes 28 and 29. At the outside of the settling chamber, the outer tube 28 has a length in excess of that of the inner tube 29. A
distance between the outer ends of the tubes 28 and 29, approximately equal to the diameter of the tube 28t gives good results. ~ pipe 30 discharge~ into the ~mular section space of the nozzle assembly 27 and delivers pressure air under low pressuret approximately 0.5 bar~
During operation, the pressure air removes the fibrils which are not adequately adhered to the yarn which can then really traverse the inlet orifice 27,then the settling chamber 25t and finally the inlet 7 without causing the accumulation of fluff.
Example - The process in accordance with the invention was applied to the impregnation by a dye of four acrylic yarns of high bulk of dernier ("titrage")Nm 2.16. ~he yarns were disposed as groups of two beneath a single atomizer.
Practical conditions were as follows:
- velocity of the yarns; 600 metres per minute;
- atomizer (reference 100/15~ of the company . .

- distance between the yarns of a given group:

- mean distance between the two groups of yarns:60 mm It was found that the "degree of covering" was of the order of 80% in the form of very fine a~d very homogeneous drops. The quantity of liquid used per kilogram of yarn wa~ 120 grams for a "amount of deposit"
