  "Method and apparatus for treating wire in the form of a coiled bundle

  
and product so obtained. "

  
The present invention relates generally to the treatment of a

  
wire in the form of a coiled bundle or the like; more particularly, she

  
concerns and essentially relates to a new process

  
improved to process yarn as a bundle wound by

  
a yarn treatment agent to modify the characteristics

  
physical and / or chemical yarn, including the operations

J

  
consisting of introducing the agent into selected portions of the outer surface of the coiled package and then infusing

  
 <EMI ID = 1.1>

  
pressure. In one aspect of the present invention, the process involves treating the yarn in the form of a coiled bundle with one or more dyes or like dyestuffs to create.

  
a repeating succession of colors in a reproducible manner.

  
In another embodiment of the method according to the invention, a dye or material acceptance modifier

  
coloring agent, for example a resist or the like, is infused

  
in one end or in both ends of a coiled bundle

  
fillet a heated fluid, for example water vapor, is then introduced under pressure at a temperature and for a time sufficient to force the dye acceptance modifier

  
or dye to partially penetrate into the coiled package and

  
come into contact with individual filaments, strands or strands

  
yarn or fiber and can fix the acceptance modifier

  
dye or coloring matter if necessary. Thread

  
thus treated can then be dyed directly by conventional techniques or else shaped with other strands of treated yarns or

  
untreated to form a fabric or cloth, after which the fabric

  
or the fabric is dyed to create a pattern or design

  
pleasant of several tones, tints or shades.

  
In another embodiment of the invention, a plurality

  
of coloring or dyeing materials is introduced at the ends

  
the coiled package and a heated fluid, such as water vapor,

  
is then introduced for a time long enough to force

  
the dyes or coloring materials to penetrate at least partially into the wound pack.

  
Further, the present invention is directed to an apparatus or device by which the aforesaid method can be carried out and practiced to treat yarn in the form of a coiled bundle either with dye or colorant acceptance modifiers or with dye acceptance modifiers. dyes or dyes or by other treating agents to obtain the desired characteristics. Finally, the invention relates to, as new industrial products, the wound bundles of treated wire and similar articles obtained by the aforementioned process as well as the various applications and uses resulting from the implementation of said process and / or of said apparatus and its systems. ,

  
 <EMI ID = 2.1>

  
provided with such improved apparatus.

  
In general, attractive or pleasing color effects, which can be achieved in a fabric or fabric by the use of what is commonly referred to as "space dyeing", have been recognized in the art. In addition, methods and apparatus

  
have been developed or perfected over the years to achieve such effects by selectively dyeing portions of a coiled bundle of yarn. As used herein, the term "yarn in the form of a coiled bundle" is intended to denote and means a mass of yarn which is wound on a tube, on a cone, on a bobbin or spool or on other such carriers. classic. These processes fall into two broad categories. One of these categories involves the use of needles to inject the dye or coloring material into selective portions of the coiled bundle of yarn. A typical example of this mode of treatment is the process disclosed in the US patent? 3,547,575.

   Such methods of the prior art are time consuming and present problems relating to the reproducibility and uniformity of the dyeing. Also by using fine or low denier yarns, the needles usually tear, tear or break the fibers of the yarn causing obvious problems when

  
the yarn is then shaped into a fabric by weaving or knitting.

  
The second broad category of prior art processes is typically represented by U.S. Patent No. [deg.] 3,145,398.

  
according to which the dye is forcibly passed radially

  
through selective portions of a coiled bundle of wire by the use of centrifugal force. The centrifugal force process has the inherent disadvantage of deforming the coiled bundle of wire during operation.

  
It should be noted in passing that pressure per se has been used in the prior art to dye yarn in the form of a wound bundle. However in such prior art processes as disclosed for example in US patents

  
N [deg.] 3,878,575 and 1,841,024, the entire wound packet was dyed evenly to the same shade, shade or color.

  
Space dyeing has also been accomplished by the use of resist agents which modify or change the locations of dye or coloring matter in the yarn to force them out. receptive for certain kinds of dyes. See for example

  
 <EMI ID = 3.1>

  
fiber reactive, which can be applied to specified fibers to create a local reservation against dyeing by anionic or acid dyes. See also the application of resist agents by the roll printing process to form a pattern or pattern of resist and non-resist sections as disclosed in U.S. Patent No. [deg.] 3,700,402 However, roll printing of fine, low denier yarns is

  
both impractical and commercially unattractive because of

  
of high ccftt.

  
In summary, each of the methods of the prior art, to achieve a varied, diverse, variegated, variegated, dyeing effect,

  
&#65533;

  
diapré, variegated or. versicolor on the yarn, has one or more undesirable characteristics, which previously limited the commercial acceptance of these processes. The need for a new technique, which creates the desired pleasing multicolor or shadow effect without undesirable characteristics, is evident.

  
In summary, the present invention is advocated, in part,

  
based on the finding that a yarn treatment agent can

  
be selectively and reproducibly infused into a mass

  
wire in the form of a bundle wound by means of a fluid at high temperature and under pressure. Heated fluid under pressure

  
forces the yarn treatment agent to penetrate both the

  
bundle wound and in individual filaments, strands or strands

  
wire or. fibers to a predetermined depth and, if

  
so desired, to fully penetrate the coiled package. This unique and non-obvious solution to the long-standing problem in the field

  
of thread dyeing. provides a simple, practical and commercially attractive method of achieving the goals of dyeing in space without any of the drawbacks of the prior art methods.

  
The process according to the present invention involves the introduction of a yarn treatment agent, for example a dye acceptance modifier or a similar dye or coloring material into selected portions of the outer surface of a. coiled bundle of wire, followed by exposing such portions

  
surface to a fluid at high temperature and pressure. The heated fluid passes through the coiled bundle of yarn and carries or carries the yarn treatment agent with it. In this way,

  
a controlled penetration of the yarn treatment agent is achieved. Taking for example the process in which a dye acceptance modifier is infused or introduced at only one end of the wound pack, the result of these process operations produces a coiled bundle of yarn having three different sections which have relatively varying amounts of ac-

  
 <EMI ID = 4.1>

  
which the dye acceptance modifier has been infused,

  
 <EMI ID = 5.1> <EMI ID = 6.1> the adjoining section at the opposite end of the coiled bundle of wire,

  
 <EMI ID = 7.1>

  
tion of dye present. In the middle section, there is a concentration or proportion of modifier which is intermediate between those of the two extreme sections. It can be seen that as the yarn is unwound from the coiled bundle thus treated, there will be repeated successions of continuous lengths of yarn which are fully processed, intermediate processed and not processed by the dye acceptance modifier. In the event that a reserve agent

  
classic is used as a dye acceptance modifier,

  
it is thus produced, by the present invention, a mass of wire

  
having repeated successions of contiguous sections which, after dyeing, will result in high dye acceptance,

  
moderate dye acceptance and no acceptance

  
of dye.

  
In a preferred embodiment of the present invention, a coiled bundle of yarn can be treated with one or more dyes or coloring materials thereby producing a yarn which has contiguous sections of differently colored lengths.

  
For example, if a first dye or coloring matter is introduced at one end of the wound pack and if a different colored dye is introduced at the other end of the wound pack, yarn having lengths of both colors in addition to one mixture of the two colors will be produced. Further by a method discussed in detail below, it is possible to introduce two or one more

  
(large number of dyes or dyes on each end of the wound pack thereby creating a dyed yarn which has continuous lengths of at least four colors and additional lengths of mixtures of the colors or dyes used.

  
As used herein, the term "end" of a coiled bundle of yarn is intended to denote a face of the coiled bundle of yarn which is perpendicular to the longitudinal axis of the coiled wire. Using this terminology, a coiled bundle of wire has two ends and a circumferential surface, the latter being cylindrical or conical in shape, for example, depending on the coiling or coiling method employed. As used here, the expression

  
"Coiled bundle yarn" is intended to denote and mean a mass of yarn which is coiled on a tube, on a cone, on a bobbin or spool or on other such conventional carriers. As used herein, the terms "fiber" and "yarn" have the same meaning as those normally used in the art, i.e. "fiber" denotes an individual filament of natural or synthetic material and the word "yarn" "refers to a bundle, group or bundle of several fibers gathered and normally twisted together.

  
 <EMI ID = 8.1>

  
it is possible to process a large mass of yarn in compact form, i.e. as a coiled bundle of yarn rather than

  
in the form of a skein, chain or knitted sock. The particular type of coiled bundle employed in the present invention "

  
is not a critical factor. Thus, the yarn can be wound on a cone, on a tube, on a bobbin or spool or wound up to form a coiled bundle in any similar manner. The repeated pattern or configuration of the wire will obviously vary depending on the method used to wind the wire. For example, if the wire is wound at a constant speed and in constant motion

  
reciprocating, i.e. wound on a drum and if the wound bundle is processed from the ends, the repeated sections of yarn which are fully processed, partially processed

  
 <EMI ID = 9.1>

  
 <EMI ID = 10.1>

  
the most desirable effect and distribution or distribution of colorants.

  
By the method of carrying out the method briefly described above

  
using a dye acceptance modifier, one packet

  
coiled wire is obtained in accordance with the present invention, which has the latent characteristics of a coiled bundle of wire

  
dyed in space, However, from a commercial point of view, the

  
method according to the present invention is very advantageous in that a mass or reserve available or in stock of coiled bundles of

  
 <EMI ID = 11.1>

  
thus substantially the stock or inventory that must be maintained

  
at the store. In developing this stage further, a knitter or

  
a weaver is made capable of making fabric made

  
from such wound bundles of treated yarn in stock or inventory available before dyeing thereby substantially reducing the stock

  
or available inventory of woven or knitted fabric which must be kept in store by a textile mill, factory or spinning mill, for example.

  
As soon as it is desired to make a fabric of a certain color, the fabric thus prepared is then dyed by conventional methods.

  
to create the pleasant or attractive multi-colored effects commonly associated with space-dyed yarns.

  
Direct dyeing of the coiled package, using another

  
method of carrying out the process in which one or more dyes

  
or coloring matters are infused into different surfaces,

  
also offers a lot of advantages. Color effects, which cannot be obtained otherwise, are achieved in a simple way with maximum use of dye or dye and

  
fi <EMI ID = 12.1>

  
minimal energy expenditure.

  
 <EMI ID = 13.1>

  
 <EMI ID = 14.1>

  
 <EMI ID = 15.1>

  
wire treatment is used followed by a wire treatment

  
 <EMI ID = 16.1>

  
repeated successions are much the same. When more than one dye or coloring material is employed in accordance with the present invention, then the repeated sequences of colors in the spooled bundle of yarn are also reproducible.

  
A further aspect of the present invention is the manner in which spooled bundles of yarn, treated as mentioned above, can be shaped by knitting or weaving by.

  
 <EMI ID = 17.1>

  
one or more filaments, strands or strands of yarn, treated in accordance with the present invention, may be woven or knitted together with one or more filaments, strands or strands of yarn

  
untreated. In this way, completely new and pleasant effects can be achieved. Such a fabric can also then be dyed in the room to produce multicolored, diverse, variegated or variegated effects. When the wire heating agent is an agent

  
reservation, it is possible to create an attractive appearance using some type of dye or. of dye which selectively colors only the untreated strands of yarn and another type of dye which selectively colors the fully or partially reserved portions of the strands treated in accordance with the present invention.

  
 <EMI ID = 18.1>

  
create new and unusual color effects. By mixing natural and synthetic materials, different types of synthetic material give new and unusual results.

  
The process according to the present invention can also be employed with treating agents which introduce dye locations into the fibers of a yarn in a selective manner. So by

  
 <EMI ID = 19.1>

  
feel invention, treating agents, which create locations

  
dye in polyester, can be used to achieve

  
the same type of configuration or design repeated throughout

  
of wire forming the coiled bundle of wire.

  
In addition to the above, wire in the form of a coiled bundle

  
can be treated with other agents such as lubricants

  
of yarn to create certain desired effects. In principle, the process according to the present invention can be used to impregnate

  
a coiled bundle of yarn with any conventional or known yarn treatment agent in a predetermined manner.

  
There has also been disclosed, as part of this invention, an apparatus which is particularly suitable for carrying out the method described herein. In a preferred embodiment, the apparatus comprises means for dosing or measuring pre-selected amounts of yarn treatment agent, for example a dye or dye acceptance modifier, means for introducing or infuse such a metered amount into selected portions of the end or ends of a coiled bundle of wire, for example by means of a perforated plate and means for exposing the coiled bundle of wire to a fluid heated to high temperatures. high pressures to infuse the textile treatment agent into the interior of the spooled bundle of yarn. Those who are competent in

also for treating coiled packages of yarn with a wide variety of textile treatment agents such as lubricants for example.

  
The invention will be better understood and other aims, characteristics, details and advantages thereof will emerge more clearly on reading the explanatory description which will follow in

   and
- Figure 6 is a partial schematic illustration showing an alternative embodiment of one of the collectors shown in Figure 1.

  
To help a better understanding of the method according to the present invention, we will consider Figures 5a, 5b and 5c. Figure 5a schematically shows a coiled bundle of yarn 114 being processed in accordance with one aspect of the process according to the present invention. A certain amount of dye acceptance modifier is infused into both ends of the wound pack 114.

  
This is schematically illustrated by arrows 121 at the upper end and by arrows 123 at the lower end of the

  
coil pack 114. The modifier can be applied as

  
paste or viscous liquid or, alternatively, may be introduced in liquid form under pressure using the apparatus disclosed herein.

  
After the dye acceptance modifier has been infused into the ends of the coiled bundle of yarn, a fluid

  
heated under pressure, such as water vapor, is introduced

  
at the ends of the coiled packet 114. Thus, arrows 121 and 123 also schematically indicate the flow pattern of the heated fluid or steam. Certain means, such as a perforated plate shown in Figure 2 of the accompanying drawings,

  
are, of course, desirably employed in order to properly contain the heated fluid under pressure. The action of the heated fluid, moving through the coiled bundle 114, carries with it,

  
the dye acceptance modifier.

  
Following the treatment according to the present invention,

  
a cylindrical section 125, shown in Figure 5a as

  
 <EMI ID = 22.1>

  
of dye. Section 129, in the approximate middle of coiled bundle 114, will be found to be substantially untreated by the dye acceptance modifier and intermediate sections.
127 will appear to have been partially processed by the dye acceptance modifier.

  
Figure 5c schematically represents the characteristics <EMI ID = 23.1> that has been described above. There will thus be sections or. segments of yarn 125a which are fully processed by the dye acceptance modifier, sections or segments 127a which are

  
are partially processed and sections or segments 129a which

  
are substantially untreated. Each of these sections or segments

  
125a, 127a and 129a will have different dye receptivity

  
as a result of the differential treatment according to the method

  
according to invention debt.

  
If the coil package 114 is wound with a constant speed

  
and with a constant back-and-forth movement, i.e. coiled

  
 <EMI ID = 24.1>

  
repeated sequences of sections 125a, 127a and 129a will be sensitive

  
equally, varying only slightly from beginning to end. The relative or proportional variation, between sections <1> <2> 5a, <1> <2> 7a and 129a, is a function of the amount of dye acceptance modifier used and the length of the period:
time or duration as well as pressure and temperature

  
of the heated fluid that is employed. The selection of these parameters

  
is well within the skill or ability of someone who is familiar with this technique because of the examples set out below.

  
Figure 5b schematically illustrates a coiled bundle of wire

  
 <EMI ID = 25.1>

  
of dye at the top end only of the coil package

  
as indicated by the arrows 121. In such an embodiment, there are only three distinct sections of coiled bundle of yarn which have different treatments: section 125 which will be treated substantially entirely, section 129 which will be substantially untreated. processed and the intermediate section 127 which will be partially processed. ,

  
In an illustrative embodiment employing the method of the present invention, nylon 66 is treated using, as a dye acceptance modifier, one of the conventional reservation agent chemicals such as the product known as “Verona Resist” manufactured by the American company known as the Verona Chemical Company or else the product known under the name of “Sandoz Space R” manufactured by the American company known as Sandoz Chemical Company. In the event that the agent

  
reserve, chosen for use in this method, must be fixed, the heated fluid, for example water vapor, accomplishes this purpose.

  
The simplification of the method according to the present invention enables more than one yarn treatment to be accomplished during a process.

  
 <EMI ID = 26.1>

  
or dyes or a dye acceptance modifier, the yarn can be treated with a lubricant and thus avoid a separate subsequent operation. As is well known, lubricating the yarn is a virtual necessity before knitting and usually involves rewinding the wound pack.

  
In accordance with the present invention, the yarn thus treated can then be constructed or produced by weaving, knitting or the like to form a fabric or fabric which can then be dyed or dyed.

  
 <EMI ID = 27.1>

  
Completely from the examples given below, one or more treated or untreated strands can be used to form the fabric and thereby create a wide range of color combinations or colors in the finished fabric. In addition, different combinations of dyes or dyes can be employed to achieve different designs or color configurations. Referring to Fig. 5c, it will be appreciated that while the dye acceptance modifier is a conventional reservation agent which is resistant to acid dyes or dyes and when the yarn is subsequently dyed with an acid dye or dye, sections 125a

  
will not be dyed, sections 127a will be moderately colored, and sections <1> 29a will exhibit a deep or pronounced or dark color tone or shade.

  
The apparatus according to the present invention, for carrying out the methods described herein, will now be described.

  
Referring now more particularly to the embodiment of the apparatus according to the invention chosen here by way of illustration, it can be seen in FIG. 1 that there is a coiled packet receiving chamber 10 having a base or lower part

  
<1> <1> which supports a lower manifold 12. Support posts or support struts 14 support a top plate 15 and the top plate <1> 5 has a pneumatic cylinder cylinder 16

  
on the latter, the piston rod 18 of which passes through the upper plate

  
15. At the lower end of the piston rod 18, there is an upper manifold 19. It will therefore be understood that the arrangement is such that, when the piston rod 18 is protruding out of the pneumatic cylinder cylinder. 16 or returned therein, the upper manifold 19 will rise or fall.

  
Each of the collectors 12 and 19 respectively carries perforated plates 20 and <2> <1>. Plates 20 and 21 cover cavities

  
22 and 24- respectively in the collectors 12 and 19 and the plates
20 and <2> <1> are preferably interchangeable to allow the use of other shapes and structures of perforated plates.

  
In the embodiment shown in the accompanying drawings, the perforated plates 20 and 21 are the conduits through which the treating agent ect introduces to the coiled bundle of yarn.

  
In addition, the outer surface of the plates forms an airtight seal or pressure-tight seal with the periphery of the ends of the coiled bundle being processed, so that the yarn treatment agent or steam no water

  
6 <EMI ID = 28.1>

  
does not escape into the atmosphere but rather passes into the coiled bundle. It should be understood that the circumferential portion of the plates 20 and 21 could be extended to form a sleeve which would completely enclose or surround the coiled bundle of wire during operation of the apparatus. A further variant embodiment is that a plate, having a plurality of open spaces rather than holes, could <EMI ID = 29.1>

  
so that it forms a suitable seal with the ends of the coiled bundle of wire.

  
A tube 25 is connected, at one of its ends by means of inlet branch tubes 26 and 28, to the lower manifold 12 and is in communication with the cavity 22. the tube
25 is connected by its other end to the control means for adjusting the lower manifold which is generally indicated by

  
29 and will be described in greater detail in a later part of this description.

  
A flexible pipe 32 is connected at one of its ends

  
via inlet branch tubes 30 and 31,

  
to the upper manifold 19 and is in communication with the cavity

  
24. The flexible pipe 32 is connected by its other end to the means
34 control for adjusting the upper manifold, which will be

  
described in greater detail in a later part of this description.

  
From the foregoing description, those skilled in the art will now understand that a coiled bundle of textile yarn of any conventional shape can be placed on the lower perforated plate 20. The pneumatic cylinder cylinder 16 can be actuated so that the piston rod 18 comes out in extension

  
 <EMI ID = 30.1>

  
upper plate 21 comes into contact with the upper surface of the coiled bundle of wire. Perforations in perforated plates
20 and 21 are located so that they come into contact with

  
the wire which is on the coiled bundle of wire and does not come into contact with the tube or other coil core material on which the wire is wound. Means are provided for introducing a desired yarn treatment agent, such as a dye or coloring material or a dye acceptance modifier,

  
through tubes 25 and 32, so that the chemical enters cavities 22 and 24 through the perforations

  
in the perforated plates 20 and 21 and comes into contact with the wire of the coiled bundle of wire.

  
According to another embodiment of the method according to. In the present invention, a predetermined amount of yarn treatment agent is infused into at least one surface of the coiled bundle of yarn. The apparatus, shown in Fig. 1, is one in which infusion can take place in both ends of the coiled bundle of wire.

  
The apparatus, capable of accomplishing this aspect of the present invention, therefore comprises a first metering or metering means 35 for metering the treating agent which is to be infused into.

  
the lower surface of the coiled bundle of wire and a second measuring or metering means 36 for metering the treating agent which is to be infused into the upper surface of the coiled bundle of wire.

  
In more detail, the first metering means 35 comprises a container 38 having a tube 39 in communication with the container.
38 and extending from the lower bottom of the container 38, the tube
39 being connected to the adjustment control means 29. At the top of the container 38, there is a tube 40 which is connected to a valve or the like 41. In the container 38, there is a float 42; the float
42 is intended to float on the surface of the material which is introduced into the vessel 38 through the piping 39.

  
As envisioned herein, the walls of container 38 are transparent and there is a light source 44 on one side of container 38 and a photocell 45 on the side opposite Au. receptacle 38 and located to receive light from the source

  
 <EMI ID = 31.1>

  
45 to be excited or de-excited depending on whether the photoelectric cell
45 receives or does not receive light from the light source 44. It can thus be seen that, when the float 44 floats

  
on top of the material which is introduced into the container 38 and when the float 42 rises to a point which is between the light source 44 and the photocell 45,

  
the light, coming from the light source 44 and reaching the photocell 45, will be interrupted, so that the relay
46 will be de-energized.

  
Relay46 is connected, through a cable or

  
wire 48, to a solenoid 49, the solenoid 49 being arranged to actuate a valve 50. the - line 51 leads from the valve 50 to a storage or containment tank or to.

  
another source of material or. agent capable of serving as a modifier, or a combination thereof, under pressure, so that when valve 50 is opened material will flow

  
through line 51, through valve 50 and then through

  
a check or non-return valve 52 and up to the piping
39 which will allow material to pass to enter the container 38. As the material fills the container 38, the float 42 will float on top of the material until the float 42 reaches the level of the photoelectric cell 45 and of its light source 44. When the float
42 blocks, that is to say occult or. intercepts the light source

  
44, relay 46 will be de-energized and this in turn de-energizes

  
solenoid 49 and will force valve 50 to close. When the valve

  
If 50 closes, it is easily seen that the flow of material from the storage tank to the container 38 will be terminated.

  
As the material rises in the container 38, the air in the container 38 must be moved; therefore, the valve 41 is positioned as indicated thereby allowing

  
air to escape from container 38 through line 40 and through valve 41 to vent port 54.

  
After the desired amount of material has been introduced into vessel 38, valve 41 is moved so that a source of compressed air or other suitable inert gas, which is available on line 55, is connected to it. through valve 41 to line 40, so that compressed air is supplied into container 38 above the material. Also at this point, a valve
56 is opened by energizing a solenoid 58, so that material can flow, leaving the container 38 under the pressure of compressed air, through the tube 39 and then through the branch line 59, to through valve 56, through check valve 60 and enter tube 25 from where material will pass through inlet tubes 26 and 28 and enter the cavity
22 from the lower manifold 12 then into the coiled bundle of wire.

  
The second metering or measuring means 36 is similar to the first measuring or measuring means 35, so that the metering means 36 will not be described in detail. It will be noted that the metering means 36 comprises a container 61 comprising a lower pipe 62

  
and an upper pipe 64 which is connected to the pipe 40. A light source 65 is provided for a photoelectric cell.
66, the photocell 66 actuating a relay 68. the relay
68 controls a solenoid 69 to actuate a valve 70. the valve
70 connects the source of material through line 71, through check valve 72, then through line 62, with the interior of vessel 61 to force float 74 to rise to block or intercept the beam of light from light source 65.

  
When material is forced out or forced out of container 61 through tubing 62, a solenoid 75 is energized to open a valve 76 to allow material to pass through branch pipe 78, through valve 76 and on. through a non-return valve 79 to enter the pipe 32 then into the pipes 30 and 31 and then into the cavity 24 to

  
 <EMI ID = 32.1>

  
After the material has been distributed to the ends of the coiled bundle of wire, a heated fluid under pressure is similarly delivered and distributed to contact the ends.

  
 <EMI ID = 33.1>

  
dyeing, dyeing or coloring matter or treating agent in the interior of the coiled package and for fixing the agent if necessary.

  
In the examples presented below, the heated fluid, used according to the process according to the present invention, is

  
water vapor. For the sake of simplicity of the discussion, the following description will be made in terms of using water vapor as the heated fluid, but it should be understood that other fluids may be employed, provided that the yarn treatment agent particular does not require the presence of moisture or water vapor. When water vapor or heated fluid passes

  
through valve 82 it continues through branch line 81 to tube 25 for injection into the lower end of the coiled bundle of wire through lower manifold 12. Similarly, water vapor will pass from there. the

  
 <EMI ID = 34.1>

  
through valve 86 which is actuated by a solenoid 88. When water vapor passes through valve 86, it continues to flow

through branch pipe 85 to flexible pipe 82

  
to be injected into the top of the coiled bundle of wire through the upper manifold 19.

  
When water vapor enters the coiled bundle of wire, it initially condenses and forms moisture. As and

  
As more water vapor enters the coiled bundle, the amount of water inside the coiled bundle may change. Depending on the pressure and temperature of the water vapor and the duration of the treatment, a drying operation may be useful in order to remove any excess moisture.

  
Turning now to the control system for the apparatus described above, it will be seen that there is a timer 86 which is electrically operated and is started or turned on.

  
by means of a push-button 91. When the button 91 is pressed to close the circuit, the timer 90 is started:

  
 <EMI ID = 35.1>

  
to the connecting cable or wire. 92 to energize the solenoid 94- and move a valve 95 to allow compressed air to flow from the supply line 96 through the valve 95 and to the piping 98 which supplies compressed air into the rear of the pneumatic ram cylinder 16 to force the piston rod 18 to protrude out. We will remember that when

  
the piston rod is protruding out, the upper manifold 19 will be lowered to come into contact with the coiled bundle of yarn to prepare for the delivery and distribution of material in the coiled bundle of yarn; however, if the containers 38 and 61 are not filled with material to the predetermined level, the process will not proceed because the amount of material

  
is not present in the desired amount.

  
 <EMI ID = 36.1>

  
reciprocal servoing can be provided to ensure that

  
i the material is not delivered and dispensed until the predetermined quantity has been detected or ascertained by the measurement, here is shown a simple holding circuit in which the timer member 90 continues to operate only if the electrical switches 46-1 and 68-1 are closed. We will understand

  
that the electrical switch 46-1 is a relay contact which

  
is actuated in relay 46 and switch 68-1 is a relay contact which is actuated by relay 68. It can therefore be seen that when relay S46 is energized it is an indication that light coming from the light source 44 is in contact

  
with photoelectric cell 45 to energize relay 46 and

  
the solenoid 49 is energized to open the valve 50 and allow

  
material to flow into the container 38.

  
As the relay 46 is energized under these conditions, the electrical switch 46-1 will be open; however, when material rises in container 38 enough to allow float 42 to block or intercept the beam of light from the source

  
 <EMI ID = 37.1>

  
electrical switch 46-1 to return to its normal closed position. The same is valid for the electrical switch 68-1 and, as the electrical switches 46-1 and 68-1 are connected

  
 <EMI ID = 38.1>

  
as a hold circuit for the timer 90 and continue the operation.

  
 <EMI ID = 39.1>

  
lowered into abutment against the wound bundle of wire, the containers
38 and 61 are filled to their predetermined levels, the timer 90 will apply an electrical voltage to the cable or wire

  
 <EMI ID = 40.1>

  
41 to connect the compressed air supply source through line 55 and through valve 41 to line 40. Likewise, timer 90 will apply an electrical voltage to connector wire 101 and connector wire 102 to respectively energize the solenoids 58 and 75 thereby respectively opening the valves
56 and 76, so that material will flow from the containers
38 and 61 through tubes 39 and 62, through valves 56 and

  
76 up to tubes 25 and 32.

  
After a period of time of a predetermined length, the timer will remove the electrical voltage from the connecting wires 99, 101 and 102, so that: the valve 41 will move to exhaust the containers 38 and 61 at through tube 40 and through vent tubing 54; the solenoid 58

  
will be de-energized to close valve 56 and solenoid 75 will be de-energized to close valve 76. At this time, timer 90 will apply electrical voltage to the connecting wires.
104 and 105 to respectively energize the solenoids 84 and 88 to respectively open the valves 82 and 86 thereby allowing

  
 <EMI ID = 41.1>

  
 <EMI ID = 42.1>

  
82 and 86 then, from there, enter tubes 25 and 32.

  
Note that as soon as the valves 56 and 76 are closed, the valve 41 is moved to exhaust the containers 38 and 61 and the material will have been removed from the containers so that the floats 42 and 74 are located at the bottom. bottom of the receptacles to allow the light sources 44 and 65 to direct their light towards the photocells 45 and 66, so that the relays 48 and 68 are energized and energize the solenoids 49

  
 <EMI ID = 43.1>

  
will be re-filled into containers 38 and 61. Towards the end of the processing cycle of a single wound bundle of yarn, containers 38 and 61 will be re-filled to the predetermined level with a metered amount of fresh or new material. , of

  
if so that the next wound bundle of yarn can be processed without delay.

  
For a variation in the processing scheme of a coiled bundle of wire, consider Figure 3 of the drawings which shows a modified embodiment of the upper manifold.

  
 <EMI ID = 44.1>

  
division 105, so that the cavity is divided into two separate and distinct cavities 106 and 108. From the cavity 106 leaves a

  
flexible pipe 32a and the cavity 108 leaves a flexible pipe 32b.

  
In each of the pipes 32a and 32b, there is a valve indicated in

  
109 and 110. With this arrangement, we see that we can pass

  
of the material through the common piping 111, through the two valves 109 and 110, through the tubes 32a and 32b and into

  
cavities 106 and 108. As each of the pipes 32a and 32b can be controlled separately by means of its own valve 109 or 110, it can be seen

  
as matter, flowing by entering each of the cavities

  
106 and 108, can be separately controlled or set to make

  
vary the amount of material that is delivered and dispensed to

  
individual portions of the coiled bundle of wire. Likewise, we

  
passes water vapor through the same pipes,

  
so that one can vary the quantity of water vapor which

  
is delivered and distributed to separable portions of the package

  
coiled wire.

  
In another embodiment shown in Figure 6, tubes 32a and 32b are connected to separate sources of treating agents, not shown, so that two treating agents

  
different yarns, for example two dyes or colored materials

  
different rents, can be introduced into the upper end of the wound bundle of thread 114.

  
Figure 3 also shows another modification of the apparatus shown in Figure 1. In Fig. 3, the perforated plate 21 'is not in contact with the surface or the upper end of the coiled bundle of thread 114. With this arrangement, a

  
treating agent, such as a thread lubricant, will be projected and sprayed non-selectively against the upper end

  
of the coiled bundle of wire 114. To prevent splashing or. effusion of chemical when delivered and dispensed onto the coiled bundle of wire 114, there is provided a skirt or the like 115 carried by the upper manifold 19 'and extending downward to cover the top of the bundle

  
spool of thread 114.

  
Another modification, to selectively treat portions of a coiled bundle of yarn, is shown in Figure 4 of the drawings. We see here that the 19 "manifold includes a perforated plate

  
 <EMI ID = 45.1>

  
flaring out into a substantially conical element 11 6. Well

  
that the shape of the element 116 can vary at will, its aim is to constitute an enclosure in communication with a perforation,

  
so that material can pass through the perforation
115 and enter enclosure 116 to process a discrete portion or isolated point on the coiled bundle of wire.

  
Keeping in mind the description of the foregoing embodiments of the apparatus and some discussion of its operation, the handling of spooled bundles of yarn by it will now be understandable to those skilled in the art. Below are several examples of dye acceptance modifier and lubricant treatment, which are intended to illustrate one embodiment of the present invention. dyeing chemicals. and reservation involved are well known in the art. It should of course be understood that the examples are intended to be il-

  
 <EMI ID = 46.1> performed.

  
EXAMPLE 1

  
A coiled package of 1.14 kg of $ 1.14. 100/26/1 nylon 66 drum wound is used. (The designation "100/26/1" means that the yarn has a fineness count of 100 denier, consists of
26 filaments and that the yarn is not twisted or stranded.) The apparatus described above has such a coiled bundle placed therein and the steam portion of the apparatus is used to spray water. water vapor through a number of such coiled packages to heat the apparatus. The water vapor is maintained

  
 <EMI ID = 47.1>

  
boiler between 6.21 and 6.89 bar, After the appliance has heated up, a coiled package of 1.134 kg to be treated is inserted into

  
 <EMI ID = 48.1>

  
ment under the name Sandoz Space R and available from the American company known as Sandoz Chemical Company, in an amount by weight

  
 <EMI ID = 49.1>

  
in a volume ratio of approximately 7.5 to 1. To this mixture is added trisodium phosphate to adjust the pH of the mixture.

  
to a value between 8 and 10. This mixture is stored in a containment tank which is the source of the material

  
to be introduced through valves 60 and 70. The containment tank maintains the reservation agent at room temperature. The reservation agent is kept in solution by whipping or shaking. The resulting mixture is pumped from the containment tank and then infused into the coiled bundle of wire.

  
while being followed by. water vapor at a temperature of approximately 149 [deg.] C and at a pressure between 6.21 and 6.89 bar. The water vapor is maintained for approximately one and a half minutes.

  
Those who. are skilled in the art will understand that

  
6 reserve chemicals, used in the treatment of. nylon can have a relatively high viscosity which is lowered by heating. Such reserve substances are also fixed or fixed in the wire by the use of high temperatures.

  
In the procedure of Example 1, when the reserve chemical is delivered and dispensed on the coiled packet

  
wire for infusion, there may be some penetration

  
material in the coiled bundle due to the pressure of the compressed air acting on the chemical and the fact that the product

  
 <EMI ID = 50.1>

  
significant chemical penetration either into the coiled bundle of the yarn or into the individual fibers of the yarn. The water vapor, immediately following the infusion, lowers the viscosity of the reserving agent by forcing it to penetrate both the wound bundle of yarn and the individual fibers of the yarn. In addition, the water vapor forces the reservation chemical to set or bind to the wire.

  
A dye or coloring matter bath is prepared in which a yellow acid dye, a blue dye known as Sevron ACN

  
 <EMI ID = 51.1>

  
bath together with a retardant such as Sandoz CCm in a conventional manner. The yellow acid dye will stain only those portions of the nylon that are untreated or partially treated;

  
 <EMI ID = 52.1>

  
are cationic and will dye the yarn only in areas that have been partially or completely set aside. The bath is brought in &#65533;. boiling, after which yarn, having a repeating length as shown in Fig. 5c, is dyed and processed in a conventional manner. The result is yarn having sections 125a colored blue, sections 127a colored light blue and sections 129a colored yellow.

  
EXAMPLE 2

  
The apparatus according to the present invention is heated in the manner described in conjunction with Example 1 and a coiled bundle of

  
 <EMI ID = 53.1>

  
treatment. Sandoz Space R reservation agent, in an amount by weight of 2% to 3.5% of the weight of the wound packet, is mixed with a lubricant such as ordinary winding oil <EMI ID = 54.1>

  
The mixture is added water to obtain a volume ratio of water and lubricant to volume ratio of reserving agent which is about 8.5 to 1. The treatment chamber is surrounded by a cylindrical enclosure or ferrule which will allow water vapor to be slowly released or released from the coiled bundle of wire but will maintain water vapor in contact with its sides or faces. Water vapor, at a temperature of approximately

  
 <EMI ID = 55.1>

  
bar, is then applied as indicated above for a period of one and a half minutes.

  
In this example, trisodium phosphate is omitted since trisodium phosphate can react with certain reserving agents to form byproducts comprising chlorine acid.

  
 <EMI ID = 56.1>

  
corrosion of knitting or weaving machines or looms in which the yarn is subsequently used. Thus, the elimination of trisodium phosphate avoids the risk of corrosion. However, trisodium phosphate aids or contributes to fixation, so that in its absence it is necessary to remove the wire in an enclosed steam chamber so that water vapor is present at the outside of the package wound to ensure

  
 <EMI ID = 57.1>

  
water vapor is indicated when the rate of binding of the reservation agent is lower than the rate of diffusion of the agent

  
reservation through the coiled bundle of wire. If the coil pack 'is kept, in this example, in the apparatus, the agent

  
reservation will tend to diffuse outward or outward towards the sides or faces of the coiled bundle thus creating a type of reservation pattern or design different from

  
whichever is desired. Processing the coiled bundle in a room

  
steam, the booking agent is forced to settle without diffusion. Maintaining the coiled package in a steam chamber for approximately 30 minutes at relatively low temperature and pressure is satisfactory to achieve the desired result.

  
The addition of the lubricant is beneficial in that it avoids an additional processing operation. If the wire is not lubricated when subjected to the reserve action, an additional operation, to unwind the wire from the drum, lubricate it and then rewind it on a cone, must be performed. By simultaneously performing lubrication and reserve, these operations are eliminated and the spooled package wound on a drum can be used directly in a machine or in a loom.

  
to knit or weave. In this process, although the reservation agent only partially penetrates the coiled packet as shown in Figures 5a and 5b, the lubricant flows

  
through the whole whole coiled package lubricating evenly

  
or regularly all the fibers in it.

  
The yarn thus prepared can then be dyed as in Example 1.

  
 <EMI ID = 58.1>

  
Coiled bundles of yarn are treated by a reservation agent as in Example 1 or in Example 2. After this treatment and before dyeing, two strands of treated yarn are shaped or

  
i shaped into a fabric by weaving. The result is a three-tone fabric.

  
EXAMPLE 4

  
Coiled bundles of yarn are processed in the same manner as described in Example 1 or 2. However, after processing, a 100/26/1 treated strand of nylon 66 yarn is knitted with an untreated strand of yarn. treated 100/26/1 will deny nylon 6 and the resulting fabric is then dyed as described in Example 1. The result is a fabric in which the yarn

  
untreated is entirely dyed a very deep, deep or dark yellow and the treated yarn consists of lengths or sections of three shades or tones of blue.

  
 <EMI ID = 59.1>

  
A 1.134 kg spooled bundle of: nylon 66 yarn is processed

  
using a reservation chemical says Verona with

  
the mixture composed of 10% to 10.5% by weight of reservation agent

  
 <EMI ID = 60.1>

  
Formic acid is then added to the mixture to adjust the pH to a value between 2.5 and 3.5. The yarn is then treated as described in Example 1.

  
EXAMPLE 6

  
A coiled bundle of wire, known in the industry as

  
spool and comprising a flat wound bundle of wire of narrow or thin thickness, is placed in the apparatus according to the present invention. A reservation agent is prepared according to Example 1 or. 2. This mixture is infused into the cross coil as described in Example 1 followed by

  
by water vapor. With a flat wound package of this nature and the amount of booking agent listed, the coil package

  
 <EMI ID = 61.1>

  
absorbed to the yarn and the yarn will remain colorless during any subsequent processing.

  
The yarn can then be subsequently treated by weaving, knitting etc. with an untreated strand, after which the resulting material can be dyed, only the untreated portions of the yarn absorbing the acid dye. The treated and untreated strands can also be both dyed with a disperse, plastosoluble or dispersion dye and the treated strand can also be dyed with a cationic dye.

  
EXAMPLE 7

  
A spooled bundle of 1.134 kg of 100/26/1 denieisen nylon 66 thread wound on a drum is placed in the treatment chamber according to the present invention. A lubricant, such as mineral oil based winding oil in an amount having

  
a weight which represents 2% to 2.5% of the weight of the coiled bundle, is mixed with water at a volume ratio of approximately 7.5 to 1. The mixture is then infused into the coiled bundle of yarn, as described above in Examples 1 and 2 in conjunction with the reservation agent or with the reservation lubricant. The infusion is followed by steam at a pressure

  
 <EMI ID = 62.1>

  
The lubricant diffuses completely through the entire coiled bundle of wire lubricating it completely and evenly, so that a separate lubrication operation, during which the wire is wound onto a drum or cone and unwound from it, does not occur. is no longer needed and the yarn can then be immediately processed or shaped in a knitting machine or

  
weaving or the like.

  
The relative proportion of treating agent to the weight of the package wound can of course be varied to produce different results. So for example in a situation where a reservation agent is used, if the quantity thereof is increased, the proportion of yarn in the wound bundle, which is reserved, increases. The repeat sequences of fully processed, partially processed and untreated sections respectively are believed to depend on the relative rate of agent uptake.

  
of reservation in comparison with the speed of diffusion of the reservation agent through the wound packet. In other words, if

  
the booking agent's fixation speed is significantly higher than the booking agent's broadcast speed

  
Through the coiled bundle, the fully reserved or partially reserved segments of the wire will be relatively shorter in comparison to the untreated sections. On the other hand, when the diffusion rate of the reserving agent through the coiled bundle is significantly higher than the securing rate, the untreated lengths or portions of yarn will be relatively shorter.

  
By using a reservation agent as the treating agent and water vapor as the heated fluid according to the method according to this invention, the temperature of the water vapor used is not a critical factor unless it is. exceeds the temperature to which the reservation agent can be safely exposed.

  
The maximum temperature of the water vapor will obviously also depend on the melting or softening point of the yarn used. Normally, water vapor, at a temperature in the range of from about 107 [deg.] C to 177 [deg.] C, can be employed.

  
The water vapor employed may contain small amounts of moisture, for example about 7%. From a practical point of view,

  
it is preferable that the water vapor is relatively dry to avoid the need to dry the wound bundle of yarn after treatment in accordance with the method according to the present invention.

  
Generally, the exposure time of the coiled packet to water vapor should be at least about 30 seconds in order to obtain desirable results. Preferably, the water vapor can be directed against the coiled bundle of wire for about a minute or longer up to approximately five minutes. Although five minutes is not an upper limit

  
 <EMI ID = 63.1>

  
noticeable by the use of times exceeding five minutes.

  
The pattern or pattern of winding the wire to form a coiled bundle takes many different forms in practice. Thus, the wire can be wound on a cone or on

  
a tube or can be wound either with a constant speed and with a constant reciprocating back-and-forth motion or with

  
variations in any of these parameters. The effects, which are obtained, will obviously vary depending on the type of winding or. winding used.

  
By employing a reservation agent in accordance with the process of the present invention, the yarns thus treated will be resistant to certain types of dyes. Thus, the yarn, if dyed with such a dye, will have an area of full color, an area of intermediate color and an area of no color, corresponding to the lengths or portions which are unreserved, partially reserved or totally. reserved. Such yarns can be treated with a combination of dyes, one of which follows the scheme

  
 <EMI ID = 64.1>

  
reservation, thus producing a completely unique and different appearance. This same type of dye sensitivity or. at

  
dyeing and mixing dyes can be employed for

  
 <EMI ID = 65.1>

  
treated yarn and one or more strands of untreated yarn to give very pleasant and diverse effects, multicolored, multicolored or variegated.

  
Another use of the device according to figure 1 is <EMI ID = 66.1>

  
 <EMI ID = 67.1>

  
differently colored are supplied to the dosing means 35 and 36

  
and the above-described process is then carried out, By an appropriate choice of the amount of dye, it is possible, for example, to obtain a penetration of the upper half of the coiled bundle by a color and a penetration of the lower half by a color. second color. With additional dye some mixing will obviously occur in the middle region of the. package wound and it will thus present a color which is a mixture of the first and second colors. Alternatively by using lesser amounts of dyestuffs, an undyed portion in the middle region is obtained.

  
Another embodiment of the apparatus, which is mainly usable for direct dyeing according to the present invention, is shown in Fig. 6. As this

  
Indicated therein, a manifold assembly, generally of the type shown in Figure 1, is shown. However, as can be seen, a partition wall or dividing wall 105, for example a gasket packing, is introduced into the manifold 19, in a manner which divides both the region or surface of the perforated plate 21 and the cavity. 24 inside the manifold 19. In the embodiment shown, the wall or partition 105 extends along a diameter of the plate 21, thereby dividing the cavity.
24 in half-cavities 24a and 24b.

  
As further shown in Figure 6, the tube
32a is connected to the half-cavity 24a and the tube 32b is connected to

  
 <EMI ID = 68.1>

  
metering or measuring devices such as means 36, not shown. It should also be understood that another manifold, similar to the one shown in figure 6, is also employed with tubes
-1 25a and 25b, not shown, connected to two additional measuring or metering means, not shown. Thus, two different dyes, for example respectively red and yellow, can

  
be introduced in a metered manner respectively into the half-cavity 24a through the pipe 32a and into the half-cavity 24b through the pipe 32b, as described above in correlation with figure 1. Similarly, two additional dyes can be introduced into the opposite collector, not shown, thus allowing the introduction of four coloring materials

  
in a coiled package. In addition, the cavity 24 can be shared

  
in addition to two separate sub-cavities thus making it possible to use more than four different dyes to treat

  
a single coil bundle of wire.

  
Examples of direct dyeing in accordance with the present invention are set forth below.

  
EXAMPLE 8

  
A spooled bundle of polyester yarn was dyed with a plurality of coloring materials using the apparatus shown in Figure 1 as modified in accordance with the device shown in Figure 6. The yarn, which was dyed, was in the form of. a spooled bundle of 1.021 kg of 18/1 cc polyester thread wound on a drum. The respective upper and lower manifolds and the respective perforated plates in the apparatus were each divided into two sections by a gasket-like material so as to allow separate introduction of four different dye solutions. Below are shown, in tabular form, the solutions which were placed in the four respective dosing vessels connected to the four sections of the manifolds.

  
Upper manifold

  
(1) First dye solution

  
13.3 ml of yellow dye known as Foron Yellow SEGLG

  
d 3.3 ml of Foron Navy 2GL

  
33.4 ml of water

  
(2) Second dye solution

  
8.3 ml of red dye known as Foron Red OWE 8.3 ml of yellow dye known as Foron Yellow SRL
33.4 ml of water

  
Lower manifold

  
(1) First dye solution

  
 <EMI ID = 69.1>

  
33.4 ml of water

  
(2) Second dye solution

  
11.6 ml of red dye known as Foron Red OWE

  
5.0 ml of yellow dye known as Foron Yellow SEGLG

  
33.4 ml of water.

  
The coloring materials were high energy Foron products sold by the American company called Sandoz Color

  
& Chemical Manufacturing Co. and in each case the colourant employed was a 5% solution dispersed in water.

  
Using a pressure of approximately 4.14 bar, the upper and lower perforated plates, respectively, were contacted with the upper ends, respectively.

  
and bottom of the coiled bundle of wire. Dye solutions

  
 <EMI ID = 70.1>

  
after 30 seconds using a pressure of approximately 1.03bar. Water vapor, at a temperature of approximately
160 [deg.] C and at a pressure of 6.21 bar, was then introduced into the coiled bundle for approximately two minutes.

  
The resulting coiled bundle of thread was multicolored, one

  
halves of the top portion being tinted pale green while the other half of the top portion was tinted

  
in a peach color. One of the halves of the lower portion! I

  
was dyed a medium blue color and the other motie of the lower portion of the coiled bundle was dyed pale pink.

  
 <EMI ID = 71.1>

  
no undyed areas of yarn in the coiled package. The dyed yarn thus consisted of contiguous repeating lengths or portions of four colors.

  
If it is desired that a portion of the yarn remain undyed, the amounts of dye solutions are reduced proportionally. Conversely, if it is desired to have an overlap between the dyed sections of the wound bundle of yarn and thus obtain a mixture of the coloring matters in certain portions of the bundle

  
 <EMI ID = 72.1>

  
correspondingly. It is clearly within reach of

  
the skill in this field of the art to increase or decrease the proportional amounts of dye solutions to achieve desired variations in dyeing, shades or tones of color, and undyed areas.

  
&#65533; 9

  
Polyester yarn, dyed as described above in Example 8, together with undyed strands of an acid dyeable nylon are knitted to form a fabric. The resulting fabric has areas of pale green, peach, dew, blue and white. This fabric is then dyed in a conventional manner using acidic dyes which only color the nylon strands. In this way, unique and attractive fabrics can be obtained.

  
It is evident that the important advantages of yarn dyeing according to the present invention are the simplicity of the process, the use of a minimum amount and the full utilization of the coloring materials, the absence of effluent which must be drained off and low energy requirements.

  
 <EMI ID = 73.1>

  
above, the preferred means for achieving selective distribution or distribution of a yarn treating agent in a coiled bundle of wire is a perforated plate which is in contact with one end or both ends of the coiled bundle . He must

  
 <EMI ID = 74.1>

  
a cylindrically shaped element having perforations around

  
 <EMI ID = 75.1>

  
the yarn treatment agent is introduced through the circumferential surface of the coiled bundle of yarn or through selected portions thereof.

  
Although the illustrative examples, set forth above, involve

  
treatment of specific fibers, it should be understood that the methods of the present invention can be employed to treat

  
any type of fiber with the desired type of treating agent. From

  
fibers which can be treated or dyed by the present process

  
are nylon fibers, acrylic fibers, wool fibers

  
and polyester fibers as well as mixtures thereof.

  
The following forms of light and heavy denier fibers are

  
examples of those that can be handled in accordance with

  
present process: fibers for carpet; fibers for clothing or

  
clothes; fibers used in woven, tufted fabrics,

  
knitted, flocked and non-woven; and fibers in the unfinished state

  
or not textured from a feeder.

  
the present invention can also be used to carry out

  
the following treatments in addition to the application of reservation agents, dyes and lubricants: application of flame retardants and water repellents or water repellants

  
 <EMI ID = 76.1>

  
yarn or fiber dyeing study; treatment to weaken

  
f or to strengthen the yarn or fiber; heat fixing of the yarn or fiber; and the like.

  
In an optional embodiment of the present invention, a pre-measured or dosed amount is pre-packaged or conditioned of yarn processing material, such as

  
than a booking agent, is placed on top or top or

  
on the base or bottom of the coiled bundle of wire before the coiled bundle is placed in the present apparatus. In this embodiment of the invention, the apparatus, associated with the addition of the treatment material (35 and 36), would not be necessary. After the coiled bundle has been placed between collectors 12 and 19 and

  
the manifold 19 has been lowered until it comes into contact with the top of the coiled packet, the heated fluid is pumped to be introduced into the coiled packet as has been described previously. In this embodiment of the rod in the others described above, the coiled package is totally reserved in an entire determinable portion thereof with a second partial reserve area

  
at the end of the totally reserved area and a third area with no reservations.

  
The container, for the pre-metered and pre-packaged amount of process chemical, is constructed of a material which is porous to the transmission of the heated fluid or is soluble in the heated fluid, so that upon contact with the heated fluid, the container dissolves and allows the infusion of the treatment material into the coiled bundle of wire. In

  
a preferred embodiment of the present invention, a means

  
 <EMI ID = 77.1>

  
between the amount of process chemical and the coiled bundle of wire. The filter media or media traps or retains any unwanted residue of the treatment material for easy removal and disposal.
