CONTINUOUSLY AND COMBININGLY OPERABLE BREADTH EXPANSION
AND VIBRATION ENHANCED SPRAY DYEING MACHINE
BACKGROUND OF THE INVENTION
1. Field Of The Invention
The present invention relates generally to a continuously and combiningly
operable
breadth expansion and vibration enhanced spray dying machine (hereinafter as
"continuous spray dyeing machine") which is an highly efficient environment-
preserving continuous spray dying and processing apparatus.
2. Description Of The Prior Art
The term continuous spray dying machine used herein is intended to indicate a
dying
and processing apparatus which provides the fabric continuous dyeing and other
processing. The fabric is continuously proceeded and substantially fully
expanded in
the breadthwise direction. The liquid dye and other fabric treating agents are
brought
into contact with the fabric in an atomized form by means of spray nozzles
arranged
above the fabric. A high speed air stream is formed under the fabric to create
a low
pressure zone which cause a pressure difference between the upper and lower
sides of
the expanded fabric. The static pressure above the fabric is greater than the
pressure
below so that the fabric can not only levitated and freely expanded in breadth
direction
via the high speed stream of the air flow, but the fabric in motion can also
periodically
vibrate violently via the unbalanced pressure.
This vibration provides the energy for the dye, treating agents, or oxidation
gases to
penetrate into the fabric texture so as to enhance the absorption rate and
diffusion speed
the dye into the fabric. Thus a continuous dying and processing operation with
high
efficiency, low energy consumption, low bath ratio and low pollution may be
achieved.
The present invention is particularly related to an effect that is caused by
the high
speed air streams formed by a cloth guide tube. This does not only enhance the
penetration and diffusion of the dye, but also speeds up the penetration of
the oxidation
gases to have a quick dye development when performing low temperature
oxidation
reduction dying. When performing other processing. It also provides a very
efficient
way to remove unwanted particles or impurities from the fabric so as to
efficiently finish
the operations of desizing, scouting, bleaching, soaping, reduction, enzyme
treating,
rinsing, relaxation, and drying. Therefore, the present invention can complete
the
overall dyeing and processing operations in a very short time as compared with
the
CA 02389678 2002-04-30

conventional dyeing apparatuses.
A conventional continuous dyeing machine is defined to be one that combines
more
than two machines with different functions to perform the dyeing process in a
continuous way. When dyeing, there are three steps: dye padding, dye
development
and fixation, and washing and drying operations. The popular conventional
continuous
dyeing machines are developed by improving the design of the dye padding
operation.
To accomplish some operation, some designs follow a particular dyeing method;
others
choose a specific combination of individual machines. Therefore, to obtain a
most
reasonable manufacturing procedure of due to the limitation of the factory
environment,
the preprocessing operations are t usually separated from the dyeing
operation. Please
refer to Figures 1 and 2. Fig. 1 is a side view of the combined structure of a
conventional dye padding continuous dying machine. Fig. 2 shows a side view of
a
conventional continuous breadth expansion washing machine. Referring to Fig.
1, the
combined structure comprises (listed according to the manufacturing order): a
dye
padding machine A, a steamer or a dryer B, an air oxidation machine C, a
treating agent
padding machine D, a steamer E, a washer F, a water remover G, and a dryer H.
All the
machines are connected in series and the fabric is drawn by the driving roller
and cloth
guide axis on each machine to continuously pass through each machine. To keep
the
fabric proceeding in a continuous way and fully expanded in width, the
longitudinal and
transverse directions of the fabric have to be stretched with a big tension.
Therefore, referring to Fig. 3A, the conventional continuous dyeing machine
drags the
fabric to pass the dye padding machine A and absorb the dye by a driving
roller A1 and
a pressure roller A2 on the dye padding machine. Thus, the size of the contact
surface
between the two rollers directly affects the dye padding rate, which in turn
affects the
depth of dyeing. To prevent the occurrence of color difference on both sides
of the
fabric, in addition to apply even pressure on both sides of the dye padding
roller, the
middle of the pressure roller must meet crown standard so that the dye and
treating
agents can be evenly distributed. Figures 3B and 3C are the side views of the
other
commonly seen dye padding machines. The fabric past the dye padding machine A
is
immediately sent into and passes through the steamer B. There are many
different
forms for the steamer B, bur all perform a single operation. It is different
from the usual
discontinuous dyeing machine. For example, the air flow type or liquid flow
type
dyeing machine can simultaneously perform continuous dye cycling and support
to
perform dyeing at the same time. The fabric passes through the steamer B or
the air
oxidation machine C to have the dye developed and fixed. The proceeding of the
fabric
is supported by a cloth guide axis set B 1. When the dye gets fixed, the
fabric is then
CA 02389678 2002-04-30
- 3 -
guided into the washer F to remove the unfixed dye, remaining chemicals, or
other
impurities. Usually, the washer F has each as a unit F1 and several units are
connected
into a group. In the tubs are stored with a larger amount of water. A water
removing
pressure roller F2 is provided at the upper outlet of each tub. For the usual
washers, a
group has at least three tubs and up to fifteen tubs. The number depends upon
the
processing after dyeing. In conventional dye padding machines and steamers,
the
processing after dyeing includes operations such as re-oxidation, acid
washing,
neutralizing, hot showering, soaping, hot showing, and cold washing.
Therefore, the
washer with a group of seven to nine tubs is the best choice. After water
washing and
water removing, the fabric is guided into the dryer H to get dried. Usually,
the dryer is
consisted of several drying tubs. After dye padding, the fabric needs to be
processed
by dye development and fixation immediately and thus the dye development and
fixation processing machine should be attached immediately after the dye
padding
machine.
So the conventional continuous dyeing machine is formed by connecting several
different machines together to achieve the goal continuous dyeing and
processing. In
practice, using the dye padding machine A to dye and proceed the fabric often
makes the
fabric without soft touch or has the problem of linearly folded dyeing. To
ensure that
the fabric can be fully expanded in width for dyeing and proceeding, the
longitudinal
tension is often greater than l.Skg F(per centimeter in which) in addition to
the
stretching in the transverse direction by a fabric stretching machine.
Therefore,
conventional continuous dyeing machines can only perform dyeing and processing
on a
tatted fabric, but the problem existing in the knitted or elastic fabric could
not be
resolved to date. Furthermore, in her dyeing process by the dye padding
machine,
although a small liquid amount dyeing can be achieved, yet the dyeing process
can only
be performed once. When performing dye development and fixation in the
steamer, it
cannot continuously supply the dye at the same time, and therefore the fabric
can not
obtain a deep color. When washing the fabric, a large amount of water is
needed for
cleaning. For a new generation of environment-preserving dyeing machine, the
above
mentioned continuous dyeing machine obviously needs many improvements and
modifications.
Please refer to Fig. 4, which shows another spray dyeing apparatus with
breadth
expansion and vibration-enhanced dyeing operation invented by the inventor of
this
current invention. It is disclosed in the R.O.C. Pat. No. 098,316, the U.S.
Pat.
No.5,775,136, and the PCT Pat. No. W098/49383. The present invention is an
improved invention derived from the existing technology principles and
characteristics.

Please refer to Figures 4 and 6. Fig. 4 is a side view of a spray dyeing
apparatus
with breadth expansion and vibration-enhanced dyeing operation. Fig. 6 is a
side view
of the structure of a continuous spray dyeing machine according to the instant
invention.
The part of air guiding nozzle design is almost the same in the principle and
structure.
However, the application of the air guiding nozzles in the current invention
is different
from the previous patent. For the convenience of the examination procedure,
this point
has to be explained. The biggest difference is that the previous case is a
discontinuous
dyeing apparatus which can only provide a small amount of dyeing and
processing; yet
the continuous spray dyeing machine in the present invention can not only
continuously
perform processing in a processing tub, but also, by connection with other
machines,
continuously complete the operations such as dyeing, treating agents
absorption, steam
dye development, air dye development, dye fixing, washing, and drying. In
particular,
to facilitate even absorption or to promote the production rate, the
processing tubs can be
arbitrarily added to obtain the necessary quality and production rate.
Therefore, in
observation of the defects in the discontinuous spray dyeing apparatus with
breadth
expansion and vibration-enhanced dyeing operation and the above mentioned
conventional continuous dyeing machines, the application technology of the air
guiding
nozzles should be improved for a better environment-preserving dying method.
Accordingly the inventor hereby provides another mass production type
continuous
dyeing apparatus.
SUMMARY OT THE INVENTION
The present invention provides a continuous spray dyeing machine, which allows
the fabric to be levitated, expanded, and violently vibrated by a high speed
air flow in
dyeing and other processing operation so as to complete the processing in a
short period
of time.
The invention also provides knitted fabrics of other elastic fabrics a breadth
expansion continuous spray dyeing and processing. Furthermore, the present
invention
provides a continuous spray dyeing machine, which can achieve the goal of
continuous
processing by combining different machines. It can also be arbitrarily
modified, adjusted,
expanded or reduced according to the manufacturing procedure and, therefore,
can
obtain the most economical dyeing and processing operations.
Yet, the present invention provides a continuous spray dyeing machine, in
which
the fabric is proceeded simultaneously in each sector in a folding collective
way. In each
sector, the fabric is dragged by one cloth-dragging wheel. Thus the tension on
the
CA 02389678 2002-04-30
- 5 -
fabric can be minimized and the usual bad soft touch problem of the fabric
processed by
ordinary padding continuous dyeing machines can be improved.
Moreover, the present invention provides a continuous spray dyeing machine,
which can not only provide usual dispersive and reactive dyes, but also
perform the
spray dyeing operation with low temperature reduction dye liquor under a
nitrogen gas
(inert gases) mediated environment in the upstream processing tubs. When the
fabric
passes through the next processing tub, the reduction dye liquor can be
oxidized for
dye development by the large amount of fresh air sprayed out of the air
guiding
nozzles.
Yet further, the present invention provides a continuous spray dyeing machine,
in
which the lower side of the fabric is provided with a high speed air flow for
the fabric to
periodically vibrate violently when the fabric pass through each processing
tub.
Therefore, dyeing, treating agents or re-oxidation air can quickly penetrate
into the
fabric texture with the help of this vibration so that a highly efficient
small amount
dyeing and processing operations can be achieved.
A further object of the present invention is to provide a continuous spray
dyeing
machine, in which the lower side of the fabric can be provided with a high
speed air
flow containing dyes or a large amount water ejected from the air guiding
nozzles when
washing or dyeing the fabric with a compact texture. The fabric thus processed
can be
dyed on both sides and the impurities remaining on the fabric can be quickly
diffused
into water.
So the present invention can achieve the goal of instant washing and enhanced
dyeing. Yet, another object of the present invention is to provide a
continuous spray
dyeing machine, which can, in addition to providing a small amount, high
concentration
dyeing via a periodically violent vibration on the fabric, enhance the
removing ability of
the impurities existing in the texture so that operations such as desizing,
scouring,
bleaching, soaping, washing can be quickly finished.
So the invention provides a highly efficient cleaning effect for the dyed
fabric.
Moreover, the present invention provides a continuous spray dyeing machine,
which can
not only provide dyeing and other wet type processing operations, but also
dries the
fabric by the dry and hot air flow coming out of the air guiding nozzles. It
can blow
the outer cold air to lower the temperature.
To achieve the above objects, the continuous spray dyeing machine provided by
the
instant invention has processing tubs for connections to perform simultaneous
dyeing,
wherein each processing tub is designed with the same principle and structure.
To
processing tub comprises a cloth collecting tub, a cloth guide tube, an air
guide nozzle,
CA 02389678 2002-04-30
- 6 -
cloth dragging wheel, a blast machine, a dye pump, a cloth wiggling machine,
an air
heater, a dye heater, an air cooling inlet, an exhaust outlet, a nitrogen
inlet, a steam inlet,
an air filter, a dye filter, pipes connecting each parts and controlling
elements for each
part.
Each of the front and rear ends of the processing tub of the continuous spray
dyeing
machine of the invention is provided with a passage, the left and right sides
and the left
and right walls of the processing tub form a parallel wide passage for the
fabric to enter
and pass through in a breadth expansion way. A cloth collecting tub is
provided under
the passage entrance close to the bottom of the tub in the upstream sector
where the
fabric can be folded and collected to an expected amount. The fabric then
slows down
in moving so as to disperse the tension in continuous proceeding. A cloth
guide tube is
formed in the downstream of the passage. One or a plurality of sector
separated air
guiding nozzles are provided along the direction of the passage on the cross
section of
the side wall under the cloth guiding tub. These nozzles are connected by
pipes to a
blast machine for guiding and ejecting pressurized air. One or a plurality of
dye
nozzles are provided above the cloth guide tube and connected with pipes to
the dye
pump for guiding and ejecting the dye or treating agents onto the surface of
the fabric.
A dynamical cloth dragging wheel is provided under the downstream outlet of
the
passage for dragging the fabrics in the cloth collecting tub to pass through
the cloth
guide tube. The fabric can then continuously proceed to enter the next
processing tub
and receive another processing operation. Therefore, when performed with
dyeing and
other processing operations, the fabric can have a full contact with the
atomized dye
particles ejected out of the dye nozzles to achieve the goal of small amount
dyeing.
Whenever the fabric gets in touch with the dye, the fabric generates a
periodically
violent vibration due to the high speed air flow ejected from the air guide
nozzles.
Thus, the dye, and chemicals or re-oxidation gas can obtain the energy
necessary for
penetrating into the fabric texture. The absorption rate and diffusion speed
of the dye
into the fabric can be thus enhanced and a continuous dyeing and processing
operation
with high efficiency, low energy consumption, low bath ratio and low pollution
may be
achieved.

721, a jet nozzle 722, a valve 103, an outlet cloth wiggling machine 11, a
valve 103, an
outlet cloth wiggling machine 11, and a dye confluent circulation 54.
Please refer to Figures 5,6,7,8 and 9. The processing tub 1 has same design
and
specification on the front and rear sides for convenience of interconnection.
An inlet
passage 101 is provided above the side walls in the upstream of said
processing tub
CA 02389678 2002-04-30
_ $ _
passage, while an outlet passage 102 is formed above the side wall in the
downstream of
said processing tub passage. In addition, the left and right sides of each
passage and
the left and right walls of the passage in said processing tub 1 form a
parallel passage
with a wide open cross section for the fabric 2 to enter and pass through said
processing
S tub 2 in a breadth expanded manner. The downstream end 402 in the lower
processing
tub 2 is lower than the upstream end 401. They form a slant surface with a
small angle
for circulation liquid to quickly gather at the lowest place and return to the
dye
preparation tub via a recycling pump 17. A cloth collecting tub 4 is provided
in the
upstream sector of said processing tub 1 passage. The tub bottom is composed
of a gas
liquid separation net plate 41.
A cloth guide tube 5 is formed in the down stream sector of said processing
tub 1
passage. One or plurality of dye nozzles 71 are provided on the upper side
walls in
said cloth guide tube 5 passage. An air distributing tube 62 is provided at
the position
outside the lower passage and in the same direction as said cloth guide tube 5
so that the
lower flat wall of said cloth guide tube 5 and the upper wall of said air
distributing tube
62 share the common wall 52. Said common wall 52 (also known as reflective
action
base 52) is provided with one or a plurality of sector separated air guiding
nozzles 51
along the passage on the cross section of said common wall 52. The upstream
end of
said common wall 52 is connected with said gas liquid separation net plate 41
under said
cloth collecting tub 4. The downstream end of said common wall 52 is connected
with
said outlet passage 102. So said common wall 52 forms a slant angle so that
the
upstream end is lower than the downstream end. A cloth dragging wheel 3 is
provided
below said outlet passage 102. A cloth wiggling machine 8 is provided below
said cloth
dragging wheel 3 in the downstream direction. Said cloth wiggling machine 8
can
connect via a dynamical transmission device to wiggling plate for it to wiggle
in the
longitudinal direction. In the connection portion of said common wall 52 and
said gas
liquid separation net plate 41. A dye circulation guiding plate 53 is formed
by extending
said common wall 52. One or a plurality of dye confluent circulation 54 is
provided in
the downstream sector of said dye circulation guiding plate 53. An air
circulation
passage 63 is formed between said circulation 54 and the passage. Therefore,
the
circulation dye from said common wall 52 would not mix with the circulation
airflow
when passing through the confluent circulation.
On the left and right walls in the downstream and said processing tub 1
passage.
A hidden blast machine 6 is provided under said air distributing tube 62. Said
hidden
blast machine 6 is provided with an even flow cylinder 64 at the inlet end.
The inner
space of said even flow cylinder is formed with an air filter 602. The outlet
of said
CA 02389678 2002-04-30
- 9
blast machine 6 is connected with said air distributing tube 62.
As described in the above continuous spray dyeing machine, dragged by said
cloth
dragging wheel 3, said fabric folded and collected in advance in said cloth
collecting tub
4 can pass through the surface of said common wall 52 (reflective action base
52) below
said cloth guide tube 5. The dye or treating agents in said preparation tub 9
can be
pressurized by said dye pump 7 to go through a transmission pipe 72, a filter
701 and a
heat exchanger 702 and enters said dye nozzle 71 in said cloth guide tube 5
for spraying
on the upper surface of said fabric. Therefore, when dyeing or performing
other
processing operations, said fabric 2 can be stretched to a fully breadth
expansion by the
high speed air flow ejected out of said air guiding nozzle 51 and pass through
said cloth
guide tube S. Said fabric 2 can be distributed and covered from above with the
atomized particles of dispersed dye and treating agents ejected from said dye
nozzle 71
above said cloth guide tube 5. The dyeing effect is achieved by the
penetration of the
dye from the top surface to the bottom. On the bottom surface of said fabric
2, a high
speed air flow ejected from a plurality of sector separated air guide nozzle
51 is provided
to form a levitating force for said fabric 2 in a cooperative and relay
method. The air
flow also produce a difference in pressure between the upper and the lower
sides of said
fabric 2, the lower side being lower in pressure due to the higher speed air
flow while
the upper side being higher in pressure due to the slower air flow. Therefore,
the upper
and lower air flows interact to make said fabric perform a periodically
violent vibration.
The upper air flow with higher pressure also force the air flow to be expelled
out from
the left and right sides under said fabric 2. When passing through said cloth
guide tube
5, said fabric does not only have a periodically violent vibration but also
get fully
stretched in the breadth direction continuously. The dye and solution not
being
absorbed by said fabric 2 will be sent back to said dye preparation tub 9 by a
dye cycling
pump 17 or be redirected to said processing tub 1 in the downstream for
spraying again.
If it is in the washing process, the liquid can be discharged.
The gas part is connected with said blast machine 6 by an air circulation even
flow
cylinder 64 (an additional circulation tube and transmission pipe should be
added if a
hidden blast machine is not employed) do that the air in the tub can be
compressed by
said blast machine 6 and sent via the transmission pipe through an air filter
602 and an
air heat exchanger 601 into an air distributing tube 62. The air is then
ejected toward
the upstream direction of said cloth guide tube 5 by said air guiding nozzle
51 along the
upper surface of said reflective action base 52. Thus, the air flow motion has
an
opposite direction to the motion of said fabric 2. Said fabric 2 can obtain a
steady
motion because the friction between said cloth dragging wheel 3 and said
fabric 2 is
CA 02389678 2002-04-30
-
greater than the force exerted by the air flow. Therefore, said cloth dragging
wheel 3
has to provide a greater dragging force than the force exerted by the air flow
so that said
fabric can proceed steadily. In fact, said fabric 2 in said processing tub 1
can have its
motion in the same direction as that of the air flow to facilitate dyeing. The
difference
5 between dyeing with the same direction of motion and the opposite direction
of motion
is not significant. However, in operation, the opposite direction of motion
provides a
better stability for the motion of said fabric 2 than the same direction of
motion. In
other words, the same direction of motion is mote suitable for discontinuous
dyeing
machines, which had been explained in details in the previous patent of the
same
10 inventor and will not be described further herein. Basically, in the fields
of discontinuous
and continuous dyeing, there is a big difference in the requirement of the
fabric
proceeding speed. The reason is that for continuous dyeing machines, said
fabric 2
only receives on process when passing through each machine, therefore in a
limited
equipment and time it is better to slow down the speed of said fabric 2 to
ensure a
complete level dyeing and better quality. When said fabric 2 and the air flow
have
opposite directions of motion, the speed of said fabric 2 can be completely
controlled by
said cloth dragging wheel 3. Therefore, the synchronous issue is not a problem
in
operation. The energy of the air ejected out of said air guiding nozzle5l can
be totally
converted into the energy necessary for the vibration of said fabric 2. In
addition,
another object is that most of the pollution materials can be removed along
with the air
flow and circulation liquid in dyeing or impurity processing. Furthermore, a
washing
nozzle 721 is provided on the upstream end within said air distributing tube
62 and
connected with a high pressure washing pump or a water tank by said
transmission pipe
74. Another transmission pipe 73 is formed on said transmission pipe 74 and
connects
to said dye transmission pipe 72. A reverse control valve is provided in each
pipeline
to control the ejection of water or the mixture of water and dye by opening
and closing
of the valve when washing or dyeing a particularly compact fabric. The ejected
liquid
is then ejected toward and mixed with the air flow in said air distributing
tube 62 so that
the large amount of water or dye ejected out of said air guiding nozzle 51 can
get in
touch with said fabric 2. This allows the impurities or treating agents
remaining on
said fabric 2 to quickly diffuse into water. Even if said fabric 2 is dyed on
both sides,
another steam pipe can be provided on said transmission pipe 74 and a reverse
control
valve 641 can directly provide the necessary temperature in said processing
tub 1.
When said fabric 2 enter the next processing tub l, the action of said
wiggling
plate 8 can make said fabric 2 fall into said cloth collecting tub 4 get the
best folding.
To facilitate the examination procedure, the following paragraph further
explains in
CA 02389678 2002-04-30
- 11
details the effect happening in said cloth guide tube.
According to the Bernoulli's law, "the place where the flowing liquid of gas
has a
faster speed has a lower pressure." Therefore, as describe above, when a high
speed air
flow is formed under said fabric 2, the pressure below said fabric 2 is lower
than the
S pressure thereabout because of a slow air flow. So said fabric 2 will be
dragged toward
the high speed air flow area due to both the pressure difference and the
gravity 8. Thus
said fabric 2 has a close contact with the high speed air flow and the
friction in between
increases so that said fabric 2 obtained the most energy from the air flow.
Thus,
whenever said fabric 2 gets close to the mainstream of the high speed air
flow, it will be
drawn by the air flow and could not keep going forward. Since the mainstream
of the
high speed air flow has a greater kinematic energy, said fabric 2 moving
forward would
get continuously levitated and move above the flat wall to prevent the
friction between
said fabric 2 and the pipe wall. Whenever said fabric 2 is forced into the
mainstream
area of the high speed air flow, the air flow would generate a pressure peak
and force
said fabric 2 to quickly move away form the mainstream area. The generation of
the
pressure peak is caused by the conversion of the kinematic energy into the
pressure
energy due to resistance. It can be affected by the reflection of said flat
reflective
action base 52 and due to the same phase as another peak so that another
pressure peak
can be produced instantaneously. This pressure peak continuously happens to
said fabric
2 in a periodic way along said cloth guide tube 5. Therefore, any part of said
fabric 2 can
have a periodic vibration. The vibration frequency is determined not only by
the mass of
said fabric 2 but also by the momentum of the air flow. Thus, in dyeing or
processing
operations, both the opening extent of said air guiding nozzle 51 and the
output power of
the blast machine can control the vibration frequency. The generation of the
above
periodic wavy vibration is the effect of the work done by a large amount of
energy. Each
vibration does not only loosen the texture structure of said fabric 2 so that
the dye can
have its circulation passage, but also make the dye obtain the energy
necessary for
penetrating into the texture. This further enhances the absorption rate and
diffusion
speed of the dye on fabric. Accordingly, in the process of dyeing, in addition
to
obtaining the small amount high concentration, high efficiency, low energy
consumption,
low bathing ratio and low pollution dyeing, the fabric can also achieve the
deboundling
and relaxing effects via the periodic violet vibration. At the same time, the
impurities on
the fiber can be so efficiently removed that processing operations such as
desizing,
scouring, bleaching, reduction, enzyme treating, soaping, washing can be
quickly
finished. Thus, the invention can achieve the goal of both dyeing and further
processing
operations within an extremely short period of time.
