2. Description of the Related Art As is well known, dyes and pigments conventionally provided in the form of powder, or treated powder agents such as surfactants and scouring agents, are not directly put into a cloth treating machine such as a dyeing machine. Instead, the processing liquid (usually water or hot water) is treated with a powder agent (dye, etc.) in a dissolution tank attached to the processing machine.
It was inevitable to disperse or dissolve the above, or to disperse or dissolve the treated powder in another agitation and preparation device to carry the treated liquid to a cloth treating machine to supply the treated liquid.

Therefore, conventionally, it is necessary to provide a space for the preparation of the treatment liquid in the factory, and the labor is required for the preparation and transportation of the treatment liquid and the cleaning of the dissolution tank, the liquid preparation device, and the transportation container. It is also bulky, and the treatment liquid is lost due to transfer of the treatment liquid, color stains and loss due to unavoidable scattering during preparation of the treatment liquid (particularly dyeing liquid), and impureness of the treatment liquid due to residual treatment liquid of the previous preparation. Concentration variations due to individual differences in the person who prepares the treatment liquid, changes in the properties of the treatment liquid due to the length of time elapsed from preparation to fabric treatment (especially for reactive dyes and acidic direct dyes, due to hydrolysis, etc.) There was a problem that should be improved in terms of large changes.

EXAMPLES The method of the present invention and the cloth treating machine used therefor will be described in more detail based on the jet dyeing machine (first embodiment) and the beam dyeing machine (second embodiment) shown in the accompanying drawings. To do. 1 is an explanatory view of the mechanism of the jet dyeing machine according to the first embodiment, FIG. 2 is an explanatory view of the mechanism of the beam dyeing machine according to the second embodiment, and FIG. 3 is an example of direct injection of treatment powder (dye). FIG. 4 is a partially enlarged cross-sectional view illustrating another example of direct injection of the treated powder agent (dye), and FIG. 5 is a partially enlarged sectional view illustrating still another example of direct injection of the treated powder agent (dye). FIG.

1 and 2, T indicates a dyeing tank, and in the jet dyeing machine of FIG. 1, the cloth C is dyed in a dining sink S installed at the bottom of the dyeing tank T. While being immersed in the (treatment liquid) D, it is set in the dining sink S endlessly through the liquid flow pipe P via the drive reel R. On the other hand, in the beam dyeing machine shown in FIG. 2, the cloth C is set in the dyeing tank (T) in which the dyeing liquid (treatment liquid) D is stored while being wrapped around the beam B consisting of a perforated cylinder in a spread-like manner. become.

Therefore, in the jet dyeing machine of FIG.
The processing liquid D, which is the dyeing liquid, is stored in the dining sink S, and is pumped by the circulation pump 1 to be heated by the heat exchanger H and passed through the filter 3. The impurities are removed and the liquid feed pipe P is discharged from the jet nozzle N. It is a mechanism that assists the contact efficiency between the cloth C and the dyeing liquid D by ejecting the cloth C toward the passing cloth C. The dye liquid D sprayed from the jet nozzle N onto the cloth C flows down the liquid feed pipe P and flows back to the dining sink.

On the other hand, in the beam dyeing machine of FIG. 2, the dyeing liquid as the treatment liquid D is stored in the dyeing tank T in the dyeing tank, and the dyeing liquid D thus stored is a powerful circulation pump 1
Is forcedly circulated in the forward and reverse directions through the circulating liquid passage 4. Reference numeral H in the drawing denotes a heat exchanger interposed in the circulating liquid passage 4 and heats the dyeing liquid D to a high temperature. In the figure, reference numeral 5 is a sampling pressure plug, reference numeral 6 is a pressure control valve, reference numeral 7 is an overflow pipe, reference numeral 8 is a water tank, and reference numeral 9 is a constant pressure pump for sending hot water from the water tank 8 to the circulation pump 1, Reference numeral 10 is a four-way stopper.

The most important point in the present invention is that in the above-mentioned jet dyeing machine, beam dyeing machine, or conventionally known cloth treating machines such as Jigger dyeing machine and Wins dyeing machine, there are always places where turbulent flow and vortex flow occur strongly. Paying attention to certain things, when cloth treatment powder (dye or pigment) is added to or near the place where the turbulent flow or vortex flow occurs, the action of stirring and dispersing or dissolving due to the violent behavior of the solvent liquid flowing there is skillful. It is in the point used for. Then, Fig. 1
In the first embodiment shown in FIG. 1, a circulation pump 1 that causes a vortex flow
2 is provided in the vicinity of the suction side so that the dye (treatment powder) d is introduced from there, and in the second embodiment shown in FIG. 2, the inlet 2 is provided on the inlet side of the circulation pump 1. The dye (treatment powder) d is added.

As in the first embodiment of FIG. 1, when the dye (treatment powder D ') is introduced from the inlet 2 near the suction side of the circulation pump 1, the treated treatment powder d is sucked into the circulation pump 1. It is pumped and vigorously stirred by a strong vortex generated near the pump discharge port, and then dispersed or dissolved in the solvent liquid D ′ to become a dyeing liquid (treatment liquid) D, which is a dining sink S or liquid of the jet dyeing machine. It reaches the pipe P and the jet nozzle N.

Further, as in the second embodiment of FIG. 2, when the dye (treatment powder) d is introduced into the circulating liquid passage 4 from the introduction port 2 in the vicinity of the liquid mouth of the dyeing tank T, the introduced treatment powder d is concerned. The turbulent flow of the rapidly flowing solvent liquid D'in the partial circulation liquid path 4 disperses or dissolves in the solvent liquid D'and quickly becomes the dye liquid (treatment liquid) D, which is the dining sink of the dyeing tank T machine. S and the whole circulation liquid path 4 will be spread.

Therefore, the method of adding the treatment powder d to the solvent liquid D'in the present invention will be described as follows.

First, in FIG. 3, what is indicated by reference numeral 11 is a powder bucket. The dust bucket 11 has a shutter tube 11a having a flange-like edge hooking portion which can be hooked on the edge of the inlet of the jet dyeing machine of the first embodiment or the beam dyeing machine of the second embodiment. This shutter cylinder 11a
And a long cylindrical member 11b with a bottom having a flange-shaped retaining portion at the bottom edge and a large number of punch holes drilled in the body periphery. It is configured. Then, the powder bucket 11 is filled with a predetermined amount of dye (processing powder) d, and the charging port 2 of the dyeing machine is filled.
, The flange-shaped edge hooking portion provided on the upper edge of the shutter tube 11a is hooked on the edge of the charging port 2, and the bottomed tubular member 11b is allowed to flow for the solvent liquid D'for a long time. You will be pickled. Then, the dye (treatment powder) d filled in the cylindrical member 11b is washed out by the solvent liquid D'which penetrates through a large number of punch holes and is mixed into the solvent liquid flow. The dye is prepared as a dyeing liquid (treatment liquid) D by being rubbed by a vortex flow generated by the circulation pump 1 on the downstream side or a rapid turbulent flow and dispersed or dissolved in various directions.

However, also in the first and second embodiments, it is not always necessary to use the powder bucket 11 when the dye (treatment powder) d is introduced, and as shown in FIG. Dye (treated powder) d may be put in 12 and thrown into the inlet 2. Alternatively, for example, a water-soluble sack F made of a material such as polyethylene oxide film may be used.
It is also possible to adopt a system in which the dye (processed powder) d is enclosed and thrown into the charging port 2.

Next, FIG. 5 shows a solvent liquid D ′ such as the circulating liquid passage 4.
In this example, the dye (treatment powder) d is introduced by using a cock or valve arranged at a location where the water rapidly flows. In this case, in order to prevent the inside of the cock and the valve from being contaminated. It is preferable to mount the guide tube G.

Although the examples and the method for adding the treatment powders described in the present specification are as described above, the present invention is by no means limited to the above description, and is included in the description of "Claims". Needless to say, various modifications can be made, for example, at the charging port 2 for charging the treated powder agent, the treated powder agent d that has been introduced due to swirling or turbulent flow in the solvent liquid D ′ is strongly stirred and diffused. Any location may be used, and a location indicated by a symbol A in the embodiment of FIGS. 1 and 2 is also suitable. The mechanism and the action of introducing the treatment powder d from such a location are the same as those of the present invention. It goes without saying that it belongs to the technical scope.

In the above embodiment, the jet dyeing machine and the beam dyeing machine are described as an example. However, the present invention is a cloth treating machine such as a conventionally known Jigger dyeing machine and a Wins dyeing machine, and further, a continuous dyeing machine. Needless to say, the present invention can also be applied to a continuous cloth processing machine for carrying out cloth processing, and it is also within the technical scope of the present invention to directly feed the processing powder to these cloth processing machines.

Further, although the present invention is applicable to a fabric treating machine at a low pressure and a normal pressure and a fabric treating machine at a high pressure and a high temperature,
When applied to a high-pressure and high-temperature cloth processing machine, the hatch 21 of the charging port 2 for charging the processing powder d and the drive source of the processing machine are electrically connected (not shown), and the hatch 21 is opened. It is useful for the safety of the operator to keep the drive source turned off when in the state, and this also belongs to the technical scope of the present invention.

[0024]

As described above, according to the present invention, the cloth treating powder is directly put into the solvent liquid by skillfully utilizing the vortex or the turbulent flow generated in the cloth treating machine, and the treating powder is easily treated. Since the treatment liquid is prepared by dispersing or dissolving the above, it is not necessary to separately provide a dissolving tank as in the conventional case, and it is not necessary to prepare the treatment liquid by the stirring liquid preparation device and carry it to the cloth treating machine. Therefore, it is possible to reduce the number of steps, shorten the processing time for preparing the treatment liquid, reduce the dissolution equipment, and save the space in the factory.

Further, according to the present invention, labor is not required for preparing and transporting the treatment liquid, and for cleaning the dissolution tank, the liquid preparation device, and the transport container, so that the labor cost can be significantly reduced and the treatment liquid can be transferred. It also eliminates the loss of the processing solution due to replacement, and the contamination and lost loss in the factory due to scattering during the preparation of the processing solution, which saves materials and helps to reduce the production cost.

Further, according to the present invention, the treating liquid can be prepared surprisingly quickly by directly pouring the treating powder into the fixed amount of the solvent liquid in the main body of the washing machine which is completely washed. Even when using a treating agent such as a dye or an acidic direct dye that easily causes hydrolysis, the time from the preparation of the treating solution to the treating of the fabric is extremely short, so that the fabric can be treated in a stable state. In addition, the concentration of the treatment liquid can always be adjusted according to the calculation, there is no variation due to individual differences among the persons in charge as in the past, and the purity of the treatment liquid is good, which contributes to stable and improved product quality. However, it is big.

As described above, according to the present invention, the fabric processing can be greatly rationalized, and it can be said that its industrial utility value is extremely large.
