DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyeing apparatus for continuously dyeing cloth such as cloth, paper or leather using a high frequency wave used in a microwave oven or the like.

[0002]

2. Description of the Related Art Conventionally, dyeing apparatuses include a discontinuous method, a semi-continuous method and a continuous method.
Apparatuses suitable for the respective dyeing conditions and properties of the material to be dyed have been developed. FIG. 5 is a schematic view for explaining the concept of a conventional dyeing by a batch method which is a discontinuous method. In FIG. 5, reference numeral 1 denotes an immersion tank into which the dye solution 2 is placed,
3 is a heater for heating the dyeing liquid 2, 4 is a stirrer for making the temperature of the dyeing liquid 2 uniform, and 5 is a temperature sensor for detecting the temperature of the dyeing liquid 2. The control unit 6 controls the heater by turning on and off the power supply based on the value detected by the temperature sensor 5. Reference numeral 7 denotes a partition plate which partitions the article 8 so as not to come into contact with the heater or the stirrer 4 when the article 8 is immersed in the immersion tank 1. There is also a method of heating from outside the immersion tank using a gas instead of a heater as a heating source.

[0003] In the above construction, a dyeing material 8 from which the glue, impurities, and deposits on the fiber surface are removed, that is, a so-called white cloth, is immersed in the immersion tank 1 for dyeing. In dyeing, it is necessary to improve the concentration and temperature distribution of the dyeing liquid 2 and to improve the contact between the object 8 and the dyeing liquid 2. Therefore, the mixture is agitated by the stirrer 4 and immersed for 2 to 3 cycles in one cycle of 20 to 60 minutes. Alternatively, the contact between the dyeing liquid 8 and the dyeing liquid 2 is improved by moving the dyeing object 8 up and down or swaying left and right after immersion. In particular, in an apparatus that does not use the stirrer 4, it is necessary to pay sufficient attention to this point. In addition to directly heating the dyeing liquid 2 in the immersion tank 1, a heating tank is provided separately from the immersion tank 1, and the dyeing liquid 2 is heated in the heating tank to circulate between the immersion tank. Is also good. In addition, the temperature of the dyeing liquid 2 varies depending on the type of the material to be dyed 8 and the dyeing agent,
85-95 ° C for normal dyes, 40-6 for natural dyes
Generally, it is carried out at 0 ° C. In this dyeing step, temperature control is particularly important, and there is a temperature specific to the dye depending on the dye used. If the temperature deviates from this temperature, the color of the dyed product will change, and if it is dyed continuously, it will cause color unevenness.

FIG. 6 is a schematic diagram for explaining the concept of the conventional dyeing by the continuous method. In FIG. 6, 9 is the dyeing solution 1.
Reference numeral 11 denotes a roller provided in the immersion tank 9 and reference numeral 12 denotes a roller provided in the last part of the immersion tank. 13 is a circulation pump for circulating the dyeing liquid 10, and 14 is a heating unit for detecting the temperature of the refluxed dyeing liquid 10 and heating it to a predetermined temperature. There is also a continuous dyeing apparatus of the type in which the dyeing liquid 10 is heated and stirred in a dipping tank without reflux. Reference numeral 15 denotes a material to be dyed.

[0005] In the above-described configuration, the object 15 is dyed through a plurality of rollers 11, and finally passed between the rollers 12, squeezed, and then goes to the next step. Staining conditions and the like are performed according to a continuous dyeing apparatus.

After dyeing, excess dye attached in the dyeing process is washed and removed by washing with water, the dyed color is fixed so that it does not fade during use or by ultraviolet rays, and then washed with water and dried to obtain a fabric. Had been stained.

[0007]

As described above, in the dyeing apparatus, it is necessary to heat the dyeing solution to a constant temperature, and an electric heater or a gas is generally used as a heating means. However, it has been very difficult to maintain a constant temperature using a heater. That is, in the case of the non-continuous dyeing apparatus, when the object 8 is immersed in the immersion tank 1 after the temperature is fixed, the temperature of the immersion tank 1 is reduced, and the heater is energized. At this time, even if the stirrer 4 is operating, the object 8 to be immersed in the immersion tank 1 does not stir well, and the dyeing liquid near the high temperature heater becomes high. Furthermore, since the inside of the dyeing object 8 is not stirred, there is a problem that the temperature difference between the outside and the inside becomes large. If the temperature is increased slowly in order to prevent this, a new time will be required. This is the same even when dyeing is performed by gradually raising the temperature from room temperature to a predetermined temperature.

When a heater is provided outside the immersion tank to heat the liquor, the liquor is indirectly heated through the outer shell forming the immersion tank. Therefore, when the temperature of the dyeing solution reaches a predetermined temperature, the temperature of the outer shell is higher than the temperature of the dyeing solution even when the power supply of the heater is opened, so that the problem that the dyeing solution gradually rises. Occurs other than In order to prevent this, if the temperature of the dyeing solution and the outer shell are made almost the same and heating is performed slowly, the same problem as described above that it takes too much time occurs. This was the same even when gas was used as the heat source.

When the dyeing liquid 10 is circulated by the continuous dyeing apparatus, the object 15 in the immersion tank 11 becomes an obstacle, and the circulation of the dyeing liquid 10 is not evenly and uniformly circulated in the immersion tank 11. However, there is a problem that it is difficult to make the temperature uniform because the flow path is biased and unstable. In addition, since it takes a long time to dye, there is a problem that the apparatus becomes large when trying to increase the processing amount.

The present invention solves the above-mentioned conventional problems. In continuous dyeing of an object to be dyed, a high-frequency irradiation which can easily maintain a predetermined temperature and can be dyed in a shorter time than the conventional dyeing time. It is an object of the present invention to provide a dyeing method using the method and a dyeing apparatus using the method.

[0011]

The high frequency heats the inside of the substance, and the output can be easily controlled, so that the temperature of the dyeing solution can be easily controlled. In addition, when high-frequency irradiation is performed on the object, the polymer constituting the object is loosened,

DESCRIPTION OF THE PREFERRED EMBODIMENTS A feature of the present invention is that a method of irradiating high-frequency power (hereinafter referred to as high-frequency irradiation) used in a microwave oven or the like is used as a means for dyeing an object to be continuously transferred. The use of high-frequency irradiation produces the following effects.

As for the temperature control, since the inside can be heated at a high frequency, the inside of the article to be immersed in the immersion tank can also be easily heated. Since output adjustment is easy, temperature control can be performed within a narrow range, and temperature fluctuation can be reduced. There is an effect that only the object to be heated inside can be heated through the container.

As for dyeing, when a high frequency is irradiated, the polymer constituting the fiber is polarized. This polarization changes polarity alternately according to the electric field. Therefore, the movement of the polymer becomes intense, and a gap is formed between the polymers, and the dye becomes easy to enter into the polymer.Because the movement is intense, a new dye solution containing the dye is constantly supplied from another source, so that dyeing is performed. It can be done easily in a short time. In addition, high frequency is considered to easily and firmly bond the polymer and the dye because the energy is high.

The high-frequency irradiation can be controlled by a method in which the high-frequency output from the high-frequency generator is kept constant and the output is controlled by the average power within a certain period of time. There is a method in which the control is performed based on the level of the high-frequency output from the means. In experiments conducted prior to the present invention, it was found that what was required for staining was the high-frequency irradiation time and not the high-frequency output. Therefore, in this embodiment, any high-frequency irradiation method may be used.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, regarding a dyeing apparatus using a method using high-frequency irradiation.

(Embodiment 1) FIG. 1 is a sectional view of a dyeing apparatus using high-frequency irradiation in Embodiment 1 of the present invention. In the figure, reference numeral 16 denotes a dyeing apparatus main body, which includes a heating chamber 17 for performing dyeing therein, and a power supply section 18 provided above and below the heating chamber 17. Reference numeral 20 denotes a radio wave leakage prevention mechanism provided at the entrance and exit of the article 19 provided before and after the heating chamber. Reference numeral 21 denotes an immersion tank filled with a dye solution 22 for dyeing the article 19 accommodated in the heating chamber, and is made of a material made of glass, porcelain, synthetic resin, or the like that transmits high frequency. Reference numeral 23 denotes a roller provided in the immersion tank 21. Reference numeral 24 denotes a liquid storage tank having cooling means for adjusting the amount of the dye solution in the immersion tank 21 and controlling the temperature of the dye solution 22 in the immersion tank 21, and the dye solution 22 is immersed by a circulation pump 25 through a pipe 26. It circulates between the tank 21 and the liquid storage tank 24. Reference numeral 27 denotes a high-frequency generator such as a magnetron provided in the power supply unit 18, and supplies high-frequency power to the heating chamber 17 via a waveguide or directly. At this time, the high frequency is supplied while being stirred by the rotating stirrer 28 driven by the motor. The radio wave leakage prevention mechanism 20 has a stainless steel screw having a length of about 1/4 wavelength and is fastened to a metal wall with a nut, and conforms to US Pat. No. 4,182,946.

The liquid surface is irradiated with the high frequency from the power supply units 18 provided above and below the first dyeing liquid 22 by a high frequency generating means 27 while stirring the liquid with a stirrer 28 so that the temperature of the dyeing liquid 22 is reduced.
Is heated to a predetermined temperature suitable for dyeing. In the high frequency irradiation, almost all of the irradiation energy is absorbed by the dye solution 22, so that the temperature of the dye solution 22 can be quickly raised, and the high frequency output can be easily changed, so that fine temperature control is possible. In the high-frequency heating, the inside of the liquid can be heated. However, the stirring can be performed more uniformly by providing a stirring means. After this,

Further, a heating means is provided in the liquid storage tank 24, and when the temperature of the dyeing liquid 22 is raised, heating by this heating means and high-frequency heating can shorten the temperature rising time.

In this manner, the forward radio wave leakage prevention mechanism 2
A long and continuous object 19 inserted from the object insertion opening having 0 is subjected to high frequency irradiation while passing through the immersion tank 21 provided in the heating chamber 17 and is dyed in a short time to prevent radio wave leakage. The material is continuously taken out of the dyeing apparatus main body from the material taking-out port having the mechanism 20, and the process proceeds to the next step.

A light fastness test was performed on the dyed article dyed by the above method. The test was performed using a xenon lamp-type weathering tester, and was performed continuously for 24 hours in an environment of 63 ° C. and 50% humidity at an output of 1000 W at which a spectrum close to that of natural daylight was obtained. The test results showed excellent fading properties comparable to or better than those obtained by dyeing by the conventional method without high-frequency irradiation.

As described above, according to the method of this embodiment, the temperature of the immersion tank 21 can be easily controlled. In addition, the dyeing by high-frequency irradiation can be performed in a very short time, and the required time is a fraction to several tenths in the case where no high-frequency is used.

FIG. 1 shows a case in which four high-frequency generating means are provided in each of the upper and lower portions with respect to the traveling direction of the article 19, but the present invention is not limited to this. May be provided, or more magnetrons may be provided. Further, a plurality of objects may be provided in a direction perpendicular to the traveling direction of the article 19. In any case, the number and arrangement of the high frequency generating means may be designed in accordance with the dyeing apparatus. Further, the control of the high frequency generating means 27 may be performed individually.

At this time, the temperature of the object 19 is controlled by controlling at least one of the output of the high-frequency generator 31 and the moving speed of the object 19 so that high-frequency irradiation can be secured for a predetermined time. The high-frequency irradiation time varies depending on the type of the object 19 or the dyeing solution 22, but is only required to be about several tens of seconds to several minutes, and it is only necessary to take several tenths to several tenths of the time when no high-frequency irradiation is used.

If a partition plate 35 having an opening 34 for passing the article 19 is provided between the immersion tank 22 in which the article 19 is immersed and the dyeing section 29 for high-frequency irradiation, the high-frequency wave is applied during high-frequency irradiation. Since it is difficult to diffuse, the heating efficiency is improved.
