Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dyeing device for indigo kasuri, and more specifically, the present invention relates to a dyeing device for indigo kasuri, and more specifically, the present invention relates to a dyeing device for dyeing indigo kasuri, and more specifically, the present invention irradiates ultrasonic waves to bamboo mats in a dye bath to indigo dyeing.
This invention relates to an ultrasonic automatic dyeing device that is capable of uniformly dyeing indigo in medium color.

[Conventional technology]

For example, in the dyeing technique of authentic Oshima Tsumugi indigo textiles, in order to perform indigo dyeing by partially resist-dying the threads, 16 silk threads (fiber aggregates) are hardened with glue, and then woven and tightened with gas cotton threads for resist-dying. Make a section and dye it.

When dyeing indigo kasuri, it is necessary to maintain the reduced state of the indigo, and it is not possible to dye it by vigorously rubbing it into the indigo or increasing the temperature of the indigo solution. This is because vigorous operations in the indigo promote oxidation of the reduced indigo, and high liquid temperatures cause the highly alkaline indigo to embrittle the silk.

Therefore, in the dyeing of authentic Oshima Tsumugi indigo kasuri, a manual method has traditionally been used in which the indigo kasuri is gently immersed in indigo, and the indigo is repeatedly squeezed with a pull-up roller to develop the color.

[Problem that the invention seeks to solve]

However, in the conventional dyeing method as mentioned above, the penetration of the dye solution during dipping is insufficient, so in order to completely dye the fiber aggregate to the center, it is necessary to operate the roller squeezing during dipping in the indigo solution. This process is repeated many times and requires a lot of effort. In addition, as a result of repeating indigo dyeing many times in order to dye the surface and center uniformly, indigo kasuri could only be dyed dark blue. There was a desire to make the characteristic of indigo dyeing, which can originally dye a rich variety of beautiful blues ranging from light to deep colors, to dyeing indigo kasuri, and to diversify products by adding new products such as light and medium-colored indigo kasuri.

The present invention has been made to solve the above-mentioned conventional problems, and aims to provide a new automatic ultrasonic dyeing device that can dye indigo kasuri in light to medium colors and with good leveling properties. be.

[Means to solve the problem]

To solve the above problems, the dyeing device of the present invention has a dyeing tank formed in a donut shape, in which ultrasonic transducers are arranged equidistantly on both sides of the tank, and a dyeing tank that maintains the properties of the indigo liquid constant. A fermentation adjustment tank that is equipped with a meter and a slow stirrer that can be used for measurement control and supplies indigo liquid to the dyeing tank, and a hanging metal fitting for transporting and airing the kasuri kasuri into the dyeing tank. A hanging type automatic transfer mechanism that raises and lowers and rotates the dyeing tank, a squeezing mechanism that removes excess indigo liquid adhering to the Kasuri mat, and a dyeing, squeezing, and airing process to maintain the dyeing concentration to a predetermined dyeing density. The structure is characterized by comprising a control device that controls the automatic transfer mechanism and the squeezing mechanism so that the dyeing process is automatically repeated a plurality of times until the staining process is completed.

For example, the kasuri kasuri is attached to this device via a J-shaped hanging metal fitting, and a control device that performs sequence control performs each dyeing process of dyeing, squeezing, and air ring until the kasuri kasuri reaches a predetermined density. The process is automatically repeated repeatedly, making it possible to quickly perform a predetermined dyeing process without requiring any manual effort or skill.

Ultrasonic generators are installed equidistantly on both sides of the donut-shaped dyeing tank of the present invention, which generates a uniform ultrasonic sound field in the dyeing tank, and dyes the dye through a J-shaped hanging metal fitting. By uniformly irradiating the Kasuri mats with ultrasonic waves as they are developed and transferred into the liquid, uniform diffusion of the dye into the Kasuri mats is efficiently promoted. By squeezing the Kasuri mats to which the dyeing liquid has been attached in this way using the above-mentioned hanging type automatic transfer mechanism and squeezing mechanism, and then air-ringing them using the hanging type automatic transfer mechanism, the dyeing reaction promoting effect of ultrasonic waves makes it possible to achieve a process that was previously impossible. It becomes possible to dye evenly in warm light and medium colors without uneven dyeing. In addition, the effect of ultrasonic waves makes it possible to dye indigo in light and medium colors with good ground separation.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a schematic plan view showing the overall structure of the dyeing apparatus of the present invention, and FIG. 2 is a side view of FIG. 1.

A dyeing tank 1 formed in a donut shape and a cylindrical fermentation adjustment tank 2 inside the dyeing tank 1 together constitute a tank portion of the dyeing apparatus of the present invention.

The dyeing tank 1 has ultrasonic transducers 3 arranged equidistantly on the inner and outer surfaces 1a and 1b and in a staggered manner on both sides of the tank.
The apparatus is equipped with an ultrasonic transducer 3 that uses electric energy from an ultrasonic transmitter 6 to irradiate ultrasonic waves onto the Kasuri Kasuri 5, which is the object to be dyed, while immersing it in dyeing. The above configuration makes the ultrasonic sound field in the dyeing tank 1 uniform and eliminates uneven dyeing. The fermentation adjustment tank 2 is equipped with a stirrer 4 in the center, which gently stirs the fermentation,
While circulating the liquid through the filter 12 with the fermentation adjustment tank circulation pump 13, the thermometer 14, PH meter 16,
The properties of the indigo dye are adjusted while monitoring the temperature, PH, ORP (oxidation-reduction potential), conductivity, etc. using an ORP meter 15, etc., and the properties of the indigo dyeing solution are maintained constant.

The Kasuri mat 5 is attached to the metal fitting 1 of the hanging type support mechanism as described below.
8, and is rotated and raised and lowered relative to the dyeing tank 1 by an automatic transfer mechanism. That is, the automatic transfer mechanism consists of a Kasuri Kasuri moving machine 7 and a Kasuri Kasuri lifting machine 8, and a hanging type support mechanism is rotatably supported at a position above the above-mentioned fermentation adjustment tank 2. Post 1 installed in the outside position
A kasuri kasuri mat moving machine 7 is provided along the line 9 so as to be movable up and down. Therefore,
The kasuri kasuri 5 being dyed is transferred to the dyeing tank 1 by the kasuri kasuri moving machine 7.
The kasuri kasuri (kasuri kasuri) lifter 8 moves the kasuri kasuri (kasuri kasuri) up and down into the air at the time of squeezing and airing.

In addition, a squeezing roller 9 is installed on the frame of the hydraulic unit 11 outside the dyeing tank 1, and is movable back and forth and up and down. The indigo liquid adhering to the Kasuri mat 5 after being immersed and dyed by ultrasonic waves from step 3 is squeezed out. All of the above-mentioned elements are automatically operated by a control device 10 incorporating a sequencer.

Next, the operation of the dyeing apparatus configured as described above will be explained.

Control signals are input to the Kasuri Kasuri Kasuri elevator 8, Kasuri Kasuri moving machine 7, and ultrasonic vibrator 3 in the dyeing process order programmed in the control device 10, and the Kasuri Kasuri 5 is immersed and dyed. After dyeing, the kasuri kasuri 5 is pulled up into the air and the indigo liquid is removed by a squeezing roller 9, and then expanded in the air, and the dyeing is fixed by airing. By repeating this process, uniform dyeing of light to medium colors becomes possible, and the dyeing method will be described in detail below.

First, as a hanging support mechanism for the kasuri mats 5, which are objects to be dyed, the metal fittings 18 of the mounting part are connected in units of a plurality of pieces at the upper part with equally spaced strips of cloth, and at the lower part there are each a pair of J-shaped kasuri mats. It has a wire for hanging bamboo mats. If the Kasuri Kasuri 5 is directly supported by a metal fitting, it will be difficult to squeeze the Kasuri Kasuri with a roller, so a string of a certain length is attached to the Kasuri Kasuri and is hung on a J-shaped wire to attach the Kasuri Kasuri.

Next, the fermentation liquid that has been indigo-finished in advance is transferred to the fermentation adjustment tank 2, and while circulating the liquid through the filter 12 with the fermentation adjustment tank circulation pump 13, the thermometer 14,
Temperature, PH, using PH meter 16, ORP meter 15, etc.
Adjust the properties of the indigo liquid while monitoring ORP (oxidation-reduction potential), conductivity, etc. After the adjustment, the indigo liquid is transferred from the fermentation adjustment tank 2 to the dyeing tank 1 through the filter 12 by a transfer pump 17.

The Kasuri Kasuri 5 attached to the support fitting 18 is lowered by the elevator 8 and is expanded and immersed in the dyeing tank 1. At the same time that the Kasuri Kasuri moving machine 7 starts rotating in the forward direction, the electrical energy supplied from the ultrasonic transmitter 6 is converted into mechanical vibration energy by the ultrasonic vibrators 3 provided on the walls 1a and 1b on both sides of the dyeing tank 1. The converted light is irradiated onto the Kasuri Kasuri mat 5, and dyeing by dipping is started.

When a predetermined dyeing time has elapsed, ultrasonic transmission by the moving machine 7 and the ultrasonic transducer 3 is stopped, and the dye is lifted into the air by the elevator 8. Here, the unfolded Kasuri Kasuri 5 is bundled by the moving machine 7 into four equal parts above the dyeing tank, including the position where the squeezing roller 9 is located.

At this point, the hydraulic unit 11 starts and the squeezing roller 9
The frame provided with the kasuri mats moves forward and rises, and at a fixed position, the rollers 9 hold the bundle of kasuri mats 5 so as to sandwich them from the front and back.

Subsequently, the frame begins to descend and removes the indigo dye adhering to the Kasuri mat 5 while sequentially squeezing it from top to bottom.

At the lower limit position where the squeezing is completed, the roller presser returns, and after the frame retreats, the moving machine 7 rotates 1/4 forward, and moves on to the squeezing process of the next bundle of Kasuri mats.

The above-mentioned squeezing process is repeated four times to finish squeezing all the kasuri mats 5, the hydraulic unit 11 stops, and the bundled kasuri mats 5 are unfolded by the moving machine 7 in a 1/4 reverse direction.
The unfolded Kasuri Kasuri is rotated in the normal direction again by the moving machine 7, and is air-ringed while rotating in the air for a certain period of time.

With the above steps, all steps for one dip dyeing are completed. If the dyeing density is too low with one dyeing, it is desirable to repeat this step multiple times for dip dyeing.

In the above embodiment, the indigo dyeing of Oshima Tsumugi was described, but the range of application is wide and it can be effectively used for dyeing other fiber aggregates. For example, it has been confirmed that even thick fabrics such as canvas, woven embroidery, terry cloth, jersey, etc. can be dyed evenly to the center of the fabric. Furthermore, this device can be applied not only to fermented indigo liquid but also to industrial reduction baths.

〔Effect of the invention〕

As explained above, according to the ultrasonic automatic dyeing apparatus of the present invention, the Kasuri Kasuri mat is transferred into the dyeing tank by the hanging type automatic movement mechanism, and the ultrasonic wave is applied evenly to both sides formed in a donut shape. The dyeing solution can be uniformly applied to the kasuri kasuri in a dyeing tank equipped with a vibrator, and the kasuri kasuri with the dyeing solution evenly adhered to it is squeezed and squeezed by the above-mentioned hanging type automatic transfer mechanism and squeezing mechanism. By air-ringing and repeating these steps, it is possible to uniformly dye the Kasuri mat in dark, medium, and light colors, making it possible to create new products that have never existed before.

Further, according to the present invention, since the repetition of the above steps is automatically performed by the control device, a great effect can be obtained in that manual labor is reduced.
