Description

Dyeing apparatus of page using jigger type dyeing machine {DYEING OF INDIGO BY MODIFIED JIGGER}

The present invention relates to a dyeing apparatus of a side, and the dyeing, oxidation, and washing in the same dyeing machine are successively performed using an improved jigger type dyeing machine, so that a large amount of fibers can be processed simultaneously with a small number of people, It relates to a dyeing apparatus of the side using a jigger type dyeing machine to obtain a high-quality and industrialization of natural dyes.

The traditional method of dyeing is by fermenting raw greens, immersing a cloth in this solution, and then oxidizing it in the air. Looking more closely at this, cut the greens before flowering and put them in the poison, soak them with water for several days, Put the powder obtained by burning clam shell or oyster shell and stir vigorously up, down, left and right to get blue bubbles. Stir until the bubble mass becomes smaller and then leave it as it is, then separate it into a blue precipitate and a light brown liquid. It is removed, air oxidized and colored, and the process is repeated several times to obtain a dye of the desired color.

Indigo (indigo), which is a blue pigment of the green grass, is insoluble in water in the dyeing method using the above-mentioned green grass, but its precursor, indican, is present on the raw side as a glycoside of water-soluble glucose. I can do it. The indican is hydrolyzed and converted to indoxyl by the addition of alkaline lye, which is chemically unstable and oxidatively dimerizes in air to precipitate into a mixture of insoluble indigo and these intermediates. The mixture contains glucose, a reducing sugar, and when fermented, insoluble indigo is reduced to become water-soluble leuco indigo, which is oxidized and develops when left in air.

However, the above-described traditional method of dyeing the fabric is so cumbersome that it is difficult to obtain the dyeing of the desired color by repeating the process of immersing the cloth on the side of the cloth, rubbing it well, taking out the color in the air, and then dipping it again in the air. In addition, not only takes a lot of time and manpower, but because the process is all made by human hands, there is a problem that a lot of manpower and product quality is not constant.

In addition, since the traditional dyeing method has to repeat the immersion and color development a number of times in order to obtain the desired color, when the primary dyed cloth is immersed in the dye bath again, the colored indigo is reduced and becomes water-soluble so that the dye dissolves in the dye bath. Not only is it very inefficient, it is also prone to disproportionation during repeated oxidation and reduction.

An object of the present invention for solving the problems as described above is to seal the jigger type dyeing machine in a housing so as to maintain the airtight, the housing is connected to the nitrogen gas inlet / outlet and salt bath / flush bath salt inlet / outlet and flushing water By installing the opening / closing to be opened and closed, the dyeing, oxidation, and water washing can be performed continuously in the same dyeing machine, so that a large amount of fibers can be processed simultaneously with a small manpower, and even salts can be obtained. It is to provide a dyeing apparatus of the side using a jigger type dyeing machine.

An embodiment of the present invention for achieving the object as described above looks at with reference to the accompanying drawings.

1 is a view showing a dyeing apparatus of the side using a jigger-type dyeing machine according to the present invention, the dyeing apparatus of the side is a take-up roller (take-up roller) (1) (the cloth is wound around the outer circumference and rotated in the same direction) ( 2), a guide roller for guiding the cloth to be uniformly wound by the take-up rollers (1) and (2), and a salt bath / wash bath (5) installed so that the guide roller (3) is immersed during dyeing and washing with water. The housing 4 is sealed to maintain the airtightness of the jigger-type dyeing machine, and is installed through the housing 4 and controlled to be opened and closed by valves 6` and 7` so that nitrogen gas flows into the housing 4 /. Nitrogen gas inlet / outlet (6) (7) to be discharged, and installed through the housing (4) and connected to the salt bath / washing tank (5) constituting the jigger type dyeing machine and the valve (8`) (9`) Salt opening and closing (8) (9) and is controlled to open and close by allowing the salt solution to flow into and out of the salt bath / washing tank (5), Washing water inlet / outlet (10) (11) which is installed through the housing (4) so that the inside of the housing (4) can be washed with water, and controlled to be opened and closed by valves (10 ') and (11'). By oxidizing, rinsing, and washing in the same dyeing machine continuously, a large amount of fibers can be processed simultaneously with a small manpower, and even salts can be obtained, thereby enabling the advanced and industrialization of natural dyeings.

In addition, the guide rollers are additionally installed to be able to move up and down, and are dyed and washed at a position of 3, and at the time of color development, to be moved to a position of 3 '.

An embodiment of the dyeing apparatus using the jig-type dyeing machine configured as described above will be described below.

First, the cloth is wound on one side of the take-up roller 1, and the end of the cloth is wound on the other take-up roller 2 via the guide roller 3.

Then, the salt solution is introduced into the salt bath 5 through the salt solution inlet 8 to an appropriate level, and nitrogen is injected through the nitrogen gas inlet 6 until the air in the housing 4 is completely replaced with nitrogen, After moving the guide roller 3 downward so as to be located inside the salt bath 5, the cloth of the take-up roller 1 is removed by using a drive motor (not shown) of the take-up roller 2. When (2) is wound, dyeing occurs as the transition salt solution (13) passes. During dyeing, the valve 6` of the nitrogen gas inlet 6 is adjusted so that external air does not enter the inside of the dyeing machine, and nitrogen is appropriately injected.

When all of the transfer roller 2 is wound around, the drive motor (not shown) of the roller 1 is operated so that the dye can be rewound while rewinding from the transition roller 2 to the roller 1. This operation is repeated several times so that dyeing is carried out as required.

After the dyeing is completed, the guide roller is positioned at 3 'and the injection of nitrogen is stopped, the dyeing machine cap (4`) is opened to allow air to be injected into the dyeing machine, and the take-up rollers (1) and (2) are stained. Repeatedly drive it to make it sufficiently colored.

If the dyeing is insufficient, the guide roller 3 is lowered and the same operation as for dyeing is repeated. The deficiency of the saline solution at the time of dyeing continues to replenish through the saline inlet (8).

When the dyeing and coloring are sufficiently done, the remaining liquid is completely removed through the salt solution outlet 9, and the washing water is supplied to the washing tank 5 through the washing water inlet 10, and the guide roller is placed in the 3 position, and the take is carried out as in the case of dyeing. Water washing is performed while driving the up rollers 1 and 2 alternately. At the time of flushing, the valve 10 'of the flushing inlet 10 is appropriately adjusted so that the flushing water flows over the flushing tank 5 appropriately and flows out to the flushing outlet 11.

And, the dyeing results using the dyeing apparatus of the side using the jigger-type dyeing machine as shown in the following examples, in the following examples in the method of extracting indigo from the dry side filed by the applicant of the present application as the same By using the dye extracted by the same method, the same effect can be obtained by using the dye extracted by the conventional method.

<Example>

Fabric: Cotton 40S Plain weave 120g / m2, Width 60´, 100 YD

Side extract: 3Kg (10 times diluted with water)
