The contents of the claims of the present invention will be described in more detail and in detail through embodiments of the present invention. It is to be clearly understood that the embodiments described herein are not intended to limit the scope of the invention but that the invention is limited only by the claims set forth herein.

Side dyeing is carried out with a dye of the indoxyl state reduced by adding an alkali agent to induce hydrolysis of a substance called insoluble indanecarboxylic acid (Indantha) obtained by extracting from the papaya fruit. In addition to alkaline agents such as potassium carbonate, lye, caustic soda and sodium hydroxide, which are used as a natural fermentation agent, it is intended to provide an efficient production method of dyeing agent as well as dyeing quality by constituting a natural dyeing agent using malt as a main ingredient.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart showing a manufacturing process of a natural indigo dye according to the present invention, wherein 300 g of potassium carbonate and 10 liters of purified water are mixed with 100 g of powdered indanthrone to maintain the hydrogen ion concentration at pH 10 50 g of malt was added as an fermentation agent to the alkalized indahal solution and the pH of the solution was maintained at 30 to 35 ° C for 6 to 12 days at a pH of 10, (S20) for aging the dyestuff dyestuff by agitating the dyestuff dyestuff 1 to 2 times, and 9 L of purified water, 300 g of potassium carbonate, and 50 g of maltose were added to 1 L of the dyestuff dyestuff after the dyestuff dyeing step (S20) A fermentation dye step (S30) for forming an indanthrene dye by aging for 7 to 10 days until the color of the dye is expressed in deep fluorescent green by maintaining the temperature at 30 to 35 DEG C, ) To the indium dye 3 (S40) in which 0 L of water is mixed with 1000 g of potassium carbonate in 100 L of water and reduced at a temperature of 30 to 35 DEG C for 6 to 24 hours so that the natural dyeing cloth can be directly fed into the dyeing step (S40). .

The alkalizing step (S10) is a step of dissolving the insoluble indium in alkali by mixing 300 g of potassium carbonate and 10 L of purified water in 100 g of powdered indanthrone, and the amount of the potassium carbonate is initially 80 g When potassium carbonate is added at 80 g, the pH value of the dyestuff dyestuff is decreased to less than 10 in the fermentation process. Therefore, the efficiency of the fermentation operation is decreased due to addition of potassium carbonate. A problem arises. When the amount of potassium carbonate was varied from 80 to 400 g in the course of preparing the dyestuff dye according to the present invention, when the amount of potassium carbonate was 300 g as compared with 100 g of indanthrene and 10 L of purified water, The hydrogen ion concentration of the dyestuff dyestuff was maintained at 10 even when the addition of the alkali agent was not additionally performed. Therefore, it is appropriate to select the amount of potassium carbonate when reducing the dyestuff dyestuff according to the present invention to be 300 g as compared with 100 g of indanthrene and 10 liters of purified water. The reducing step is configured to reduce the indraumal solution prepared at the above ratio at a temperature of 30 to 35 ° C for 6 to 12 days. When the temperature is further increased to 40 ° C, the reduction time may be shortened to some extent .

In the step (S20), the alkali dyestuff solution is fermented by adding 50 g of maltol as an fermentation agent, and the malt is constituted by using commercially available maltose, thereby facilitating the composition of the dyestuff dyestuff In addition, the cost of materials is low, so the production cost is also lower than that of hydrous sulfite. The role of these malts is as follows. The microorganism bacteria are present in the microcrystalline powder itself, and the microbes contained in the microcrystals are promoted to promote the malt production. Malt contains starch, and starch is converted to sugar in the process of fermentation and used as a nutrient source. The fermentation is carried out at a temperature of 30 to 35 ° C. for 6 to 12 days. The fermentation site may be a vinyl house, a porch or a place warmed by direct sunlight, Is kept at a pH of 10 and agitated once or twice every 24 hours by aging the dirt dye. In this case, it is important to stir the dyestuff into the dyestuff to prevent air from penetrating into the dyestuff. To this end, a rotary member in the form of a screw or a propeller is provided under the container in which the dyestuff is fermented, So that the upper part of the container can be shielded, and the upper part of the container is made of transparent plastic material or glass so that the external heat source can be transferred to the dyestuff dye. It is preferable to configure it.

The fermenting dye step (S30) is a step of mass-producing the dyestuff dyestuff in a relatively short time by reconstituting the same amount of dyestuff dyestuff with a small amount of the fermented dyestuff dyestuff, 9 L of purified water, 300 g of potassium carbonate and 50 g of maltose were mixed with 1 L of the dye, followed by aging for 7 to 10 days until the color of the dye was expressed in a deep fluorescent green color at 30 to 35 ° C. do. At this time, in addition to the prepared indanthrene dye, potassium carbonate and malt are remineralized and fermented to make it possible to dye at the same concentration, but the fermentation material of the fermented indanthrene dye shortens the fermentation process at this stage . That is, in the process of fermenting 100 L of dyestuff dyestuff corresponding to 10 times of 10 L of dyestuff dyestuff, the fermentation time of 7 to 10 days, which is 6 to 12 days earlier than the fermentation time of 10 L of dyestuff dye composition It is possible to rapidly form a dye.

In addition, it can be seen that the fermentation period of 7 to 10 days in this step is shorter than 6 to 12 days in the fermentation period of the primer dyeing step (S20). In this step, 1 L of the 10% And the fermentation period is also shorter than the fermentation dye step (S20) since the fermentation process is preliminarily performed.

The dye finishing step S40 is a step of finishing the dyeing of the fermented indomannan dyestuff by mixing 30 liters of fermented dyestuff dyed dye with 30 g of potassium carbonate in 100 L of water at a temperature of 30 to 35 DEG C, To 24 hours, in which the dyestuff dye is directly added to the cloth dyeing. In order to prevent the dye from being reduced during the low temperature season in this step, it is also possible to provide the dye directly to the outer surface of the container so that the fermentation temperature is maintained evenly.

As a result of the above procedure, natural scintillation agent is completed and any one of yogurt 195 mL, rice wine 200 mL, yeast 5 g and starch syrup 5 g, malt 50 g, and madder 50 g can be selected to replace the malt used as the fermentation agent It is possible. However, we note that malt is easiest to ferment in terms of fermentation function and cost.

Now we want to describe how to dye cotton fabric with this dyestuff dye.

FIG. 2 is a flowchart showing a natural dyeing method using an Indoor natural dye according to the present invention. (P10) for immersing the cloth as a salt solution in purified water for 30 seconds to 5 minutes to moisten the cloth without adsorbing the air, and 1000 g of potassium carbonate in 100 L of purified water to adjust the hydrogen ion concentration to 9.5 to 11 A dyeing dye step (P20) in which 30 L of the reduced and fermented indanthra dyestuff is mixed with 100 L of the alkaline purified water and aged at 30 to 35 DEG C for 6 to 24 hours to form an indium salt solution; A dyeing step (P30) of dyeing 6 to 12 yards of cotton fabric by immersing the fabric in a salt solution for 5 minutes and then performing daylight drying for 1 to 3 days, wherein the dyeing and daylight drying are repeated 1 to 2 times; Drying is carried out for 4 to 6 hours and then immersed in water, followed by 3 to 4 times of washing with sunlight, and the pH of the solution is adjusted to 5 to 6 with vinegar, followed by immersion in the cloth for 20 to 30 minutes Three to remove alkali (P50) for immersing the cleaned cloth in water heated to 70 to 80 DEG C for 10 to 30 minutes to remove alkali components, a finishing step (P60 ); Shows that the dyeing method is constituted.

Wherein the dyeing step of the indigofera pigment contained in the indoors is carried out by immersing the cloth as a water-borne leuco dye in water for 30 seconds to 5 minutes by immersing the cloth as a phytate in purified water for 30 seconds to 5 minutes, Indigo is not chemically bound to fibers, but when the leuco indigo is oxidized again to indigo form and then intervened in the void space of the polymer chain forming the fiber, the relatively large indigo molecules can not escape from the space When the air is contained in the hollow space of the polymer chain, a space in which the Ryuko Indigo can enter can not be secured. In order to prevent this phenomenon, in this step, the fabric is moistened with water beforehand so that air does not permeate the cloth. Also, the polymer structure of cotton fiber is 1,200 ~ 1,300 glucose units are separated from other chains, When wetted, the hydrogen bonds are loosened so that the chains are farther away, so that the leuco indigo particles penetrate into the spaces between the separated chains and dyeing is easily performed.

In the dyeing step (P20), 1000 g of potassium carbonate and 30 to 40 L of reduced and fermented indanyl dye are mixed with 100 L of purified water and aged at 30 to 35 DEG C for 6 to 24 hours to adjust the hydrogen ion concentration to 9.5 to 11 The amount of potassium carbonate corresponds to 100 g of purified water per 100 L, which is reduced to 1/3 from 300 g of potassium carbonate in the dyestuff dyestuff composition. The reduction of this step is to preliminarily raise the hydrogen ion concentration of the purified water diluted in the reduced and fermented indanthrene dye to alkalize it, and may be less than the amount of potassium carbonate used in the dyestuff dyestuff composition If the amount of potassium carbonate is used in excess, the alkaline removing process, which is a washing process of the flocked cloth, may take a long time. The blending ratio of the purified water and the dyestuff dyestuff may be 100: 30-100: 40, and the amount thereof may be adjusted according to the indigo-light-emitting method or the usage or consumer's preference. The higher the fermentation temperature, the shorter the fermentation time and thus the preparation time of the slurry, but the temperature may be maintained at a minimum of 30 ° C in order to reduce the energy required for maintaining the temperature.

The dyeing step (P30) is performed by dipping a cloth composed of 6 to 12-yard cotton fabrics in fermented indra saline solution for 5 minutes and then performing day light drying for 1 to 3 days. The dyeing and daylight drying are repeated 1 to 2 times It is preferable that when the cloth is immersed in the slurry, the cloth and the upper layer of the slurry collide with each other in the immersion process so that the air does not penetrate into the slurry. For this purpose, rather than pushing the cloth down vertically downward to sink into the salt solution, put the cloth on the top of the salt solution, wait until the salt solution begins to be dyed to the surface of the cloth to some extent and then lightly press the cloth two or three times. Do not occur. After 5 minutes of primary staining is completed, daylight drying is performed outdoors so that the indigo is expressed in the blood spots, and then the spots are repeatedly dipped in the saline solution to increase the sharpness of the color. In addition, by adding 4.5 to 6 L of reduced and fermented indanthrene dye according to the present invention to the salt solution used for staining the cloth, the dyeing process can be configured so that the salt solution can be reused for staining the cloth. From 4.5 to 6 liters of the dyestuff dyes, 45 to 60 g of indanthrene are mixed with 135 to 180 g of potassium carbonate, 22.5 to 30 g of maltose and 4.5 to 6 liters of purified water to prepare the Indram natural dye. By adding only a small amount of dye to the used salt solution as described above, it is possible to shorten the preparation period of the salt solution and increase the reuse rate of the dye, thereby improving the productivity and the working efficiency of the dyeing operation.

The washing step (P40) is carried out for 3 to 4 times by immersing in water after drying for 4 to 6 hours, then washing with sunlight and washing again, adjusting the pH to 5 to 6 with vinegar, It would be desirable to perform a cleaning for removing the alkali component for 30 minutes. The composition of the vinegar is such that the vinegar circulated in the market is diluted to a pH of 5 and the fabric is neutralized to some extent through vinegar and then washed with cold water to remove the alkali component again. The drying and washing may be performed several times or the vinegar water immersion process and the hot water washing process may be repeatedly performed to promote the neutralization of the alkali included in the cloth.

In the hot water washing step (P50), yellowish hues other than tricolor (blue) are expressed in the swished cloth through day light drying. The step of soaking the cloth in water heated to 70 to 80 DEG C for 10 to 30 minutes, The alkali component contained in the cloth is finally removed and a gap between the fiber textures is opened through the hot water to desorb the foreign matter adhering to the cloth and the pigment decomposed in the yellow color during the dyeing process and the drying process. In addition, a cloth is fixed to a plurality of rods extending radially from the center of the container in which the hot water is formed toward the inner circumferential surface of the container, a rotating shaft is provided at the center of the container, So that the impurities contained in the cloth, the alkali component and the pigment decomposed in yellow are more effectively removed.

The finishing step (60) is performed by drying the cloth which has been dried and washed in the washing / hot-water washing step (P40, P50) by daylight drying outdoors in the sunlight.

As described above, the art of dyeing dyeing method according to the present invention has been accomplished, and the following examples are intended to further illustrate and clarify the present invention by demonstrating the effectiveness of dyestuff dyeing method and dyeing method using same.

This example is intended to optimize the range of fermentation temperatures involved in the preparation of dyestuff dyes. The basic composition of the experimental group and the control group was the same as that of the dyestuff dyestuff prepared above, and the composition of the fermentation temperature was classified into a primary dye and a fermented dye phase (S20, S30) Respectively.

The composition of primary dye fermentation experiment groups 1 to 6 was prepared by mixing 300 g of potassium carbonate and 10 L of purified water with 100 g of indomethacin and alkalizing them, and then adding 50 g of maltose as an fermentation agent. The secondary fermentation experiment groups a to f Was prepared by adding 9 L of purified water to 1 L of dyestuff dyestuff prepared in Experimental Group 1, and aging by mixing 300 g of potassium carbonate and 50 g of maltose.

As shown in Table 2, the fermentation period is gradually shortened as the fermentation temperature is increased. However, as the fermentation temperature increased, the change in the shortening of the fermentation period gradually decreased. As a result, the fermentation period of the experimental group 5 and the experimental group 6 was the same as that of both the fermentation period of 6 days, The fermentation process tends to be delayed by more than 2 times. Therefore, the range of the primary dye fermentation temperature is set to 30 ° C. and the maximum temperature is 35 ° C. by applying the temperature range of Experiment 3, 4 and 5 .

Table 3 below shows the fermentation time of the experimental groups a to f following the fermentation of the fermented dye, and the appropriateness of fermentation was judged by the same method as above.

As shown in Table 3, the higher the fermentation temperature, the shorter the fermentation period. However, the shortening of the fermentation period is not substantially different between the experiment group "e" and the experimental group "f". In the experiment group "a" and the experimental group "b", the fermentation period exceeds 10 days. It is intended to employ the fermentation temperature of 30 to 35 占 폚 corresponding to the composition of Experiments c to e as the secondary fermentation reference temperature of the present invention.

In this embodiment, it is intended to optimize the content of potassium carbonate, which is an alkaline agent used in the present dyestuff dyestuff. In general, potassium carbonate is firstly used in the initial reduction process and is used for secondary addition to increase the pH value of the fermentation process after fermentation. However, the present invention proposes a blending ratio of potassium carbonate that allows the fermentation process to be smoothly performed without further addition of potassium carbonate during the fermentation process.

The amount of potassium carbonate added in the alkalizing step S10 is different as shown in Table 4. In the primary dye step S20, 50 g of malt was batch-mixed and then fermented at a temperature of 35 ° C for 12 days Experimental groups 1 to 7 according to the present embodiment were constructed.

As a result of the above experiment, the change of the hydrogen ion concentration measured in the fermentation dye step (S20) of each experimental group was derived as shown in Table 5 below. In order to measure the change in the hydrogen ion concentration of the dye in the absence of the addition of the alkali agent, potassium carbonate as the alkali agent was not added at all during the measurement of the hydrogen ion concentration shown in Table 5.

As shown in Table 5, in the experimental groups 1 to 5, the hydrogen ion concentration was reduced to less than 10 on day 7, indicating that the acidification progressed to some extent. On the contrary, the experimental group 6 and the experimental group 7 maintain the hydrogen ion concentration at the 7th day, and it can be inferred that the dye can be fermented without addition of potassium carbonate while maintaining the dye reduction. In addition, it was judged that there was no difference in the alkali persistence according to the amounts of potassium carbonate in the experimental group 7 and the experimental group 6. Therefore, in order to reduce the material cost, 300 g of the potassium carbonate, which is applied to the experimental group 6, As a mixing ratio of potassium carbonate to be added.

This example is intended to optimize the composition of the fermentation agent used in the fermentation process of dyestuff dyes.

As shown in Table 7, the highest values were recorded in the order of 5, 3, 4, 2, and 1 in the color groups and the dyeing concentration, respectively. Experimental group 5 with the highest values showed the highest dyeing quality The madder was determined to be maltose of experimental group 3 which is easy to purchase and excellent in durability because it is difficult to buy it because it is difficult to buy it because it is not imported into traditional medicine. Accordingly, it is considered that it is most appropriate to prepare the dyestuff in a blending ratio of 50 g of malt compared to 100 g of indanthrene, using malt as the constituent of the fermentation agent in forming the dyestuff dye according to the present invention.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings. It is to be clearly understood that the foregoing embodiments are merely illustrative and that those skilled in the art will be able to make various modifications and other equivalent embodiments.
