Description

  The present invention relates to a dyeing method using an amber dyed cloth, and more specifically, natural dyeing is carried out on an amber dyed cloth dyed with amber astringency using natural plant materials Ai, Gardenia, and Cochineal as a dyeing agent. In addition, the present invention relates to a dyeing method using a koji-dyed cloth that can express natural fibers with various colors and good ventilation.

In general, dyeing using strawberry astringent is one of the traditional craft dyeings named Jeju and centered on Jeju Island. A dyed product is obtained by developing the color by exposure to sunlight for months.
The koji-dyed cloth refers to a cloth that is colored brown by repeating the process of dyeing and drying koji astringent on a natural raw koji using the method for dyeing koji astringent.

In the color development process in the amber astringent dyeing as described above, the tannin component in the blue cocoon is dyed on the fiber, and the tannin molecule is slowly polymerized by the energy of sunlight, thereby producing a reddish brown color.
Dyeing with a tannin component will improve the breathability of the fabric, maintain the color for a long time, and become resistant to moisture.

  However, the longer the time of exposure to sunlight, the higher the molecular weight of tannin and the deeper the color, so it takes a long time to obtain fibers of the desired color as well as a large amount of labor. is required.

  In addition, the disadvantage of strawberry astringency dyeing is that when the tannin component is the most, that is, when it is blue candy, it is necessary to collect the dyeing material, and it takes a long time from dyeing to coloring, but it rains in the middle of coloring Sometimes the color does not develop due to insufficient sunlight. In addition, since the color to be developed is limited to a brown color and is a natural product, it can be fermented or spoiled by the enzyme remaining in the interior, resulting in a stain, and thus the desired diverse and beautiful natural color cannot be obtained. There is a problem.

  The present invention has been made in order to solve the above-mentioned problems, and the natural, beautiful, and various colors are obtained by using natural plant materials such as eye, gardenia, and cochineal as a dyeing agent on an amber-dyed cloth that has been dyed with amber. It is an object of the present invention to provide a natural staining method capable of expressing

  According to the first aspect of the present invention, a dyeing method using the koji dyed cloth according to the present invention for achieving the above object includes a step of rinsing natural fibers with warm water to soften, and a koji astringent extracted from the blue koji. A step of performing the first tanned color development while immersing the natural fiber to be dyed in the dyeing solution and exposing and drying to sunlight, and an oxidative coloring to be exposed to the air after immersing the natural fiber in the eye dyeing solution. Repeated twice, soaked in water diluted with vinegar, rinsed after being dipped in persimmon astringent dyeing, dried to give the second persimmon astringent coloring, then dipped in gardenia or cochineal dyeing liquid After kneading the fibers, immerse them in alum solution until clean water comes out, then expose them to sunlight and dry them, and then immerse them in persimmon astringent liquor and expose them to sunlight to perform the third astringent color development Ste Characterized in that it comprises a flop, a.

  According to the invention described in claim 2, in the dyeing method using the koji-dyed cloth according to the present invention, the first, second, and third koji coloring colors are dried by sunlight in the step of coloring. The duration is 3 to 4 days.

According to the invention described in claim 3, in the dyeing method using the koji dyeing cloth according to the present invention, the time to immerse in the eye dyeing solution in the step of performing the oxidative coloring is not less than 30 minutes, and the second koji coloring The time for subsequent immersion in gardenia or cochineal dyeing is characterized by being 10 minutes or longer.

  According to the dyeing method using the koji dyeing cloth according to the present invention, natural, beautiful and diverse colors can be developed by adding a natural dyeing material to the koji dyeing cloth having a brown color.

It is a flowchart which shows the dyeing | staining process using the koji dyeing cloth which concerns on one Embodiment of this invention.

Hereinafter, embodiments shown in the drawings will be described in more detail with reference to the accompanying drawings.
FIG. 1 is a flowchart showing a dyeing process using a wrinkle dyeing cloth according to an embodiment of the present invention.
As shown in FIG. 1, the dyeing method using the koji dyed cloth according to one embodiment of the present invention includes a natural fiber softening step (S10), a first koji astringent coloring step (S20), and an oxidation coloring step (S30). A natural dyeing step (S40) after the second amber astringency coloring step and a third amber astringency coloring step (S50) can be performed in this order.

The natural fiber softening step (S10) is a step of softening the natural fiber by rinsing the natural fiber, which is the dyeing raw silkworm, with warm water before dyeing the persimmon on the dyeing raw silkworm.
If the natural fiber is softened in the softening step, more dyeing liquid can be absorbed in the subsequent persimmon astringent dyeing and natural dyeing steps.

Next, a first strawberry astringent coloring step is performed in which the softened natural fiber is thoroughly dipped in the strawberry astringent dyeing solution and the sunlight is colored for 3 to 4 days (S20).
The extraction method of persimmon astringent is divided into a method of extracting from persimmon juice and a method of extracting from persimmon leaf juice.

First of all, the method of extracting persimmon juice from persimmon juice varies slightly depending on the region, but it uses persimmon from the beginning of July to the end of July, but from the persimmon until the end of the tannin component. To extract.
The koji has a gluing effect on the unripe blue koji, which is not only difficult to get foreign objects, but also good in summer.
If the koji is too ripe, the astringency is lost and it is not good for dyeing. Therefore, it is preferable to use the collected koji after taking out the juice on the day of collection.
The strawberry astringent dyeing liquid is extracted by pulverizing the collected buds with a mortar, a mixer or a large food mixer, putting them in a linen or cotton bag and taking out the juice.

  On the other hand, when extracting persimmon astringency from persimmon leaf juice, the persimmon leaves are shredded and crushed and placed in a linen or cotton bag to extract the persimmon astringent dyeing solution.

  In an embodiment of the present invention, the persimmon astringent dyeing solution dyes about 1.8 liters of the persimmon astringent dyeing solution on 5 yards of a natural fiber made of natural fiber, and is dried in sunlight for 3 to 4 days while producing the first persimmon astringency coloring. If done, the natural fibers will become an amber-dyed fabric.

  Next, the first tanned amber colored cloth is immersed in the eye dyeing solution for about 30 minutes, exposed to air, and oxidative coloring is repeated twice, and then immersed in water diluted with vinegar for about 10 minutes. Rinse (S30).

At this time, the eye dyeing solution is prepared by kneading 250 g of eye powder obtained by drying the eye into water on 5 yards of the koji dyeing cloth which is the dyeing base.
The eye dye liquid is used to color the raw koji into a blue color, and the amount of water mixed into the eye powder 250 g can be selected from 1.8 liters to 18 liters depending on the color density. .

  Then, the oxidatively colored candy-dyed fabric was dipped in strawberry astringent dyeing solution in the same manner as S20, and then dried with sunlight for 3 to 4 days to give a second strawberry astringent coloring solution, and then with gardenia or cochineal dyeing solution for about 10 minutes. Knead and soak in an alum solution for about 5 minutes, then remove it, rinse it until clear water comes out, and then dry it thoroughly with sunlight to perform natural dyeing (S40).

  Gardenia, which is a dyeing material used in the natural dyeing step, develops the raw koji into a yellowish color. The gardenia dyeing solution is obtained by boiling 100 g of dried gardenia fruit in water and decocting it. The amount of water to be mixed can be variously selected from 1.8 liters to 18 liters depending on the color density.

  The cochineal is a kind of insect that parasitizes cacti, and a cochineal dyeing solution is prepared by mixing 100 g of dried cochineal with water, boiling and decocting it. The amount can be selected from 1.8 liters to 18 liters.

  In order to develop a better color with the natural dyeing material in the natural dyeing step, the koji dyed cloth soaked with the natural material dyeing solution is dipped in the alum solution for about 5 minutes. The alum solution contains 50 g of alum and 5 liters of water. Prepare by mixing.

  Next, after dipping in the amber dyeing solution again in the same manner as S20 on the amber dyed cloth that has undergone the natural dyeing step, it is dried in sunlight for 3 to 4 days to produce a third amber astringent color, thereby producing various and natural colors. Color is developed on the candy-dyed cloth (S50).

  Although the present invention has been described in detail only for the specific embodiments described above, it will be apparent to those skilled in the art that various modifications and changes can be made within the scope of the technical idea of the present invention. It goes without saying that such variations and modifications belong to the scope of the claims.
