Description

Complex dyeing method using natural dyes {Manufacture method of a persimmon tannin dye and Dyeing method using fabric}

In general, natural dyeing refers to the process of coloring fabrics using vegetable, animal or mineral dyes.

All. The characteristics of these natural dyes are that the color is not saturated compared to chemical dyes, is eco-friendly, and is human-friendly.

There are many elements.

[0003] Natural dyeing has a natural color and excellent aesthetics compared to dyeing using synthetic dyes, and when using synthetic dyes

It has the advantage of being friendly to the environment without causing problems such as incidental wastewater and odor.

[0004] A variety of natural materials such as beer sludge, paulownia bark, grape skin, wild grape skin, etc. used as materials for natural dyeing

Is being used.

[0005] However, natural dyeing generally does not have high fastness to sunlight (sunlight), washing, sweat, dry cleaning, etc.

It has a problem that discoloration is likely to occur.

[0006] On the other hand, persimmons in which natural dyes are used are juices from unripe persimmons and are used as dyes or preservatives, and are generally

Since the Goryeo Dynasty, persimmon dyeing has been used in gal clothes, a folk costume of Jeju, and persimmons used as dyes contain a lot of tannins.

Native green persimmon collected around July-August, which contains and rich in pigments, is used, and the basic principle of dyeing is the tannin component of green persimmon.

It combines with the fiber and solidifies, making the fiber stiff, and when the fiber dyed with persimmon is exposed to sunlight, it overlaps with oxidation.

As it becomes, it turns to dark brown (褐色).

However, these traditional natural persimmon dyeing methods are pointed out as disadvantages of fading after dyeing and fading during washing with water.

Came.

In the present invention, native green persimmons and Ecklonia cava are pulverized, filtered, freeze-dried, and then powdered to prepare natural powder dyes.

After that, by sequentially dyeing the fabric, dyeing dyes are made only from natural resources and contain environmental hormones or harmful substances.

It provides a complex dyeing method for fabrics using natural dyes that prevent environmental diseases.

There is a purpose.

As described above, according to the present invention, dyeing dyes such as green sensation and Ecklonia that do not contain any chemical components

1st and 2nd dyeing steps are performed to cause environmental diseases such as atopy as the fabric does not contain environmental hormones or harmful substances.

By providing fabric that is not used, it is possible to produce human-friendly products, which can create new added value.

In the first dyeing step, persimmon natural dye, and in the second dyeing step, persimmon natural dye are used sequentially.

Dyeing is performed twice on the hem, so that it is dyed in natural and beautiful colors.

It has an effect that can appeal to you.

[0014] In addition, the refining agent used in the refining step not only easily removes impurities from the fabric before the first and second dyeing steps

The effect of improving the convenience of work by maintaining the physical properties of the fabric so that the first and second dyeing steps can be easily performed.

There is.

In addition, by using natural resources, persimmon and persimmon, persimmon natural dye powder and persimmon natural dye powder and persimmon from Jeju

Natural salts can contribute to the increase of income in farming and fishing villages by promoting the consumption of fetuses, while also being able to commercialize natural dyes themselves.

Color can be generalized and widely distributed to increase added value, and at the same time, persimmon and Ecklonia dye are powdered to

Because it is easy to store, it can be used anytime and anywhere, so it has the effect of easy commercialization.

In order to achieve the above object, the present invention is a natural salt for preparing a persimmon natural dye powder and a persimmon natural dye powder, respectively

Preparation stage; After removing impurities from the fabric to be dyed, boil for 25 to 35 minutes in hot water maintained at 45 to 55°C.

Refining step of washing and drying 2-3 times with water; After filtering the persimmon natural dye powder in a mesh made of 300 to 600 mesh, the filtered persimmon natural dye powder is dissolved in water at room temperature to make it into persimmon natural dye, and the fabric is added to the prepared persimmon natural dye.

A first dyeing step in which persimmon dyeing and drying are performed; Ecklonia natural dye powder is applied to a mesh body made of 300 to 600 mesh.

After rinsing, dissolve the filtered Ecklonia cava natural dye powder in water maintained at 60°C, and make it with Ecklonia Natural Dye.

Put the fabric that went through the first dyeing step to dye the Ecklonia cava, and then dry them in a shaded and well-ventilated place after Ecklonia dyeing.

A second dyeing step in which the business is performed; The fabric that has gone through the second dyeing step is washed with water until no natural Ecklonia dye comes out.

Fabric using natural dyes consisting of: a post-treatment step of drying in a shady and airy place after dehydration

It provides a complex dyeing method of.

And the refining step is a refining operation is performed by a refining agent to remove impurities from the fabric, the refining agent is water

5L, Oxidation desizing agent 10 ~ 15g, Alkaline penetrant 10 ~ 15g, Hydrogen peroxide solution 20 ~ 35g, Fruit water stabilizer 10 ~ 20g, Emulsifying and dispersing agent

It is characterized by consisting of a mixture of 10 to 20g.

[0011] The persimmon natural dye powder is pulverized by removing the stem and seeds of the Jeju native green persimmon collected around July to August, putting it in a grinder

Persimmon preparation step of preparing raw materials of persimmon; The weight ratio of the green persimmon pulverized product and water prepared in the persimmon preparation step is 4 to 6:

Mix in 1 to prepare a liquid mixture, and filter several times using a mesh sieve consisting of 300 to 600 mesh.

A mixing step of removing solids and foreign substances from the liquid mixture in which the persimmon pulverized product and water are mixed; High in the mixing step

A storage unit that stores the mixture from which the mold has been removed for 1 to 1 hour and 30 minutes in a low-temperature storage at 2 to 0℃

system; After filtering the mixture through the storage step using a mesh sieve consisting of 300 to 600 mesh,

A powder step of lyophilizing the mixture by lyophilizing it for 2 to 4 hours at a temperature; characterized in that it is produced by sequentially performing

Shall be

[0012] The Ecklonia cava natural dye powder is obtained by collecting Ecklonia from September to November at the coast of Jeju, and putting Ecklonia in flowing water and fire

After the pure water is removed and dried, the dried Ecklonia cava and water are mixed in a weight ratio of 1:30 and placed in a container for 90 to 120 minutes.

Heating step of heating to 110 ℃; The mixture that has gone through the heating step is filtered through a filter cloth or a sieve to extract the salt solution

The extracting step of the salt solution; After cooling the Ecklonia cava salt solution extracted in the Ecklonia cava salt solution extraction step at room temperature,

After filtering with a mesh sieve made of sheath, freeze-drying at a temperature of 0 to 2℃ for 2 to 4 hours to separate

Powder step of rolling; characterized in that it is produced by sequentially performing.
