Description

Dyestuff extracted from natural indigo and Method Thereof and Dyeing method}

The present invention relates to a natural dye produced by using a natural plant, a method for producing the same, and a dyeing method using the same.

In general, natural dyes are those which can be used as dyes as they are or by some processing, and those which exist naturally. It is usually found in the areas of minerals, animals, and plants, among which the most abundance is in plants, the next is minerals, and some in animals.

Plant dyes can be used as they are because they are dyestuffs in the plant, and they can be put to practical use if they are processed considerably. All parts such as flowers, leaves, stems, roots, and fruits are used as plants. The plants used as dyestuffs in the world are estimated to be about 3,000 species in the literature, and the number will increase if the folklore survey progresses .

Conventional natural dyes have been used in species other than gardenia, gibberellinae, duckwood, mulberry, persimmon, cedarwood, clove, chestnut, acorn, jojoba, safflower, wormwood, madder, have.

It is known that spines are toxic and insecticidal and have the ability to prevent access by animals and insects such as venomous snakes that do not like the smell of spines.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

Production of the (natural) dye using the side of the present invention as shown in Figure 1 largely prepared salt powder side powder production step (S100) and lime powder side powder production step using lime and lime powder Mixing the salt powder prepared in step (S100) and water, using a soda ash or caustic soda using a dyeing step for adjusting the pH concentration to a pH concentration of 11 to 12 (S200), the salt solution Page powder manufacturing step (S100) and dye manufacturing step (S200) is made as follows.

1. Salt powder manufacturing step (S100)

1) Cleaning step (S110)

Wash the collected side with clear water.

Usually, only the leaves are harvested at dawn (sunrise).

2) Extraction of the saline solution (S120)

The washed side is mixed with water at a ratio of 2 to 1 by weight and left to mature for a predetermined time so as to be discharged into the salt solution contained in the side.

That is, mixing at a rate of 1 kg of water per 2 kg of washed side,

If the temperature is 20 ~ 25 ℃ aging 48 ~ 72 hours, if the temperature is 10 ~ 20 ℃ 78 ~ 120 hours aging, if the temperature is less than 10 ℃ aging for about 168 hours.

3) acquire the note (S130)

When left for a predetermined time to mature, the salt solution contained in the side is extracted from the side, to separate the side and the side to obtain the side.

4) mixing step (S140)

Lime is added to the mesa obtained in the mesa acquiring step (S130).

The amount of lime added is 5 to 1 lime per weight of lime.

That is, 2 kg of lime is added per 10 kg of the broth, and the white foam is formed. After stirring evenly to form a blue foam, the lime is stored for 1 to 3 hours.

The lime usually uses ash or oyster shell.

5) Page powder acquisition step (S150)

After lime has settled, the red water at the top is discarded, and the manure is removed to obtain water powder for salt solution.

The obtained saline powder for storage is easy to store, even when stored for a long time can be stored without changing the salt component of the side. In addition, it may be vacuum packaged or lyophilized so that it can be stored for a longer period of time in order to keep it unchanged.

2. Dye preparation step (S200)

1) Preparation of dye liquid (S210)

To prepare a dye solution by adding the salt powder side powder prepared in the salt powder side powder manufacturing step (S100) to water.

The temperature of the water is 10 ~ 12 ℃ is suitable, 1 to 2 weight of the salt powder for salt is added to 100 weight of water.

That is, 50-100 g of salt powder for salt solution is added to 5 kg of water.

2) pH concentration control step (S220)

The soda ash (sodium carbonate) or caustic soda (sodium hydroxide) is used to adjust the pH of the prepared dye solution to 11-12.

3) Heating step S230

The pH solution is adjusted to maintain the dye solution is heated for 10 to 20 minutes at 60 ℃ so that the saline solution is sufficiently discharged from the salt powder.

The pH of the dye solution is measured again. When the pH is below 11, soda ash (sodium carbonate) or caustic soda (sodium hydroxide) is added to adjust the pH to 11 to 12 to prepare a dye for dyeing.

Figure 2 shows the step of dyeing the fabric with a (natural) dye prepared using the side as shown in Figure 1, it is made as follows.

3. Dyeing step (S300)

1) Dye preparation step (S310)

A dye is prepared by adding a reducing agent to a (natural) dye having a pH of 11 to 12 prepared in the step (S200) for preparing a dye for dyeing.

Hydrous sulfite is used as the reducing agent, and 20-30 g of hydrousulfite is dissolved in 1 liter of cold water (4-8 ° C) in advance.

2) Temperature control step (S320)

The (natural) dye to which the reducing agent is added is heated to maintain at about 30 ± 2 ℃.

The amount of the reducing agent is preferably used at a minimum, and the criterion of the input amount is a reducing agent (water dissolved in hydrosulfite), and the color of the dye is changed from blue to yellow after 5 to 10 minutes by heating to about 30 ° C. This can be yellow or yellowish. That is, the reducing agent is added so that the color of the dye becomes yellow or near yellowish green.

3) Fabric immersion step (S330)

When the (natural) dye changes from blue to clear yellow or green, the prepared fabric is immersed for 5 to 10 minutes so that it is exposed to water and does not come into contact with air.

4) Oxidation step (S340)

The dipped and turned yellow fabric is oxidized to blue color.

The method of oxidizing the dipped and turned yellow cloth is a method of oxidizing by exposing it to air, or oxidizing by putting it in cold water, and either method is selected and oxidized.

5) Stabilization step (S350)

The pH is stabilized by neutralizing the pH of the fabric which has been oxidized and turned blue. That is, all the alkaline components are discharged from the fabric.

The stabilizing method may be performed by rinsing in cold water so that all the alkaline components are discharged from the fabric, or stabilized by using a neutralizing agent.

6) Drying step (S360)

The dyed fabric, which is discharged from the alkaline agent and stabilized, is dried naturally in a sunny place.

The dried dyed fabric may be rinsed in cold water to neutralize the remaining alkaline components.
