Unlike dyeing, it can express a variety of colors, has excellent fastness to washing of dyed fabrics, and has antibacterial properties and won

A method for preparing a new color ocher salt solution that exhibits an excellent effect that does not decrease the infrared emission ability and color ocher salt using the same

It's all about the color method.

Hwangto is a type of soil distributed throughout Korea, and is largely divided into loess and red earth. In general, iron oxide and carbonic acid

It has a high viscosity because it contains a large amount of calcium. In the literature, the loess for dyeing is sunlight in the east-facing zone.

It exemplifies that loess that received a lot of money is good.

The red earth is called a large magnet, and the ruler represents the meaning of red soil. The red color mentioned above is a large amount of acid

It is due to the fact that it contains iron. Such red soil is often used for drawing and landscape painting as a pigment, and it is used to express the skin color of portrait painting.

Used to be used.

The choice of soil quality depends on the defensive process that takes place after collecting the loess, not the loess obtained in any region in Korea.

La is different. In other words, it must go through a number of defense processes, and by repeating this defense process, the loess particles are uniformly and finely distributed.

Is that. However, it is obvious that the selection of high-quality loess is the most important than the defense process.

The above-mentioned ocher has been dyed and used for cotton fabrics, but these ocher dyed cotton fabrics were generally used in the times when dyes were precious.

If commoners wear white cloth made of cotton, etc. as clothing, the dirt will be easily burned.

It was only basic dyeing that was used by dyeing as loess, and the dyeing state, such as staining even in the dyed state.

There were problems such as discoloration due to washing, etc. even after dyeing, and the scientific civilization

With the development of the dyeing industry by chemical dyes, dyeing by ocher has existed.

Thus, various methods have been attempted for the resurrection of dyeing using ocher.

As part of this technology, Korean Patent Application No. 97-29418 is based on the method of defending the loess or separating by wind.

The obtained loess powder having a particle diameter of 0005 m or less is suspended in water to prepare a loess salt bath in which the loess powder is suspended, and the loess salt bath is heated.

W While maintaining the temperature of the dyeing bath above 90℃, immerse the fibers to be dyed and stir for 5 to 10 minutes to remove the loess powder.

After dyeing the phase, remove the dyed fiber from the dyeing bath and dry it, and when no more loess powder is leaked out as washing water

Until then, the method of dyeing fibers using the ocher powder of washing was introduced.

However, the above method is used several times during manufacturing to prevent the leakage of loess powder from the dyed fibers during the washing process.

Including the process of washing until the above ocher powder does not leak out, the color of the ocher powder pre-stained in this process is somewhat low.

Have a lower problem

In addition, Korean Patent Registration No. 10-301998 is a method of dyeing fibers with a solution of loess and water, wherein the material of the dye is

After collecting and sorting the yellow soil, the selected fine particles are mixed with clean water in an appropriate ratio and settled in a swollen form for about 4-6 days.

A step of obtaining a loess solution through the aging process while stirring with a stirrer, and the sulfur in the cotton woven layer by adding cotton to the aged loess solution.

After dyeing so that the soil solution is cut, repeat the process of drying in natural light by rinsing in clear water at least 5 times to complete dyeing.

Gyewa, the process of finishing through finishing after folding to an appropriate size while moistening all the dyed cotton

It provides a cotton dyeing method using ocher, characterized in that consisting of.

However, the above method has a problem in that it takes an excessive amount of time to dye the loess.

In addition, according to Korean Patent Publication No. 2003-51545, the present invention uses the ocher dye obtained by the method for preparing a new ocher salt solution.

Ocher dye, dyestuffs, other additives, and jade, germanium, totumarine powder, and pigments for color expression are added together.

Therefore, it provides a method of manufacturing loess dyes that are dyed using a conventional dyeing machine and a dyeing method using loess dyes.

C. However, according to the above method, the color obtained after dyeing is not accurately described, and it shows a very comprehensive pigment.

It can cause harmful problems to the body.

Accordingly, the inventors of the present invention have made research efforts to solve the above problems, as a result of which iron oxide or iron oxide as a natural inorganic pigment in ocher

After adding chromium oxide and a certain amount of sea salt as a mordant, dyeing is performed by immersing natural fibers in a dye solution within a certain temperature range for a certain period of time.

When performed, it was found that various colors of loess were expressed depending on the use of iron oxide or chromium oxide, thereby completing the present invention.

In addition, the present invention can be dyed by the simultaneous dyeing method, thus simplifying the dyeing procedure, and

It has excellent reliability, and does not reduce the antibacterial properties and far-infrared emission ability of loess.

Accordingly, an object of the present invention is to provide a method for preparing a new color ocher salt solution.

Another object of the present invention is to provide a color ocher dyeing method using the new color ocher salt solution.

As described above, since dyeing can be performed by the simultaneous dyeing method in the present invention, even a simple dyeing procedure is different from the existing loess dyeing.

It can express various colors, has excellent fastness to washing of dyed fabrics, and has antibacterial properties and far-infrared ray emission ability of loess

It can exhibit an excellent effect that does not decrease.

The present invention is to prepare a loess liquid in which water is mixed with water, and iron oxide or chromium oxide is mixed with the loess liquid, and then heated.

It can be rough.

The above-described loess liquid is mixed in a ratio of 100 g of water to 200 g of loess, and the iron oxide or chromium oxide is contained in 100 parts by weight of the loess liquid.

It includes a color ocher dyeing method of drying after performing (until no remaining).

Hereinafter, the present invention will be described in more detail.

In the present invention, after mixing iron oxide or chromium oxide as a natural inorganic dye in a certain amount of loess and adding sea salt as a mordant,

Dyeing can be performed by a simultaneous dyeing method by immersing natural fibers in the dye solution prepared by heating to the degree range, so the dyeing procedure is simple.

Yet, unlike conventional ocher dyeing, it can express various colors, has excellent fastness to washing of dyed fabrics, and

A new color loess salt solution that shows excellent antibacterial properties and does not reduce far-infrared emission ability, and a knife using the same

The present invention relates to a method for dyeing ocher. In the present invention, iron oxide and chromium oxide are used as components of the pigment as natural inorganic pigments together with the above-described ocher. In other words, in the present invention

Among natural inorganic pigments, iron oxide and chromium oxide were mixed with ocher to obtain various colored ochers.

Due to its use, it has succeeded in expressing various colors of ocher such as yellow, orange, red, black, brown, and green.

Among the inorganic pigments used in the present invention, iron oxide is the most important in the pigment market because of its universal color, low cost, stability, and non-toxicity.

I am in charge of a role. These iron oxides are not classified as dangerous goods in the RCRA regulations.

The above-described iron oxide includes red iron oxide, black iron oxide, brown iron oxide, yellow iron oxide, and the like.

Colors such as red, black, and brown can be obtained.

In addition, the iron oxide is very inexpensive compared to other pigments, and it is highly effective because it is used the most.

It also has an advantage that can be easily obtained from kites.

In addition, it can provide beneficial effects to the human body with various colors. It is mixed with ocher and dyed with natural fibers to create a multicolored ocher cloth.

Soft fibers and products are more common and can be mass produced.

The chromium oxide includes chromium oxide, chromium trioxide, chromium trioxide, etc., and can be used as a glossy green or black powder or crystal.

It is harder than quartz and hardly changes due to heat or air or water. Among them, it is the most used pigment.

It is also called chrome green, and it is used for coloring glass and pottery because it can obtain a green color, and it is widely present on the earth.

It is distributed.

The above mentioned loess, iron oxide, and chromium oxide are pigments, not dyes, so if the fibers are dyed and washed several times, the fastness is

It deteriorates and discoloration occurs.

Therefore, in the case of the present invention, the use of a mordant is essential. As such mordant, glutinous rice paste, glue, vinegar, alum and sea salt are used.

It can be used, but in the present invention, it is characterized in that the sea salt is selectively used.

In other words, since sea salt is easy to obtain, it is not only very economical, but also has the characteristics of simultaneous dyeing.

Select and use sea salt.

After finishing the dyeing process, in the washing step, post mordant treatment is followed for a vivid color of solid dyeing. The inventors of the present invention are raw soybean flour (raw

Soybean juice) was used. Here too, glutinous rice paste or glue can be used, but if raw soybean powder is used, the color fastness or color

The sharpness and the state of the dried fiber after washing with water are the best.

The raw soybean powder is pulverized by selecting a raw soybean selected from uncontaminated yellow raw soybean powder.

There is no yo.

On the other hand, when glutinous rice paste or glue is used, the vividness of the color of the natural colored loess is slightly lowered, and the washing process takes several times.

It is possible to point out the problem that the dyeing process is complicated. In the case of the present invention, since the above problems can be solved,

Dyeing is possible.

The present invention prepares a loess solution mixed with 100 g of water in a ratio of 200 g of loess in which loess was defended 7 to 10 times, and 100 parts by weight of the loess solution

Iron oxide or chromium oxide representing various colors is mixed in a ratio of 3 to 6 parts by weight based on 100 parts by weight of the loess solution.

By mixing the sea salt in a ratio of 7 to 8 parts by weight and heating it at a temperature range of 70 to 90°C, it is performed with a colored loess salt solution.

At this time, if the content of the iron oxide or chromium oxide is less than the above range, there is a problem that color expression is difficult, and the amount of use is

If it exceeds the above range, the color density is no longer expressed, and the present inventor cannot obtain the desired color.

That is, when iron oxide is used, colors are expressed in yellow, orange, red, chocolate, and black depending on the choice of iron oxide.

When using iron oxide, the amount used is more preferably 3 to 6 parts by weight based on 100 parts by weight of the loess liquid. Using chromium oxide

If you do, the color will appear as green or black. When using such chromium oxide, the amount used is 100 parts by weight of loess liquid.

In this case, it is better if it is in the range of 3 to 6 parts by weight. At this time, the sea salt is added as a mordant, and the sea salt is 7 based on 100 parts by weight of the loess solution mixed in a ratio of 200 g of loess and 100 g of water.

Sea salt is added in a ratio of ~ 8 parts by weight. If the amount of sea salt is less than the above range, the effect of mordant cannot be expected.

Exceeding the above range may lead to waste of sea salt and damage to natural fibers.

The natural colored ocher salt solution of the present invention as described above can be used for synthetic fibers, blended fibers and natural fibers, but for natural fibers

It is more preferable when applied.

The natural fibers include animal and vegetable fibers, and specifically include cotton, wool, hemp, silk, and the like. Dyeing the above natural fibers

When carried out, it exhibits excellent color expression and relatively strong heat resistance. In addition, the chemical fiber has absorption, moisture-proof, durability and heat retention.

Compared to oil, it is not only desirable because it is excellent, but it is also more human-friendly and eco-friendly.

In addition, the color ocher dye of the present invention is obtained by immersing the natural fiber for 30 minutes to 1 hour after heating the color ocher salt solution to 70 to 90°C.

After, dyeing for 20 to 30 minutes while maintaining the temperature at 40 ~ 60 ℃. This process is repeated 4 to 10 times, looking at the color intensity.

After that, the process of dehydration after immersion in fresh soybean meal aqueous solution of 10 to 15% by weight per 1 liter of uncontaminated water (groundwater) is repeated 5 to 10 times.

It is carried out by a method of drying after performing until there are no stains on the fibers.

In the case of dyeing fibers using existing loess, it is usually dyed with a known vegetable or animal dye and then loess.

It was carried out through an asynchronous dyeing process immersed in a liquid, and in this case, the dyeing took too much labor and overlook. Also asynchronous

By performing dyeing, the color expression after dyeing was cloudy, so that vivid colors could not be obtained.

I had.

In the case of performing the dyeing of the present invention, the above-described ocher, mordant, and a salt solution containing iron oxide or chromium oxide are prepared by boiling at high temperature.

However, in general, it is known that dyeing is performed better at a higher temperature, but in the case of the present invention, heating the dye solution to 70 ~ 90 ℃

It is more desirable to prepare.

Therefore, when dyeing is performed by adjusting the temperature of the dye solution to the above range, excellent color expression and

Fastness properties can be obtained.

When dyeing the fibers, not only the temperature of the dye solution described above, but also the time to immerse the fiber (fabric) in the dye solution and the degree of repetition of dyeing

This is a cost factor. When the above fibers were immersed in the dye solution and took about 30 to 40 minutes, the color expression was particularly excellent.

A desirable effect can also be obtained when the fiber is immersed and then cast for a certain period of time.

In addition, if the process of dyeing the dye solution is repeated several times, vivid colors can be obtained, but it is recommended that the number of dyeing is performed 4 to 10 times.

All. When the number of staining exceeds 10 times, the correlation with color expression seems to disappear.

It is already known that loess is a material having nuclear power line emission and antibacterial properties, but such antibacterial and far-infrared radiation

It varies depending on the materials used together.

In the case of the present invention, by using iron oxide or chromium oxide, the appearance of natural ocher color as well as iron oxide and chromium oxide

The color of the loess could be more varied, and the antimicrobial and far-infrared emission ability of the loess was not reduced.

At the same time, it was possible to improve the fastness of the dyed fibers.

Hereinafter, the present invention will be described in detail based on examples, but the present invention is not limited by the following examples.
