Description

The present invention relates to a natural dye method using a mineral natural dye and a product thereof for dyeing an object to be dyed (clothing, fabric, window paper, other natural fibers), and more specifically, a colored mineral substance . A natural dye produced by blending finely pulverized stone powder with clear lacquer obtained by transparently processing sap extracted from lacquer trees and clear oil obtained by processing sap extracted from oil paulownia trees, The present invention relates to a lacquering method in which a dyed material is immersed in a diluted dye solution extracted from pine or persimmon and a dyeing method using natural dyes and a product thereof.

Natural dyes that have been used for thousands of years have limited raw material collection and complex dye extraction processes. Furthermore, since the dyeing process is complicated and requires a large amount of labor, the use of natural dyes is gradually decreasing as chemical dyes are developed after the 19th century.

However, in order to solve the problem of water pollution, which is a disadvantage of chemical dyes, while active research and restoration work on traditional costumes such as Hanbok, a Korean national costume, emphasizes the protection of the environment and nature. There is an increasing interest in plant dyes that are more environmentally friendly, and research is underway to overcome the reproducibility of natural dyes.

Traditional dyeing techniques for fabrics have been dyed using materials obtained from nature, ie, plant, animal and mineral raw materials, before chemical dyeing methods are used.

As an example, vegetable dyes are taken from petals, berries, trunks, roots, leaves, etc. of plants with shades, for example, red is from petals called safflower, yellow is gardenia seeds and grass yellow From the sap, the blue color was collected from the trunk and leaves belonging to the family Tedaceae, and the turmeric color was collected from the root and trunk of the turmeric belonging to the Ginger family and used as a dye.

In addition, safflower dyeing, suho dyeing, camellia dyeing, trash dyeing, kihada dyeing, gardenia dyeing, turmeric dyeing, uren dyeing, enju dyeing, carious dyeing, Yamakido dyeing, purple grass dyeing, indigo dyeing and ai dyeing. There are various dyeing methods such as red dyeing.

The dyeing method described above is a dyeing method classified according to hue by dyeing, and several conventional dyeing techniques will be described as an example.

Suho-dyeing is dyed using a liquid that has been decocted by taking the red contents of the tree, Suho or Sugi, Suyoshigi, Suyoshi, Tanki, Kokusai and Taki. When a deep pale red color is desired, it is mordanted with alum, and when cocoon is desired, it is mordanted with iron acetate.

Koji dyeing is also called the so-called dyeing method of dyeing the roots, but it is another dyeing method for dye plants used as a red dye. The yellowish red root of this Sone vine has long been used as a medicine and dye. It is a typical mordant dye that is difficult to dissolve, difficult to dissolve, and must use a mordant (alum). When dyeing cotton (white cloth), after mordanting with lye, treat with alum.

The mordanting method using lye is first immersed in cold lye. After soaking the roots in water at about 50-60 ° C. and then immersing them again for a while, they will be dyed neatly in a bright yellowish red. If you use iron mordanting instead of lye mordanting, it will turn brown.

The red dyeing is also called red dyeing or red dyeing, and is used when dyeing red using safflower, suho, koji (sone) or the like. In the red dyeing method by safflower, that is, safflower dyeing, petals are left as is or fermented, and hot water is added to the solution lacking the sieve to remove the yellow juice. Next, throw in the lye and throw away the first water, take hot water again and drain the water. When this solution turns red, waste juice is added to make a dye bath, and the cloth is soaked and dyed at 50-60 ° C. until the desired concentration is reached. If you want to dye it in a deeper red, dry the safflower and waste liquid precipitates and dye them as powder.

Garbage dyeing is a deciduous vine shrub belonging to the family Lotus, which is a dyeing method using trash which has five tastes of acidity, bitterness, pungent taste, salty taste, and sweetness. After diluting to an appropriate concentration with water and making a dyeing solution, a cloth is put into the dyeing solution and boiled for dyeing. Garbage is a dye used for dyeing red.

The yellow line is dyed yellow from plants such as turmeric, auren, enju, yellowfin, gardenia, karyas, and yamakaidou. Dip overnight in dyed solution and add lye. After performing indigo dyeing, yellow dyeing gives a green dyed product.

Gardenia dyeing is a dye that can be dyed without a mordant, and the fruit of gardenia belonging to the rhizome family is dried and drained, this solution is decocted, acid is added and dyed. Mainly used for dyeing hemp fabrics such as Kotobuki.

Turmeric dyeing is a direct dye called turmeric or deep yellow as a raw material for “curry”, a traditional Indian dish. The roots of turmeric, a perennial plant of the ginger family, are torn off and dyed with a solution drained.

In addition to the dyeing raw material and the dyeing method as described above, there are various raw materials and dyeing techniques therefor, but a description thereof will be omitted.

However, since the dyeing technique using the plant material as described above can be dyed only by a unique dyeing technique depending on the dye material, the dyeing method is different for each raw material, unlike the chemical dyeing method in which the dyeing method is the same. Therefore, it is very cumbersome and inconvenient, and since the plant material is used as a dye, the color is clean but the brightness is reduced and thin.If the dyed clothes are stored for a long time, the clothes will be damaged by pests such as paper fish. It is easy and has the disadvantage of fading or decoloring by frequent washing.

On the other hand, the dyeing method using mineral materials has the advantage that the degree of decolorization during washing is less than that of vegetable dyes and has a strong color, but the reproducibility is low and it is difficult to collect the raw materials of the dyes, and the price is low. There is a disadvantage of being expensive.

As described above, the present invention proposes results obtained by the present inventor through repeated trial and error for several years in order to solve the problems caused by conventional staining.

The object of the present invention is to dye the object to be dyed with a mineral natural dye to give antiseptic, insecticidal and bactericidal action to the dyed object, the hue of the dyeing is clear and dark, the hue is difficult to decolorize, and environmental pollution is completely avoided. It is to provide a dyeing method using mineral natural dyes that do not occur and products thereof, especially transparent lacquer that is made by processing sap extracted from lacquer tree into stone powder that is finely pulverized colored minerals , A lacquering method in which a mineral natural dye blended with a bright oil obtained by transparently processing sap extracted from oil paulownia trees is diluted with a dilute solvent extracted from pine or persimmon and a dyeing method using a natural dye and To provide that product.

Whether the method of dyeing using lacquer coating and natural dyes according to the present invention and products thereof are distilled by adding water to a resin extracted from pine in order to elute the dyes of natural dyes when dyeing the dyed goods with natural dyes Or the first step of producing a dilute solvent obtained by adding water to a resin extracted from straw and the sap obtained by squeezing the seeds of oil paulownia on stone powder obtained by pulverizing a mineral with a specific hue Mineral natural dyes are manufactured by purifying the clear oil produced by boiling gradually and the fresh lacquer extracted from the lacquer tree, and then irradiating with UV light for a certain period of time, mixing the transparent lacquer produced transparently. A second stage, a third stage in which the dyed product is soaked in a dye solution in which the natural dye is diluted in the dilute solvent of the first stage, and a dyed product to be dyed is taken out of the dye solution for a certain time. Can be achieved by the fourth stage of drying. .

The natural dye according to the present invention comprises the components of sap of lacquer tree (transparent lacquer) and oil paulownia tree (light oil) if the fabric is soaked in a dye solution mixed with a dilute solvent for a certain period of time. The dye pigment penetrates and absorbs into the fiber of the dyed object, and not only protects the dyed article by the antiseptic, insecticidal, antibacterial and antibacterial properties of the transparent lacquer, but also acts usefully on the human body. By protecting the surface of the fiber with the elastic coating film of the sap of the tree, the hue is clear and the surface of the fiber is glossy. Property is enhanced, and there is an effect of extending the life of the article to be dyed.

Hereinafter, the dyeing method using the lacquer coating and the natural dye according to the present invention and the product will be described in detail.

The natural dye according to the present invention includes a stone powder obtained by pulverizing a colored mineral , a mineral natural dye having a predetermined caking force by adding a caking agent to the stone powder, a pigment of the natural dye, and a caking agent. It consists of a dilute solvent that regulates the concentration and viscosity of the dyeing liquid.

The stone powder according to the present invention is a finely pulverized colored mineral that is naturally distributed to a 2500 mesh using a ball mill. It is desirable that the particle size is pulverized extremely finely so that the pigment contained in the stone powder is sufficiently and fully eluted by the dilute solvent.

The color dye is added to the stone powder and provides a waterproofing, insecticidal, antiseptic, insecticidal and mordant effect to the dyed product dyed with the viscosity and adhesive components contained in lacquer and bright oil (binder).

As examples of the use of the binder according to the present invention, sap of lacquer tree and sap of oil paulownia tree (Aluretes fordi Hemis) were employed.

When a lacquer tree is scratched, the sap flows from the lacquer tree to protect the scratch, which is called raw lacquer. Raw lacquer is an off-white milky liquid with approximately 70% urushiol, rubber (4-8%), nitrogenous material (2-3%), enzyme (laccase) and moisture (10-10). 20%).

The characteristics of raw lacquer are grayish in the initial stage, gradually become black due to deterioration and become opaque as time goes on, become viscous, have a characteristic odor, especially waterproof, insectproof, antiseptic, insecticidal and mordant effects As a result, it is mainly used as a paint and cut-off material for woodware and crafts.

In raw lacquer, many components with different chemical properties are separated in the tissue of the bark, and when the epidermis is damaged, it is mixed in an emulsion state containing a large amount of urushiol, moisture and polysaccharides, The condition is not uniform, it contains an excessive amount of enzyme, and rapid surface hardening occurs even in a low humidity environment.

The composition of such raw lacquer tends to cause wrinkles that cause defects in the lacquer coating film due to the rapid polymerization action when lacquering wooden products, and discoloration of the lacquer coating film due to a large amount of polysaccharides. Deterioration of the coating film due to ultraviolet rays occurs.

Lacquer coating using raw lacquer is a traditional paint that is durable enough to maintain the lacquer coating film even after thousands of years, and is still used in products that still require strong durability. ing.

Because lacquer coating has strong chemical resistance that does not corrode at all into various organic solvents, industrial coatings that require strong corrosion resistance, oil storage tanks, oil transmission pipes, LNG storage tanks, piping for chemical factories It is also developed as an industrial paint for various uses such as equipment.

As a method for producing raw lacquer in a transparent manner, after removing foreign matter and impurities from sap extracted from lacquer wood (hereinafter referred to as raw lacquer), if the raw lacquer is stirred for about 2 hours, The color changes to transparent (hereinafter referred to as “transparent lacquer”) due to degradation by the polysaccharide, but its properties are maintained. The ultraviolet irradiation device used was a medical ultraviolet lamp.

Raw paulownia oil is extracted from the fruit of oil paulownia tree (also called paulownia tree), and if you press the oil paulownia tree with a compressor, a thin milky white oil is extracted, but it dries quickly and is viscous It is high and forms a thick and elastic coating film after drying. The oil has a smoothing action and has long been used as a coating oil for floor paper and umbrella paper in Ondol rooms. Recently, it is also used as a raw material for architectural paints, varnishes, and printing inks.

As a method of producing raw tung oil transparently, if raw tung oil is put in a container and boiled (this is called mature tung oil), milky white raw tung oil gradually changes to transparency, which is called bright oil. As for the bright oil, even if it changes from raw tung oil to bright oil, the physical and chemical properties are maintained as they are.

As mentioned above, if colored raw lacquer and raw paulownia oil are mixed with stone powder, the color of stone powder and the color of raw lacquer and raw paulownia oil are mixed, making a color that is difficult to predict, so make the desired color For this purpose, clear lacquer and clear paulownia oil are used.

In the present invention, it is added so that the sum of transparent lacquer and bright oil becomes 18 to 22 parts by weight (the rest is stone powder), and when kneading the flour to make bread, the kneaded material sticks to the hand A natural dye having a low viscosity was produced.

In this way, natural dyes adjust the addition ratio of dilute solvent depending on the viscosity, but as the dilute ratio of natural dyes increases, the amount of elution of clear lacquer and bright oil increases, and the fluidity of the dye liquor decreases and dyeing Efficiency is reduced.

In the present invention, the dilution ratio of the natural dye to the dilute solvent was a dye liquor in which the natural dye was diluted at least 0.5 parts by weight and at most 45 parts by weight with respect to 100 parts by weight of the dilute solvent.

If the dilution ratio of the natural dye exceeds 45 parts by weight, the components of lacquer and bright oil will be excessively eluted in the dyeing solution, increasing the viscosity of the dyeing solution. The coating becomes thick and the drying time of the dyed product is delayed.

If the stone dye is diluted with 60 parts by weight or more in a dilute solvent, the viscosity of the dyeing solution may increase, and the dyeing solution may not sufficiently penetrate into the object to be dyed, resulting in uneven dyeing.

On the other hand, if the natural dye is diluted to 0.5 parts by weight or less in a dilute solvent, the amount of dye pigment eluted is reduced, and the tint of the dye becomes cloudy and thin.

A method for producing a dilute solvent for diluting the concentration of the dye liquor by eluting the natural dye pigment and transparent lacquer and bright oil components into the dye liquor will be described.

The dilute solvent activates the interface so that the components of the pigment and lacquer can easily penetrate into the fabric fibers while eluting the pigment and lacquer of the natural dye, and acts to enable dyeing to a uniform hue.

In the present invention, either pine nut oil or camphor oil is used as the dilute solvent, and the production method thereof is as follows.

As for the method for producing pine knot oil, a pine trunk is cut into a V shape with a blade, or a groove is formed in a spiral shape, and the same amount of water is poured into the resin flowing out from the rupture opening and distilled.

Pine knot oil is stronger than pine oil scent before distillation, but after distillation a small amount of pine scent remains, is clear and colorless, and has a viscosity similar to water.

Pine nut oil is harmless to the human body even if it is taken, and the drying rate is almost similar compared to water. Collect mainly in summer.

Camphor oil is produced by adding the same amount of water to the resin that flows out of the wound when it is damaged, and is distilled. It is a clear liquid and has a slower drying rate than pine nut oil. . Viscosity is almost similar to that of pine nut oil, and is collected in summer as well.

Pine nut oil has a higher drying rate than camphor oil, so it is desirable to use pine nut oil as a dilute solvent in winter when the atmospheric temperature is low, and it is desirable to use camphor oil as a dilute solvent in summer when the temperature is high.

The lacquer component and the bright oil component can be eluted by selecting any of the diluted solvents of pine knot oil and camphor oil produced as described above, and the dye can be dyed on the object to be dyed.

As described above, add a desired amount of dilute solvent, ie, pine nut oil or camphor oil, into the dyeing tube, add the natural dye in the desired ratio, stir the dilute solvent, and dissolve the natural dye. After dyeing, put the object to be dyed in the dyeing solution, stir the object to be dyed by hand, or stir it while turning it over with a stick, and the dye pigment and transparent lacquer and bright oil components will penetrate into the fiber and be dyed. The

After a certain period of time, if the object to be dyed is taken out and dried sufficiently, a dyed object dyed in the target color can be obtained.

The above-described staining method of the present invention is arranged as follows.
The first stage is a process for producing a dilute solvent. In dyeing the fabric with natural dyes, a resin extracted from the ruptured portion of the pine shell is ruptured in order to elute the dye pigment into the dye liquor. A pine nut oil dilute solvent distilled with water or a camphor oil dilute solvent distilled with water added to a koji resin.

The second stage is a process for producing natural dyes. The sap obtained by squeezing the oil paulownia tree into a finely pulverized mineral powder with a specific hue is gradually boiled and transparent. After purifying fresh oil produced in lacquer and fresh lacquer extracted from lacquer trees, natural dye is produced by mixing transparent lacquer produced transparently by irradiating ultraviolet rays.

The third stage is a process of dyeing the object to be dyed, in which the dilute solvent produced in the first stage is placed in a dyeing cylinder, and the natural dye produced in the second stage is dissolved in the dyeing cylinder. Place the object to be dyed in the liquid and dip it for a certain time (about 30 minutes).

The fourth stage is a process of taking out the fabric soaked in the dyeing liquid and drying it, and the drying method is not particularly limited.

As described above, a dyed product dyed with a natural dye neutralizes lacquer components through a known heat treatment to complete the dyeing.

In the dyed product produced as described above, a very fine coating film is formed on the surface of the fabric fibers as the components contained in the lacquer and bright oil deteriorate and harden.

As explained above, according to the lacquer coating and the dyeing method using natural dyes according to the present invention, the dyed product has antiseptic, insecticidal, antibacterial, bactericidal and antibacterial properties depending on the components of the lacquer. In addition, the dyed product can be prevented from being damaged by pests, and the glossy effect of clear lacquer and bright oil gives the dyed product a glossy, clear hue, and almost no discoloration and discoloration. Anyone can easily stain with a unified method.
