Description

Pattern formation method using persimmon {Pattern dyeing method for persimmon juice}

The present invention relates to a pattern forming method using persimmon, and more particularly to a pattern forming method using persimmon that can produce a clear and aesthetic natural pattern using persimmon leaves or persimmon juice.

Persimmon is a fruit tree unique to East Asia, native to Korea, China, and Japan. There is a record of persimmon tree cultivation in China's largest agricultural technology book, Jing Min Zi, and the tree is also included in the Xinshu vinegar of the Tang Dynasty. In Korea, there is a record of black sage (mature persimmon) in Goryeo Myeongjong (1138) and persimmon in <Agricultural Aggregation>.

It is a large leafy tree with a size of 6-14m. Yellow-white flowers bloom in Onyuwol and oranges ripen in October. Persimmons have strong water washing and few pests, so they are relatively cultivated and are mainly used for reproduction. For processing, young persimmons are grown, the main component being tannin (or tannin). Dyeing with tannins is said to be good for breathability, high color fastness, and strong moisture, so that the nets and work clothes are coated on the coast and islands.

Here, dyeing fastness refers to the resistance of the color to external conditions, and there is a significant difference due to the nature of the dye, the dyeing state, dyeing amount, the nature of the fiber, the surface state of the dye, the processing agent on the fiber, etc. Dyed fibers require sufficient resistance and durability to the conditions and conditions of use during the manufacturing process or in use.They have many effects such as daylight, washing, weatherproof, sweat, friction, water, chlorine bleaching, seawater and dry cleaning. If you receive it will fade or discolor. In this case, the color resistance to external conditions is called dyeing fastness, and the dyeing fastness becomes the most important item in evaluating the performance of the dyeing material.

In conventional dyeing methods using persimmons, persimmons are obtained by immersing the persimmons, preferably from green persimmons, until they ripen red on the fibers and exposing them to sunlight for several weeks to several months, thereby obtaining dyeings.

The dyeing using such a conventional persimmon utilizes a phenomenon in which the tannin component in the persimmon component is dyed onto the fiber and is colored reddish brown as the tannin molecules are slowly polymerized by the energy of sunlight. In other words, as the number of days of sunlight increases, the tannin molecules increase in molecular weight and color is deepened accordingly. Therefore, it takes much labor and much labor to obtain fibers of a desired color.

Then, in order to make a patterning dye using persimmons, the fabric after the dyeing is carried out by directly painting the desired pattern by burying the persimmons with a brush or other tool. Therefore, there is a problem that a lot of labor and seal is required to obtain the desired pattern. In addition, by manually drawing the pattern of the desired pattern manually, the appearing pattern is uniform and standardized, so that it has an artificial feeling.

On the other hand, the traditional method of forming a pattern on the fabric is a technique called taichi dyeing. Before dyeing, the part of the dye (thread or fabric) is tightly tied or wound with thread to prevent penetration of the salt solution, and then dyed by the dyeing method. It is a dyeing method in which a pattern appears. By repeating this method, you can get tones of different shapes, such as colors that fade over each other.

In addition to threading, there are also ways to achieve the same effect by using plates or by using pipes, rods, and boxes. The general method is to draw sketches on the fabric and then do various ways of drawing according to the sketches. Tighten yarn is usually used for sturdy yarns such as yarn and cotton yarn, and the dyeing method is the same as the normal dyeing method. You may not penetrate. In addition, various dyeing results can be obtained by changing the color of the saline solution. Allow the finish to dry sufficiently so that the thread is unrolled and the bundle is completely pulled out.

As such, the stifling salt is troublesome to use a special tool to block the penetration of the dye to a specific site and obtain a certain pattern.

Accordingly, an object of the present invention is to provide a pattern forming method using a persimmon that can overcome the above-mentioned conventional problems.

Another object of the present invention is to provide a pattern forming method using persimmon that can easily obtain a vivid and aesthetically excellent natural patterning.

Still another object of the present invention is to provide a pattern forming method using persimmon, which is well colored and softens cloth to perform dyeing.

Still another object of the present invention is to provide a method of forming a pattern using persimmon that can naturally form a pattern salt without using a special apparatus or equipment.

Another object of the present invention to provide a pattern forming method using a persimmon excellent in color fastness.

According to an embodiment of the present invention for achieving some of the above technical problems, the pattern forming method using persimmon according to the present invention, the extraction step of extracting persimmon salt solution by squeezing the juice of persimmon or persimmon leaf; Immersion and dehydration step of immersing the cloth to form a pattern in the persimmon salt solution to sufficiently immerse for a predetermined time and then dehydrate the cloth appropriately; To form irregular patterns, the technique of folding all or part of the dehydrated fabric, the twisting technique of all or part, the technique of bending all or part, the technique of uniting all or part of the fabric, and rolling all or part of it ( a pattern forming step of fixing the fabric in the state of applying at least one selected from a plurality of techniques including a rolling technique; And a drying step of drying the fabric to which at least one technique selected from the plurality of techniques is applied, to produce a pattern salt using a discoloration difference depending on the degree of exposure to air.

Before the immersion and dehydration step may further comprise the step of first dyeing the cloth as a whole using a natural salt solution extracted from the material containing the persimmon saline solution or chrysanthemum flower, side, safflower.

After the drying step, it may further comprise the step of ironing the dried cloth to develop a good color.

In the drying step, the cloth may be dried in an environment that does not contain sunlight, including shade or shade through the air.

A certain amount of salt may be added to the persimmon salt solution so that the color development is good and the cloth is soft.

The persimmon salt solution may be configured by mixing a suitable ratio of water according to the type or use of the cloth.

According to the present invention, it is possible to easily obtain a vivid and aesthetically excellent natural patterning. In addition, the dyeing can be performed so that the fastness is strong. In addition, the color development is good, and the fabric can be dyed by softening the cloth, and a natural and deep taste can be dyed compared to the drying method using sunlight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings without any intention of providing a thorough understanding of the present invention to those skilled in the art.

1 is a flow chart showing a persimmon dyeing method according to an embodiment of the present invention.

As shown in Figure 1, the pattern forming method using persimmon according to an embodiment of the present invention, extraction step (S10), dipping and dehydration step (S20), pattern forming step (S25), and drying step (S30) May be performed in the order of

The extraction step (S10) refers to the step of extracting the persimmon salt solution. The persimmon salt solution may be divided into a method of extracting through the juice and a method of extracting through persimmon leaf juice.

First, the method of extracting the persimmon salt solution through the juice, although the difference in time depending on the region, but using the persimmon from early July to early October, preferably persimmon is extracted through the blue persimmon until ripening red. Persimmon is less ripe blue persimmon because the color appears better. First of all, the persimmons collected are good to use the juice on the day of collection, when the persimmons are soft, it will not be good for dyeing because the thin groups disappear.

The collected persimmons are ground with a mortar, blender, or large food blender and put in a burlap or cotton bag to squeeze juice to extract the persimmon salt solution.

Next, chop persimmon leaves, go to a blender, and squeeze juice into a burlap bag or cotton bag to extract the persimmon salt solution.

When a certain amount of salt (for example, about 10 to 15 g) is added to the persimmon salt solution based on 2 liters of the persimmon salt solution, color development is good and the fabric to be dyed is softened. In addition, a certain amount of water may be added to the persimmon salt solution depending on the type and use of the cloth.

Next, in the immersion and dehydration step (S20), immerse the well refined cloth in the extracted persimmon salt solution and rub well for a predetermined time (10 to 30 minutes (typically about 20 minutes)), so that the fabric is completely transferred to the persimmon salt solution. After soaking, the cloth soaked with the persimmon saline solution is properly dehydrated.

Further, before the immersion and dehydration step (S20), the cloth may be further dyed and dried using the persimmon saline solution or another natural saline solution as a whole. This can be done if you want to make the color darker.

In this case, the salt solution may be a persimmon salt solution, a salt solution extracted from chestnut bark, yellow earth salt solution, chrysanthemum flower salt solution, side salt solution, safflower salt solution and various other natural salt solutions.

Next, in the pattern forming step (S25), the immersion and dehydration step (S20) performs a work to make a pattern on the fabric soaked well and dehydrated properly.

First, a plurality of techniques including a technique for folding all or part of the fabric, a technique for twisting all or a portion, a technique for crushing all or a portion, a technique for lumping all or a portion, and a technique for rolling all or part Fixing the fabric through the immersion and dehydration step (S20) with at least one pattern technique selected from among the pattern techniques.

In the drying step (S30), the at least one pattern technique is applied to dry the fixed cloth in an environment in which sunlight does not enter, such as airy shade or shade.

In general, persimmon dyeing is known to direct sunlight to dry on a sunny day. However, after research and experimentation, there is no other way to make pattern prints, but drying in a sunless environment such as airy shades or shades is more vivid than drying in sunlight. I found out that it is aesthetically superior and the naturalness is a dye of a color with a deeper taste of color.

In addition, when various fabrication techniques are applied when drying the fabric which has undergone the immersion and dehydration step (S20), the fabrication process may be performed according to a portion of the fabric exposed to air, a portion less exposed, and an unexposed portion (folded portion). Noticed a discoloration difference. In other words, the color changes depending on the degree of exposure of the fabric to air during drying.

Based on the results as described above, when drying the fabric through the immersion and dehydration step (S20), by applying the above-described patterning techniques it is possible to generate a patterned salt having an irregular and constant shape.

After the drying step (S30), the dyed cloth is ironed. In some cases, the dried cloth may be washed with water, that is, washed with water and dehydrated before ironing. When the ironing is performed, the color becomes darker and the pattern becomes clear, so that the fastness is excellent.

2 to 7 are photographs showing examples of the pattern techniques and the pattern generated by applying the pattern techniques.

Figure 2 shows an example of the pattern of the folded pattern to the pattern dye using persimmon, Figure 3 is a photograph of an example of further performing side dyeing on the cloth having a pattern formed by the pattern method of Figure 2 .

FIG. 4 shows an example of a pattern technique of twisting and crimping a cloth, and FIG. 5 shows a pattern that appears when the fabric generated by the pattern technique of FIG. 4 is unfolded. In this case, after performing the initial dyeing using the salt solution extracted from the chestnut, it is an example of generating a pattern salt using the persimmon salt solution.

FIG. 6 shows an example of a pattern technique made by twisting the whole fabric after dyeing, and FIG. 7 shows a pattern that appears when the fabric generated by the pattern technique of FIG. 6 is unfolded. In this case, after performing the initial dyeing using the persimmon salt solution, it is an example of generating a pattern salt using the persimmon salt solution.

As shown in FIGS. 2 to 7, a technique for folding all or a portion of the fabric, a technique for twisting all or a portion, a technique for bending all or a portion, a technique for lumping all or a portion, and all or a portion It can be seen that the patterning can be produced by a plurality of patterning techniques including a rolling technique. In all cases of FIGS. 2 to 7, a drying step of drying in an environment without sunlight, such as airy shade or shade, should be performed in common.

The present invention includes a technique for folding all or a part of the fabric, a technique for twisting all or a portion, a technique for bending all or a portion, a technique for lumping all or a portion, and a technique for rolling all or a portion Although a plurality of pattern techniques have been described, it can be obvious to those skilled in the art that various pattern techniques can be used to generate pattern salts.

As described above, according to the present invention, natural patterning which is vivid and aesthetically excellent can be easily obtained without using a special tool.
