Description

Gradation Dyeing Method [

The present invention relates to a gradation dyeing method, and more particularly, to a gradation dyeing method of dying a color or a picture gradually from a dark color to a fabric.

Generally, the method of dyeing the fabric is divided into several kinds according to the kinds of the fibers and the dyes. In a large scale, there are two types of dyeing: dyeing (dyeing) and printing (printing).

Dipping is a method of immersing dyed dyes while rotating the dyed dyes partially in a dyeing solution.

The types of fibers to be dyed include yarns, fabrics, knitted fabrics, and the most common ones are fabrics and knitted fabrics.

During dipping, post-dyed fabric is made from fabric and then dyed in the form of a piece, which is also referred to as an igneous dye by dyeing the entire fabric in one color. Dyeing is done by using dyes that have different dyability of synthetic fibers that are not plain solid, and they are also used to make mixes and plaids.

Printing is also used for paper and other materials, but it is a technique for coloring yarns and fabrics, especially fabrics, to make necessary patterns appear. Printing is divided into hand printing, auto screen and rotary screen printing.

Hand printing is a method of applying a waterproof coating on another part of a screen, leaving the pattern on the screen, using the number of colors as the frame, and moving the person with the screen and spatula in the order of color.

The operation of putting on the frame or moving the color of the print printing should be done entirely by human hands.

Auto screen has the same principle as hand printing, but can be operated automatically by machine. The other thing is that the screen is lined up by the number of colors, and the screen moves closer to the screen while moving downward.

The rotatory screen uses a circular metal screen with many holes to allow colors to penetrate inside the cylinder and move the mold to allow the dye to run on the cloth.

In the conventional dyeing method as described above, dyeing can be performed when a fabric is dyed with only a single color or woven using yarns having different characteristics.

In addition, even if polychromatic dyeing is possible, it is necessary to perform multiple dyes to dye multiple colors, since each dyeing operation is required for each color used for dyeing various colors.

Therefore, fabrics woven with yarns of the same characteristics could not be dyed in two colors. In case of multicolor dyeing, the process of dyeing the fabrics was complicated because it had to be processed several times, and the time, labor, work space, Was consumed excessively.

For example, Patent Document 1 below discloses a 'dyeing method of a fabric'.

The method of dyeing a fabric according to the following patent document 1 includes a step of immersing the fabric in a juice emulsified with persimmon to dye the dyed fabric, a step of immersing the fabric in the juice immersion step, A pattern forming step of forming a pattern so as to concentrate the juice which is immersed in the patterned portion by performing a folding operation on the fabric in a state of infiltrating the juice into the fabric in the infiltrating step of the juice, A drying step of performing drying by exposing the juice to the sunlight in a state where the juice is concentrated on the side of the pattern in the forming step, the drying is performed in the drying step, the moisture is added while adjusting the amount of sunlight, A coloring step of coloring by controlling the concentration of the tannin component of the impurity, Wherein the drying step is a step of drying the fabric so as to make the juice adhere while displacing both sides of the fabric developed in the color step to complete the drying, A second dyeing step of infiltrating particles of a permeable natural dye into a second part of the second dyeing step, and a dyeing step of drying the second dyeing step in a state where the second dyeing step is infiltrated to complete dyeing.

The following Patent Document 2 discloses a natural dyeing method with improved fastness and natural fabrics using the same.

Referring to FIG. 4, a method of gradation dyeing according to a preferred embodiment of the present invention will be described in detail.

4 is a process diagram for explaining a gradation dyeing method according to a preferred embodiment of the present invention step by step.

As shown in Figs. 1 to 4, the main body 10 opens the first opening / closing valve 22a of the water pipe 22 to store the water. At this time, the water is filled to about 85 to 95% of the capacity of the main body 10. This water is filled with the water tube 24 at an appropriate height while being observed from the outside. On the other hand, in the water tube 24, it is possible to more accurately grasp the storage amount of the water by forming a scale at regular intervals so as to easily grasp the storage amount of the water.

In addition, a color dye to be dyed is stored in the dye container 21. The dye in the dye bottle 21 is supplied to the main body 10 by the rotation of the circulation pump 26 while being supplied according to the opening of the opening and closing valve, and a dye mixture is formed in which water and dye are mixed (S10).

On the other hand, while the dye in the dye bottle 21 is continuously supplied, the hot water heated in the hot water supply device 23 is circulated through the spiral tube 23a and the temperature of the dye mixture is raised to 50 to 80 ° C by hot water (S20) .

At this time, the temperature of the dye mixture can be checked by the temperature sensor 25.

On the other hand, the object to be stained is fixed to the rotating body (30). The object to be stained is fixed between the upper frame 32 and the lower frame 33. The object to be stained is fixed to the hook 34 of the upper frame 32 and the hook 34 of the lower frame 33, Is helically wound and fixed when viewed from the plane.

The reason for spirally winding the object to be dyed is to make the intervals of the objects to be dyed fall at a constant interval to widen the contact area with the dye mixture to secure a sufficient contact area.

At this time, the rotating body 30 is lifted up to the upper side of the main body 10 to fix the object to be stained. A hoist (not shown) or the like is provided on the upper side of the rotating body 30. Thus, the rotating body 30 fixes the object to be stained at a position raised by a hoist or the like.

When the fixing of the object to be stained is completed, the rotating body 30 is lowered by the hoist or the like and put into the main body 10 (S30).

The lower end of the rotating rod 31 is rotatably coupled to the hub 11 of the main body 10 as the rotating body 30 is lowered. Further, the fixing frame 37 is fixed to the upper side of the rotation bar 31, and the rotation bar 31 is maintained to be vertically fixed. The power transmission means 36 such as a chain or a belt is connected to the rotation shaft 31 and the drive motor 35.

By driving the driving motor 35, the rotating body 30 performs the first staining while rotating the object to be stained (S40).

The operator checks the state of dyeing with the naked eye and opens the opening / closing valve 12a of the drain pipe 12 over a period of time of about 4 to 7 minutes after the rotation of the rotating body 30, For example, approximately 10% is slowly discharged.

By gradually discharging in this manner, the dyeing object is subjected to dyeing while continuously increasing the difference in density of the dyeing. That is, in order to stain the color of the object to be dyed with increasing saturation or lightness while moving from the upper part to the middle part of the object to be dyed.

That is, the upper portion of the object to be stained has a low dyeing time and a low concentration of the dye mixture in the dye mixture, and the dyeing is performed at a lower density than the subsequent second and third dyeing steps.

The dye mixture remaining in the main body 10 is continuously circulated by the circulation pump 26, and the dye is continuously supplied to the dye bottle 21 in an open state. As a result, the dye mixture is converted into a dye mixture having a higher concentration as the dye is continuously supplied.

In addition, the dye mixture is maintained at a temperature of about 50 to 80 ° C by the spiral tube 23a, and the second dyeing of the dyeing object is performed by the heated dye mixture (S50).

On the other hand, the open / close valve 12a of the water discharge pipe 12 is maintained in an open state, and the open / close valve 12a is adjusted to be discharged in a small amount. Therefore, the dye mixture liquid is gradually drained from the main body 10.

As the dye mixture is gradually discharged over time, the concentration of the dye mixture becomes thicker due to the dye to be added, and the dyeing concentration of the dyeing object becomes longer than that of the first dyeing step It becomes thick.

That is, as the dye mixture is discharged, the contact height between the dye mixture and the dyeing object is gradually lowered, and the dyeing density of the dyeing object gradually becomes thicker.

When the level of the dye mixture is lowered to a height of 45 to 55% of the height of the main body 10, the hot water supply device 23 heats the hot water to a high temperature and circulates the hot water through the spiral tube 23a, The temperature is raised to 95 ° C.

This is to raise the temperature of the dye mixture to improve dyeing and to increase the dyeing density. In addition, the circulation pump 26 continuously circulates the dye mixture in the main body 10, and the dye stored in the dye container 21 is continuously supplied. Accordingly, the concentration of the dye mixture becomes thicker, the temperature rise and concentration of the dye mixture becomes thicker and darker, and the dyeing density of the dyeing object becomes gradually thicker as the dyeing time becomes longer S60).

In this third dyeing step, the dye mixture is discharged and the level of the dye mixture is gradually lowered, so that the dyeing is performed at a concentration which becomes thicker than the second dyeing step.

When all of the dye is put into the dye container 21, the opening and closing valve of the dye pipe 27 is closed to stop the supply of the dye. The closing of the dye container 21 may be blocked in advance during dyeing, if necessary. That is, it is possible to increase the temperature of the dye mixture and increase the dyeing time, thereby increasing the dyeing concentration.

As such, the dyeing is continuously performed, and the dyeing (gradation) is performed in which the concentration of the dyeing object gradually increases in accordance with the level, concentration, and time of the dyeing object and the dye mixture.

On the other hand, when the water level of the dye mixture is lowered to a height of about 5 to 15%, the supply of hot water is stopped in the hot water supply device 23, And the dye mixture is discharged (S70).

After dyeing, the dyeing object is washed, then treated with a softening agent, and dried. Since the step after the washing process is a normal process, a detailed description thereof will be omitted.

On the other hand, at the time of cleaning the main body 10, the first opening / closing valve 22a of the water pipe 22 is opened to the main body 10 from which the dye mixture is drained, and the main body 10 is cleaned do.

Then, the cleaned main body 10 opens the second open / close valve 22b of the water pipe 22 to discharge the water. The first on-off valve 22a is opened and the second on-off valve 22b is closed. When the water is discharged, the first on-off valve 22a is closed and the second on- Lt; / RTI >
