Description

Extraction method of persimmon juice for natural dyeing and automatic dyeing system

The present invention relates to a natural dyeing agent and a natural dyeing automation system mainly composed of persimmon leaves and persimmon, and more particularly, to prevent discoloration and discoloration of natural dyeing through a series of post-treatment processes of natural pigments extracted from persimmon leaves and fruits. The present invention relates to an automated system of natural dyeing for color diversification and mass production, and thus to a cheap mass production of expensive natural dyes.

Generally, persimmon (Diospyros Kaki) is a deciduous arborescent tree with eight tastes and sweetness, and is distributed anywhere in the world such as tropical, subtropical and temperate, and classified into sweet persimmon and eight persimmon used for food.

Persimmons are very green when they are green, but the juice squeezed out is called persimmon, which is effective for antiseptic, moisture-proof, and convergence. Persimmons were painted on paper and used as fan-making papers. Persimmons have been used as natural dyes, depending on the tanning and fat of leather.

In addition, persimmons were crushed to extract juice in July and August, and this juice was used as a salt solution without storing water and used as a salt solution, and when used immediately, water was mixed.

After absorbing the juice, the dregs are dropped and spreaded and dried under direct sunlight to develop the color. At this time, the water is reduced or the persimmon is reduced and dried over 10 times under direct sunlight, and then dyed to dark brown. It appears to be fed and is very dry right after dyeing, but as you wear it, it becomes softer and becomes more brown.

However, conventional dyeing and dyeing methods using persimmon leaves and fruits are completely dependent on manual and natural light drying, resulting in a lack of pigment variety, instability of pigments, low pigmentation rate, irrationality of dyeing and dyeing processes, and low There is a problem with high defects such as productivity, discoloration and discoloration.

In addition, the general infectious color is immersed in the infectious solution, squeezed and oxidized to the desired color through 3 to 5 repeated dyeings during 7 to 10 days of drying under sunlight. In this process, the color of the infected color is determined according to the amount of tannin in the juice, the amount of the infected solution attached and the number of days of drying. However, there is a problem that the condition of the color development has almost no color reproducibility which is the biggest disadvantage of natural dyeing.

Accordingly, an object of the present invention is to provide a fastness in fastening dyeing conditions of natural dyes for cellulose-based and protein-based fibers in order to establish traditional dyeing techniques.

The present invention for achieving the above object is very small particles in the case of persimmon fruit after rotating the persimmon leaf or fruit selected in a large-volume rotary mixer tank for extracting a large amount of juice dyes and effective juice extraction from persimmon leaf and fruit Persimmon leaf was extracted from the persimmon leaf by extracting the juice from the persimmon leaf in a persimmon leaf pigment extraction tank containing fibrinolytic organic agent at room temperature for a certain period of time. A pigment stabilizer that prevents color change is added to the concentrated solution of the concentrated pigment in the stock solution or a certain amount of water so that the density of the color tone can be variously reproduced according to the concentration of the reduced solution and the ratio of the color stabilizer. Dip the dye-reducing raw material and cotton fabric into the dyeing tank that causes the waves, It has the same effect as kneading, so that the dye dye can penetrate into the tissue of the fiber, and the dyed cotton fabric is irradiated in the UV lamp drying dark to the concentration of the dye, and then precipitated in the tank containing the dye fixing liquid. By providing a system which is characterized by washing and final drying.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows an automated process system according to the present invention.

The method of extracting the juice of the present invention selects the persimmon leaf and the heat medium stored in the storage tank (1) for the extraction of a large amount of juice dye and persimmon extract from the persimmon leaf and the heat medium in a large capacity rotary mixer tank (2) The persimmon leaf or the heat-sensitive fruit is inserted and rotated. In the case of the heat-sensitive fruit, the crushed liquid is put into a press-compression tank (3) to extract the juice, and in the case of the persimmon leaf, the persimmon leaf pigment extraction tank containing the fibrinolytic organic agent ( 4) is extracted at room temperature for a certain time and is extracted through a pigment filtration concentration tank (5) with an impurity filtration filter (not shown).

In addition, the system for processing the fabric by extracting the juice solution as described above is the juice of the juice solution in the stock solution / mixed tank (6) mixed with the juice extract or concentrated water extracted persimmon leaf concentrated pigment extracted through the impurity filtration filter According to the density | concentration, the pigment | dye stabilizer 7 which is fixed in order to prevent natural discoloration and discoloration of the natural color tone of tannin which is a main component of a juicy pigment | dye is added,

Depending on the concentration of the juice and the ratio of the addition of the color stabilizer (7) has a characteristic that can reproduce a variety of tannins inherent,

The pigments are placed deep into the fiber tissue by the water wave movement in the tank, which is put in the dyeing water wave tank 8 and settles the juicy dyeing cotton fabric in the water wave tank 8 for a predetermined time and kneading by hand. Infiltrate,
