Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of post-processing for improving the durability of a dyed dyed salt,

More particularly, the present invention relates to a process for post-treatment of a dyed dyed dyed salt, and more particularly, to a dyed dyed dyed dyed dyed product, So that productivity can be expected to be improved.

In general, impure dyeing is a process in which a tannin component contained in a substance is bonded to a fiber, and a tannin component bound to the fiber is gradually oxidized, polymerized and turned brown when exposed to sunlight.

It consists of 9 ~ 15% sugar, pectin, ascorbic acid and xanthophylls, and carotene and tannin, which gives a tangy taste. The tannin, a coloring component of the above components, is a generic term for various polyphenolic compounds The chemical structure is not clearly classified.

The tannin is colorless but brown when it is oxidized. It is a condensed condensate of derivatives of florboline. It is mostly contained in the immature part. It is oxidized by oxidation to anthocyanin and anthracanthine, and bitter taste and bitter taste disappear.

Contrary to hydrolyzed tannins, carbohydrates are mainly falvan-3-ol or favan-4,4-diol polymers, or a mixture of these two substances, in contrast to hydrolyzable tannins. Lt; / RTI > polymer.

These condensed tannins are not easily decomposed by acids but are polymerized to form amorphous phlobaphene or tanin-red. The condensed tannins of the respective plant foods are complex and varied in structure, .

The color development of the traditional persimmon extract dyeing fabric has been carried out for several days while imparting moisture to the dyeing fabric in daylight. As a method of industrial significance to overcome the problem of the amount and place of sunlight, there is a method of color development using ultraviolet rays There are many studies that sought for.

Under the conditions of color development, the basic system was a method of coloring by sunlight, coloring by ultraviolet light, coloring by heat, dyeing with fresh juice and developing sunlight.

Daylight coloring takes 7 to 10 days depending on the weather, and it is necessary to take a place. As a remedy, it is trying to dye ultraviolet rays with fresh juice in order to color more quickly.

Examination of the prior art concerning dyestuff dyeing has disclosed a patent application No. 10-2001-0073053 entitled " Natural Extraction Method and Natural Dyeing System for Dyeing "(Patent Document 1) and Patent Application No. 10-2002-0013583 (Patent Document 2), and Patent Application No. 10-2010-00138955 entitled " Avalanche Dyeing Machine "(Patent Document 3).

In consideration of the technical contents of Patent Document 1, in order to extract a large amount of juice dyes from persimmon leaves and fruit and to extract an effective juice extract, a persimmon leaf or fruit selected in a large capacity rotary mixer tank is put and rotated, In the case of persimmon leaves, it is extracted at a room temperature for a certain time in a persimmon leaf extraction tank containing a fibrotic decomposition organic substance, and after passing through a pigment filtration concentration tank with a built-in impurity filtration filter A colorant stabilizer is added to the extract to reduce the color change of the mixture. The concentration of the colorant and the concentration of the colorant stabilizer are added to reduce the concentration of the colorant. Next, if you dampen raw materials and cotton fabrics in a dye tank that causes water waves, And the dyeing dye is allowed to penetrate into the texture of the fiber. The dyed cotton fabric is irradiated and dried according to the concentration of the dye in the UV lamp drying dark room, and then the dye is precipitated in a tank containing the dye fixing solution, Followed by final drying.

When the technical contents of Patent Document 2 are examined, the juice is pulverized into a juice powder, and the juice is prepared by dissolving the juice in water at 3 to 20% by weight. 100%, and then irradiated with an artificial light source to develop color.

The technical content of Patent Document 3 includes a tank for containing the scouring saline solution, a frame attached to and supported on the outer surface of the tank, and a presser mounted on the front of the tank for dehydrating the scouring saline absorbed in the screed, The tank includes a tubular body having an inlet and an outlet through which the fabric enters and exits from an upper portion of a front side thereof, a heater pipe arranged side by side on one inner side surface formed inside the body and circulating the steam, A circulation roller supported on the inner surface of the body so as to be rotated to circulate the fabric and to rotate the circulation roller so as to be parallel to the front or rear of the circulation roller; And a motor attached to the body for driving the circulation roller and the auxiliary roller Gammul that relates to the dyeing.

Therefore, in the case of Patent Documents 1 and 2, the use of an artificial light source using a UV lamp drying dark room or near ultraviolet as a main wavelength is used as a means for expressing color on a dyed material to which a juice is adsorbed, But also the dyeing fastness was somewhat lowered.

In the case of Patent Document 3, the process of hand-dyeing, which was performed manually by a workshop, was mechanized, and the manual dyeing was discontinued, but the principle of dyeing was not out of the principle of dyestuff dyeing conventionally practiced conventionally.

In Patent Documents 1 to 3, preparations for use in makeup dyeing are prepared by adding an appropriate amount of water to the juice or juice powder so that the juice is dyed. However, unlike natural dyes, It is colored and becomes brown. It takes a lot of time and space to pass through the color development process, and there is a disadvantage that dyeing property and dyeing fastness are deteriorated.

As means for solving such disadvantages, the inventor of the present invention has found that dyeing is carried out by gradually adding alkali and acid to juice to reduce coloring time, dyeing fastness and coloring time, Method.

However, the above dyed substances have a tendency to accelerate oxidative coloration in the dyeing process of juice and change to hypercholesterolemia. When the coloring is progressed, the binding force with the fiber is lowered.

Patent Application No. 10-2001-0073053 entitled " Natural Extraction Method and Natural Dyeing Automation System for Dyeing " Patent Application No. 10-2002-0013583 entitled " Method for producing natural juice dye using bubble powder and artificial light source " Patent Application No. 10-2010-00138955 entitled "

It is an object of the present invention to improve the dyeability and color fastness of an object affixed to a dyed material, and to improve the productivity by reducing color development time.

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

The method for post-treatment of a dyed dyed salt for improvement of durability to be provided in the present invention is characterized in that the dyed dyeing step (S1), the preliminary drying step (S2), the steam treatment step (S3), the drying step (S4) (S5), a water washing step (S6), and a drying step (S7) may be added as necessary.

The dyed material to be applied to the present invention can be applied to materials having affinity with dyed substances such as cotton fabrics and silk fabrics.

In the present invention, a cotton fabric material was used.

The process of dyeing is as follows.

In the affirmative dyeing process (S1), a known process or a brief process is carried out. After adjusting the pH to 11 to 12 by adding 0.8 L of NaOH to 20 liters of the impregnated product, the product is heated to 80 to 90 DEG C, After cooling, 1.6 L of citric acid is added to the cooled impurities to give a pH of 5 to 6 to obtain a dyed impression.

The dyed impression is put into a dyeing tank at a bath ratio of 1:40, and the temperature is raised to 80 to 90 ° C. The dyed goods are dipped in a dyed product (cotton product) for 5 to 10 minutes, (S1) is completed by removing the excessively adsorbed impurities and causing the impurities to be uniformly adsorbed on the organisms.

After the adsorption of the impurities on the dyed material is completed, the preliminary drying step (S2) is performed.

The preliminary drying step (S2) is to improve the efficiency of the steam treatment process by drying the dyed material adsorbed by the scouring material at an appropriate moisture content.

In this case, the temperature of the cylinder is transferred at a temperature of about 100 ° C. and the conveying speed is 1 to 2 m to transfer the dyed article to the dyed article Preliminary drying is carried out so that the residual amount of the immersion salt, that is, the water content is maintained at 10 to 30%.

After the preliminary drying step (S2), the dyed material is subjected to a steam treatment step (S3) for enhancing the salt-bonding strength and for firmly fixing the dyed material to the dyed material.

The steam processing step (S3) is as follows.

Preliminarily drying the dyed material with a moisture content of 10 to 30%, steam is gradually passed through the steam treatment chamber where the steam is sprayed, so that the dyed dyed material is firmly fixed to the dyed material.

The reason why the dyed dyed dyed materials are steam-treated is that the alkali added during the production of the dyestuffs undergoes structural transformation through the tannin and hydrolysis of the sensuous component, thereby losing the properties of the condensed tannin and changing into ordinary tannin. In this process, And the color of the color changes to hyper color. If the color develops much, the bonding force with the fiber gradually weakens, so that the steam treatment step (S3) is required.

The temperature condition of the steam treatment room is treated at 90 ~ 110 ℃ for 15 ~ 20 minutes to improve the durability, so that the dirt is fixed firmly to the dirt.

The dyes that have undergone the steam treatment step (S3) under the above conditions dry the dyes through a drying step (S4) comprising a normal cylinder drying or a hot air drying.

The dyed material dried in the above step is subjected to a far end retention step (S5). In the far end retention step (S5), the properly dried dyed material remains in the retention tank for a certain period of time, (The far-end stagnating step S5 may be omitted)

The dyed material that has undergone the far-end retention process (S5) is washed through the water-washing process (S6).

It is preferable that the dirty water is washed through the spray nozzle in the water washing step (S6), and the washing water is washed at room temperature of 20 to 25 DEG C.

If the temperature of the washing water is higher than 25 ° C, the dye swells due to the temperature rise and the dye that has adhered to the fibers at the same time as the swelling of the fiber occurs. If the temperature is low, the dye attached to the surface of the dye is not sufficiently washed It is not desirable because of concern.

When the water washing step (S6) is completed under the same conditions as described above, the drying step is performed.

The drying process (S7) uses a composite drying system in which hot air drying and infrared drying are mixed. When the dyed material is thin, the fabric is dried at 110 ~ 130 ℃, when it is thick, it is dried at 160 ~ 170 ℃ and then the fabric is wound.

If only the hot air drying is used in the drying step, there may be a risk of line-shaped scratches on the dyed material, and if the drying is only infrared drying, incomplete drying may occur.

As described above, according to the present invention, the dyed dyestuff is dyed with a dyeing agent, and the dyestuff is stuck to the dyed material by enhancing the dyestuff through the steam treatment process. Also, 20 to 25 ° C), so that it is possible to achieve effective depilatory dyeing. In addition, the process can be mechanized so that the continuous treatment can be performed, so that the productivity of dyed goods can be improved .
