With the rapid development of synthetic fibers and synthetic dyes, humankind is making progress in living a rich and rich life. However, in recent years, the increase of people's living income and the hygienic and comfortable environment are required, and natural fiber having excellent advantages in hygroscopicity and wearing comfort, antibacterial and deodorant. There is a growing interest in natural dyes having excellent pharmacological effects such as sex, anti-cancer and anti-allergic properties.

  Natural dyes, which accounted for less than 1% of the world's total production of dyes, are highly valued and highly value-added industries that have been highly demanded by consumers, and the eco-friendly dyeing process has recently been in the spotlight in line with national policies to pursue a clean environment. The situation is increasing in terms of usage and usage.

  However, it is very cumbersome to extract the dye from each dyeing material at every dyeing, and the storage of the extracted salt solution is not easy, so the salt solution may rot in the summer when the temperature rises or the humidity is high. Therefore, in order to solve these drawbacks, it is necessary to prepare a dye concentrate or dye powder to establish a method that can be more easily reproduced and easily dyed.

  In the past, natural dye production was markedly low due to the lack of people's awareness and technical skills, and only a few craftsmen and research institutes have been able to connect it. In addition, it was difficult to mass-produce and industrialize despite the advantages of environmentally friendly natural dyes due to the disadvantages of poor clarity, poor daylight and washing fastness, and easily cause salt spots. In recent years, active research on natural dyes has been carried out due to the poor and small-scale production environment being gradually improved and overall social awareness. Among them, natural dyes are powdered, making it easy to store and minimizing dye degradation due to temperature and humidity. As a result, reproducibility was improved, and dyeing and mixing of heterogeneous dyes at a certain ratio were possible, so that color diversity could be achieved and sharpness was also improved. In addition, the use of a mordant at an appropriate concentration, together with the quantitative use of the dye, has contributed to the improvement of various fastnesses.

  On the other hand, the dyeing industry is a representative industry of the water industry type, and after the dyeing process using general synthetic dyes using a large amount of water, a large amount of residual dyes and additives are generated as dyeing wastewater, which is not easy to remove. . Therefore, it causes serious damage to various organisms and causes serious environmental pollution. However, dyes with natural dyes are more traditional than dyes with synthetic dyes and can produce high value-added products with their natural colors, and they are generally harmless to humans and the environment and are environmentally friendly throughout the dyeing and dyeing processes. And interest in the dyeing process is increasing day by day.

  In addition, most natural dyes have pharmacological effects and edible ones as the herbal medicines, and they are receiving a lot of attention in terms of health promotion for consumers, and the advanced recognition of herbal medicines makes the natural dyes industry more valuable.

  The interest in natural dyes is of interest to the world, including Korea, Japan, China, Asia, the United States, Europe, etc., and research on pruning, safflower, joiner, gardenia, turmeric, yellow wall, etc. has been actively conducted.

Such natural dyes include polychromatic dyes in which the color of the dye is changed by mordant and monochromatic dyes, which are expected to improve the limited color expression, which is pointed out as one of the disadvantages of natural dyes. Doing. Ogapi has excellent pharmacological action and is known to have effects such as antimicrobial, deodorant, and anticancer properties, and has been widely consumed. There is a demand for a method of expressing the pharmacological effect of the organza by applying the natural material of the organza, especially the high-grade silk fabric.

In addition, the reagent used in the mordant was used as a first-class reagent without purification, and the chemical names and structural formulas of the aluminum, copper, chromium, iron, and tin metal compounds used as mordants are shown in Table 2.

Mordant Chemical name constitutional formula Al Aluminum potassium sulfate AlK (SO ₄ ) ₂ 12H ₂ O Cu Copper (II) sulfate CuSO ₄ 5H ₂ O Cr Chromium potassium sulfate CrK (SO ₄ ) ₂ 12H ₂ O Fe Iron (II) sulfate FeSO ₄ 7H ₂ O Sn Tin (II) chloride anhydrous SnCl ₂

According to the above conditions, first, dyeing for 60 minutes by changing the dye concentration from 50 to 400% (owf) at a bath ratio 1: 100, 60 ℃ in order to determine the Ogapi powder dye and temperature.

In addition, in order to find out the optimal dyeing time of the Ogapi powder dye, dye concentration 250%, bath 1: 100, dyeing temperature is dyed for 10 to 120 minutes at 40, 60, 80 ℃.

In addition, by using the mordant at a predetermined concentration with a bath ratio of 1: 100 by dyeing pre- and post-mordant method to determine the effect of each mordant on the dyeing.

Looking at the results for each of the above conditions, first, the effect of the amount of Ogapi powder on the dyeability is as follows. In order to investigate the affinity for the silk fiber of Ogapi powder dye in the untreated state, the dye concentration was changed from 50 to 400% (owf) at 40, 60 and 80 degrees, and the dyeing ratio was 1: 100 and 60 minutes. The result of measuring the dye concentration is shown in FIG. 1.

The dyeing concentration (dyeing rate) was measured using a UV-visible spectrophotometer (X-Rite, SP68 spectrophotometer, USA) equipped with an integrating sphere to measure the surface reflectance of the dyeing product, and the K / S value was measured by Kubelka-Munk equation. The dyeing amount was evaluated by calculating.

K / S = (1-R) 2 / 2R

here,

K: Absorption coefficient of dye cloth, proportional to concentration

R: reflectance of monochromatic light from dyeing cloth

S: scattering coefficient

As the dyeing temperature is increased as shown in FIG. 1, the dyeing concentration increased, and the dye concentration was 250% or more, and the increase was slowed down, and the optimal concentration of the dye was 250% or less.

Figure 2 is measured the dyeing concentration of the sample dyed for 10 to 120 minutes at a dye concentration of 250% (owf) at 40, 60, 80 degrees in order to determine the optimal dyeing time of the Ogapi powder dye in the untreated mordant situation The results are shown. As shown in Fig. 2, the dyeing concentration increased as the dyeing time increased, and when the dyeing time was 40 degrees and 60 degrees, the increase in dyeing amount was slowed after 40 minutes. It can be seen that the dyeing amount increases. Therefore, the dyeing process is preferably performed in the range of 60 to 80 degrees as a range of the temperature of the silk fabric intact. When the dyeing is carried out under the conditions of 80 degrees or more, there is a problem in that the design of the color of the silk fiber is damaged and the dyeing rate is increased.

Figure 3a to 3e shows the result of measuring the dyeing concentration in each mordant dyeing by pre- and post mordant method for 30 minutes at a bath ratio 1: 100, 60 degrees using five mordant agents. The powder concentration was set at 250% (owf), 60 degrees, and 60 minute bath ratio 1: 100.

The dyeing concentration of Fe, Sn was relatively higher than that of Al, Cu, Cr printing, and the dyeing concentration was significantly higher than that of post-printing.

Example

The organo pigment powder to be used is pulverized 100 g of organo, mixed with 6 liters of ethanol and left to stir for 12 hours, and the dye extract obtained by filtration is concentrated under reduced pressure using a rotary distillation machine to obtain a dye powder using a spray-dryer.

Color fastness measurement

As a mordant, use 5% (owf) of alum, 3% (owf) of copper sulfate, 1% (owf) of chromium alumina, 1% (owf) of ferrous sulfate, and 1% (owf) of tin tin. As a result of measuring various fastnesses of samples obtained by dyeing (60 degrees, 30 minutes, bath ratio 1: 100) and dyeing (dye powder 250% owf, 80 degrees, 60 minutes, bath ratio 1: 100), , Washing fastness was not good as grade 2 to 3, but this is considered to be a characteristic of silk fiber, dry cleaning fastness was generally excellent in grades 4 to 5 and sweat fastness and friction fastness were good.

Antimicrobial Measurement

Staphylococcus aureus ATCC NO. 6538P as a test bacterium (Table 14) describes the antimicrobial effect on silk fabrics dyed with pigment powder extracted from Korean ginseng. The microbial reduction rate of untreated silk was very low at 11.6%, which is not an effective microbial reduction rate. Cr-treated silk fabrics showed a relatively high bacterial reduction rate (70.9%), and in other cases, Al, Cu, Fe, Sn-embedded silk fabrics showed excellent antibacterial effect with a 99.9% bacterial reduction rate. In addition, only 99.9% of the dyed silk fabrics showed a high bacterial reduction rate, and 99.9% of the dyed silk fabrics were stained with Al, Cu, Cr, Fe, and Sn.

Deodorant rating

In the deodorizing experiment, the decay rate of ammonia gas was judged to be almost the same as that of human odor. The deodorization rate of untreated silk was about 50%, but the deodorization of prestained dyed silk was 98.5% after 30 minutes and 99.5% after 120 minutes. After 30 minutes, 88% and after 120 minutes, 98%, the deodorant was excellent, and even when stained without embedding, it was 91% after 30 minutes and 96% after 120 minutes. .

As described above, the silk fabric dyed by using the Ogapi extract according to the embodiment of the present invention has excellent fastness and excellent antibacterial and deodorizing function.                     

In addition, by suggesting the optimum conditions for dyeing the silk fabric, it is possible to impart functionality as a dyeing process without a separate antibacterial process or additives while minimizing damage to the silk fabric has the feature that the productivity can be greatly improved.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
