  • We know that humans are able to live comfortably when there is a balance between the living environment that surrounds us and us. Clothing, one of the necessities of life, serves a dual purpose of functioning as protection for the body as well as providing visual satisfaction, and so is the most effective bonding mechanism. A different type of comfort that has been provided through industrialization and advancements in technology has resulted in pollution problems in the environment, and it has reached a point of seriously thinking about its effects. The biggest problems in environmental pollution are air pollution and waste disposal, and something that cannot be ignored is that environmental hormones and harmful heavy metals have been discovered in the synthetic dyes used in the clothing product, and not only are they harmful to the body, but they also have adverse effects on skin allergies such as atopic dermatitis. Its effects on clothing, especially underwear and baby products, can become a serious issue. The use of natural vegetable dye can be considered the basis for the traditional Korean dyeing process, however not all natural dyeing process can be thought of as traditional Korean dyeing. This is because natural dyeing used to be the most common method of dyeing before synthetic dyes came along and became the dye of choice for most clothing. Natural dyes are beneficial to the body, and the nature colors, achieved from the natural materials, relieve eye strains as well as have a healing effect for people who are suffering from psychological instability such as stress. However, the use of mordant in order to increase the fastness and get better color effects can lead to even more damage to the environment, and it cannot be a dyeing method that is good for the body. Traditional natural dyeing is different from regular natural dyeing because it uses colors that the Korean people can identify with and applies specific methods in order to achieve those colors. Even though experimental study with dyestuff and practical use of the dyeing methods for traditional Korean dyeing has been started(Soh, H., 1983) and has been ongoing, it is still not easy for regular people to use the method on their own. At the present time, natural dye materials are getting made and sold more than ever, but there is a lot of confusion among consumers regarding the difference between traditional Korean dyeing and natural dyeing, as companies are using the two terms interchangeably to market their natural dye products. So getting a better understanding of the characteristics of traditional Korean dyeing and traditional colors should be considered first priority at this time. The purpose of this thesis is to study the traditional Korean view of color, which developed the culture of traditional dyeing in Korea, and the characteristics of traditional Korean dyeing, a method that pursued achieving Korea's color through natural dyeing.

  • Natural dyeing means coloring with dyes extracted from plants, minerals or animals found in nature. Natural dyeing provides calm and natural colors; it has antibacterial and deodorizing qualities; and the dyeing process is environmentally friendly. This study extracted natural dyes from young fruit by thinning out the superfluous fruits of Naju pear trees, and then examined its dyeing properties, the optimal dyeing conditions, and its color fastness for practical use. The results indicated that dyeing is ideal when it had Cu mordant treatment (5% concentration at 9$0^{\circ}C$, pH 4) for 50 min. The color fastness of natural dyes with Cu mordant treatment was very excellent after rubbing and dry cleaning, and also good after exposure to perspiration, light and washing.

  • Polygoum tinctoria dye is the one using the method of reducing dyeing, and so is made by the mechanism different from natural dye in general, and the reproductive dye is more difficult because it varies in accordance with manufacturing method and days being manufactured in case of natural indigo dye that has been used traditionally. In addition, overall analysis is short of color changes in accordance with natural dyeing condition and barely none of the research for cellulose system such as cotton in particular. Accordingly, this study tries to research on the natural dyeing method optimal for color development that is desirable in designing and development of natural dyeing as comparing and contemplating the change of dyeing quality and color in accordance with reduction temperature and time, reductant quantity, dyeing temperature and time, NaOH quantity, and dyeing repetition times in order to expand dyeing methods and use variously polygoum tinctoria by improving traditional dyeing methods as well as to establish exact dyeing method of cotton which is a fabric of cellulose system in order to make such polygoum tinctoria quantificated and reproductive. The optimum conditions in the dyeing procedure are as follows: Reducing temperature is $50^{\circ}C$. Added concentration of the reducing agent is $3g/{\ell}$. Reducing time is 30minutes. Dyeing temperature is $30^{\circ}C$. Added concentration of NaOH is $1g/{\ell}$. Dyeing time is 30minutes.

  • Coffee extract dyeing on silk fabric using various mordanting agents at different mordanting condition was studied in our previous research. Coffee extract dyeing can exert beautiful colors and have several advantages over the conventional natural dyeing. Since most of natural dyes are expensive for mass production, strongly season and source dependent, and hard to store, and therefore, coffee waste was used as natural dye to create beautiful colors in this study. Coffee waste is inexpensive and easy to store, and provide a comparatively regular quality regardless of season and source. The effects of dyeing condition such as dyeing temperature, dyeing time, and liquor ratio on dyeing characteristics of silk fabrics were investigated. Coffee extract dyed silk showed brilliant colors, and the colors were different with the kind of mordant. Cu, Sn, and Al mordanted silks showed golden yellow with subtle change of hue and value, while Fe mordanted silk showed a brownish green color upon coffee extract dyeing. As the dyeing temperature increased, the dyeability generally increased in all mordanted silk fabrics except Fe mordanted silk until $45^{\circ}C$. The dyeing temperature did not affect the dyeability of Fe mordanted silk fabric. As the liquor ratio increased, the dyeability showed a gradual increase in all mordanted silk except Cu mordanted silk. Cu mordanted silk fabric showed an abrupt increase in dyeability at liquor ratio1:150. The dyeing time effect can be separated into 2 stages. During the initial half an hour, the dyeability did not change significantly, and then, increased after 45 min. dyeing time duration. A further increase in dyeing time after 45 min. did not affect the dyeing efficiency in all mordanted silk fabrics except the Cu mordanted.

  • Black liquor staining for the development of natural color of bleached Hanji caused problems of discoloration and degradation. This study was carried out not only to complement these problems but also to develop natural dyeing method that was similar to the color of unbleached Hanji, through the dyeing of rice straw extractives. The dyeing properties of Hanji were influenced more by dyestuffs extraction method than extraction and dyeing time. Dyeing ability of hot water extractives was superior to cold-water extractives. Without the relation to the time of extraction and dyeing, the color of Hanji dyeing hot water extractives were similar to the control, and the color of Hanji dyed for 45 min with hot water extractives that extracted for 120 min, were almost same as the control. As natural dyestuffs, hot water extractives of rice straw showed that excellent dyeing ability for the development of various natural colors similar to unbleached Hanjis.

  • This study was carried out to investigate combination dyeing of the cationized cotton with natural colorants extracted from Gardenia and Sappan wood extract using methanol. To improve dyeing properties of cotton with natural dye, cotton fabric was preheated with cationizing agent containing chlorohydrine group in aqueous solution of sodium hydroxide. On the whole the various medium colors were developed by repeat dyeing with different colorants after dyeing with one colorant in case of natural dyeing, In this study, however in order to obtain various colors on cationized cotton fabrics with natural dyes, pre-mordanting and combination dyeing were carried out. The various colors were obtained according to various metal compounds for pre-mordants and various mixing portion of Gardenia and Sappan wood. Metal compounds containing alum, copper and iron were used for pre-mordants.

  • The purpose of this study was to investigate the dyeing properties of mugwort extract by nano-cellulose(n-cell). When dyeing cotton, rayon(artificial silk, called Ingyeon) and silk with mugwort extract, the difference with and without 2 wt% n-cell which it diluted to 0.6% treatment was compared. It was found that the addition of n-cell changed the values of L, -a(+red ~ -green), and b(+yellow ~ -blue) of all scoured cotton, rayon and silk fabrics, compared to dyeing only mugwort extract. Furthermore, it was confirmed that the ΔE and the K/S value slightly increased in all of the dyed cotton, rayon, and silk fabrics treated with n-cell at the same time as dyeing compared to the untreated ones. Therefore, by treating the fabric with n-cell, a natural cellulose component, at the same time as dyeing, it is expected to maintain stable fastness, which is a disadvantage of dyeing using natural dyes, and contribute to the utilization and commercialization of other natural dyes.
