This study explored Jeju natural resources with healing function and tried mixed dyeing of Ecklonia cava and onion shell to improve dyeing. The results showed that silk dyed with a mixture of Ecklonia cava powder and onion shells rather than Jeju's individually dyed silk had better color power to develop fashion products. In addition, all friction lightning bolts, dry cleaning and sweat mining levels were excellent as well as excellent UV protection rates. The three baenaet jeogori worn during a birth anniversary and four rest suits that infants and children can wear comfortably maintained the dyeing and functioning of Ecklonia cava and onion shell mixture that was proven through abnormal experiments. For the three baenaet jeogori and two rest suits, the company has developed a fashion product recognized for high value-added merchandise using a variegation dyeing method made in a handmade style for expressing a person's natural sensibility through dyeing fabrics. Based on the results of the above research, it is expected that various fashion product developments will be possible by dyeing a mixture of functional and colorful extracts of the drug and colorful dye.

In this study, the dyeing of Chrysanthemum indicum Linne alone and the combined dyeing of Chrysanthemum indicum Linne and onion shell were first performed to compare dyeing properties. A combination extract of Chrysanthemum indicum Linne and onion shell can be expected to improve coloration. A Hanbok design for children used a natural dyeing fashion dyeing method to make the Chrysanthemum pattern. Chrysanthemum indicum Linne is a type of wild chrysanthemum with various medicinal effects for headache and stress relief, skin diseases, insomnia and depression. Widely used onion shells have medicinal properties that help prevent and treat various adult diseases. The colors of silk dyed exclusively by Chrysanthemum indicum Linne, and the colors of silk dyed by Chrysanthemum indicum Linne and onion shell extract are yellow; in addition, silk dyed by Chrysanthemum indicum Linne and onion shell extracts were almost all unchanged. Four hanboks, which are comfortable for children to wear and use, were produced using Chrysanthemum indicum Linne and onion shell extracts. If children wear hanbok fashion products with auspicious patterns, they can provide a chance to simultaneously experience the traditional symbolism of Korean patterns and culture. In addition, it is expected to develop pride in traditional dress culture.

The objective of this study is to develop eco-friendly, functional towel material utilizing cotton-Modal-chitosan blended(C-M-CH) yarn and natural dyeing with mugwort colorants. Dyeing properties of towels with mugwort colorants were studied by investigating the effect of dyeing conditions including concentration of mugwort colorants, dyeing temperature, and dyeing time, and the effects of mordants on dye uptakes were investigated. The C-M-CH towel showed better dye uptake than 100% cotton towel with mugwort colorants. The shade of towels got darker and red-yellowish tint increased by mordanting. Comparing with 100% cotton towel, the colorfastness of dyed C-M-CH towel was satisfactory showing above 3 grade which is the lowest grade to washing fastness. The antibacterial activity against Staphylococcus aureus and deodorization performance of towels were excellent and improved by dyeing with mugwort colorants. From the results obtained, it is concluded that the cotton-Modal-chitosan blended towel dyed with mugwort colorants can be used practically for an eco-friendly and multi-functional towel materials with excellent absorbance and drying properties.

Agricultural drainage salt generated during irrigation of crops in San Joaquin Valley, California, exceeds 600,000 tons annually and cumulates in the field in a rapid rate. As a result, the waste is taking out more farmlands for salt storage and disposal, imposing serious concerns to environment and local agricultural industry. In searching for a potential solution to reduce or eliminate the waste, this research explored feasibility of producing a value-added product, sodium sulfate, from the waste and utilizing the product in textile dyeing. The results indicated that sodium sulfate could be produced from the salt and could be purified by a recrystallization method in a temperature range within the highest and lowest daily temperatures in summer in the valley. The recovered sodium sulfate samples, with purities ranging from 67% to 99.91, were compared with commercially available sodium sulfate in the dyeing of levelling dyes. In nylon fabrics, the salt samples had little color difference in the dyeing with C.I. Acid Yellow 23 and C.I. Acid Blue 158. All salt samples' gray scale was 5 grade. In wool fabrics, the salt samples had little color difference in dyeing with C.I. Acid Yellow 23 and C.I. Arid Blue 158. All salt samples' gray scale was 5 grade. Generally, the dyeing of levelling dyes using recovered salts from farm drainage had little color difference than the dyeing of levelling dyes using commercial sodium sulfate.

The recovered sodium sulfate samples, with purities ranging from 67% to 99.91, were compared with commercially available sodium sulfate in direct dyeing of cotton fabrics. The salt samples recovered from Mendata, California (〉98.8% sodium sulfate) cause little color difference in the dyeing with selected direct dyes, and the purified salt (Ⅲ) (99.91% sodium sulfate) is more applicable for direct dyeing of cotton fabrics if it has no other toxic effects. The recovered sodium sulfate from certain areas in the valley could not be employed in direct dyeing due to the high level of impurities in it.

This study was carried out to investigate dyeing characteristics of CDP(cation dyeable polyester)/silk knitted fabrics with disperse type cation dyes/acid dyes by one bath dyeing method in comparison with two bath dyeing method in the interests for rationalization of the dyeing process. The apparent color depth(K/S) of the disperse type cation dyes with CDP and that of acid dyes with silk decreased slowly with increasing pH values of dyebath with the exception of sharp decrease at alkali region for CDP. The contamination behavior of CDP by the acid dyes and that of silk by the disperse type cation dyes decreased with progressing of dyeing. The migration ratio(%) of the disperse type cation dyes with CDP is low compared with that of acid dyes with silk. The sediment in mixed dying solution of disperse type cation dyes and acid dyes remarkably less compared with that of regular type cation dyes and acid dyes at $100^{\circ}C$ regardless applying of preventer agent of precipitation. When CDP/silk knitted fabrics was dyed with by with mixtures of disperse type cation dyes/acid dyes one bath or two bath dyeing method, the characteristic of reflectance spectra of CDP components were greatly influenced by disperse type cation dyes and that of silk components by acid dyes. It was confirmed that K/S values of each components of CDP/silk knitted fabrics dyed by one bath dyeing method decreased slightly compared with two bath dyeing method.

Bamboo leaves, as natural dye provide unartificial fresh green, are known for expert property at anti-bacterial, anti-aging, anti-oxidation, skin whitening, moisturizing, peeling of horny, deodorizing and some skin disease like as eczema and inflammation without any allergic response. Also, It is quite common to obtain bamboo leaves from our surrounding but most of them were not in use. On purpose of development the way of recycle with common material to dye, bamboo leaves were used to dye on ramie fiber which is valuable for both of apparel and industrial field and investigated their dyeing property. Using extract from bamboo leaves, dyeing property was examined with dyeability, colorimetric property, light fastness and wash fastness under different conditions by extract density, dyeing time, dyeing method and mordants. As results, dyeing was generally colored in yellowish, K/S Value was shown more higher on hemp fiber than ramie. The most optimum dyeing condition was investigated on pre-mordant treatment, dyeing temperature $60^{\circ}C$, dyeing time 30min and extract density 400%. On the treatment with mordant(Al, Fe, Cu), dyebility on both of hemp and ramie fiber were increased by mordant. Especially with Copper(Cu) as mordant, dyebility was highly increased than any other mordants and dyeings showed in deep color. Also on the fastness test which is the most important to natural dyeing, wash-fastness showed good performance with 4-5 grade but light-fastness was above 4 grade on both of hemp and ramie fiber, lower than wash-fastness overall.

The fashion industry saw the emergence of environment-friendly and natural fabric materials recently. The naturalism trend has established sectors in the textile and fashion industry also. Ramie and hemp have long been favored fabric materials in Korea especially for summer. The hand-related mechanical/physical properties of the fabric specimens were analyzed using a fabric objective measurement system, KES(Kawabata Evaluation System). Subjective evaluation was also implemented based on a series of selected adjectives. Studies on natural dyeing methods are important since the establishment of scientific approach is needed in terms of environment and human safety along with the reproduction of traditional natural dyeing methods. In this study, linen, ramie, hemp, and cotton/polyester/linen union fabric specimens were used for the natural dyeing using Rubia akane Nakai with the mordant of gallnut. ${\Delta}E$ values of dyed fabric specimens, mordanted and dyed once using Rubia akane Nakai, increased significantly compared to those of repeatedly dyed fabric specimens without mordanting.
