This study was carried out to investigate the utilization of pruned branch of a peach tree as natural dyeing material. The dyestuff was extracted from pruned branch of a peach tree. we examined the dyeing ability on silk and cotten fabrics. The surface color of silk fabrics differed depending on mordants. E values in treatments of mordants ranged from 11.63 to 30.86 as compared to non-treatment. Dyeing properties of cotten fabrics were improved with a treatment of sulfate of iron as compared with of non-treatment. The values a increased when the slaked lime and sodium hydroxide were used as mordants, while the values b increased when copper sulfate, alum and apple vinegar were used. We investigated the surface colors of silk and cotten fabrics after washing three times. In general, the surface colors of silk and cotten fabrics between the treatments of all mordants and non-treatment were diminished by the washing. We also investigated the surface colors of silk and cotten fabrics when those were washed and treated by the light after soaking those into various pH solutions. The surface colors of silk and cotten fabrics were considerably preserved by the washing, the light and pH concentration. In conclusion, our results suggest that the dyestuffs from pruning branch of a peach tree would be useful as a natural dyeing material using the optimized conditions for silk and cotten dyeing.

Studied on the changes of physical properties according to frequency of washing of sample such as cotton, ramie, wool, cotton knit, T/C. The results are as follows :1. The tensile strength in cotton, wool, and T/C was not changed by 5 times washing but in cotten knit was increased because hang-down phenomenon. 2.The crease resistance of cellulose fiber was decreased by repeated washing. In the case of wool, That was decreased considerably because of decreasing of elasticity and increasing of density caused by shrinking after washing. 3.The abrasion strength of wool was increased with increase in frequency of washing because of thickness caused by shrinking. 4.By repeated washing, the pills was generated in all of the samples and quantity of pills was increased with increase in frequency of washing, the pills was generated in all of the samples and quantity of pills was increased with increased in frequency of washing. Specially, in the case of cotton knit and wool, the pilling was remarkable. 5.The physical properties of dry cleaned wool was superior than that of wet cleaned wool.

This study is to analyze Korean-Chinese women's Costume in Yabian with factors such as reform opening-up, economic growth, change of social values, development of technology, more education opportunities and influence of mass media. It divides the 1990's into two halves. Photos, interview, observation and relevant literature were used for this study. Even though economy grew rapidly, they needed to purchase daily goods other than clothes. In a way that they preferred practicality, it showed somewhat it was still developing. The trend in the first half of the 1990's was characterized : first, Synthetic or artificial fibers and ready-made suits were popular ; second, there still remained the men's style ; third, they wore Tanrikoo(彈力袴), Tisingkoo(體型袴), Jiaotakoo(脚袴) because of its properties of activeness and comfort ; fourth, shoulders looked ore prominent with pads as they were used in Chungsanfoo(中山服) ; fifth, clothes in grey and dark blue was in fashion ; sixth, they wore hand-made knit vests and sweaters and often mountain-climbing gears for its light and warm quality ; seventh, along with opening-up, various materials and colorful clothes were in style, which satisfied women's desire for beauty. They decorated Hanbok(韓服), using sleeves with colors, golden ornaments, flower patterns embroidery, materials of different color in collar and tie and dyes of sleeves and skirts. In the first half of the 1990's when the opening-up was beginning, there were diverse styles and colors in fashion, yet not close to good quality. As the economy grew, the second half of the 1990's was characterized by good palate, individuality, favouritism on foreign goods, rapid change of fashion. For instance, fur coat and woolen fabric were favored. Economic growth led to abundance of cloth, dyes and decorative materials. In addition, people possessed more clothing and it was possible for them to wear both Hanbok and wedding dress in wedding ceremony. People placed their standards on competency and financial ability rather than ideology. Worship disappeared and individuality arose. Therefore, apparel functioned not only as protection but as suits with aesthetic purpose. This resulted in introduction of bold style, imitation of western countries and extension of use of Hanbok. With the help of mass media, transportation, telecommunication, contact with Korean company and civilians, Korean and western cultures, through Korea, were accepted. Change in structure of economic status caused excessive spending and more educational opportunities that enabled people to accept foreign culture quickly. Values moved onto new, beautiful and better characteristics. it was possible to have suits ready-made due to improvement of mass production and cotten, wool, linen, silk became popular owing to technology. New technology, the bases of mass consumption, increased possession of clothing and accelerated change of fashion. In summary, women's Costume in Yanbian were affected by the factors in economy, politics, culture contact as well as change of society and technology.
