Hair bleaching is a treatment process in which the melanic pigment is oxidized by hydrogen peroxide. With the increase of the number of treatments, $1{\sim}10$ levels of various colors develop, the hair luster diminishes, and the appearance becomes very rough. In this study, by changing the number of hair bleaching and bleaching conditions, the changes in the degree of hair damage and its process were observed through the use of scanning electron microscopy. The color changes were also compared through the use of spectrophotometer. In order to study the physical changes of the bleached hairs and to search for the optimum conditions to keep the hair damages minimum during bleaching, tensile properties were measured and reviewed. By increasing the number of hair bleaching and by the severe conditions, the scales became eroded and the protection layers were decreased, and the oxidation reached the inner sectors resulting in rough surface and fibrillation. The surface of the hairs became bright yellowish and transparent by the bleaching of melanic pigments or by the destruction of pigments. With the increase of bleaching degree, in terms of physical changes, the breaking strength decreased while the elongation increased a little.

This survey provides research into developing knee braces to protect the knee against damage, reduce knee pain, and strengthen the knee. A total of 235 surveys were conducted from December 2019 to January 2020. The subjects were adults in their 20s and over who lived in the Seoul metropolitan area and had experience of using knee braces. In terms of age differences, subjects over 60 years of age purchased knee braces mostly to secure a reduction of pain (ROP), whereas subjects in their 20s and 30s purchased knee braces for physical shock protection (PSP). Subjects in their 40s and 50s purchased knee braces for improvement of muscle movement (IMM). There was no significant difference in shape, material, and locking method based on the reason for wearing the knee brace. These results show that it is conceivable and maybe preferable to produce different knee braces-with a variety of shapes, materials, and locking materials-according to the reason behind wearing a knee brace. Knee braces are worn currently without any differentiation despite the findings of this study. In particular, we argue the need for functional and differentiated development of knee braces specifically for PSP, ROP, and IMM.

Cotton fabric was treated with acrylonitrile in t-butyl alcohol and then aminized by reduction of the resultant cyanoethyl cellulose with LiAIH4, under various temperatures and times. Aminized cotton fabric toras dyed with acid and reactive dye. Dyeability as to temperatures, pH, and color fastness were compared to the amiRe group content of treated cotton fabrics. The results of this study were as follow: 1. D.S of cyanoethyl cellulose has been increased by increasing treating temperatures and times. Maximum D.S of cyanoethyl cellulose was 1.45. By SEM and the tensile strength, the damage of the treated cotton was not observed. 2. Since aminized cotton has greater affinity on acid dye than untreated cotton, dyeability increased with the increase of amino group content, and the lower pH, $60^{\circ}C$. 3. Since amino group in aminized cotton changes surface charge of cotton, dyeability for reactive dye increased by increasing the amino group content. Optimum dyeability was obtained at pH 5-7, $40^{\circ}C$. And dyeability of the amine treated cotton increased with the NaCl conc. 4. Color fastness to washing & light of the amine treated cotton was very low except for the wash fastness of the reactive dye.

The purpose of this study is to establish the conservation methods of embroidered textiles and textile works. The conservation of remained textiles is consisting of examination, cleaning, support and consolidation, restoration, and storage and display process. It aims to prevent the damage on textile remains for long time display and storage and to prolong their aesthetics and functionality. The embroidered textiles and textiles works, which are remained by handed down or excavated or included in the Buddhist are embossed with colorful threads on the fabrics: the stitches include embroideries on clothing, bed clothes, wrapping clothes, utensil pouches, panels and Buddhist goods; textile works include hats, ornaments, shoes, attachments of clothes etc. These are composed of mainly fabrics, precious metals, leathers and precious stones, etc., and are fabricated by several techniques such as braiding, twining, sewing as well as weaving. Metal threads were also used to add a decorative effect on these goods. In order to conserve and preserve the remained goods, a special care must be taken on the metal threads, which are the most fragile material among the constituents. Hence, characteristics of metal threads and its cleaning methods, general conservation techniques of a rank badge, which is brocaded and partly attached to Cheogori and Samo(men's hat) from the excavated old tombs are introduced here.

This study explores if consumer perceptions about genuine luxury fashion merchandise are affected by the presence of counterfeits. A total of 504 consumers participated in an online survey. First, respondents were asked to indicate whether or not they agreed that counterfeits negatively affect genuine luxury fashion brands and to provide reasons for their responses. Approximately 57% replied that counterfeit goods negatively affect the image of genuine luxury fashion brand goods. The main reason mentioned was that counterfeit products damage the producer/copyright holder of genuine products, as well as the national economy; they believed that it damaged the genuine luxury brands' image due to the luxury goods becoming less rare; however, 43% of respondents stated that counterfeits did not negatively affect genuine luxury fashion brands. Thus, counterfeit availability reflects that a brand is renowned and popular in a market where consumers can recognize genuine luxury fashion products from counterfeits. Second, the respondents were asked about specific luxury fashion brands and indicated that seeing counterfeits did not negatively affect genuine luxury fashion brands' value, brand reputation or satisfaction of ownership. The majority of respondents disagreed that the availability of counterfeits negatively affects the value, reputation and satisfaction of owning original luxury brands.

This study was aimed to isolation and identification of attached bacteria on the clothes excavated from Deajeon area dating on the 16th century. From the observation with colony shape, 17 bacterial strains were isolated, and then 7 bacterial strains were identified with morphological and biochemical characteristics. Streptococcus sp., Alcaligenes faecalis, Gemella sp., Acinetobacter sp., Pseudomonas vesicularis, Aeromonas sain. salmonicida, Moraxella spp. In observation of the bacterial strains by the sort of textile, more bacterial strains were found in silk, cotton, and cotton batt than in ramie and hemp. It is suggest that hemp has antibacterial characteristics due to the presence of lignin. In the comparison washed samples with unwashed ones, there were more kinds of bacterial strains in washed samples. In the cellulase activity tests, all isolated bacteria had low level cellulase activity.

The indigo-dyed blue denim garments are favored not only by young people but also by almost everyone of life, In the early years they were casually worn on most occasions but became universal recently. Such denim garments are treated with various process to give it optimal softness and color contrast of blue and white. The processess can generate photoyellowing and thus the yellowing may damage their appearance and quality. So this study is to find the solutions to reduce the photoyellowing problem. For this prupose sample denim were treated with cellulase fluorescent brightener UV absorbent etc. The results were as follows; The yellowing would be more accelerated by fluorescent brightening. Since the yellowing was reduced by 90% In particular the application of the UV absorbent before using of the fluorescent brightener was most effective. The optimal concentration was 0.5% (o.w.f) and the benzophenone compounds were found most effective for the indigo denim. And reduction effect of yellowing by UV absorbent was lowered with repeated laundering but metal compound treatment on fabric made a removal of UV absorbent by laundering prevented.

This paper describes the processes conducted in the analysis and conservation of suit worn by Yu Rim (1898-1961). The suit consists of a jacket and pants and is a typical Mao-style suit for independence activists; it is notable in that it was made of domestic wool. Inside the jacket, there is a machine embroidery of the name "Danju," a label of synthetic resin which reads "Daegu citizen's tailor's shop," and buttons engraved with "PUSAN SIN-HUNG." According to our textile analysis, the outer layer is composed of worsted wool while the lining is made from acetate. Damage to the garment from malodor and insects has been repaired, and the suit has been restored to its original shape by a conservation treatment that has reinforced the textiles. This conservation case can provide valuable research data on the preservation of modern and contemporary clothing. In addition, this study also attempts to estimate the date of suit worn by Yu Rim's production by comparing it with woolen suits produced around the same time and examining the clues associated with the relics. This is significant since it enhances the value of the cultural assets and provides detailed information on the historical transformation of domestic suits.
