Foot and Mouth Disease (FMD) is highly contagious and highly lethal to cloven-hoofed animals. In the winter of 2010, an outbreak of FMD in Korea caused a great deal of economic damage as well as serious mental and physical damage to people who participated in preventive activities. This study provides preliminary data for designing safe and functional protective clothing and gear for individuals who participate in FMD preventive activities. This study was accomplished with multilateral methods such as a documentary survey, field trips, sample analysis of protective clothing and gear, questionnaire studies and focus interviews. As a result, we found that most workers wore low-priced protective clothing that was low in safety functions and rarely wore extra protective gear. Also pointed out was dissatisfaction with: protective clothing and gear, problems related to damage, discomfort, contamination, problems in protective gear related to waterproof functions, protection against harmful substances, discomfort, coldness, and damage. Safe protective clothing could be developed that protects the actual wearers if these results are reflected in the improvement of protective clothing and gear.

Mongolian cashmere sliver, yarn, and fabric were dyed and bleached with a solution of ascorbic acid and iron sulfate at $70^{\circ}C$, and then dyed using natural indigo powder at the dyeing temperature of $25^{\circ}C$ to $90^{\circ}C$ for 15-90 minutes using the IR dyeing machine. K/S values of bleached samples decreased significantly when dyed above $70^{\circ}C$ dyeing temperature for a longer dyeing time. Bleached cashmere fabric showed a greater loss of tensile strength than unbleached cashmere fabric, even when the samples were dyed at $40^{\circ}C$. With a higher dyeing temperature, yarns lost fullness, became thinner, and the pores between the yarns were enlarged. The x-ray diffraction pattern exhibited a prominent increase in crystallinity and the protein assay indicated a loss of protein in the bleached sample dyed at $90^{\circ}C$. Thinning of scales, fractured or raised tip of scales, and roughness on the entire surface of the fiber were also observed. The results indicate that bleaching and high temperature dyeing cause a serious damage to cashmere fibers. In addition, bleaching and high temperature dyeing cause significant fiber damage. Natural indigo dyeing using low temperature dyeing is recommended to produce blue color cashmere.

The conservation of collections in muse-ums is an important aspect for our her-itage. The control of museum environment is a vital factor in the preservation of cool-lections. Inappropriate or fluctuating envi-ronmental conditions can cause irreparable damage to works of arts. In this research we investigated the ac-tual conditions of museum environment for old testiles using questionnaire and mea-sured dye fasing of old textiles on exhibi-tion for 2 months in a university museum the major results are as follows: 1. The control of temperature and rela-tive humidity is a vital factors I the preservation of old textiles in museum generally acceptable temperature and rel-ative humidity standards for old textiles are 18-23$^{\circ}C$ and 50-65% R. H and light level for textiles on exhibition should be limited to 30-50 lux. 2, In university museums the limate control system in exhibition and storage area is in an early stage. Therefore to minimize the deterioration of old textiles the best method of controlling the envi-ronment is to have centralized climate control system in sorage area as well as in display area. 3. Conservator is needed to maintain collections scientifically. Only professional conservator by combining scientific tech-nical and artistic training has the exper-tise needed to maintain the physical in-tegrity of old textiles. In order to solve the inferior environment of museums the staff should recognize the importance of the condition of exhibition and storage. 4. Old textiles are susceptible to damage by light and associated heat. Dyed textiles which have been exhibited under the light without any UV filter were faded notice-ably within two months of exhibition. Light levels for textiles on exhibition should be limited to 30-50 lux. It is de-sirable to use special light source that can absorb UV. and UV filter is also recom-mended to reduce photodegradation of old textiles.

This research is the hair damage as treating a permanent wave before and after that is compared and analyzed the change of physical and mechanical properties. This is the survey of women's hair in 20 years old. On the basis of this we would like to analyze a extend of hair damage. Also, we would to show a basic data for hair damage prevention and hair improvement to keep the beautiful and healthy hair. The conclusion is as follow. : The swelling degree after the treatment was found to be greater than before permanent wave treatment. For the formational characteristics wave, untreated hair certainly had more elastic S curl wave than damaged hair in all the permanent wave treatments, and damaged hair and extremely damaged hair had less elasticity and had saggy S curl wave. The protein permanent and soft permanent wave had thicker, gorgeous, and better elastic wave than the regular permanent wave and direct heating permanent wave in all the hair condition. As the degree of damage on hair got greater, the tensile strength dramatically decreased and as the degree of damage got greater, the elongation was great as well. For treatment method, direct heating permanent wave showed the greatest effect, causing the most damage.

To find out the effect of burn out print finishing for better quality of fabric, examined processing which could make less damages on the fiber because the biggest problem is remained fibers damage after burn out print finishing. Fiber damage examined to the condition of finishing material NaHSO$_4$and H$_2$SO$_4$, 3~10min., 100~13$0^{\circ}C$, glycerin. The fiber damages evaluated the break strength and the surface condition by SEM. Among satin, pile fabric which remained fiber is silk, warp knitted fabric which remained fiber is polyester, the fibers damage level were warp knitted fabric$0^{\circ}C$, glycerin and for 6 minutes by NaHSO$_4$. When carbonized by 20%. 50% and 70% to express textile design, carbonizing rate was not effect on the fiber damage very much. There was almost no damages with glycerine, and almost no damages during 3~6minutes fixation time, 10$0^{\circ}C$ steaming heat fixation by NaHSO$_4$and H$_2$SO$_4$. Without glycerine, there were damage by hydrolysis on polyesters surface and the fiver was broken by fixation time.

The washability, redeposition, fill power, and fabric damage of wet cleaning and dry cleaning solvents were measured to identify the optimal type of washing that would increase washability while maintaining dimensional stability. The soiled fabric is a polyester cotton blend and the types of soil were wine, blood, make-up and sebum with carbon black. Petroleum and silicone solvents were used in dry cleaning. Results from this study are as follows. First, detergency is significantly influenced by the type of washing and type of soil. Wet cleaning is superior to dry cleaning. Wet cleaning shows a strong washing performance against hydrophilic soils, whereas, dry cleaning is stronger against hydrophobic soils. Second, redeposition is significantly affected by the type of washing, fabrics, and soils. Redeposition occurred little on cotton during wet cleaning, but showed a high rate for nylon. However, when the two types of fabric were dry cleaned, redeposition occurred on both types. Third, the fill power of duck-down is very affected by the type of washing. Resilience is the best in wet cleaning; and in dry cleaning, petroleum solvents showed a higher resilience when as compared to silicone solvents. Last, the level of fabric damage to cotton fabrics is highly influenced by the type of washing. Wet cleaning damages cotton fabrics significantly more than dry cleaning. For dry cleaning, petroleum solvents damage these fabrics slightly more than silicone solvents. In conclusion, the type of soil must initially be identified to determine the optimal type of washing. Special caution is required when textiles with particulate soil and nylon are washed. When considering the resilience of duck-down clothing, wet cleaning is more appropriate than dry cleaning. Dry cleaning, especially when using silicone-based solvents, is more suitable than wet cleaning for maintaining the shape of clothing.

This paper has been studied on the method of washing without any damage on wool, namely foam washing method. Effect of washing was obtained with experimental equipment manufactured by way of trial. but some deflects were found that the volume of detergent solution and blow ratio changed with time passes by. This difficulties should be improved by farther studies. The solution mixed with sodium oleate ($0.5\%$) and sodium carbonate ($0.3\%$) was found suitable for detergent solution, and under the conditions of washing temperature at $50\~60^{\circ}C$ and washing time for 5 minutes, the washing effect was obtained good. Desoaping treatment with $Na_2CO_3$ solution after washing might be thought to be necessary, and from the scanning electron micrographs (SEM), no damage on wool and wool sureface washed was, observed. From the results of this study foam washing of wool may be expected to be very effective.

The purpose of this research is to improve sustainable clothes care by comparing household washer's standard course and quick course. Detergency at each course was classified by laundry weight, detergent concentration, and soils. Also, fabric damage from each course was compared. Washing experiments were carried out using two types of washing machines and three types of detergents. Using the standard soiled fabrics of EMPA 108 set, detergency was compared by laundry weight, soil, and detergent concentration. Additionally, fabric damage was evaluated using the mechanical action of MA-40. The results of the research were as follows. First, a standard course, having more working time exhibited better detergency than a quick course. However, the detergency deviation under 6kg laundry weight was as low as 9.0%. Second, detergency by the type of soil was more effective in standard course than in a quick course, but hydrophilic protein soils had a small detergency deviation at 7.6%. Moreover, hydrophobic oil, complex, and particulate soils had a higher deviation at 19.7% Third, fabric damage was in proportion to operating time. Fourth, a quick course showed approximately 80% detergency regardless of the type of detergent. in the case of using 50% of the recommended allowance by the detergent manufacturer. In conclusion, reducing the operating washing time and detergent concentration is in accordance with increasing sustainability, in the case of washing with lightly soiled fabrics under 6kg of laundry weight.
