The cleaning efficiency of papermaking felt which is contaminated with fiber fines and various micro-materials was investigated and compared between the application of enzyme and commercial detergent. It was found that the cleaning efficiency by the treatment of acidic-based detergent was more efficient than that of alkaline-based one in the conventional commercial detergent. it was also observed that the treatment design of first acidic-based detergent treatment to second alkaline-based detergent procedure was better in the cleaning efficiency, compared to alkaline based-to-acidic based one. The cleaning property of felt with enzyme was resulted in good cleaning efficiency, without any addition of surfactant. Especially, the enzyme treatment under alkaline condition (pH 10) showed a better cleaning result than that under acidic condition(pH 5). The addition of nonionic surfactant to the enzyme increased the cleaning efficiency of felt and decreased the cationic demand of wastewater. These results showed more favour than the application of conventional commercial detergent.

This study was conducted to determine cleaning effects of environmental-friendly washing detergent on milking installation in dairy farms. Milking machine, cooling machine and milking liner were washed by alkaline detergent and acid detergent for first three weeks and alkaline detergent and environmental~friendly detergent for next three weeks and the results get through microorganism and physico-chemistry analysis at the five district dairy farms different from environment. E-coli, coliform, fecal coliform, staphylococcus aureus, fecal streptococcus, prsudomonas aeruginosa and yersinia were not found in all of the dairy farms, and total colony counts were no difference compared with chemical detergent. The water for washing exceeded the determining acceptable level of nitrate nitrogen in the Anseong, Onyang and Cheonan and the remaining substance of washed water was also high levels. The cause of the result was that the level of nitrate nitrogen of water is basically high. Therefore, this study indicated that washing effect is no differences between environmental-friendly detergent and chemical detergent by washing for milking machine and cooling machine. Above all, producing high quality milk is to manage the water quality as well as using detergent.

To investigate detergency of various woven fabrics in relation to the detergents and washing temperature. cotton, polyester/cotton (p/c), nylon, acetate, and polyester were soiled in aqueous artificial ($carbon-CCl_4$) soil. Each fabric was washed with soap, alkaline and neutral synthetic detergents at $30^{\circ}C$, $40^{\circ}C$ and $60^{\circ}C$ respectively. The results obtained may be summerized as follows; 1. In soap, ascension of temperature had the most important effect upon washing efficiency and the higher the temperature was, the higher the washing efficiency was showed in all fabrics. And in case of alkaline synthetic detergent, nylon and p/c fabrics were much more difficult to clean at higher temperature and also acetate and polyester had the best efficiency at $40^{\circ}C$. Detergency of neutral detergent was good but the effect of temperature in neutral detergent was less than in soap. 2. Washing efficiency of cotton was less than that of others. 3. The higher the temperature was, the higher the washing efficiency of cotton in all detergents, and the best was in soap. In p/c, detergency of neutral detergent was good but effect of ascension of temperature was lower than in soap. In nylon, washing efficiencies of alkaline synthetic detergent and neutral detergent were excellent at 30°C but detergency of soap at $60^{\circ}C$ was best. In case of acetate, detergency of all detergents was about the same at $30^{\circ}C$ but that of soap at $60^{\circ}C$ was best. In polyester at $30^{\circ}C$, efficiency of neutral detergent was excellent but that of soap was more excellent at higher temperature and the best detergency of alkaline synthetic detergent showed at $40^{\circ}C$. In general. the higher the temperature is, the higher the washing efficiency of soap is. But when synthetic fibers of nylon and polyester are washed with synthetic detergents, washing at lower temperature is advisable.

The purpose of this study is to find out the better washing condition, especially on detergent contents to satisfy the consumer's concern on fabric hand using Drum Type Washer. The hand and preference of washed fabrics by various detergent contents were analyzed through subjective evaluation using questionnaire method in dry and wet state. Wine rank's semantic differential scale questions were developed with 27 kinds of adjective pairs and seven rank's scale questions were to evaluate preference of washed fabrics oil holistic touch, washing and rinsing effect and purchase intention of detergent. Group of trained panelists and untrained women panelists of $30{\sim}40$ years old were participated. The factors affecting consumer's taste for the washed fabrics were analyzed by SPSS 12.0. Smoothness showed relatively higher correlation with preference of washed fabrics on holistic touch, washing and rinsing effect and purchase intention of detergent. There were significant differences in preference of washed fabrics on holistic touch, washing and rinsing effect and purchase intention of detergent by detergent contents when tested in wet state. Fabrics washed with detergents of non-zeolite were appeared to be the preferred ones.

This paper discussed the influence of addition of aqueous additives such as various beverage and detergent on the properties of concrete during placement by workmen's mistake. Slump and air content were not highly affected by the addition of aqueous additives, while addition of detergent led to an remarkable increase in air content due to interfacial activated ingredient in detergent. For setting time, lactic-acid fermented milk exhibited a longest setting delay and in order of coffee and soda. Concrete containing setting retarding beverage had higher compressive strength than control concrete at 7 and 28days. Concrete containing detergent exhibited strength loss due to the presence of larger amount of air content.

The use of both an Alpha Hydroxy Acid, Citric Acid, and a Skin Moisturizer, Glycereth-26, formulated into a hand dishwashing detergent have been shown to be synergistic in their effects on certain skin health parameters. Each ingredient was evaluated alone and together in a hand dishwashing detergent via a 9-week use test. Panelists washed dishes using the sponge method commonly used in Asian markets and a 1:7 dilution of the concentrated dish detergent. Panelist's hands were evaluated initially and at 3-week intervals for nine weeks. After nine weeks panelist's hands showed significant improvements in Moisture Absorption and Transepidermal Water Loss (TEWL). A synergistic effect on TEWL was found between the AHA and the Moisturizer. These effects, showing an improvement in the condition of the panelist's skin are impressive, particularly since they were observed from a dishwashing product that is highly diluted and at near neutral pH during the washing process.

The exposure to house dust mites is closely connected with allergic diseases such as atopic dermatitis, allergic rhinitis and asthma. Control of house dust mite populations has been principally achieved by using chemical insecticides. But the risk to human health would be a potential problem. Moreover, house dust mite remain as allergens even after death. Therefore, repelling the house dust mites is more effective method than killing them. The use of plant-derived repellents has been considered as a promising alternative to chemical repellents. Eucalyptus oils are regarded as safe compounds, there have been attempts to commercialize and market the insecticides/repellent products containing Eucalyptus oil as such or based upon them. For that reason, we experimented repellent activity against these mites using laundry detergent with Eucalyptus oil in this experiment. House dust mites (Dermatophagoides farinae and Dermatophagoides pteronyssinus) were exposed at different concentrations (4, 8, 16, $32{\mu}L/mL$) in fabric treated laundry detergent with Eucalyptus oil for 24 hours. The repellent effects (%) of laundry detergent with Eucalyptus oil exposed at 4, 8, 16, and $32{\mu}L/mL$ were 48.16%, 74.62%, 52.67%, and 44.47%, respectively. These results suggest that laundry detergent with Eucalyptus oil have potential effect to repel the house dust mites.

This study comparatively analyzed the changes in the dimensional stability and the mechanical properties of stretch knit fabrics associated with washings conditions in order to determine the most appropriate washing method. Polyester and spandex knit fabrics were washed 25 cycles with nine washing condition profiles that controled detergent, hardness. temperature and RPM. The knit fabrics with repeated washings were evaluated by dimensional stability and measured by the KES-FB system. Polyester and spandex fibers have good chemical resistance. However, the changes in the dimensional stability and the mechanical properties were observed in washed knit fabrics. After repeated washings, the knit fabrics washed in an alkali or neutral detergent had good dimensional stability compared with the knit fabric washed in functional detergent. The washed knit fabrics were extended, stiff, rough, and had a smaller volume. The changes were the result of the rearrange of polyester fibers which twisted around spandex core and chemical interactions involving the detergent and the physical and mechanical forces of washing. Especially, using an alkali detergent resulted in increased stiffness and roughness of the knit fabric. In conclusion, the washing in water with low hardness and a neutral detergent can minimize the changes in dimensional stability and mechanical properties of polyester and spandex knit fabric.
