A study on the washing efficiency with various washing conditions - Focus on detergent concentration and temperature -

Nowdays, costumer's washing behavior were often times for remove to light-duty dirt. The purpose of this study is to provide the most effective washing conditions of detergent concentration and temperature conditions for help save energy and water resources required to the washing process. Washing conditions were as follows: 2 kinds of detergents and 4 types of artificially soiled fabrics were used. Detergent concentration was 0%, -10%, and -20% below the recommended conc. of manufacturer's standard. Temperature of bath was $20^{\circ}C$ and $40^{\circ}C$. The results of this study were as follows: First, washing performances of all kind of artificially soiled fabric improved as the temperature of bath at $40^{\circ}C$. Second, the test was conducted under the condition of decreasing respectively -10% and -20% below of the recommended concentration of manufacturer's standard detergent. The average of washing efficiency was not considerably affected by the reduction of 10% below of manufacturer's standard. Third, in case of the water temperature were $20^{\circ}C$, polyester/cotton blended fiber were higher degree of washing efficiency than cotton fiber.
