Description

<p>  The application of fine bubble water to rinsing in the laundry process was attempted to construct a favorable detergency system. Polyester spun and filament fabrics soiled with carbon black, red clay or stearic acid were washed together with original polyester fabrics in an aqueous sodium dodecyl sulfate solution with and without mechanical action. The fabrics were rinsed with pure water with and without fine bubbles after washing. The detergency, removal efficiency and soil redeposition were evaluated using the surface reflectance method. All artificially soiled fabrics had a higher detergency when rinsed by fine bubble water than they did when rinsed by pure water, especially after washing without mechanical action. Rinsing with fine bubble water was found to decrease the amount of sodium dodecyl sulfate remaining on the fabric.</p>
