In order to save resources and energy in textile washing, ultrasound was applied as a mechanical action for soil removal. Plain-woven polyester, cotton and polyester/cotton (65/35) fabrics were soiled with oleic acid, carbon black or oleic acid/carbon black mixture as a model soil. The artificially soiled fabrics were washed in an aqueous anionic surfactant solution with applying 38 kHz ultrasound. The detergency determined by the surface reflectance method rapidly increased with time and attained almost constant within a few minutes. The detergency after 1 min washing was found to increase with increasing electric power consumption of ultrasound. The washing tests were repeated ten times in the same wash bath to save water and detergent and the obtained detergency did not change significantly. The detergency of oleic acid and oleic acid/carbon black mixture after washing with 420W ultrasound for 1 min was comparable to that with Wascator, a horizontal axis drum type washer. Furthermore, the mechanical action values obtained for ultrasonic washing were much smaller than those for Wascator, indicating that the fabric damage can be prevented by applying ultrasound to textile washing.

This study aims to obtain some guidelines for designing school bags that will reduce the body load. We analyzed school bag factors that affect shoulder strap pressure in terms of the shape of strap, its cramp and waist belt. Waist belts are not used usually in school bag design. However we thought that it would be useful for reducing the body load. Seven pupils were used as test subjects. The strap pressure of the shoulder part of the curved strap was lower than that of the straight strap. But the maximum pressure and standard deviation of the curved strap were larger than that of the straight strap. The curved strap was dependent on subject's body size. An important factor was the shape of the curve. The strap pressure of the pivoting cramp was lower than that of the fixed one. Therefore, it was shown that the pivoting cramp reduced the body load. The strap pressure of school bag with waist belt tended to reduce the body load. But the effectiveness of some waist belts were dependent on the subject's height. In particular, the waist belt with the soft and wide pad didn't fit some tall subjects. It was suggested that the change in the height of one's waist due to growth was the most important factor.
