Cotton woven fabrics were treated with ultrasonic and ultraviolet irradiation to prepare a fabric modified by two types of titanium dioxide (TiO₂). The specimens modified by TiO₂ were investigated on the wash durability and aesthetic properties. The specimen fabrics prepared by irradiation of ultrasonic and ultraviolet (UV) light increased supporting TiO₂ compared to that modified only by ultrasonic irradiation. The prepared cotton fabrics, i.e., TiO₂ stably-maintained on the cotton fabric, had a resistance to washing. On the measure of aesthetic properties, untreated cotton fabrics changed their properties to the rougher surface, lager “SHARI'' and smaller “FUKURAMI''. However, cotton fabrics modified by TiO₂ reduced deterioration of aesthetic properties by the effect of UV light. Cotton fabrics modified by anatase TiO₂-SiO₂ complex show the less effects on damage of fabrics.
In the case that anatase TiO₂ fabrics were applied to the degradation system of Orange II dye, the degradation rate of Orange II was 100% under UV light irradiation for 24 hours.

The apparel market has begun to supply consumers the socks which bring about not only comfortable wearing feelings but also functional effects such as to restrain a swelling of feet. However, there are many products in disregard for health considerations as aimed solely at the swelling of feet. In the present study, we propose a new design of comfortable and warm support socks, so as to prevent the swelling of feet and to keep tiptoes warm without constricting of the circulation of the blood. Subjects participated were 8 healthy female (21.6±1.1 years old). The measurements were taken in the latter half for a high temperature phase of their menstrual periods. We measured the volume of foot and the skin temperature of the toe, when the ankle and the arch were both or separately constricted. Values obtained were compared with those before and after 4 hours upright sitting. Four constrictive conditions were shown as follows: Condition ① perfect-fitting feelings at the ankle in which the clothing pressure was 12.4±4hPa(mean ± SD), Condition ② tight-fitting feelings at the ankle (28.4±5.2hPa), Condition ③ tight-fitting feelings at the arch (34.7±6.7hPa), and Condition ④ tight-fitting feelings at the ankle and the arch (29.6±3.8hPa). The volume of distal part to the ankle (Region A) decreased in two conditions (Condition ① and ④) in comparison with control experiment, and the volume of ankle (Region B) decreased significantly in Condition ④. On the other hand, the skin temperature of the toe decreased significantly in Condition ①, ②, and ④, as compared with control before compression. In Condition ④, the volume decreased in Region B, but increased in Region A, and the skin temperature of the toe decreased significantly. It is concluded we should not constrict the ankle till tight-fitting feeling. That is, to keep the toe warm and to reduce the swelling in Region A, we must carefully determine the constrictive degrees such as in the perfect-fitting feeling at the ankle and in the tight-fitting feeling at the arch. At this point, the clothing pressures are calculated 15.2hPa at the ankle and 34.7±7.1hPa at the arch.
