    In the foam dyeing of nylon 6 muslin fabric with disperse dye (C. I. Disperse Violet 1), the influence of air flow rate on the following foam properties were investigated: the foam flow rate, dye concentration in the foam film, the blow ratio, diameter of the bubble, and the number of the moving bubbles.
    The dye concentration in the foam film decreased by the air flaw rate increase; the dye adsorption at equilibrium was not depressed. In addition, the increase of the air flow rate raised the foam flow rate and the number of the bubbles and/or Plateau borders, that transported on the substrate. These bring about the liquid flow around the substrate, and depressed the thickness of diffusional boundary layer.
    In the foam dyeing, therefore, the increase of the air flow rate brings about the good dye ability in the terms of dyeing rate without affecting the equilibrium state.

    The types, wearing combinations and thermal insulation of clothes of women's college students in summer were investigated in comparison between in 1968 and in 1986.
    1. The number and weight of underwears decreased, and the area of skin coverage tended to decrease. Outer garments tended to have increased weight and the materials tended to become diversified. This seemed to supplement the role of underwears. The area of skin coverage by outer garments increased. This seemed to reflect the increased number of air-conditioned facilities.
    2. The thermal insulation of garments in June and July increased for adaptation to indoor lower temperature due to the popularization of air-conditioning. In August, an environmental thermal condition undergoes a little change, compared with June and July. The resistance of students to hot weather was found to have been diminished, in spite of the reduced thermal insulation of clothes.
