    The colorfastness to light and perspiration for four vinylsulfonyl (VS) reactive dyes, C.I. Reactive Red 22, Blue 19, Black 5 and a copper-complex azo dye, on cotton fabrics was examined by seven testing methods. The pH effects on the fading by the compound action of light and sweat were also studied by these testing methods. JIS L 0888 method using with acid and alkaline perspiration could not estimate the difference in their fastness. The ATTS method with alkaline perspiration and the lactate method, followed by the Mizuno method, can estimate strictly their fastness. The differences between the fading by alkaline and acid perspiration were made by the initial period of exposure during the test fabrics were wet. By increasing the concentration of substrate in the artificial perspiration, for instance, by the lactate method, the high fastness of light and perspiration for dyes on cotton fabrics may be estimated.

    To study a removal mechanism of solid particles, polyethylene and glass particles adhered respectively to cellulose, acetate and polyester films were removed in the washing device, and FH1/2, the force necessary to detach the soils, was estimated. The particle behavior was recorded on a video tape, and analyzed by a VTR system and a personal computer. The results were compared with the previous results using polystyrene latex particles.
    The following insights were obtained:
    1) FH1/2 existed only glass particles in the order of: cellulose<glass<acetate<polyester.
    2) Glass particles had two types of removal behaviors, A and B types. But polyethylene particles had only B type. The ratio of A type removal affected on the hydrophilic property of substrates.
    3) The glass particles of A type removal had two types of removal behavior, A1 and A2 types. The rate of A1 type removal was higher than that of the A2 type removal, irrespectively of flow speed. The moving speed of A1 type particles was faster than that of A2 type particles, that have already been reported as polystyrene particles.
    4) The distance between particles on the hydrophilic substrate was estimated to be longer than that on the hydrophobic substrate. With polystyrene latex and glass particles, the removal percentage increased with the increase in the distance.
