    We analyzed the influence of gravity on removal of solid particles (polyethylene, polystyrene latex and glass particles) adhered to the under-surface of glass plates in the washing device previously reported.
    The removal behavior of particles in the fluid was observed by a combination system of VTR and a personal computer, and it was defined into three types as follows; A1 type removal (particles moved along the substrate parallel to the direction of the fluid and then disappeared from the monitor), A2 type removal (particles redeposited after having moved from adhesive position), and B type removal (the others) .
    These particle behavior was shown to be influenced by gravity: Polystyrene latex, glass and polyethylene particles have three removal types A1+A2+B, two removal types A1+B, and two removal types A1+A2, respectively.

  • —On Sleeve Cap and Armhole Curves—

    In this study, the armhole and sleeve cap curves are obtained by using two mathematical equations, and discussions are attempted to clear the structure of these curves.
    The two mathematical equations are as follows:
    1) Super elliptical equation,
    (X/A) p+ (Y/B) p=1, (0<X<A, 0<Y<B, 1≤p<∞……………… (1)
    2) N-th power equation,
    Y=B· (X/A) N, (0<X<A, 0<Y<B, 1≤N<∞) ……………… (2)
    For drawing paper patterns, a computer graphic method is quite useful.
    For example, a rectangular with two sides, A and B, is drawn easily and a diagonal curve which constructs a shape of the pattern is also drawn by using the above two equations. A and B are size or measuring factors and parameters P and N are structural factors.
    In these patterns, curve length or seam length of the pattern drawn is calculated by a computer. On the other hand, the sleeve cap or armhole length measured can determine parameter P and N of the curves as shown in Figs.6 and 12.

    Experiments were carried out in order to make clear the influence of the sunlight, under which underwear are exposed in the drying process, on yellowing of the garments during the stowing.
    For samples, white cloths applied with squalene, instead of used white underwear, were examined.
    The results obtained are as follows:
    The degree of yellowing of the cloths dried in the sun is larger than that of the cloths dried in the shade. While it is noteworthy that the b value of the cloths dried both in the sun and in the shade in a room were nearly equal and their POV shows a great difference immediately after the end of the drying of sample cloths.
    It seems that the facts mentioned above suggest the interpretations on the processes of yellowing of clothing dried both in the sun and in the shade in a room.
