The purpose of this study is to investigate how the striped patterns effect on the apparent configuration of curtains. The results are summarized as follows:
1) A significant difference was visually found in the curtain configuration with a different types of striped patterns.
2) Vertical stripes had an effect to make a curtain look more amount of pleats.
3) Horizontal stripes had an effect to make a curtain look more regular configuration.
4) Vertical stripes on curtains gave a vertical impression, and horizontal stripes a horizontal impression.
5) Striped patterns are more influential on the image of a curtain configuration than a making-up condition.
6) The image of a curtain configuration is represented by three factors, such as“aesthetic”, “formal”and“voluminous”.

In washing cloths with commercial detergents, enzymes work inevitably under the influence of the detergent components. Our previous reports have shown that the activity of an alkaline protease in the hydrolysis of dissolved protein, gelatin, is enhanced or suppressed under the presence of certain components of the detergents. Our last report has also shown that this is true in the hydrolysis of solid protein and the following dissolution.
Based on these studies, the present study is performed to reveal the synergistic effects of the protease and some of the detergent components, namely surfactants and oxidizing agents, on the detergency of artificially stained cloths. Two kinds of stained cotton cloths were used: one was supplied by Sentaku Kagaku Kyoukai (Institute of Washing Science, Japan) and another one was stained with coffee + milk. After washing the cloths, in a Terg-O-tometer and in a shaken elrenmeyer flask, the variation of the reflectance and the degree of the removal of milk protein attached, were measured. It was found that the correlation between the detergency estimated from a reflectance and the protein removal for the cloth soiled with coffee + milk, was very high as expected. Further, the detergencies of the two kinds of stained cloths were estimated for the washing solution base (B) containing sodium carbonate, sodium sulfate and carboxy methyl cellulose; B + surfactants (S) ; B+S+an alkali protease (E) ; B+S+E+Oxidizing agent (O) ; and B+S+E+O+activator (A) under two different (conditions for) washing time and temperature. It was found that in such model washing systems, the detergency by the protease is also enhanced or assisted by the presence of some nonionic surfactants and oxidizing agents.
