The effect of direct dyes in the dyed fabrics on the ultraviolet ray shielding efficiency has been studies in relation to the chemical structure and properties of direct dyes. Nine kinds of direct dyes different in chemical structure (five blue dyes and four yellow dyes) were examined together with five red dyes previously reported. The effect of light absorption properties (i.e., color and luminous ref lectance) in the visible
wavelength on UV-ray shielding properties has been discussed. The results are as follows.
1) Direct blue dyes, especially Blue 71, have relatively high molar absorption coefficient at the regions of UV-B. Direct yellow dyes, especially Yellow 50, have relatively high molar absorption coefficient at UV-A.
2) Fabrics dyed with yellow dyes have exhibited high luminous reflection and high UV-ray shielding effect even for light colors in spite of high exhaustion. It might be caused by high light absorption in UV-A region ranging over the visible short wavelength.
3) The fabrics dyed with red or blue color has shown an effective UV-ray shielding for deep shade color. Shielding properties of red color fabrics are better than those of blue color fabrics.

This study has successfully used regression method to establish a transformation model between fabric properties and subjective fabric textures and has evaluated fabric texture objectively. The three types of regression models established, including enter method, stepwise selection method and factor method, have high R-square and low residual, indicating that the models have high ability of fitting. Besides, fabric textural evaluation becomes simpler and more convenient, objective and effective when stepwise selection method can be applied with merely four fabric-properties are required to establish evaluation model for fabric textures. Factor method, although, does not have prediction ability as good as enter method, it nevertheless provides the key information, including fabric thickness and color, the most important factors that may affect visual textures.

The purpose of this study is to clarify the dressing image and color effect of business suits. The colors of suits, shirts and neckties were changed using CG and used as samples. These samples were evaluated at five levels by SD method. Total 120 persons including young men, middle-age men, single women and married women were investigated. Evaluated values were analyzed using factor analysis and quantification theory I.
The results are as follows:
1) The dressing image of business suits are composed of two factors: “harmony and social desirability”and“conspicuousness”.
2) Regardless of wearers' age, navy blue and gray business suits increase“harmony and social desirability”.
3) Harmony and social desirability will increase if conspicuousness is set at from neutral to a little high for models in their twenties, and set at low for models in their fifties.
4) The effect of harmony and social desirability will be increased if models in their twenties wear shirt and necktie with identical, similar and contrastive colors, and if models in their fifties wear shirt and necktie with identical and similar colors.
