Cuprammonium rayon fabrics were dyed with direct dyes by means of a microwave heating. The fabrics were dyed by the following two procedures: (A) The fabrics were dipped in an aqueous solution of the dye for 1 minute at 10°C or 10 second at 70°C. After being squeezed lightly (pick up 170%), the fabrics were heated by a microwave (500W) for 1 minute. If necessary this procedure was repeated 2-5 times. (B) The fabrics were printed with color pastes at 10°C. Without being dried, the printed fabrics were heated by the combination of microwave and steam.
The fastnesses of the dyeings dyed by (A), washing, rubbing and light fastnesses, were not enough. On the other hand, the fastnesses of the dyeings dyed by (B) were good enough and similar to those of the standard dyeings. The results of the dyeing fastnesses were explained in terms of the rate of vaporization of water in the fabrics and the rate of diffusion of the dyes in to the fiber during the heating process.

In the costume design, optical illusions are created by the use of parting lines. Fundamental constructions to consist of parting lines of horizontal, vertical and angle were put in practice in one-piece dress.
The test samples, colorslides made by the use of a color simulator, have been assessed by the semantic differential method using ten adjectives suitable to express the optical illusion. Parting line samples have been discussed, in terms of the human emotion, by the Quantification Scaling Theory (QST), Type 3. The images of one-piece dresses having parting lines have been determined by the factor analysis. The analysis of variance were made by the QST, Type 1.
The results have shown thah the visual impression of dresses having parting lines is composed of thr-ee factors; tallness in stature and slimness, sharpness and simpleness. These factors have been affected horizontal lines on the waistline, color of dress, direction and largeness of angle.

If the human skin is observed through a polyester or silk plainweave habutai or crepe de chine, the variation may be observed in the chroma of the color of the human skin. A goniophotometric colorimeter was used to measure the variation of the skin color which might be affected by the incidence and the receiving angle of fabrics. The following results were observed:
(1) The distance between a fabric and the skin has little effect on the color variation.
(2) From a specular reflected direction at a raceiving angle of 45°, it is difficult to perceive the skin color. With the receiving angle between 0° to 30° the color of the fabric and skin color form a twocolor mixture resulting in the easy perception of the human skin color.
(3) The skin color is less perceptible through a crep de chine, compared with a plainweave habutai, due to rough fabric surface.
(4) The skin color is less perceptible through a silk plainweave habutai, compared with a polyester one, due to the better light diffusion quality of the silk fiber.
(5) The human eyes can perceive the human skin color at a wider receiving angle than a goniophotometer can do.
