地球環境が温暖化し、人々の生活にも大きな影響を及ぼしている。暑熱気候を少しでも快適に過ごすためには、暑い環境や寒い環境での各種繊維素材布の熱伝導特性を知り対策を図る必要がある。様々な布素材の熱伝導率(山田1997)、絹布はどうして涼しいのか(山田・成瀬2002)について知見を得ることができた。<br>ここでは、環境の温度と湿度を変えて熱伝導率を計測し、布の熱伝導率は、空気、水分、繊維の各体積率とその熱伝導率の和によって求められることが判った。また、布の熱伝導率のうち繊維(異断面・異方向に並んでいる)の熱伝導率の寄与が最も大きいこと、得られた繊維固有の熱伝導率は、温度の影響よりも繊維体積率の影響が大きいことが判った。

2才から91才にいたる81人の健康男子の毛髪を5才ごとに区切り, 各群5人を選び, 1人5本の試料について, 洗浄後, 蒸留水で十分湿潤し, テンシロンIII型万能引張り試験器で切断荷重, 切断伸長率, 切断仕事量および立ち上りのヤング率を測定した. 毛髪の直径は60~140μの間に分布し, 15才前後をピークとして, 以後加齢とともに漸減の傾向を示し, 二次曲線, または, 15才ごろまでは上昇以後下降する2本の直線の合成として表現される. 年齢と切断荷重, 年齢と切断仕事量の推移もほぼ同様である. これに反し, ヤング率は, 20才ごろまでは減少し, 以後加齢とともに徐々に上昇する二次曲線への回帰が統計的に有意である. 加齢の指標の一つとして, 毛髪の物理的性状の研究は有用である.

Up to the present time, there have not been many studies carried out to determine an effective method for systematical conditional setting for polka-dot patterns, because most previous studies have used commercial printed polka-dot patterns. Therefore, we prepared thirty samples with different patterns wherein two kinds of patterns (i.e., an oblong and a square) each with polka-dot diameters of 1.6, 1.4 and 0.8 cm were respectively combined with five different colors by means of CG (computer graphics). In addition, in these samples, area ratios of the polka-dots to the background area were consistently maintained at 1 : 7 for the rectangular pattern and at 1 : 5.8 for the square pattern.Characteristic values of these samples were obtained by means of optical measurements and a sensory evaluation to try to determine those factors, which controlled images expressed by the polka-dot patterns set in different conditions. The following results were objectively proved.1. From the results of the SD method, a more significant distinction was found in the evaluation of color samples of different color values for each polka-dot size than in that of different dot sizes on each color sample.2. From the results of the t-test, a more significant distinction was found in the evaluation of the two design patterns in the case of the polka-dot diameter of 1.6 cm. In addition, it was found that yellow and green had relatively profound effects on the arrangement of the polka-dots.3. It was also proved by the method of paired comparison that the variation of polka-dot colors distinguished more remarkably differences in pattern images than their sizes did.4. From the results of the method of paired comparison, for most of the evaluation items, values of evaluation in the case of oblong patterns were higher than those in the case of square patterns.5. There was a correlation between visual evaluation and relative value and chrome on polka-dot patterns.It was found that the sensory test is quite an effective way to study polka-dot patterns.

In order to construct a way of thinking for the design of check patterns and color combinations, we reported visual evaluations for three color systems (blue, red and yellow) of checks with two-color schemes combining deep and pale same-color systems, on a total of 12 samples. In addition, two-color combinations and three-color schemes combining pale, neutral and deep same-color (blue, red and yellow) systems, were made regularly, and their visual evaluations were compared and investigated. 1) As a result of a t-test for sensory evaluation which paired two- and three-color combination samples, the three-color combination samples were quiet in the blue system, while the two-color combination samples were quiet in the red and yellow systems. And the frequency distribution of items with significant differences was shown in the t-test for sensory evaluation values and the frequency distribution was different in each color system. 2) As a result of analyzing the variances, the two-color combination variances were quite large for the color systems, but the three-color combination variances were small. It is considered that the three-color combinations were affected by color and design. 3) As a result of analyzing the principal components of the two-color combinations and three-color combinations in the blue system, the cumulative proportion of three-color combinations was higher than that of the two-color combinations. The third component of the two-color combinations concerned color, the second and third components of the three-color combinations concerned design. The three-color combination was affected by color and design.
