Gray scale image analysis is used to investigate crease appearance created by applying a load of 6 kgf for 60 minutes to regularly or irregularly folded cotton cloth. The angular second moment, contrast, correlation and entropy extracted from the gray level co•occurrence matrix are measured as visual feature parameters. The fractal dimension is determined from the fractal analysis of the relief of the curved surface of the gray level image. The image information parameters except for contrast tend to change more or less rapidly with the initial increase of numbers of folding, after then, these parameters are followed by the moderate change. Contrast increases linearly with numbers of folding. These image information parameters are found to be useful for characterizing the visual features of creased cloths. Crease appearance and difference between regularly and irregularly crease of cotton cloth are discussed in the relation to the visual features contained therein, such as uniformity, local variation, linearity, information content, complexity and so on.

  It has been reported that Japanese female students are inclined to want large numbers of casual and low-priced clothes and to wear them in the same manner as others. They also want to 'act' like them. Japanese females like fashion images of “simple”, “pretty” and “casual”. In order to elucidate whether or not their ideas and behaviors are peculiar to the Japanese, we investigated the fashion sense of Italian female students by questionnaire survey and compared them with those of Japanese female students. The questions asked are as follows : how much do you pay for clothes on a monthly basis? ; what are the adjectives that correspond to your idea of fashion? ; who or what do you hold in consideration when you select your style of fashion? ; which are the brands that you buy most frequently? ; which are your favorite brands? ; which are the closest to your idea of fashion and life-style? We analyzed the results about the idea of fashion and life-style by factor analysis. It was found that Italian female students are inclined to wear good and high-priced clothes for the long-term, and to wear clothes different from others. They also behave themselves on the basis of their own ideas, and also have fashion images of “particular”, “feminine”, and “simple”.

　分散染料1,4- ジアミノアントラキノンと2鎖型の陽イオン界面活性剤N,N- ジドデシルジメチルアンモニウムブロマイド染浴にポリ酢酸ビニルエマルジョン (PVAc-E) を加えた系において, ポリカプロラクタム (ナイロン6) 布の染色速度について検討した。また, この系で染色する際の最適な染色条件についても検討した。その結果, 実用上必要な染色液中のPVAc-E濃度, 液温, 染色時間はそれぞれ, 0.086wt%, 70℃, 30分であった。
