衣服のスポット汚れの視覚的評価に関する研究

摘要

The authors focused on stains which are the most common color factor causing abandonment of clothes and have studied color factors relating to the sense of conspicuousness of stains. Following three experiments have been conducted. Firstly, 105 subjects were asked to select a color which they find it may most easily stained, from among textile samples prepared with cotton broad cloth in 19 different colors. Secondly, other subjects were asked to rank the conspicuousness of stains which has been actually stained on textile samples. Thirdly, the subjects were asked to evaluate the degree of conspicuousness of stains after washing. The stains used for the experiment were seven different types including "soy sauce", "foundation", "black ink", etc. which had been given as types of stain liable to cause abandonment in the responses to the questionnaire. As a result of a multiple regression analysis using the obtained data, the colors which the subjects presumed liable to make stain conspicuous proved to be different from the colors with which the stain was really conspicuous. Furthermore, it became clear that stains are more conspicuous on a cloth of high brightness and bluish color rather than stains on a cloth of reddish color.%衣服の廃棄に繋がる色彩要因として最も多いスポット汚れを取り上げ，汚れの目立ち感に関与する 色彩要因について検討を行った． 実験は，105名の被験者により，まず19色の綿ブロードで作成したテキスタイルの見本を見て，汚 れが目立ち易いと思う色を選出させた．その後，実際に汚れを付着させたテキスタイルの見本を見て 汚れが日立つ順位をつけさせ，さらに洗濯した後の目立ちの評価も行った．実験に使った汚れは，ア ンケートの結果，廃棄に繋がりやすいと回答された「醤油」「ファンデーション」「墨汁」等7種類を用いた． 得られたデータを用いて重回帰分析を行った結果,被験者が予想した汚れの目立ち易い色と，実際 の汚れの目立ちとは異なる結果であった．また，明度は高く，赤系よりも青系の布地の方が汚れが目 立ちやすいことが明らかになった．
