Color conspicuity of cloth in terms of weaving structure and its use for safety wear

摘要本研究的目的是利用色彩显著性设计老年人和儿童的安全服装。在这个实验中，测量了衣服的编织形式对颜色显著性的影响。在一个正常的房间里放置一块布片，由一个额外的光源局部照亮。当照明增加时，布作为放置在房间里的物体首先显得不自然。这一点定义了照度边界。为了进一步增加布料现在看起来最漂亮，这定义了美丽的边界。测量了两种不同织造结构的棉衣，“平纹织造”、“斜纹织造”和“缎纹织造”三种典型形式。每种编织用了红、黄、绿、蓝、白五种不同的颜色。结果表明，缎纹织物的边缘照度一直较低，表明缎纹织物比其他编织形式更显眼，可用于老年人和儿童的安全服。布料的色彩呈现模式的变化在亮度上得到了很好的体现。当给物体颜色上限值的照度一定的恒定照度时，它就变成了光源颜色模式。在“美丽”点的亮度上，个体之间存在很大差异。然而，所有的考生都觉得“美”在高于物体颜色的上限值。

The purpose of this study is to design safety clothes for the elder lies and children by utilizing color conspicuity. In this experiment the effect of weaving form of clothes was measured for color conspicuity. A cloth patch was placed in a normal room and it was illuminated locally by an additional light source. When the illumination was increased the cloth first appears unnatural as an object placed in the room. This point defines the illuminance border. For a further increase the cloth now appears most beautifully, which defines the beautiful border. The two borders were measured for cotton clothes of different weaving structure, "plain weave", "twilled weave" and "satin weave", three typical forms. Five different colors, red, yellow, green, blue, and white were employed P for each weave.The results showed that the border illuminance was always low in satin weave suggesting the satin can be used for safety clothes to be worn by elder lies and children because they can be more conspicuous than other weaving forms.The change of color appearance mode of the cloth was well shown in the brightness. When giving the illuminance with the upper limit value of the object color some constant illuminance, it changed into the light source color mode. There was a big difference among individuals in the illuminance of the point that seems "beautiful". However, all the examinees felt "beautiful" in above the upper limit value of the object color.
