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

本研究旨在利用色彩的醒目性，设计老人及儿童安全服。在这个实验中，服装的编织形式的影响，颜色的显着性进行了测量。将布片放置在正常房间中，并通过额外的光源局部照明。当照明增加时，布首先作为放置在房间中的对象出现不自然。该点定义照度边界。为了进一步增加布现在看起来最漂亮，这定义了美丽的边界。对平纹、斜纹和缎纹三种典型组织的棉布服装的两种边界进行了测量。结果表明，缎纹织物的边界照度始终较低，比其他织物更能突显织物的颜色，可用于老人和儿童的安全服，织物的颜色表现模式的变化在亮度上得到了很好的体现。当给定具有物体颜色上限值的照度一定恒定照度时，就转换为光源颜色模式。个体之间在看起来“漂亮”的点的照度上存在很大差异。不过，所有考生都觉得“美”在物体颜色上限值以上。

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.
