摘要：

针对光致变色纺织品变色性能检测方法缺失的问题,以商品化的光致变色纺织品为研究对象,通过模拟光致激发环境,采用手持式分光测色仪测量样品的颜色变化,研究光致变色纺织品的变色和恢复机制,建立光致变色纺织品的检测方法。结果表明:受光照射后样品颜色变化呈先深后浅趋势,并在照射3 min左右达到稳定;太阳光辐照度不会影响样品的变色与恢复过程,采用AM1.5滤光片,辐照度为1 000 W/m ²的标准太阳光作为激发光源照射样品5 min,并遮光恢复30 min,分别使用人眼和仪器评级测定样品的变色和恢复色差,均可有效检测光致变色纺织品的变色性能;该检测方法简单易操作,可靠性强,可标准化。

Abstract:

In order to provide the detection methods for the chromogenic performance of the photochromic textiles, taking commercial photochromic textiles as research objects, by simulating the excitation environment and measuring the color change of the commercial photochromic textiles with a portable spectrophotometer, the discoloration and recovery mechanism were studied and the detection methods of photochromic textiles were established. The results show that the color change of the samples increases first, then decreases and reaches stable after 3 min under irradiation. The discoloration and recovery processes are not influenced by the solar irradiance. One standard sunlight is provided as an excitation light source by using an AM1.5 filter and adjusting the irradiance to 1 000 W/m ². The samples are irradiated for 5 min, and recovered for 30 min. The discoloration and recovery chromatic aberration of the photochromic textiles are determined by human eyes and instrument assessment to effectively detect the chromogenic performance of the photochromic textiles. The detection methods are simple, easy to operate,highly reliable, and can be standardized.

Key words: photochromic textile, chromogenic performance, detection method, eye rating, chromatic aberration measurement
