Effects of Insolation on Optical Properties of Tricot Invisible Curtain

In order to analyze the optical properties of different dyeing invisible curtain after long time insolation in xenon arc lamp which stimulated realistic sunlight conditions. Four different light color dyeing (yellow,blue,purple,and peach )Tricot Invisible Curtains were selected. The color and the optical properties,including the light transmittance and reflectance of the technical face and back side of samples in the ultraviolet and visible band, were tested and analyzed.The results showed that the color of all samples had different degree of fading after insolation, the anti-ultraviolet and transmittance properties were improved. The light-admitting and privacy-keeping functions of samples can keep stable after long time insolation and yellow sample keep the best performance of anti-peep properties.
