technical field

[0002] At present, the photoaging experiments of textiles are mainly carried out by ultraviolet photoaging experiments, and the photoaging experiments in the visible light band are full-band aging experiments. The narrow-band light source required for sub-band photoaging experiments is also difficult to buy. The commonly used lasers are mainly concentrated in the red and infrared bands. In the short-wavelength visible light band, there is no laser light source that can be used for photoaging. Therefore, it is currently impossible to carry out photoaging experiments with different bands of visible light. The academic community is still unclear about the impact of different bands of visible light on textiles. There is an urgent need for instruments for narrow-band aging experiments in this band to study the effects of different bands of visible light on textiles. The influence of light in various bands on textiles. Contents of the invention

[0007] The experimental chamber 1, the lower chassis 5, and the upper cover 8 are all heat-insulating, heat-resistant and opaque materials, and their inner surfaces are all coated with a white reflective layer. The lower part of the experimental chamber 1 touches the ground, the lower chassis 5, and the upper cover One or more ventilation openings 4 are arranged on the plate 8, and the number of ventilation openings 4 can be one or more evenly or unevenly distributed.
