Problems solved by technology

The narrow-band light sources required for sub-band photoaging experiments are 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.

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] combine Figure 1 to Figure 5 , The main inventive structure of the visible light sub-band textile light aging tester has four parts: the experimental chamber 1, the lower chassis 5, the upper cover plate 8 and the sample tank 13.

[0021] The main structure of the visible light sub-band textile light aging tester is made of heat-insulating wood. The experimental cavity is a drum with an inner diameter of 20cm, a thickness of 1cm, and a height of 40cm. The waist is 14cm away from the lower end. Twelve holes 3 with a diameter of 14 mm are drilled at a distance, and six to eight mounting holes are respectively opened on the lower part and the top of the drum. The central axis of each light transmission hole 3 is all aligned with the filament of the incandescent lamp 6 mounted on the lower chassis 5 . Visible light narrow-band filters are respectively installed...

Abstract

The invention discloses a light aging test instrument, which includes a test cavity, a bottom baseplate, the top cover board which is fixed on the bottom and the top of the test cavity respectively. A lamp socket which fitted with a lamp is right on the centre of the base plate, the photo permeable holes are set at the same height on the side wall of the test cavity. A visual light narrow wave band filter sheet is in the photo permeable hole, and the sample trough is fitted on the photo permeable hole. The test instrument has a compact structure, easy to disassemble and assemble, inflexible for employ, with low cost of the production.

Description

technical field [0001] The invention relates to a performance testing instrument for textiles, in particular to a textile photoaging tester. Background technique [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 ...
