Feature of Tabletop Light Fastness Tester TF421:
- Tabletop Light Fastness Tester TF421 is a powerful xenon instrument with an affordable price for performing accelerated lightfastness and light stability tests. Besides, the tabletop light fastness tester is designed as a tabletop unit with a microprocessor controller for easy operation. Moreover, the instrument is mainly applied in textile testing, such as cotton, woven fabric, and knitted fabric.
- Tabletop Light Fastness Tester TF421with testing principle:
- Colorfastness to light is the firmness degree to which the color of textiles is under the exposition of sunlight or simulated sunlight. The test of color fastness to light: arrange the sample with a set of blue wool standards samples (8 pieces) in a prescribed manner at first. Then cover a part of the specimen and the blue standard sample with an opaque covering in the prescribed proportion.
- Expose the samples under specified conditions such as not being exposed to rain, etc. When the color difference between the exposed and unexposed parts of the sample is equal to a certain level of the discoloration gray card, or the color change of the specified blue standard sample is equivalent to a certain level of the discoloration gray card, stop the sun exposure. Finally, remove the cover, and place the sample and the blue standard sample in the dark for 4H. Then we can evaluate the colorfastness level of the textile with the specified light source.
