æ°™Lighting weatherproof test box for the detection of textiles

样品The sample of the textile material used for testing in the light detection test chamber and the corresponding comparison standard should be exposed to the corresponding light source at the same time. The light fastness of the test article can be measured in three ways: by comparing the color change of the exposed portion with the marked contrast portion of the test sample, using the AATCC color change height to compare with the unexposed raw material; or by color Measuring instrument to measure. A series of comparisons with the AATCC Blue Wool Lightfastness Standard were made under simultaneous exposure conditions to obtain a gradation of lightfastness.
