How ugly are faded shoes, and how important of the Light Discoloration (UV) Tester?

We are often dissatisfied with some shoes that have faded. Sometimes we feel very 

ugly because of the discoloration of our shoes, and we dare not wear the discolored 

shoes, which makes us feel very sick, Light Discoloration (UV) Tester is a measure of 

the UV resistance of the sole and upper materials. The test equipment conforms to 

ASTM, JIS, BS, ISO, ICE, UL ASTM-D1148, HG/T3689, and other international 

standards, and is mainly used to test the discoloration resistance of shoe materials. 

The principle is that it is equipped with sun lamps and heating devices to simulate 

the natural environment. Expose the sample for a certain time, check the color 

change on the surface of the sample, and then understand the anti-yellowing ability 

of the sample under sunlight, which plays an important role in testing white and

light-colored upper materials, sole materials, leather, and other materials.
