There are several methods for judging the quality of special industrial fabrics:

Observe the appearance. The appearance of special industrial fabrics should be flat, smooth, and free from obvious damages, stains, color differences, and other defects. The coating or composite layer should be uniform, firm, and free from peeling, blistering, delamination, and other phenomena.

Check the specification parameters. The specifications and parameters of special industrial fabrics include width, thickness, weight, density, etc., which should meet the requirements of standards or contracts. They can be measured using corresponding instruments, such as steel rulers, fabric thickness testers, electronic scales, etc.

Test physical performance. The physical properties of special industrial fabrics include strength, tear resistance, wear resistance, tear resistance, waterproofing, fire resistance, anti-corrosion, anti-static, sound insulation, thermal insulation, etc. Corresponding testing methods and standards should be selected based on different functions or uses, such as ISO 1419, AATCC 111, AATCC 169, AATCC 186, etc.

Conduct accelerated aging test. The accelerated aging test of special industrial fabrics is to simulate the effects of temperature, humidity, light, oxidation, ozone and other factors on their actual use environment, evaluate their aging degree and durability, and use different test methods and standards, such as AATCC 111, AATCC 169, AATCC 186, ASTM D5427, FZ/T 1008, FZ/T 75002, etc.
