The circular trajectory pilling tester uses a linear guide as a sliding gauge to test the pilling condition of woolen fabrics, synthetic cotton, blended, knitted, and woven fabrics, in order to identify product quality and process effects.

Applicable standards: GB/T4802.1, JIG040, DIN53863.2

During the wearing process, fabrics are prone to pilling and fuzzing due to internal factors such as fiber types, fabric structure, and finishing, as well as external factors such as friction and snagging. This seriously affects the wearability and aesthetic performance of textile clothing. There are currently four testing methods for pilling of textile and clothing in China: circular trajectory method, modified Martindale method, pilling box method, and random rolling method. The corresponding method standards are GB/T4802.1-2008, GB/T4802.2-2008, GB/T4802.3-2008, and GB/T4802.4-2009. According to statistics from testing institutions, the circular trajectory pilling method is more frequently used among these testing methods, and the compass trajectory pilling tester is a testing experimental instrument.
