However, the traditional fabric density detection method has significant shortcomings. For example, although manual pilling test can quickly evaluate fabric quality, the results are easily affected by subjective factors of operators, different testers may draw different results for the same fabric, and even the same tester may produce differences when testing the same sample at different times.
