Pilling is a common quality problem in textiles, directly affecting product appearance and consumer experience. Whether for apparel, home textiles, or industrial textiles, anti-pilling performance is a crucial indicator of product quality. However, for companies facing numerous domestic and international testing standards, how do they choose the most suitable testing method?

Down-proofness refers to the ability of textiles (such as down jackets and sleeping bags) to prevent down or feathers from escaping through the fabric surface, seams, or pinholes. Down leakage can reduce the product's warmth, affect its appearance, and impact user experience. Common forms of down leakage include down fibers emerging from yarn gaps and down clusters penetrating the fabric or seams.

Pilling and snagging are common problems affecting the durability and appearance of textiles. Various standardized tests can assess a fabric's resistance to these defects. This article will explore the main pilling and snagging testing methods: the Martindale test, the random tumbling pilling test, the pilling and snagging test, and the ICI spike snagging test, discussing their principles, applications, testing standards, and evaluation criteria, and providing suggestions for different companies to select appropriate testing instruments.
