Fabric Downproof Tester(Rolling Box)

The Fabric Downproof Tester (Rolling Box) is designed to evaluate the down-proof performance of textiles by simulating friction and impact stresses similar to real-world use. It ensures that fabrics used in garments, bedding, and outdoor products prevent feather leakage and meet quality standards. The instrument combines automation, precision, and durability, and operates in compliance with international down-proof testing standards.

Application

The tester is suitable for evaluating down-proof performance in textiles for jackets, comforters, sleeping bags, and other down-filled products. It is ideal for quality control, R&D, and production inspection, ensuring that materials resist feather penetration and maintain integrity under repeated use.
