Fabric Down-Proof Impact Tester (Impact Method)

The Fabric Down-Proof Impact Tester uses a controlled impact method to evaluate the anti-drilling performance of down-containing fabrics. The instrument simulates real-world compression shocks on sample bags filled with feathers or feather blends, providing quantitative data on fabric down retention and durability. It is widely used in quality control for down jackets, duvets, and other feather-filled products, ensuring compliance with industry standards for down-proof performance.

Application

This tester is ideal for evaluating all types of down products, including duvets, pillows, jackets, and other feather-filled textiles. By simulating repeated compression impacts, it helps manufacturers ensure the fabric prevents feather leakage and maintains product quality.
