Prevent insulation loss. This feature ensures high-density fabrics and secure seams keep down and feathers contained for lasting thermal performance.
The Importance of Down Retention
For high-performance outerwear and bedding, the ability to retain down and feather filling is essential for both thermal efficiency and aesthetic appeal. "Down leakage" occurs when small feathers or down clusters migrate through the fabric pores or needle holes in the seams. Effective anti-down leakage properties ensure that the insulation remains trapped within the baffles, maintaining the product’s loft (fill power) and preventing the messy "shedding" that can frustrate consumers and diminish garment life.
Precision Testing and Global Standards
To verify that a textile is truly "downproof," materials undergo rigorous mechanical testing to simulate real-world wear and compression. Key international standards include EN 12132-1 and EN 12132-2, as well as FTMS 191 Method 5530. These methods involve placing down-filled cushions inside a rotating chamber or subjecting them to repetitive rubbing cycles. After a specified duration, technicians count any escaped particles to determine the fabric's resistance level. A high-performance result typically requires a minimal count of escaped down or feathers, proving the fabric's weave density and seam integrity are superior.
Validation through the High Performance Mark
By meeting selected technical benchmarks, your textile and apparel products become eligible for the Intertek High Performance (HP) Mark’s Anti-Down Leakage. This mark serves as a ‘proof of performance’ by validating that your product meets the HP Mark standards. You can display the mark on product tags, brochures, packaging, websites, and in both online and offline stores across multiple channels, confidently signal to consumers that the performance claims of your products are verified.
