Traceability

YarnProof™, powered by FibreTrace® technology, embeds an invisible and permanent tracer into polyester filament yarn during extrusion. This creates a verifiable signature that travels with the material throughout the supply chain. The tracer remains with the material throughout its lifecycle to transform origin claims into provable facts.

Verification

Proof That Travels with the Fiber.

The tracer can be immediately-detected using a proprietary FibreTrace handheld scanner at designated points across the supply chain, including yarn, fabric, and finished goods. YarnProof transforms polyester filament yarn origin verification from a paper-based process into a science-based system.

Detection

Verification Built In. Evidence You Can Trust.

The targeted patented technology is detectable from yarn through finished article to verify the origin of polyester filament yarns produced in North America, Mexico, and Central America. Additional lab testing is available to offer further validation for low-content articles.

Assurance

Transforming Origin Claims into Provable Facts.

By linking physical verification to origin claims, YarnProof supports compliance with the yarn-forward requirements of the CAFTA-DR and USMCA trade agreements. Working alongside existing documentation and certification systems, YarnProof adds a layer of verifiable evidence that strengthens trade integrity, protects compliant supply chains, and supports regional manufacturing.
