Does the use of physical tracing technology to verify product origin increase your trust in brands?
Polyester filament producers in North and Central America have introduced YarnProof, a verification initiative that uses FibreTrace technology to confirm the origin of textile materials. Ten companies have joined the effort to protect supply chain compliance.
Why it matters
The initiative aims to strengthen trade integrity and provide physical evidence of origin to verify compliance with regional trade requirements. This move supports producers in maintaining adherence to established manufacturing standards.
Ten manufacturing companies have formed this collective to integrate physical tracing into their supply chains. This initiative provides a verification framework that covers production across both North and Central American regions.
The players
Unifi, Inc.
Unifi, Inc. is the organization that holds the registered trademark for the YarnProof technology.
The details
Producers embed an invisible tracer into polyester filament yarn during the extrusion process, which can then be detected by handheld scanners to link materials to specific sourcing records. YarnProof is a registered trademark of Unifi, Inc. and is designed to align with CAFTA-DR and USMCA yarn-forward requirements.
