Unifi Inc. and polyester filament yarn manufacturers across North and Central America have launched YarnProof™, an industrywide initiative designed to provide physical verification of yarn origin throughout the supply chain. Powered by FibreTrace technology, the system embeds an invisible, permanent tracer into polyester filament yarn, allowing manufacturers, brands and regulators to verify origin claims, strengthen trade compliance and support regional textile manufacturing.
