The broader/commercial impact of this Small Business Technology Transfer (STTR) Fast-Track project is to develop, and commercialize, a novel method of tracing and authenticating textile materials. Counterfeit textiles are a growing problem, with $179 million of clothing and apparel seized by United States Customs and Border Protection in 2024. These counterfeit materials not only hurt retailers and, ultimately, the United States economy, but also can contain hazardous chemicals. A key challenge currently for detecting counterfeit items is the amount of time required to test and verify that the products are genuine. The innovation to be developed by this proposal would provide a cost-efficient, non-toxic additive that integrates into existing textile manufacturing processes and permits instantaneous verification without costly laboratory testing. The proposed technology is a fraction of the cost of existing solutions on the market, and would be manufactured domestically creating safe, high-paying jobs. The low production cost coupled with a seamless digital tracking and verification system will provide a durable competitive advantage and fuel sustainable company growth. Textile and apparel manufacturers and brands are the initial customers of this technology, and its development would add to the growing revitalization of the U.S. textile industry driven by innovation.
