Foss Manufacturing Company

Foss Manufacturing Company, now operating as Foss Performance Materials, is a specialty synthetic fiber and non-woven fabric manufacturer that plays a critical role in the medical and healthcare material sectors. The company is best known for its proprietary Fosshield technology, a patented antimicrobial system that embeds silver and copper ions directly into the fiber matrix to provide permanent protection against a broad spectrum of bacteria and viruses. This technology was instrumental in the development of the SpectraShield 9500 N95 mask, the first antimicrobial respirator to receive FDA 510(k) clearance. Beyond PPE, the company produces high-performance materials for hospital textiles, wound care, and specialized filtration systems. Following its acquisition by AstenJohnson in 2017, the company's healthcare and industrial divisions were integrated into the AJ Nonwovens business unit. The company maintains major manufacturing facilities in Hampton, New Hampshire, specializing in needlepunch non-woven solutions.
