Available Technology

Novel, permanent antimicrobial cotton fibers are produced via in situ synthesis of silver nanoparticles inside the fiber. The silver nanoparticles encased within the fiber are leach-resistant against continuous launderings and serve as a reservoir for the release of biocidal silver ions, regenerating the antimicrobial surface wash after wash. This new nanotechnology tailored for cotton chemistry and structure is included in the invention.

Benefits
• Pure: consists of only cotton and silver nanoparticles; no chemical binders or coating matrices
• Powerful: kills 99.99% of both Gram-positive and Gram-negative bacteria
• Durable: retains the same antimicrobial function even after 50 laundering cycles
• Versatile: can be blended in the fabrication of all woven or nonwoven textile products

Applications
• Hospital textiles, socks, sportswear, military apparel, wound dressing, home textiles, hygiene products, and packaging
