Fosshield Technology Combats the Growth of Dangerous Microbes

Continuous Natural Protection Against Bacteria, Mold and Mildew

HAMPTON, N.H. - Foss Manufacturing Company, a leading designer and manufacturer of non-woven fabrics and specialty synthetic fibers, announces its Fosshield® antimicrobial technology, the premier fiber technology that safely and effectively inhibits the growth of destructive and odor-causing bacteria, mold, mildew and fungus. A unique bicomponent polyester fiber that includes a silver and copper-based, inorganic antimicrobial additive in the outer layer, Fosshield is the optimum choice for those companies looking to enhance value and performance by providing permanent, natural, and effective antimicrobial protection in textile products.

The threat of germs and fungus poses increasing concern, and microbes like bacteria, mold and mildew can quickly spread to cause odor, discoloration and deterioration on a range of surfaces if left unchecked. When woven-in, Fosshield enhances the value of any textile by combating the growth of these microbes, thereby extending product life and maintaining a hygienically clean surface.

Fosshield is produced via a patented fiber technology. Unlike other antimicrobials that are applied via topical coatings, the additive in Fosshield is extruded as part of the fiber sheath during manufacture, providing the most effective exposure to damaging bacteria and fungi. Equally as important, it will not wear or wash off.

Fosshield utilizes two of nature's own antimicrobial solutions as its active ingredients. The synergy of silver and copper ions in combination has achieved reduction rates of greater than 99.99 percent against a broad range of undesirable bacteria, fungi, mold, and yeast. The additive, from AgION® Technologies, employs a proprietary method of encasing silver and copper ions in a zeolite cage, allowing for controlled release only when needed, resulting in long-term antimicrobial action on demand. This EPA-approved antimicrobial is chemical-free, non-toxic, safe for prolonged contact with human cells, non-leaching, environmentally safe, and does not contribute to the growing concern of antibacterial resistance.

Fosshield can be blended with a variety of other fibers, ranging from cotton to rayon, polypropylene to nylon. Fosshield fiber looks and processes like virgin PET staple fiber. It will not adversely affect yarn spinning or weaving. Additional additives such as fire retardant, stain resistance agents, pigment and UV stabilizer can be added during the manufacture of Fosshield. Foss Manufacturing offers custom color matching for all of its fibers, including Fosshield.
