Dow Debuts SILVADUR™ Antimicrobial Textile Treatment

Dow Microbial Control, a business unit of The Dow Chemical Co., Midland, Mich., has introduced a silver-based antimicrobial treatment for textiles and apparel.

SILVADUR™ technology features a unique polymeric delivery system that transports and secures silver ions onto a fabric's surface to inhibit bacteria growth. Dow reports Silvadur is a good alternative to traditional silver particle-based antimicrobial technologies, and offers unsurpassed durability and reliability in controlling bacteria.

Dow supplies the antimicrobial in an easy-to-apply liquid formulation that may be applied using a variety of methods, including pad and exhaust applications, to fabrics containing both natural and man-made fibers. Silvadur is compatible with a range of common textile chemical additives, detergents, and finishing treatments, and can withstand more than 50 washings, the company reports. In addition, the antimicrobial's polymeric nature, low-dosage profile and formulation makeup make it a good alternative to existing silane quaternary ammonium-based technologies, according to Dow.

"Based on Dow's long-time leadership and expertise in microbial technology and the results of our extensive third-party testing, we're confident that Silvadur technology offers game-changing potential for fabric and textile manufacturers, retailers, brand owners and consumers of sports and fitness apparel, socks, intimate apparel and home textiles," said Karel Williams, global strategic marketing manager, Dow Microbial Control. "We're eager to provide samples to potential manufacturing and brand partners around the world so they can see Silvadur's highly efficient and performance-based benefits firsthand. Research demonstrates that consumers are willing to pay more for textile products offering improved freshness, and Silvadur's numerous benefits help increase the value of textiles, apparel and garments treated with the product."

Dow reports the skin-friendly antimicrobial technology also is a sustainable solution, as it does not release silver particles into the environment; may be recycled and reused during processing applications because it is inherently stable to light and water-soluble; and helps processing plants reduce overall raw material purchases as well as energy and water usage.

Silvadur antimicrobial is registered with the U.S. Environmental Protection Agency and registered to meet REACH requirements in the European Union, and has been certified by The International Oeko-Tex Association, Switzerland. In addition, its active ingredient is notified and supported under the EU Biocidal Products Registry.
