Yarn maker O'Mara Incorporated is to incorporate SmartSilver anti-odour and antimicrobial additives in its Eco-Fil yarns, which are made from 100% recycled post-consumer bottles.

SmartSilver from NanoHorizons is a nanotechnology treatment that imparts permanent anti odour/antimicrobial properties to natural and synthetic fibres and fabrics.

The two companies say the yarns enable manufacturers to offer performance apparel that is both high-performance and environmentally responsible.

Dennis Schneider, director, sales and marketing, NanoHorizons, adds that SmartSilver ingredients are made using lower-grade ores from silver mining that would otherwise be disposed of as waste.
