California-based textile company Pi-Ray America on Wednesday unveiled a revolutionary new fibre which uses embedded mineral content to beat infection and odour and improve circulation.

The firm said tests show the socks, thousands of pairs of which have been sent to military units in Iraq, beats bacteria including Staphylococcus, Bacillus Subtillis, klebsiella, and Pseudomonas areoginosa, and various types of fungi including Candida albicans, and Athletic fungus.

"Pi-Ray fibre could solve many common problems that occur on the battlefield as well as in the VA Hospital system, and would be a fiscally responsible choice," said Pi-Ray president Loren Chang.

"Because of its unique embedded anti-bacterial and anti-fungal properties, this everyday wearing apparel helps reduce secondary infections in government hospitals, and the foot discomfort suffered by our troops in the field.

"Since the minerals are embedded, not coated, bonded, sprayed or treated as most other products, Pi-Ray Socks and its healing effects will last longer," she added.
