Abstract
Anti-microbial wound dressing and method of producing the same. The wound dressing comprises a non-woven fabric produced by hydroentanglement of a blend of fibres, said blend being formed by first fibres which are coated with elemental silver or contain silver and second fibres which are essentially free from silver. The wound dressing will retain its antimicrobial properties over extended periods of time, and it is suitable for sustained release of silver.
