ANTIMICROBIAL FIBER, FABRIC AND WOUND DRESSING CONTAINING NANO METAL AND PREPARATION METHOD THEREOF

摘要

The present invention discloses an antimicrobial fibre, fabric and wound dressing that incorporate nano metal and the preparation method thereof. Nano metal particles are homogenously distributed within the fibre structure or surface, and, the fibre does not contain protective colloid for the prevention of agglomeration of nano metal particles. The nano metal particles are in an amount of 1.1 % to 20% by weight. The fibrous wound dressing has the ability to continuously release sufficient amount of silver ions and is especially suitable for the management of chronic wounds. It can effectively prevent various bacteria and microbial infections.
