Silver containing wound dressing

摘要

A wound dressing having anti-microbial activity comprises a first fiber capable of bonding with silver (1) cations. The wound dressing comprises a blend of the first fiber to which silver (1) cations are bonded and a second fiber which is substantially free from silver. The wound dressing comprises from 0.01 to 5.0 percent by weight of silver (1) cations, based on the weight of fiber.

1. A wound dressing comprising gel-forming fibers having ant-imicrobial activity, comprising a first fiber which is gel-forming and substantially insoluble in water having silver (I) cations bonded thereto and discoloring on exposure to light, wherein the wound dressing consists of a uniform blend of the first fiber and a second fiber of lyocell which is substantially free from silver, said wound dressing comprising from 0.01 to 5.0 percent by weight of silver (I) cations based on the total weight of first and second fibers, whereby the discoloration of the blend on exposure to light is lessened compared with the discoloration on exposure to light of a batch of the first fiber having the same average amount of silver cations present as is present in the blend.
