Fibrous antimicrobial materials, structures, and barrier applications

A barrier structure comprising:

• at least one layer of a woven or nonwoven fibrous antimicrobial material which comprises an antimicrobial polymeric material comprising a miscible blend of an antimicrobial bisguanide compound and at least one thermoplastic polymer, the miscible blend being from about 1% to about 25% by weight antimicrobial bisguanide compound,
• wherein the at least one layer is spray impact and fluid penetration resistant.

An antimicrobial face mask comprising:

• a fibrous antimicrobial material which comprises an antimicrobial polymeric material and comprising a miscible blend of an antimicrobial bisguanide compound blended with at least one thermoplastic polymer, the miscible blend being from about 1% to about 25% by weight antimicrobial bisguanide compound, wherein the fibrous antimicrobial material is woven or nonwoven;
• and
• a means for securing the fibrous material over a person's mouth and/or nose.

An antimicrobial wound dressing comprising:

• a fibrous antimicrobial material which comprises an antimicrobial polymeric material comprising a miscible blend of an antimicrobial bisguanide compound blended with at least one thermoplastic polymer, the miscible blend being from about 1% to about 25% by weight antimicrobial bisguanide compound, the fibrous antimicrobial material being woven or nonwoven;
• and
• a means for securing the fibrous antimicrobial material over a wound of a human or animal.

A device for antimicrobial treatment of a fluid comprising a filter core with at least one fibrous antimicrobial material wound around the filter core, wherein the fibrous antimicrobial material comprises an antimicrobial polymeric material comprising a miscible blend of an antimicrobial bisguanide compound blended with at least one thermoplastic polymer, the miscible blend being from about 1% to about 25% by weight antimicrobial bisguanide compound.
