Abstract
The present disclosure relates to a multilayer fabric media comprising a non-woven membrane of fibers comprising at least one polymer in combination with at least one photoreactive agent mounted on a woven or non-woven substrate and coated with a light transmissible protective layer, to methods of forming such multilayer fabric media, and to articles of manufacture made therewith.
Claims20
A multilayer antimicrobial fabric media, comprising:
- a substrate layer, and
- a non-woven fiber membrane having a top surface and a bottom surface, wherein the bottom surface of the membrane is affixed to the substrate layer and wherein the membrane fibers comprise at least one polymer in combination with between 0.003 wt. % and 0.3 wt. % of at least one photoreactive agent capable of generating singlet oxygen in the presence of electromagnetic radiation.
An air filter, comprising:
- a multilayer antimicrobial fabric media filter element, wherein the filter element comprises a non-woven fiber membrane mounted on a substrate layer and wherein the membrane fibers comprise at least one polymer in combination with between 0.003 wt. % and 0.3 wt. % of at least one photoreactive agent capable of generating singlet oxygen in the presence of electromagnetic radiation.
A face mask, comprising:
- a multilayer antimicrobial fabric media filter element, wherein the filter element comprises a non-woven fiber membrane mounted on a substrate layer wherein the membrane fibers comprise at least one polymer in combination with between 0.003 wt. % and 0.3 wt. % of at least one photoreactive agent capable of generating singlet oxygen in the presence of electromagnetic radiation.
