Cordura Fabric with Subtle Thin-Film Modifications Used for the Enhancement of Barrier Properties Against Toxic Gases (Part I)

This study describes the modification of polyamide fabric with the commercial name Cordura to create a material that is more resistant to the permeation of toxic gases and compound vapors while remaining permeable to water vapor and air. The surface of Cordura was modified by applying a very thin film, deposited from a vapor organic phase at room temperature under the influence of γ-radiation. The permeability of the modified fabric to water vapor, organic vapors, organic dyes, and toxic substances (sulfur mustard gas) was determined and compared to the properties of the unmodified fabric.
