Preparation of a Nanostructured Nonwoven Material Using Plasma

Issues associated with the development of nanostructured nonwoven fibrous material (NFM) using a nonequilibrium low-temperature plasma are discussed. The hydrophilicity increased for the first layer based on viscose fiber (lyocell) on the facing side and the second layer of moisture impermeable polyester film on the inner side, which prevented penetration of liquid media and bacteria because their surfaces had few active groups. An evaluation of the hydrophilicity of the NFM properties found that this effect persisted over time. Therefore, preliminary activation of the NFM surface by a flux of nonequilibrium low-temperature plasma was proposed to increase the number of active groups on their surface. Modification of the NFM increased the tensile load by 19.7%, the relative elongation at break by 34.2%, and the sorption up to 61.6% as compared to control samples.
