Abstract

Novel nanofiber-enhanced textiles have been developed through electrospinning and plasma processing. The novel bioactive nanofibers feature multiple functionalities including: i) high barrier efficiency; ii) excellent detoxifying efficiency against toxic chemicals; and iii) antimicrobial activity against gram (+) and gram (-) microorganisms. The nanofibers were deposited on textile substrates to form novel layered composite systems. The adhesion between nanofiber layer and substrate textiles can be remarkably increased by both conventional and hybrid plasma treatment. The plasma-treated nanofibers showed excellent performance and durability in a peeling test, a Gelbo Flex test and an abrasion test. The nanofiber-enhanced textiles have shown promise for use in protective clothing and wound dressings. Further research is being conducted to extend the health related applications of these materials. Novel nanofiber-enhanced textiles have been developed through electrospinning and plasma processing.
