The Impregnation of Corona Activated Polypropylene Non-woven Fabric with Thymol in Supercritical Carbon-dioxide

Abstract

This study discusses the possibility of impregnation of corona pre-treated polypropylene (PP) non-woven fabric with thymol in supercritical carbon dioxide. Corona treatment of PP fibers caused significant morphological changes. FTIR measurements revealed that ester bond between OH group of thymol and carbonyl group of corona treated PP fibers has been established. Antibacterial activity of corona activated PP non-woven fabrics impregnated with thymol was tested against Gram-negative bacteria E. coli and Gram-positive bacteria S. aureus. Maximum bacteria reduction was provided.
