ANTI BACTERIAL NANO FIBRES

Nanofibers

• Nanotechnology has been employed to develop fibers possessing a permanent antibacterial performance. For example, polypropylene (PP) in hygiene and medicare applications. • The fibers developed are bicomponent items with a PP core and PP/silver sheath. The particles have an average size of 30 nm. • PP/silver component produced an excellent antibacterial effect on microorganisms such as Staphylococus aureus. http://www.eng.auburn.edu/~tzengy/ELEC7970%20Summer%202003/Student%20Presentations/28%20Nanotechnology%20in%20textiles%20by%20X%20Ren_files/v3_document.htm

PP core

PP/silver fibers have dyeing problems. But it can be overcomed by using Montmorillonite nanoclay.A cationic surfactant is introduced into the nanoparticels to create dye sites. The treated nanoclay is then blended with the PP polymer before the fibers are extruded.
