20090092645 | Radiation Method for Fabrication of Nano-sized Compound Antibacterial Fabric Textile - The invention discloses an innovative process to produce highly antibacterial nano-composite fabric textile containing silver metal compound. The process mainly uses high-energy D-ray radiation to modify silver type of bactericides and graft or crosslink them onto Nylon or PET fiber surface to produce excellent antibacterial textile products. The mechanism uses silver nano-compound as performance additive and through Co-60 irradiation technique reduces and firmly fastens silver particles onto Nylon or PET (Polyethylene Terephthalate) fiber material. Because the inorganic silver type bactericides actively interact with enzymes in bacteria or destroy cell walls to achieve good bactericidal effect, the radiation process does not need initiators or other additives. So the process is simple and effective. The test results prove excellent bactericidal power and potential value in household or medical textile products. | 04-09-2009 |
