摘要:

The sterilization of the simulated unearthed silk fabrics using an atmospheric pressure plasma jet (APPJ) system employing Ar/O2 or He/O2 plasma to inactivate the mycete attached on the silk fabrics is reported. The effects of the APPJ characteristics (particularly the gas type and discharge power) on the fabric strength, physical-chemical structures, and sterilizing efficiency were investigated. Experimental results showed that the Ar/O2 APPJ plasma can inactivate the mycete completely within 4.0 min under a discharge power of 50.0 W. Such an APPJ treatment had negligible impact on the mechanical strength of the fabric and the surface chemical characteristics. Moreover, the Ar ions, O and OH radicals were shown to play important roles on the sterilization of the mycete attached on the unearthed silk fabrics.
