Antibacterial Evaluation of Cotton Fabric Pretreated by Microwave Plasma and Dyed with Taiwan Folkloric Medicinal Plants

摘要

Seventeen Taiwanese commonly used medicinal plant dyes were extracted and used for dyeing cotton fabric pre-treated with extensible antenna-coupling microwave plasma system. The anti-Staphylococcus aureus' ability and washing fastness of the dyeing cotton fabric were compared with and without plasma pre-treatment. The plasma condition was set at oxygen pressure 0.2 Torr, power 800 W and 5 sec treatment time. After the plasma pre-treatment, the results showed that 13 plant-dyed cotton fabrics increased the anti-Staphylococcus aureus inhibition zone. As of washing fastness of plasma treated plant dyed cotton fabric, the green tea, gromwell root and cornus fruit showed the best rating of 4.
