Improvement of Printing Properties of PET Micro Filament Fabrics Using Low Temperature Plasma Technology(I)

저온 plasma 기술에 의한 PET 극세사직물의 날염성 개선(I)

In order to improve dyeability of poly(ethylene terephthalate)(PET) micro filament fabrics, the effect of the prior oxygen low temperature plasma on the subsequent dyeing(deep dyeing, printing) was examined in various conditions. The apparent concentration of dyed PET micro filament fabrics was increased by $O_{2}$plasma treatment. Higher discharge power levels and higher reactor pressure values created more significant effect. The wettability was significantly increased by $O_{2}$ plasma treatment. Therefore, it is predicted that introducing hydrophilic group on the surface of material can improve the apparent concentration of PET micro filament fabrics.
