Outline of Final Research Achievements

The application of atmospheric pressure plasma jet (APPJ) to pre-treatment of inkjet dyeing was discussed. The water wicking into fabrics of cotton, wool, silk and polyester promoted after the APPJ treatment, due to oxidation of fiber surfaces. The effect of the APPJ pre-treatment on the inkjet dyeing of wool fabric with acid dyes was examined. Especially for short steaming time, the Kubelka-Munk function value of the dyed fabric as a measure of the colour deepening increased due to the pre-treatment by the APPJ compared with the chemical treatment. It was confirmed from image analysis that the APPJ treatment did not cause bleeding and uneven dyeing. The colour fastness of the dyed fabric to washing and rubbing did not reduce due to the pre-treatments by APPJ as well as chemicals. It is expected that introduction of the APPJ pre-treatment to the inkjet dyeing is effective to reduce environmental impact and to improve energy efficiency and productivity in the dyeing process.
