DYEING PROPERTIES OF WOOL TREATED WITH LOW-TEMPERATURE PLASMA UNDER ATMOSPHERIC-PRESSURE

Merino wool top was treated with low-temperature plasmas of helium/arg on and acetone/argon under atmospheric pressure for 30 seconds and the n dyed with two leveling-type acid dyes, CI acid orange 7 and CI acid red 18, and two milling-type acid dyes, CI acid blue 113 and CI acid b lue 83. Dyeing rate and saturation dye exhaustion increased with the a tmospheric low-temperature plasma treatments as with the dyeing of woo ls pretreated with low-temperature plasma by glow discharge of O2 and CF4. In particular, helium/argon plasma was much more effective than a cetone/argon plasma at improving dyeing properties, except for CI acid blue 113.
