The effect of pretreatment with atmospheric helium plasma on colour yields of printed wool fabric
Prints on untreated wool fabric appear relatively pale and frosty due to the presence of uncoloured or pale fibres on the print surfaces. Prints with maximum brightness and depth can only be obtained on wool that has been pretreated. The most effective pretreatment allows print pastes to wet the fabric relatively easily and also promote significant uptake of dye on the surface of fibres during drying of the print. Oxidative pretreatments are widely used as a preparation for printing. These treatments promote wetting and also damage the fibre surface to facilitate penetration of dye into the fibres. In this paper, treatments with atmospheric helium plasma have been investigated. Colour yields of prints have been measured as a function of pretreatment time, plasma composition and dyestuff type. The effect of rinsing and peroxidization after plasma treatment has also been examined. The colour yields have been correlated with measurements of dye staining after drying and with wetting time on the treated fabrics. Generally, prints were obtained with better colour yields than on untreated wool, but with inferior yields to chlorinated wool.
