Dyeing Properties of Wool Treated with Low-Temperature Plasma Under Atmospheric Pressure

Abstract

Merino wool top was treated with low-temperature plasmas of helium/ argon and acetone/argon under atmospheric pressure for 30 seconds and then 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 blue 83. Dyeing rate and saturation dye exhaustion increased with the atmospheric low-temperature plasma treatments as with the dyeing of wools pretreated with low-temperature plasma by glow discharge of O2 and CF4. In particular, helium/ argon plasma was much more effective than acetone / argon plasma at improving dyeing properties, except for CI acid blue 113.

Influence of Corona Plasma Treatment on Polypropylene and Polyamide 6.6 on the Release of a Model Drug

“…Low-temperature plasma treatment is an effective technique for modifying polymer surfaces [1][2][3][4][5][6][7][8][9]. Plasma techniques are attractive for several reasons: they allow modification of the surface layers up to a depth of several nanometers of the substrate while maintaining its bulk properties.…”

Effects of corona discharge treatment on the surface properties of wool fabrics

“…The appearance of plasma treatment has offered an alternative method. Plasma treatment, as an effective technique for modifying the surface properties, can be used to modify different types of textile products (Zhu * et al, 2002;Sun and Stylios, 2006;Wakida et al, 1993;De Puydt et al, 1989;Lehocky and Mracek, 2006). Corona discharge, as one kind of plasma treatment, has also gained considerable applications in the treatment of metal and polymer materials (Wang et al, 2003;Zhu et al, 2006).…”

Application of atmospheric corona discharge for PES fabric modification

“…It seems to be more advantageous than classical chemical methods and offers distinctive advantages, especially easy modification process control (control parameters being e.g. plasma pressure, discharge input power, modification time and distance between electrode and modified fabric), for details see literature [4], [5], [6], [7]. On the other hand the low-pressure plasma employment is mostly joined with higher financial expenses due to the necessity of the vacuum equipment application and batch processing.…”
