Influence of plasma gas on surface composition of low-temperature plasma-treated wool fibre

摘要

Wool fibres have been treated with low-temperature plasma (LTP) with oxygen, nitrogen and gas mixture (25:75 hydrogenitrogen). It is observed that the chemical composition of wool fibre surface varies differently with the different plasma gases used. The surface chemical composition of the different LTP-treated wool fibres has also been evaluated with FTIR-ATR, XPS and saturated adsorption value. The results reveal that the surface chemical and physical compositions of wool fibre change on LTP treatment. The change in compositions might affect the wool dyeing and finishing processes such as shrinkproofing treatments.
