Abstract: The swelling and dissolving properties of textile materials are characterised in cotton and regenerated cellulosic fibres of lyocell and viscose (NMMO- and xanthogenate-type). The swelling, fractionation and dissolution mechanisms and their effect on polysaccharide substrate were studied with different solutions, while applying setting treatment. The differences in physical properties before and after treatment were followed by changes in diameter, mass loss and WRV (water regain).
