- Abstract
Regenerated cellulose fibres exhibit strong swelling in concentrated aqueous LiCl/urea solutions. Dependent on treatment temperature and solution composition, fibre diameter increases from 15 µm at room temperature in water to 46 µm in LiCl/urea solution. Treatment in such solution is an alternative to the processing of regenerated cellulose fibres in alkaline solutions. To limit the amount of swelling solution used, the final concentrated solution is formed in a superheated steam atmosphere at 120-130 °C by water evaporation and equilibration. As a result of the treatments the ability of the fibres to hold dye changes and shrinkage of the fabric is observed, while losses in strength and sample weight are not significant.
