The nature of the solvent as a factor in the structural and mechanical properties of acetate fibres

Abstract

The supramolecular structure of the wet-spun fibre is known to be formed during the orientation-stretching process in the spinning bath /I-4/ and is consolidated in the subsequent thermal-relaxation operation /5/. An elucidation of the influence of the composition of the spinning solution on the structure and the physical and mechanical properties of the fibre is of considerable interest. This communication represents a report on an investigation of the nature of the solvents as a factor in the structural and mechanical properties of fibres based on secondary cellulose acetate (SCA).
