| Abstract: | Conclusions 1. The authors have studied the kinetics of the change in length and internal stresses during drying of freshly-formed hydrated cellulose fibre.2. It is shown that drying of hydrated cellulose fibre is characterised by alternation of two opposing processes: in the first drying stage, when mainly free moisture is removed and the moisture content falls to 25–30%, the thread becomes longer; with a further decrease in the moisture content, due to removal of adsorbed water, the thread becomes shorter.This characteristic of the behaviour of freshly-formed hydrated cellulose fibre must be taken into account when working out the plant procedure and lay-out for continuous-forming and fibre-dressing machines.All-Union Scientific-Research Institute for Synthetic Fibres (VNIIV).
