| Abstract: | Conclusions 1. The kinetics of the swelling of PVA fibres in aqueous sodium sulphate solution can be characterised fairly accurately by a first-order kinetic equation.2. The anisotropy of swelling and the initial rate of swelling of PVA fibres depend on the orientation and the supermolecular structure of the fibres. These magnitudes can be used as characteristics of the structural changes in the fibres caused by their drawing.3. The coefficients of the rate of swelling of transverse sections of PVA fibres not subjected to heat treatment are in direct relationship with the strength of the fibres.S.M.
