The deformation behaviour of poly(vinyl alcohol) (PVA) fibres is studied using dynamic mechanical analysis, stress relaxation and uniaxial tensile experiments. Results indicate that the time and temperature dependences of these fibres decrease drastically under the influence of a statically applied stress or strain. These results are discussed in an attempt to relate the deformation behaviour of high-strength PVA fibres to events occurring on a molecular scale.
