Abstract
PE-monofilaments are produced by the melt-spinning process. The cooling velocity and the stretch-ratio of the melt were varied as characteristic parameters of the melt-spinning process. By increasing the cooling velocity and the cold drawing of the obtained threads, the elastic recovery after a 25% — elongation can be improved to complete reversibility. From tensile test runs a new deformation mechanism can be identified which explains this behaviour. The main features of this deformation mechanism are that no necking occurs during the deformation and that the deformation of the noncrystalline plays an important role. Apparently this mechanism is correlated with an imperfect crystalline structure.
