Conclusions 1. On passing through a spinneret orifice, a polypropylene melt behaves as a structured pseudoplastic liquid and its properties are described by flow laws analogous to the flow laws in a capillary viscometer. 2. The dependence of the effective viscosity of a polypropylene melt on its molecular weight, temperature, and shear stress has been established in the form of a semiempirical equation. 3. The effective viscosities of a polypropylene melt on flow through spinneret orifices in the formation of a fibre have been determined. It has been shown that a change in the effective viscosity does not affect the properties of the fibre.
