Bicomponent fibres represent of the new ways for the preparation of synthetic fibres with more variable properties. The polypropylene (PP)‐poly(ethylene terephthalate) (PET) fibre‐forming blend is very interesting because of the improvement of dyeability from bath and some mechanical properties of PP fibres. The new polymer additives containing ester groups which can be added as masterbatches during melting and extrusion processes have been developed in the last years. It has been found that rheological properties of the basic polymer (PP) and polymer additives have a significant role in the blend formation and in spinning. In this work, the influence of some non‐reactive low‐molecular compounds on the processing of fibre‐forming PP‐PET blends and on the properties of blend fibres are presented.
