It was found that incorporation of a third component - LDPE - in the starting two-component blend is an effective method of regulating the spinnability of melts of dispersions and decreasing the effect of superadditive jet spread. The decrease in the degree of jet spread with an increase in the concentration of LDPE is due to accumulation of undeformed particles of disperse phase, formed as a result of destruction of maximally deformed particles of LDPE in the inlet zone and capillary of the spinneret, in the dispersion coming out of the spinneret hole.
