Abstract

Mixed melt is extruded through a dispersing element which is immediately upstream of, and contiguous, to, the die, to disperse the mixture homogeneously before shaping. Pref. the mixture is of at least 2 immiscible polymers. The article is a fibre, and the disperser is between the orifice and the shaping part of the spinneret.
