Abstract
Mfe. of conjugate filaments is by forming at least one polymeric extrusion consisting of two viscous liquid polymers arranged as core-sleeve and directing at least one such extrusion into a restricted space and extruding the polymer components through an orifice connected to at least one confined region towards which the polymers flow to form a conjugate filament. Apparatus is also claimed.
