FIELD: production of fibers, threads and films from polymers, metals and nonmetals (for instance, of glass), particular, spinning from melt and solution by extrusion through the offered spinneret set. SUBSTANCE: spinneret for spinning fibers and threads has polymer distributor, filters, spinneret and seals. Located coaxially and inside the hollow of cylindrical or polygonal prismatic spinneret is polymer distributor, filters, seals and at its ends coaxially sealing covers (flanges) are attached. Distributor has along its axis internal hollow channel communicated with one or two branch pipes for admission of polymer and with radial channels - branches, supplying polymer to the full inner surface of spinneret. EFFECT: higher efficiency. 2 cl, 2 dwg |
