Melt-spinning of multi-component filaments has a center capillary to take the main core material, with additional capillaries to carry the other components to shroud the core at the spinneret spinning capillary

摘要

The assembly for melt spinning filaments, with a number of components, has a capillary (25a) at the center of the spinneret to feed the initial material component (10a) flow. Further capillaries (25c) are near the first, for at least another material component (10b) flow. The assembly for melt spinning filaments, with a number of components, has a capillary (25a) at the center of the spinneret to feed the initial material component (10a) flow. Further capillaries (25c) are near the first, for at least another material component (10b) flow. All the capillaries come together at the main spinning capillary. The material flow at the center capillary is structured to form a coherent core for the spun filament with shaped wings. The other capillaries feed their flows to lie at the filament core, and shroud it at least partially.
