[0015] figure 1 Schematic representation of an embodiment of a multicomponent melt spinning spinneret of the present invention. figure 2 The direct section structural diagram of the main part of the embodiment of the multi-component melt spinneret of the present invention; image 3 The assembly diagram of the main part of the embodiment of the multi-component melting spinneret of the present invention;
[0016] Multiple spinning devices provide multi-component high polymers, and form multi-component melt-spun hollow fiber composite membranes through connectors and a spinneret. Composite membranes include double and multiple skin layers.
[0017] A plurality of spinning devices arranged in parallel produce melt films respectively. For this purpose, one spinneret is used in several spinning units, whereby hollow fiber composite membranes can be spun in one go by means of several spinning units. A set of spinneret and heat preservation device, the design requirements of the ...
