Claim Text:
1. A multiple fiber spinning apparatus, comprising: an extruding unit comprising a plurality of extruders for melting polymer materials supplied into hoppers and then extruding and transferring the polymer materials, wherein each extruder extrudes and transfers the polymer materials into a respective plurality of flow passages; a spin block unit, comprising a gear pump unit comprising a plurality of gear pumps connected to the extruders, wherein at least two gear pumps are connected to each of the extruders, the gear pumps being provided for receiving the polymer materials from the corresponding extruders of the extruding unit and for discharging the polymer materials at a same discharge rate or different discharge rates; and a flow passage unit comprising the plurality of flow passages connected to the respective gear pumps of the gear pump unit for transferring the molten polymer materials through the flow passages; and a spinning nozzle unit comprising a plurality of spinning nozzles, wherein each of said spinning nozzles is connected to one of the gear pumps of each of the extruders by the corresponding flow passage for each of the spinning nozzles to receive the multiple kinds of molten polymer materials and to spin the polymer materials into a fiber.
