According to one embodiment, a spinning apparatus includes a nozzle head, a power generating, and a first atmosphere controller. The nozzle head dispenses a source material liquid from a tip portion toward a collector. The power generating unit generates an electric potential difference between the tip portion and the collector. The first atmosphere controller controls an atmosphere of a first space at a periphery of the nozzle head.

A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) passing the flakes through a PET crystallizer; (E) passing the group of flakes through an MRS extruder while maintaining the pressure within the MRS portion of the MRS extruder below about 18 millibars; (F) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (G) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.

Methods for producing a stretch film are provided, including disposing one or more extruders in fluid communication with a stock of virgin resin; heating the virgin resin to a molten state; delivering the molten virgin resin to a die; and extruding the molten virgin resin through the die onto a casting roll, thereby creating a cast stretch film. Methods for delivering the molten virgin resin onto a casting roll of varying sizes and set temperatures; and of moving a resulting film onto a secondary chill roll of varying sizes and set temperatures, are also provided. Finally, methods for moving the film from either the casting roll or the secondary chill roll onto a slitting assembly, dividing the film using one more interior or exterior slits, and then capturing and gathering the trim waste but not reintroducing the trim waste back into the production process are also disclosed.
