Abstract
A flash spin pack for a flash-spinning apparatus is provided in which the pack includes a spin mixture inlet, that communicates with a spin mixture passage, that discharges through a spinning orifice that opens into a slot defined by two opposing faces of the body of the spin pack. The slot is 0.25 mm to 7 mm wide proximate the spinning orifice outlet, 0.25 mm to 10 mm at the slot outlet, and the distance from the orifice outlet to the slot outlet is 1.5 mm to 40 mm. The spin pack may have five or more spinning orifices that each discharge into a different slot so configured.
