Abstract
A method of manufacturing bulked continuous carpet filament from a plurality of polymer flakes comprises: (1) providing an extruder; (2) melting and purifying the plurality of polymer flakes into a polymer stream using the extruder; (3) providing a static mixing assembly downstream of the extruder; (4) adding a first liquid colorant to a center of the polymer stream at a first location before the static mixing assembly or along a length of the static mixing assembly; (5) adding a second liquid colorant to the polymer stream at a second location before the static mixing assembly or along a length of the static mixing assembly; (6) using the static mixing assembly to mix the polymer stream with the first and second liquid colorant to create a colored polymer stream; and (7) forming the colored polymer stream into bulked continuous carpet filament.
