11840039 · 2023-12-12 · ·

A system comprising: (1) a grinding unit configured to receive and grind recycled PET bottles into a group of polymer flakes comprising up to about ten percent colored polymer flakes and balance substantially clear polymer flakes; (2) a washing unit configured to wash the group of polymer flakes; and (3) an extruder configured to extrude material in a plurality of different extrusion streams. The extruder may be further configured to: (1) receive a concentrate-polymer mixture comprising a mixture of the polymer flakes and a color concentrate; (2) melt the concentrate-polymer mixture to produce a polymer melt; (3) reduce a pressure within the extruder; and (4) pass the polymer melt through the extruder so that the polymer melt is divided into the plurality of extrusion streams. The system may then filter the polymer melt through at least one filter and form the polymer melt into bulked continuous carpet filament.

POLYURETHANE UREA ELASTIC YARN HAVING IMPROVED DYEABILITY AND MANUFACTURING METHOD THEREFOR
20210172090 · 2021-06-10 ·

The present invention relates to a polyurethane urea elastic yarn having improved dyeability and a manufacturing method therefor. Through a process of forming a prepolymer by mixing polyethyleneglycol with polyol and then adding diisocyanate to the same in a prepolymer manufacturing step during the manufacture of a polyurethane urea elastic yarn, the hydrophilicity of the polyurethane urea elastic yarn is improved such that the accessibility of an acid dye is enhanced, thereby enabling the dyeability of the polyurethane urea elastic yarn to be enhanced and an advantage of dye color deepening of a fabric, in which nylon and a polyurethane urea elastic yarn are knitted together, to be expected.

Methods for manufacturing bulked continuous filament from recycled PET
11045979 · 2021-06-29 · ·

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.
