Claims
- 1. A process of forming a bundle of a mixture of different polyester filaments, comprising the steps of:(a) melt spinning a chain-branched polymer to form a plurality of molten filamentary streams; and (b) quenching each molten filamentary stream to form a spun filament bundle comprising a mixture of different polyester filaments.
- 2. The process of claim 1, wherein the polymer is melt-spun through a plurality of capillaries of different cross-section to form a plurality of respective molten filamentary streams.
- 3. The process of claim 2, wherein the molten filamentary streams are quenched to form a spun filament bundle comprising a mixture of filaments of different cross-section.
- 4. The process of claim 1, wherein the polymer is melt-spun through a plurality of capillaries of different flow area to form a plurality of respective molten filamentary streams.
- 5. The process of claim 4, wherein the molten filamentary streams are quenched to form a spun filament bundle comprising a mixture of filaments of different denier per filament.
- 6. The process of any of claim 1, 3 or 5 wherein the filaments are combined to form a rope, and a plurality of ropes is drawn.
