ABSTRACT:
Spun textile yarns from new polyester staple fiber, and downstream textile articles, such as fabrics and garments, made from such, and blends thereof, wherein the staple fiber is of intentionally mixed denier, the higher denier being about twice the lower denier. Such staple fiber and precursor tows are preferably made by spinning filaments of different deniers, and collecting them in the same filament bundle on the same spinning machine, from orifices/capillaries of different diameters and/or throughputs.
