Abstract (en)
[origin: WO2023148535A1] A method of manufacturing a wool-like yarn from continuous filaments (1) of polymer material comprises steps of: providing partially oriented, continuous filaments of the polymer; drawing and air texturizing the partially oriented filaments to form threads (5), wherein a first group of straight filaments forms a core (12) of the thread and a second group of filaments are overfed with respect to the first group of filaments to form a hairy sheath (12); and twisting or cabling a plurality of the threads together to form the wool-like yarn (9) to have a weight of greater than 2000 dtex. The resulting wool-like continuous filament yarn is intrinsically UV resistant, antistatic and recyclable.
