Abstract (en)
[origin: EP0161572A1] 1. Method of making a blended yarn of at least one falsetwist textured filament yarn (1) of synthetic thermoplastic material and at least one spun staple fiber yarn of natural fibers (2), which yarns are together fed to an air entangling nozzle (10) and are therein intermingled with one another at intervals, the filament yarn (1), which is withdrawn from a bobbin, being fed to the air entangling nozzle at a predetermined overfeed relative to the speed of withdrawal of the blended yarn from the air entangling nozzle, characterized in that the falsetwist textured filament yarn (1), after its withdrawal from the bobbin, is first stretched to effect a crimp reactivation before it is fed to the air entangling nozzle (10) at the said overfeed which causes development of maximum crimp in the yarn as it slackens.
