Abstract
A multifilament yarn of polyamide 6, polyamide 6. 6, or polyester is formed from extruded filaments having a diameter of 10-80 mu and a residual strength capacity of 30-70%. The extruded filaments are advanced (after cooling and oiling) through e.g. a pneumatic false twister to intermingle them and form a yarn. The yarn passes at least once around a first pair of cold spaced feed rollers which advances they yarn of 4000-6000 metres/min, and around a second pair of feed rollers which produce a drawn of 0.01 to 1.3. The yarn is wound up under a tension of 0.1-0.2 p/dtex at speeds between 4000-8000 metres/min. The yarn can be wound up at high speeds without becoming deformed and producing a badly would package.
