Abstract (en)
[origin: WO9623091A1] In a process for the continuous production of a multifilament tractile weft yarn of polyester POY filaments for tyre fabric, the polyester POY filament is swirled at an initial titre of 170-260 dtex and immediately thereafter shrunk at an advance of 40-80 % at 230-240 DEG C. The weft yarn obtained has a rough, non-slip surface, a strength of > 7cN/tex, an extension of >/= 180 % and a heat-shrink rate (at 160 DEG C) of +2 % to -2 %.
